Sweet Marrow Custard with Vanilla Bean
This sweet custard is seasoned with vanilla and served with fresh fruit, but it's creaminess comes from marrow - a potent source of healthy fats and fat-soluble vitamins. Ask for marrow bones at your local butcher shop or talk to your local rancher.
Prep Time10 minutes mins
Cook Time45 minutes mins
Total Time55 minutes mins
Ingredients
- 2 pounds beef marrow bones (or ¼ cup marrow)
- ¾ cup whole milk (or coconut milk)
- 3 eggs
- 1 tablespoon vanilla extract
- 2 tablespoons honey
- ¼ teaspoon fine sea salt
- salted butter coconut oil or lard, (for greasing the ramekins)
- fresh fruit (to serve)
Instructions
- Bring marrow bones to a boil and let simmer for 10 minutes. While you’re waiting on the marrow preheat oven to 350°F and place four ramekins in large roasting pan.
- In large bowl, whisk together egg yolks, egg, milk/coconut milk, vanilla, honey and salt.
- When the marrow is ready, scoop the bones out with a slotted spoon and place in a bowl to drain. After they’ve cooled a bit use a butter knife to extract the marrow. Place it in a small bowl. Set aside for a minute while you pour the egg mixture into the blender or get out an immersion blender.
- Spoon marrow – but not the oil that has collected at the bottom of the bowl – into the mixture and blend until smooth.
- Pour custard mixture into cups, dividing equally.
- Pour enough hot water into roasting pan to come halfway up sides of cups. Bake until custards are set in center, about 30-35 minutes. Remove from water and allow to cool for a few minutes before serving. Top with fruit, if desired.

One of my very favorite desserts 😊
Natalia says
Hi I know this post was dated years ago but I bought two pounds of beef marrow bones, and was only able to scrape out less than a tablespoon of bone marrow. How would one recommend purchasing enough bone marrow?
Thanks,
Natalia
Olivia says
Hi
This sounds good. But I have a question , please, do you add egg yolk only ?
Deborah says
how many egg yolks? instructions mention both yolks and whole eggs, but you haven't listed yolks on the ingredient list
thanks!
Sarah says
Dear Heather,
What a beautiful recipe this is! I hope you still check this post for I am about to make this but I have two questions that I would like to ask you:
1. Can you use frozen bones for this recipe, and maybe prolong the cooking time, or do I need to defrost them first?
2. Your recipe calls for 3/4 cups of milk. Do you mean 3/4 of 1 cup, or 3 to 4 cups?
Thank you so much!
Janet says
What a fascinating article! I have been buying bones to make collagen rich soup made in a slow cooker. I didn't know what to do with the marrow. I really would like to try this.
Rachael says
I just made this using fresh marrow bones. I thought I strained out all of the oil, but after they cooked each custard had a layer of oil on top! I just drained off the oil into a canning jar to use in cooking. Next time I plan on using gravity to strain the oil from the marrow first and see how that goes. The color of the oil is an amazing gold,can't wait to use it. Now to see if the kids like the custard
Eliza says
Hi Heather, when you say in the ingredient list "egg yolks" as well as "eggs", was that just a typo and you just meant egg yolks? Or do you include the whites in this recipe too? x
Katie says
This turned out so tasty! I used coconut milk and halved the recipe. It made just enough for my toddler and I. Thanks for the recipe!
Annetta says
oh my I am drooling with excitement to make this!!! On the waiting list at my butcher for some marrow bones. Can't wait. Thank you!
Erin says
Oh my goodness, was this delicious! I am obsessed with this recipe at the moment. I start to panic whenever I run out of marrow bones. 🙂 I did change a few things - I used six egg yolks instead of three whole eggs, substituted 1/4 c whole sugar for the honey (it just wasn't sweet enough for me with the 2T of honey, and I didn't like how the honey tasted), and added a scraped vanilla bean. I've made six or seven batches now and I've also found that no matter how much of the oil I pour off the marrow before mixing it into the custard, the finished product still always has a layer of oil on top. So I started just pouring it off before the custard cools, and now my custard is absolutely delicious and not the slightest bit oily. After each batch I throw the marrow bones back into the water with a knuckle bone and make broth, and it's been some of the best beef broth I've ever made. So glad I found this recipe!
sara r. says
ooh I can't wait to try this! I've been looking for marrow recipes for healing my son's teeth, and they already LOVE custard, so this will be perfect 🙂
Nicole says
Hi I was wondering if I could use venison or goat bone marrow? I am having a hard time finding grass fed beef in my area.
Gail says
Has the question about "eggs versus egg yolks" been resolved? Anybody?
Allison says
If you read the first paragraph under "A Perfect 'First Food'" I think it will make more sense.
Susie says
This was SO.GOOD. I'll be doubling it next time and probably making it weekly. This batch didn't last 24 hours, and my 2.5 year old loved it!
Carrissa says
Does it taste beefy? I've been vegetarian for longer than I haven't so I can't recall what marrow tastes like. I'd like to make this for my dad, he needs to build his strength up for surgery, but I know he'll turn his nose up at it if it tastes marrow-y.
jules says
marrow for breakfast makes one feel a little righteous..."uber" healthy. this is a delicious idea. i was going to make a savory custard, but this sweet version caught my eye. i made it with quite a few changes and will be posting about it soon...with credits to you, of course. thanks for the recipe.
Ariela says
What if I/ kids are vegetarian, What can I substitute for the Marrow?

Rachel B. says
I was just about to make this and saw: "In large bowl, whisk together egg yolks, egg," What does this mean? Are the eggs supposed to be separated?
Leah says
In her book Nourished baby she calls for egg yolks, here she calls for 3 eggs I think that is where this confusion comes from
Jessica says
This looks good and I am just about to roast some marrow bones for stock. Can I roast instead of boil the bones and then scoop out the marrow to make this custard?
Leah says
The recipes says to add the yolks and eggs... but the ingredients just call for eggs. Are they supposed to be separated at some point?
Erin says
This is a fabulous recipe! I'll be cooking bones just for the marrow to make this custard. The recipe doubles nicely, so freezing boiled marrow in 1/2 cup portions is great!
Thank you so much!
Cynthia says
Wonderful! This is the first recipe including bone marrow that actually sounds yummy, i've had bowls of it sit in my fridge in the past before finally tossing it out of exasperation (with maybe a little guilt!). One question: for babies under 1, could I substitute maple syrup instead of the honey? Have you experimented with lacuma powder (a very delicious sweetener of Incan origins), that might be good and safe for the very little ones...
Lauren says
Depending on your honey, maple syrup might add more liquid than the recipe needs - try molasses or palm sugar. I've never heard of lacuma powder, so I can't comment there!
Cassandra says
Hopefully someone is still checking comments on this and can answer. I don't have ramekins or any kind of small oven safe cups. Can I use pint canning jars? Or bake it in one large pan set inside another, larger pan?
Heather@Mommypotamus says
I'm not sure about the jars, Cassandra, but I have used the second method before. The baking time will increase, so just watch the center and pull it out when it sets. Good luck!
Cassandra says
Took a risk and tried it in the jars. It was easily split into 2 wide mount pint jars. Also, when I made the marrow, I scooped everything - oil and all - into a jar and stuck in the fridge for a few days. Forgot about the oil part and just spooned 1/4 cup into the blender. Definitely agree with the comment you made earlier - even though I drained the oil that rose to the top, it was still too oily. Daugter is loving it regardless though! I'd like to try it with a warm spice mix, cinnamon, cloves and the such. Maybe chai?
Erika says
Cassandra, I love your idea of a warm spice mix and chai.
Amy says
how awesomely creative! very impressed! can't wait to try it out! thanks for sharing this recipe!
Amy says
how cool and creative! very impressed! can't wait to try it out! thanks for sharing!
Ara says
Hi,
I'm trying to make this now, how do you separate the little bits of brown from the marrow?? I let my bones cool off too long I think. Scooped marrow no problem but don't like the idea of little brown bits in my custard. Thanks for the awesome recipe as always!
Heather@Mommypotamus says
Hi Ara! I bake the little bits of brown in - they rise to the top for a nice golden finish!
Dea' says
Intrigued!
I'm hosting a gals-night tomorrow and many of us have been following the Real Food conference. Now, given that it's 40 degrees in our town this week, I have 3 boys under 4, and have about a dozen mamas heading over for the evening, I'd love to make this tonight (while it's a bit cooler) to serve tomorrow. Would it last? Would it have any 'off' flavors from sitting?
Also, would my beef soup bones work (they all have marrow centers).
Would love it if you're able to reply before this evening! Thanks!! 🙂

Heather@Mommypotamus says
Hi Dea! We always serve this fresh out of the oven as it is best warm, but I often make the mixture ahead of time and store in the fridge until I need it, so you could possibly try that! And yes, your beef soup bones will definitely work!
Dea' says
Thanks!!
(Gonna try it with my gang first as it'll be too hot to serve it warm tomorrow)
Jerri-Lynn says
What are marrow bones and what do they look like and how/where do I find them?
Thank you
Darbi says
This sounds too interesting to not try. I have one question though. What is a marrow bone? I have beef bones in my freezer right now. The bag is a grass fed variety pack. Will these suffice?
Tracee says
I had no idea you could make such a thing with marrow, this is worth a try. I wonder what else I could put marrow into, maybe a pate? I also love the flower decor you made with the berries, I will have to use that.
Kate says
Also, can this be doubled and put all together in a big dish? Any idea how long it would take to bake? I know my family will really like this and I'd like to have it ready to serve at a couple of breakfasts during the week. Thank you again!
Heather@Mommypotamus says
Yes, it can be doubled! The baking time stays the same if you use ramekins, but you can put it in a casserole dish and just pull it out when the center sets.
Kate says
Genius! Thanks! 🙂
Debbie @ Easy Natural Food says
Wonderful idea! I'm going to pin this to make for my 2yo.
Kresha says
Holy schmokes, this sounds good! I'm a sucker for any kind of custard and this sounds like it would be over the top good! Thank you, Heather! (My 7-month-old thanks you too... 🙂 )
Heather@Mommypotamus says
You're so welcome, Kresha! I hope your little one enjoys is as much as mine do!
Minnie(@thelady8home) says
Sound tasty. Adding of the baby food part makes it more better!!
sara says
Do you just ask for marrow bones at the butcher? Are they sort of osso buco-style bones? How much marrow should you get once you scoop it out of the bones?
jb says
Think it would be best to use bones from grass-fed/finished cows.
Dana says
Use what you can get. Never let the perfect be the enemy of the good.
Paula says
I understand your point, but I think it's a health concern, not the pursuit of perfection. I would avoid marrow from conventionally ranched cows, same as I avoid their livers.
jb says
The recipe calls for 1/4 cup of marrow.
Also, using eggs from a local farmer would be better than store bought. And a good grade butter such as KerryGold or Organic Valley Pasture Butter if you can't find raw butter. Coconut oil would give some good flavor.
Dana says
I wonder if ghee would also work. I get a grass-fed ghee at my local co-op.
Christina says
What a lovely idea! I especially like the idea of making it into baby food, but I have just one reservation - my 10 month old is VERY hit or miss when it comes to food, which means I have a hard time justifying spending the time and effort for things like this. So two questions - how long does this keep for, and do you have any tips for mamas of skinny babies who prefer to play and play and eat things off the floor instead of learning how to eat real solid food? Thank you!
Cassandra says
Babies don't "learn" how to eat real solid food, as in they don't need to set aside time to practice eating - it's not like playing a violin. When they want food, they will eat it. Eating is actually pretty inherent, the only thing that really changes is gaining skill with utensils. That will come with normal fine motor skill development, not something that has to happen separate from the rest of development. If your baby doesn't have interest, don't bother. Baby should still be nursing (bottle or breast).
Christina says
This has been my philosophy pretty much, I think it's just the fact that she still gags on anything semi-solid (even pureed squash), and just doesn't seem to grasp the concept of picking up food and putting it in her mouth (despite the fact that she likes to do that with all the other stuff she finds on the floor), and is small for her age that have made me feel a little desperate. She's pretty much exclusively nursing at 10.5 months (and crawling and walking!), and she's not even a big nurser. It also doesn't help that her big sister loves both nursing and eating and is a chunk, so that's what I'm used to. Thanks for the reassurance that these things will come with time 🙂
Kimberly says
Christina, I too, always thought that of course, all babies would want to eat... something, but my daughter (now 2 1/2) has been a great teaching experience for me. Like your second, she has been more interested in EVERYTHING about her life, except eating food. She nurses well and has highly preferred that to anything else. What I have done, since, like you, I was getting worried about her tiny, skinny frame, is to just be consistent, every day, at least one "meal" (and for me the last almost 2 years, this has been my major chore of every morning), to have her eat something highly nutritious, maybe a bit of liver, Kefir, or what I have on hand. The last several months I have made her a special smoothie in the Vita-Mix with some fruit, fruit juice, green veggies, fresh Kefir cream, pastured raw egg yolks, Maca, sea vegetables, Spirulina, Chlorella, a vitamin C powder blend of various dried berries, etc, and after having her "fishy-ning" (Fermented Cod Liver Oil/High Vitamin Butter Oil blend), she prefers to eat her smoothie "greens" from the syringe like the oils, and I help her count. I make up a full Vita-Mix container, put it in jars in the fridge and it lasts several days to a week depending on how fast she eats it. I vary the recipe a bit each time. She has recently been getting better, but only 2 months ago, it was taking me up to 5 hours to get as many as 10 bites actually into her body. LOTS of patience, love, encouragement, consistency, choices and consequences, and lots more love... wow, good thing I didn't have to work outside the home. Folks were telling me I should just let her eat things they gave their babies: cookies, crackers, junk foods that are designed to appeal to babies to get her in the habit of eating, but I don't want my baby sick like theirs are, so I figured it out between us. 🙂 She now eats between 30-40 syringe fulls (teaspoons full) every morning and we are getting several bites in at night with bits of our dinner she shares from our plates. She has increased her appetite desire, put on muscle and just enough softness over her still-lean frame, begun to gain weight and height and increase energy. Oh, what a happy Mama am I!
To Summarize, at least a bit of SOMETHING high quality and nutritive, EVERY DAY, CONSISTENTLY.
Oh yeah, I just remembered, around the beginning of this year, for about 6-8 months we were giving her "caviar" little fish eggs from the fish store or a sushi restaurant, she usually loved it and it did help her put on weight from being so skinny, kind of boosted her. At the same time, what I really wanted was FRESH fish eggs, as those we could buy her were "seasoned" with MSG, red 40 and something else, plus they were frozen. Still, the difference in her energy, mental focus and interactive connective ability, vs. listlessness and teary breakdowns was huge!
Bless you and your daughter in your food journey!
Anastasia says
I'd go easy on Spirulina, Chlorella and Maca. Why are you giving maca to a baby? Isnt it supposed to regulate hormones in adults?
Dana says
You could always eat it if he doesn't, so it's still worth the time. YOU ARE WORTH IT, MAMA! And if you're nursing him, he'll get the benefit of it anyway. 🙂
Heather@Mommypotamus says
Oh, I wish I had an answer for you Christina, but it's never lasted long enough in our house to find out! On the subject of babies and solids, though, I do have one tip: Definitely let them eat things off the floor! In this post I wrote about starting solids there's some good info on why it's beneficial, and you may find the section on when my babies started showing an interest in food reassuring (it was way after 12 months!). Here's the link: http://www.mommypotamus.com/when-should-my-baby-start-solids/
jo says
just wondering, you boil the marrow bones in water? if so, does the water need to cover the bones?
Heather @ Mommypotamus says
Hi Jo! Yes, the bones need to be submerged in the water.
Erin says
wondering the same thing! but the marrow doesnt leak into the water? i cant wait to try this!!!
Heather@Mommypotamus says
It doesn't leak, Erin, but it does soften enough so that it is easily extracted 🙂
ValerieH says
Do you save the water for making broth? There has got to be some nutrition left in the water.
This is such a cool idea.
Heather@Mommypotamus says
Yes, I definitely do Valerie!
Priscilla says
Why not use the oil from the marrow? Will it just alter the recipe? Or it it unhealthy? Can I use it for something else? Thanks!
Heather@Mommypotamus says
Hi Priscilla! The oil from the marrow is wonderful in scrambled eggs or baked into some muffins, but makes this custard too oily if included 🙂
Priscilla says
Sounds tasty! Thanks
Annetta says
So should this oil be saved in a jar with lid for future use like bacon fat?
Nancy says
YES! Definitely don't throw it out. Use it for cooking eggs, stir fries, etc.
