Marrow bean soup is fragrant with a simple broth, fresh herbs and root vegetables. Celeriac and potatoes give the soup a bright flavor, and lovely texture.
Why We Soak Our Beans
I begin each of my bean and lentil soups the same way. First, I pick over the lentils and rinse them well to remove stray clumps of dirt and little stones that disguise themselves as beans. I dump the beans into a big bowl, and cover them with hot water to allow them to soak and soften at least overnight and up to a day.
Soaking beans in the old-fashioned recipe results in two improvements: one culinary, and the other nutritional. Soaking beans softens them, allowing them cook more quickly, more evenly and with tender results. Soaking beans also improves the bioavailability of trace minerals such as iron, magnesium, phosphorus, zinc contained in beans.
Keeping the soaking water warm to hot helps to ensure that antinutrients that otherwise bind up these micronutrients, making them difficult to fully absorb, are deactivated. Beans are also an excellent source of folate, a B vitamin that is critical for women of reproductive age for its ability to support reproductive health and in the prevention of neural tube defects.
The Beauty of Broth
Bone broth is a cornerstone of our diet, and of my family’s daily meals. Its flavor soothes, while it also helps to support systemic wellness. Broth is rich in both trace minerals, and in gelatin – which helps to support digestive system health and skin health.
Finding Marrow Beans
Marrow beans are plump white beans about the size of your pinky fingernail. An heirloom bean, they can be difficult to find in many grocery stores, but they’re creamy texture and unique flavor that tastes lightly of bacon, and despite their rarity, they’re worth finding. I order my marrow beans online, about 10 pounds at a time and keep them in the pantry.
Marrow Bean Soup with Pale Vegetables
- 1 cup marrow beans
- 1/4 teaspoon baking soda
- 2 tablespoons ghee
- 1 large leek white and light-green parts only, sliced thin
- 1 clove garlic sliced thin
- 2 quarts chicken bone broth
- 1 pound celeriac peeled and chopped into bite-sized pieces
- 1/2 pound parsley root peeled and chopped into bite-sized pieces
- 2 pounds Yukon gold potatoes peeled and chopped into bite-sized pieces
- Fine sea salt
- Dump the marrow beans into a large mixing bowl, cover them with hot water by 2 inches and stir in a pinch of baking soda. Cover the bowl and let them soak for at least 18 and up to 24 hours. Once or twice as the beans soak, drain away the soaking water and replenish it with hot water. After they’ve soaked at least 18 and up to 24 hours, strain the beans and set them on the countertop for later. Discard the soaking water.
- In a heavy stock pot, melt the ghee. Stir in the leeks and garlic, sautéing them until softened and fragrant – about 4 minutes.
- Pour the stock into the pot, and stir in the soaked beans. Simmer, covered, for 1 hour. Stir in the celeriac, parsley root and potatoes and continue simmering the soup a further 30 to 45 minutes or until the beans and vegetables turn tender and yield when pierced by a fork. Ladle into soup bowls, and serve hot.
