Sweet potatoes are one of the best sources of vitamin A on the planet. And combining this amazing nutrient- and color-rich veggie with peanut butter spells healthy, tasty comfort food. Did you know that combining sweet potato with fat increases it’s bioavailability (the amount that gets absorbed by the body)? The combination of peanut butter (fat) and sweet potato perked up by a few spices tastes heavenly in this West African sweet potato & peanut soup. If you are allergic to peanuts, no worries. I also have a a nut-free version of this soup.
Notes on using nut- & seed-butters
If you have eaten this soup in restaurants, you have probably noticed that it is often over-loaded with peanut butter. The world of the wide web is replete with West African peanut soup recipes that suggest using about 2 tbsp to 2.5 tbsp peanut butter per serving. While such offerings may taste great due to high fat content, it is hard to enjoy these regularly without packing unnecessary pounds. This is because nut and seed butters are a calorie-dense food, with most of the calories coming from FAT. While fat is an essential nutrient in our diets (stay tuned for demystifying fats in our diets), excess of it can not only lead to (unintended and unwanted) weight gain, a diet consistently high in dietary fat is also associated with heart disease and certain types of cancers.
Therefore, in this soup I definitely wanted the peanut butter flavor but reduce the amount of fat to make it more nutritionally balanced to enjoy it on a regular basis rather than as an occasional treat. One trick is to replace extra peanut (or seed) butter with any type of white beans, which mimic the texture of butter and take on the the flavor of whatever they are added to. In this West African sweet potato and peanut soup, I have replaced some amount of peanut/seed butter with cannellini beans.
To make nut-free version
If you are allergic to nuts and peanuts, definitely try the peanut-free version. As one of the family members is allergic to nuts, all of my recipes at home have two versions–nut/peanut and seeds. To make it peanut free, replace peanut butter with sunflower seed butter in equal amount and top with toasted (or raw) sunflower seeds.
