Lentil-chestnut soup

Let's face it, any woman (or man) who works, presuming s\he's the one in charge of the cooking duties in the house, appreciates a one-pot meal. A one-pot meal not only has to fit in one pot, but the contents of said pot should be nourishing and satisfying enough so that you do not find the people you are trying to feed looking forlornly in the refrigerator one hour after dinner.

A soup that falls into the hearty category like this one, fulfils that requirement admirably. When the weather turns cold, there is nothing like soup with legumes in it to warm your tummy as well as filling it.

Lentils are the handiest legume ever, since you don't need to soak them beforehand. You can just throw them into a pot and say, 20-30 minutes later, they are nicely cooked. Esau's potage (see Old Testament) is supposed to have been made of lentils. Lentils also have a slightly peppery flavor which perks up the flavor of the soup. For this soup I prefer to use red lentils, but the grey ones work fine too.

The other main ingredient is chestnuts. This is a bit tricky, actually. If you have time and patience, you can buy raw chestnuts and either boil them or roast them (on your open fireplace, if you have one, in a tin made for this purpose, or else wrapped in double-triple-layers of foil and places near the edge of the fire). But who has the time for that? Here in Switzerland, as well as in Austria, Germany and France, it's easy to buy bags of "heisse Marroni" (hot roasted chestnuts) on the street during the cold months. You do need to peel them but the shell does pop off easily. Try not to pop too many in your mouth while you peel them.

If you have money to burn, you can substitute chestnuts-in-honey or syrup or whatever you can find at your local gourmet store. This is what Nigella Lawson does in the original recipe from which this recipe has been freely adapted. I would not be so crazy as to use real, beautiful marron glacé though. Here we can also buy peeled frozen chestnuts at the supermarket, which do the job just fine.

If you don't have any chestnuts, I would (and have) substitute an equivalent amount of cut up sweet potatoes, or Japanese-type squash (kabocha). Butternut would be okay too. You just need a rather dense, sweetish, floury ingredient. Plain potatoes lack the sweetness factor.

For this sort of soup you don't need to get too fussy about the stock. Plain water plus a vegetable stock cube does the job, provided you start with the sauteed vegetable mix.

This is a pureed soup, so you need a stick blender. Believe me, a stick blender is well worth getting, and they are really cheap. Even if you have a food processor or blender, it's way easier to just puree a soup in the pan. I don't worry about tiny little lumps being left - it just makes it more rustic and satisfying.

Lentil-Chestnut Soup

  • About 1 cup of dry lentils, or if you want to measure about 200 grams / 7 oz.
  • About 2 cups of peeled, cooked chestnuts, or cut up sweet potato, or Japanese kabocha squash
  • 1 medium onion
  • 1 celery stalk or about 1/3 of a large peeled celery root
  • Butter or oil
  • Bay leaf
  • Dried or fresh thyme
  • Vegetable stock cube (I just use Knorr Gemüsebouillon)
  • molasses or honey

Finely chop the onion and celery. (I just whiz in the food processor.) Sauté in butter or oil until it's all limp and just turning towards caramel color.

Add about 6-8 cups of water, 2 stock cubes, a bay leaf and about 1 tsp (a good pinch) of thyme. Bring to a boil and add the lentils. Lower heat and simmer for about 20 minutes or until the lentils are soft. Overcooking a bit is fine, even desirable.

Add the chestnuts or potatoes or squash and cook for about 15-20 minutes more until tender.

Carefully fish out the bay leaf. Whiz the whole thing with your stick blender until reasonably smooth. Taste to see how much salt and pepper you need to add. At the last minute add about a tablespoon of dark molasses or honey. This just enhances the sweetness underlying everything.

Serve with a good crusty bread.

Cooking time: about 45 minutes total, most of that for just simmering on the stove.
