A bowl of black bean soup with garnishes.

Several years ago, while cooking my way through the soup chapter of Twelve Recipes, I discovered Cal Peternell’s black bean soup.

What I loved about the recipe was the simplicity of the flavors: sautéed onion and garlic, toasted cumin seed and crushed red pepper flakes. But there was an element of surprise, too, lent by the zest of an orange. Somehow, through all of the bold, beany flavors, the citrusy brightness prevailed.

Friends, if you’ve been reading for awhile, you know I’m a bean briner and a soaker. But I recently learned that with black beans, brining and soaking is not necessary. And in fact, it might be preferable both taste and texture-wise not to soak/brine.

These days my preferred method for cooking black beans (and chickpeas, too) is in my slow cooker or Instant Pot (find instructions for using the IP in the slow cooker recipe). Both methods work beautifully. Look at these perfectly cooked black beans:

Description

From Cal Peternell’s Twelve Recipes

Notes: After reading an article on Serious Eats about soaking vs. not soaking black beans, I’ve stopped soaking them, and I’ve really taken to cooking them in my slow cooker or pressure cooker: 

To cook the black beans using an Instant Pot: Place 2.5 cups dried beans, 2 teaspoons kosher salt, and 8 cups water in the inner pot of your Instant Pot. Secure lid in place. Turn valve to Sealing.  Select manual, high pressure, and adjust the time to 25 minutes. When the time has lapsed, allow the pressure to release naturally, which is when the silver button on the lid drops.

To cook the black beans using a stovetop pressure cooker: Place 2.5 cups dried black beans in the pressure cooker pot with 8 cups water and 2 teaspoons salt. Bring up to pressure over high heat. Reduce heat to low and allow beans to cook for 25 minutes. Remove pot from heat and allow the valve to release naturally.

You, of course, can simply simmer the beans stovetop.

Notes: 

  • 2.5 cups (about a pound) of dried beans will yield 6 cups of cooked beans.
  • If using canned beans, drain and rinse them.

Ingredients

  • 3 tablespoons olive oil
  • 1 large red onion diced
  • 1/2 teaspoon kosher salt, plus more to taste
  • 1 tablespoon toasted cumin seeds
  • 1/2 teaspoon crushed red pepper flakes
  • 4 garlic cloves, sliced or minced
  • 1 strip orange peel (removed with a peeler) or the zest of an orange (grated with a microplane)
  • 6 cups cooked black beans (2.5 cups dried), see notes above, liquid reserved
  • 1 quart water, vegetable stock, or chicken stock or, if you cooked your beans from scratch, the bean cooking liquid
  • 1/4 teaspoon dried oregano

for serving: 

  • sour cream
  • chopped cilantro
  • thinly sliced scallions
  • lime wedges

Instructions

  1. Heat a large pot over high heat. Add the oil and all but a couple of tablespoons of the diced red onion (for garnish). Add the salt, cumin seed, red pepper flakes, and immediately turn the heat to low. Cover, and cook for 15 minutes, checking and stirring periodically to ensure the onion isn’t browning.
  2. Add the garlic and orange peel or zest. Raise the heat to high and stir for half a minute more. Add the beans, the water, and enough reserved been cooking liquid to ensure the beans are submerged. Crumble in the oregano. Bring to a simmer. Adjust the heat to allow the soup to simmer gently for 30 minutes.
  3. Taste. Add more salt, cumin, garlic, red pepper flakes, and/or oregano to taste. If you prefer a thicker texture, purée some of the soup in a blender or food processor. Personally, I love the texture of the soup as it is.
  4. Serve with all the fixins’: scallions, reserved onions, cilantro, sour cream, and fresh lime to taste.
