Soup. It’s one of the simplest and most comforting pleasures of the cold weather season, and when I spied a bag of dried black beans in the back of my tall pantry a couple months ago, I thought, “Great, this will be easy!” Soak them overnight, drain and rinse, then cook them up with a few aromatic veggies, spice and broth, right? Well, as you may have already guessed, this one didn’t go quite that smoothly. And it’s my own fault for not paying attention to the “best by” date on the side of the cellophane bag. Oops.
Though dried beans are easy, there are a few guidelines, and using them up before they get too old is one that should not be overlooked. I was already more than a day into it, though, when I realized that my beans had “expired” more than two years earlier. I’m thankful that I was able to call for backup, and I received expert advice that rescued my black bean soup, which turned out as delicious and comforting as I had hoped.
But before I get to the rescue of my soup, let’s talk about how things should go when making soup from dried beans, and hopefully I’ll remember my own advice next time!
Prep the beans
The first rule of thumb is to rinse and sort through the beans, just in case there is a random stone or other debris in the bag. I have never found one, but I’m certain that I would split a molar if I skipped this step even one time. So, sort them I do, under cold running water, and then I dump them into a deep pot with plenty of water for an overnight soak.
There are many viewpoints about whether the soak is necessary (spoiler alert— it technically isn’t), but the “shortcut” instructions for skipping the soak always leaves me with beans that are too “al dente” for my taste, and they take forever to cook (turns out mine would, anyway, but I’ll get to that).
Draining soaked black beans is especially dramatic because of the purplish color of the soaking water, but it is usually cloudy and foamy, too, and this is because you’re eliminating some of the complex sugars that make beans difficult to digest. The soak gives the beans a chance to let loose some of that gas (so you don’t have to). 😏
Season every layer, except this one?
If there is one myth we should all unsubscribe from, it is the notion that salt is an enemy to dried beans, and that using it too soon will keep the beans from softening. Honestly, who are the bean police making up these rules? I’ve heard this one my entire adult life, but it has been proven to be untrue. Some cooks even add salt to the soaking water, and there is nothing wrong with doing so. If you wait until the very end to add salt— as so many recipes insist you must— then you’re prone to end up with beans that taste unseasoned and overly salty at exactly the same time. You might guess from this statement that I’ve learned this the hard way, and you’d be correct!
I placed my beans, covered with water, over medium heat with a couple of bay leaves, and got to work prepping the aromatics that would flavor my soup: onions, garlic, celery, red bell pepper and jalapeño.
The seasonings came next. I pulled out a small skillet to toast up some whole cumin seed. Toasting seed spices is an easy way to elevate their flavor, and a quick crushing in my mortar and pestle revealed a most potent aroma. Add to that a generous sprinkling of chipotle chile powder, plus salt and pepper (of course), and my kitchen already smelled inviting!
Under normal circumstances, those veggies would go into the pot after about an hour, when my beans became tender. But my ignorance about the best-by date on my beans is where the trouble came in. After 20 hours of soaking and two solid hours of simmering, my beans were still very firm. Not crack-a-tooth firm, but firm enough that they didn’t budge when I pressed on them with the back of a fork. Dang it! I almost scrapped the whole thing, and I had to come up with another plan for dinner. I needed help.
Thank goodness for foodie friends!
I am ever appreciative for the friendships I’ve made since I began food blogging, and on that day, my gratitude for Dorothy at The New Vintage Kitchen was multiplied. Dorothy is a revered graduate of the “waste nothing” school of culinary excellence, and I reached out with a text message, figuring if there was a way to salvage my beans from this debacle, she would point me toward it.
“I’d probably add a bit of baking soda and keep cooking them,” Dorothy texted me. She also encouraged me to “go ahead and salt them.” I was grateful for that advice, too, because old habits die hard.
And just like that, I was back in business! Thanks to the alkaline nature of baking soda, my beans were softened about an hour later, and I added a couple of strips of turkey bacon for smoky flavor, all my sautéed veggies, plus some low-sodium veggie broth. Soon enough, my soup was ready for final touches! I took my immersion blender for a 20-second spin and stirred in some tomato paste to perk up the flavors.
By the time the bean crisis was averted, I had already pivoted to Plan B for dinner that night, so I stashed the soup in the fridge and rewarmed it the following evening. Soup is always better on the second day anyway, and this big ol’ bowl of yum made my hubby and me very happy.
The tip that keeps on giving…
The story doesn’t end with my own soup, and this is the beauty of sharing foodie tips with fellow cooks. A few weeks after my own panic attack, I got a text from my cousin, who had run into trouble making ham and bean soup. Brad had combined his beans with ham and vegetable broth and dumped in a can of—yikes— diced tomatoes before he noticed the recipe said to hold that last ingredient til the end. Unlike salt, acidity is an enemy to dried beans, and Brad described his panicked effort to strain the beans out of the mixture a “fool’s errand.” This is such a frustrating moment for any cook, and I shared how my black bean soup was saved by a quarter teaspoon of baking soda.
“Give it a try,” I suggested.
Brad texted me the next day. The baking soda had neutralized enough of the acidity of the tomatoes; the beans softened and his soup was saved! He also shared his success story with a buddy who complained that his chili made with dried beans never came out quite right, and he’s going to try the baking soda trick next time, too!
One of these days, I’m going to make a list of all the brilliant uses for baking soda in the kitchen. I’m betting that my fellow cooks have other examples to share. Until then, stay warm and enjoy this comforting black bean soup. A big ole bowl of yum!
Black Bean Soup
This easy soup is smoky and flavorful, made with simple ingredients and so comforting on a cold winter's night!
Ingredients
- 1 lb. dried black beans, sorted, rinsed and soaked overnight
- Plenty of water, for soaking and cooking
- 2 dried bay leaves
- 1/4 tsp. baking soda (see recipe note below)
- 2 Tbsp. extra virgin olive oil
- 1 medium sweet or yellow onion, chopped
- 2 stalks celery, strings removed and chopped
- 1 medium red bell pepper, seeded and chopped
- 3 cloves garlic, finely chopped
- 1 jalapeño, seeded and finely chopped
- Kosher salt and freshly ground black pepper
- 1 tsp. cumin seeds, toasted and ground
- 1 Tbsp. chili powder (I used ground chipotle chiles)
- 3 strips smoked turkey bacon
- 2 cups low sodium vegetable or chicken broth
- 2 Tbsp. tomato paste
- Sour cream and scallions, for serving
Directions
- Drain and rinse the soaked beans, transferring them into a large, heavy-bottomed pot. Cover with at least two inches of cold water. Add a teaspoon of salt and a couple of bay leaves to the pot. Bring to a slight boil, then cover and simmer for about one hour until beans begin to feel tender.
- Place a sauté pan over medium heat and add olive oil. Add onion, celery and pepper to the pan with a generous pinch of salt and black pepper. Sauté for about 3 minutes, until they are softened and slightly translucent. Add garlic and jalapeño and cook 2 more minutes. Season with cumin and chili powder. Set aside to cool.
- When beans are tender, add turkey bacon to the pot, along with broth and sautéed vegetables. Simmer until the mixture is hot throughout and bacon is shriveled. Remove bacon strips and bay leaves.
- Use an immersion blender to purée the soup. It can be smooth or chunky, to your liking. Alternatively, transfer a cooled portion of the soup to a conventional blender and stir the pureed portion back into the pot. Use caution, and do not purée a hot liquid in a closed blender container.
- Stir in tomato paste and adjust seasonings to taste.
- Serve with a swirl of sour cream and chopped scallions.
