Canned black beans or dried?

It's totally up to you! If you're in a hurry, canned beans work just fine. Eden Organics is an amazing canning company that does soak their beans for several hours before cooking so you'll get the same benefits by buying their products. I linked to them so you can read more about their amazing practices, not because I'm sponsored by them!

Soaking reduces the phytic acids, tannins, and polyphenols in legumes, grains, nuts, and seeds that prohibit the body's ability to absorb proteins and minerals such as iron, zinc, and calcium. There's lots more info in my post on Dried Beans.

So, I guess this could be another plug for menu planning, which I am admittedly not great at! But benefits such as these spur me to be better!

For this recipe, you can either cook the dried beans ahead of time (my preference ... in the InstantPot) or you can add them to the soup to cook there. The second option requires that you start the soup 1-2 hours before dinner time so the beans have time to cook through ... and it might require a bit more chicken broth so be sure to have extra on hand.

What are poblanos?

Charred poblanos on the cutting board to chop

Poblanos are one of my favorite peppers! They tend to be on the mild side although sometimes, they can pack a bite. Poblanos are dark green in color and about 4 inches long. They turn red when they ripen and are called ancho or chile ancho when they are dried. Poblanos are the pepper used to make chile rellenos, poblanos stuffed with cheese! Another favorite of mine! And check out the related recipes below for a couple of other dishes using poblanos right here on my site.

For the purposes of this recipe, the poblanos are first charred.

Three ways to char poblano chiles:

Broil them under the oven broiler on a baking sheet or in a cast iron skillet, turning occasionally until blackened, about 8-10 minutes.
Put them on a very hot grill, turning consistently until they are blackened.
If you have a gas stove, put them right on the grate over the flame and turn them as they blacken.

Cover them and let them steam for about 15 minutes. If you want, you can remove some of the blackened skin. Personally, I don't mind having some of the smoky flavor left. Then remove the seeds and chop the peppers to add to the soup later.

Let's make the soup base

The soup base is onions, garlic, tomatoes, and a dried ancho. Cook the onions slowly, not browning them, then add the garlic.

If you have a dependable immersion blender, you can add the tomatoes and ancho to the pot, then blend in the pot. If not, transfer the onions and garlic to the jar of a blender, add the tomatoes and ancho, and blend.

Isn't that gorgeous!? You let it thicken a bit over heat, then add some broth. Use chicken or make it vegetarian by using vegetable stock.

If you are using soaked, uncooked black beans, add them now and let the soup cook for 1-2 hours depending on the size of the bean and how long they soaked. You'll also need extra broth because the beans will absorb the liquid as they cook.

If you are using canned beans or soaked, cooked beans, add them 5-10 minutes before serving, along with the charred poblano peppers, just to warm them through.

How to serve Black Bean Soup with Poblanos

This isn't a Mexican soup per se, but it tilts in that direction so I love something "corn" and crunchy with it ... tortilla chips or Crunchy Cast Iron Cornbread. Top it with queso fresco (or feta cheese if you can't find queso fresco) and serve it with lime wedges to squeeze over. So good!

Ingredients

2 poblano chiles
1 Tablespoon oil
1 large onion about 1½-2 cups
8 cloves garlic crushed and chopped
1 28-ounce can diced tomatoes use fire-roasted if you like
1 large dried ancho chile, stemmed, seeds removed
4 cups chicken broth homemade, store-bought, or vegetable (more if you choose to cook the beans in the soup rather than before ... see notes and instructions)
Salt to taste
2 14.5-ounce cans black beans or 4 cups home cooked beans (See notes)
½ cup queso fresco or feta cheese
lime wedges for serving

Instructions

THREE WAYS TO CHAR THE POBLANO CHILES:

Broil them under the oven broiler on a baking sheet or in a cast iron skillet, turning occasionally until blackened, about 8-10 minutes.
OR Put them on a very hot grill, turning consistently until they are blackened.
OR If you have a gas stove, put them right on the grate over the flame and turn them as they blacken.
Once they are charred, transfer them to a bowl, cover, and let them steam 15 minutes. Peel, seed, and finely chop. Set aside.

TO MAKE THE SOUP:

Heat a Dutch oven over medium heat. Add the oil, then the onions. Cook, stirring occasionally, until onion is soft 15-20 minutes. Reduce the heat if browning starts to occur. Add the garlic and cook another minute.
Transfer the onions and garlic to a blender jar. Add the tomatoes and ancho chile and blend till smooth. (Alternatively, you can add the tomatoes and ancho chile to the pot and blend with an immersion blender.)
Return the tomato mixture to the saucepan and cook over medium-high heat, stirring often, until thick, 6-8 minutes. Stir in the broth and season with salt.
IF you are using soaked, uncooked black beans, add them now. Bring to a boil, reduce heat and simmer until the beans are tender. This could take 1-2 hours, depending on the size of the bean and how long they soaked. Check occasionally and add more chicken broth as needed. Just before serving, increase the heat and allow the soup to thicken slightly, 10-15 minutes, then add the poblano peppers.
IF you are using canned beans or soaked, cooked beans, add them 5-10 minutes before serving, along with the charred poblano peppers, just to warm them through, 5-10 minutes
Serve soup topped with queso fresco (can sub feta) and limes alongside.

Notes

Use vegetable broth for a vegetarian option.

If you want to cook the beans in the soup, allow 1-2 hours of cooking time, and have extra chicken broth on hand. The uncooked beans will absorb a lot of the soup's liquid so you'll need more.

To arrive at 4 cups of home cooked beans, soak a pound of black beans overnight, and cook on the stovetop for about an hour, or in an InstantPot for 20 minutes. Drain before adding to the soup.
