Slow Cooker Chicken Tortilla Soup (Smoky, Bright, All Day Easy)

Slow cooker chicken tortilla soup is a full meal in a bowl. The broth is tomato based, smoky from chipotle and fire roasted tomatoes, and just tangy enough from lime to keep you coming back for another spoonful.

The chicken goes in raw and cooks right in the broth, so it picks up every bit of flavor and shreds into tender strands. Black beans and corn make it hearty, and the toppings turn it into something you build at the table.

Best of all, the active work is about 15 minutes. Dice an onion, open a few cans, and the slow cooker takes it from there.

Crisp tortilla strips are the finishing touch that gives the soup its name. They take 10 minutes in the oven or a skillet and are worth every one of them.

Why this recipe works

• Fire roasted tomatoes and a spoonful of chipotle in adobo add smoky depth without a single browning step.
• Chicken thighs stay tender over the long cook, and cooking them in the broth seasons both the meat and the soup.
• Beans and corn are added toward the end so they hold their shape instead of turning soft.
• Lime juice and cilantro stirred in at the end restore the brightness that a long simmer mutes.
• Baking your own tortilla strips gives you a crunch that store bought chips cannot match, and it uses up tortillas you already have.

Ingredients you’ll need

The soup is built on chicken, broth, tomatoes and aromatics. Onion, garlic and a jalapeño give it a savory base, and cumin, chili powder and smoked paprika round out the seasoning.

Fire roasted diced tomatoes bring a gentle char. One or two chipotle peppers in adobo bring smoke and heat. Black beans and corn are stirred in near the end.

For toppings, plan on corn tortillas for baking into strips, plus avocado, shredded cheese, sour cream, lime wedges and cilantro. Radishes and pickled jalapeños are optional but excellent.

Nothing here is hard to find. A regular grocery store carries every item, and most of the pantry ingredients keep for months, so you can stock up once and make this soup several times through the season.

Ingredient notes and smart substitutions

Chicken

Use 1 1/2 to 2 pounds of boneless skinless thighs for the juiciest result. Boneless breasts work if you pull them at the early end of the time range. Whatever you use, the chicken must be fully thawed before it goes in the pot. Frozen chicken lingers too long at unsafe temperatures in a slow cooker.

Fire roasted tomatoes

Two 14.5 ounce cans of fire roasted diced tomatoes are the flavor shortcut here. Regular diced tomatoes work in a pinch. Add 1/2 teaspoon extra smoked paprika to make up for the lost char.

Chipotle in adobo

One minced pepper plus 1 tablespoon of the sauce gives medium heat. Use two peppers for a spicier pot. If you do not have chipotles, use 1 teaspoon chipotle powder or an extra teaspoon of smoked paprika with a pinch of cayenne.

Broth

Use 6 cups of low sodium chicken broth. If your broth is fully salted, hold back the added salt until the end and taste before seasoning.

Beans and corn

One 15 ounce can of black beans, drained and rinsed, and 1 1/2 cups of frozen corn is the standard mix. Pinto beans swap in fine. Fresh corn cut from two ears is a nice upgrade in early fall.

Tortillas

Corn tortillas make the best strips because they bake up crisp and stay that way in the broth longer than flour tortillas. Six tortillas make enough strips for 6 to 8 bowls. Thick cut tortilla chips are the backup plan if you skip this step.

How to make it

1. Load the slow cooker

Add the diced onion, minced garlic, jalapeño, both cans of tomatoes with their juice, the minced chipotle and adobo sauce, all the dried spices and the broth to a 6 quart slow cooker. Stir well so the spices dissolve.

2. Add the chicken

Season the thawed chicken lightly with salt and pepper and lower it into the broth. Make sure the pieces are submerged so they cook evenly and stay moist.

3. Cook without peeking

Cover and cook on LOW for 6 to 7 hours or on HIGH for 3 to 4 hours. Leave the lid alone. Each time it comes off, the pot loses heat and the timer effectively resets by 20 to 30 minutes. The chicken is ready when it reads 165°F and pulls apart easily.

4. Shred the chicken

Lift the chicken onto a cutting board and shred it with two forks. Return it to the pot along with the drained black beans and the corn.

5. Finish the soup

Cover and cook on HIGH for 20 to 30 minutes so the beans and corn heat through. Stir in the lime juice and chopped cilantro. Taste and adjust the salt.

6. Bake the tortilla strips

While the soup finishes, heat the oven to 400°F. Stack the corn tortillas, slice them into 1/4 inch strips, toss with 1 tablespoon of oil and a pinch of salt, and spread on a sheet pan. Bake for 8 to 12 minutes, tossing once, until golden and crisp. They crisp further as they cool.

7. Build the bowls

Ladle the soup into bowls. Top with a generous pile of tortilla strips, diced avocado, cheese, a spoonful of sour cream and a lime wedge on the side.

Add the toppings in that order. Strips first so they sit partly above the broth, then the avocado and cheese, then the sour cream. The cheese softens against the hot soup while the strips on top stay crisp for the first several bites.

Serve the extra strips in a bowl on the table. People always want more, and a second handful halfway through the bowl brings the crunch back.

Common mistakes and how to fix them

The soup tastes flat. A long slow cook dulls acidity. Add more lime juice, then salt, and taste again. A teaspoon of the adobo sauce also lifts the flavor.

The tortilla strips went soggy. They were added too early or were not baked long enough. Bake until they are truly crisp and add them right before eating. Serve extra on the side for refills.

The chicken is dry. Breasts were likely cooked on the thigh schedule. Check breasts at 5 hours on LOW or 2 1/2 hours on HIGH and pull them at 165°F.

The soup is too spicy. Stir in a can of drained hominy or extra corn to dilute the heat, and serve with more sour cream and avocado. Next time, use one chipotle and seed the jalapeño.

The beans fell apart. Canned beans are already cooked, so they only need to warm through. Add them in the final 30 minutes rather than at the start.

Timing and make ahead plan

Morning prep is about 15 minutes. Dice the onion and jalapeño, mince the garlic and chipotle, and open the cans. Everything except the chicken can be combined the night before and refrigerated in a lidded container.

In the morning, pour the base into the slow cooker, add the chicken and turn it on. Starting with a cold base can add about 30 minutes to the LOW time.

Tortilla strips can be baked up to 2 days ahead. Cool them completely and store in a paper bag or a loosely covered container so they do not trap moisture.

The finished soup holds on WARM for up to 2 hours. If you need it to wait longer, turn the slow cooker off, refrigerate, and reheat later. The flavor improves overnight.

For a busy weekday, set a programmable slow cooker for 7 hours on LOW before you leave. It will switch to WARM on its own, and the only work left when you get home is shredding the chicken, adding the beans and corn, and baking the strips while the soup finishes. Dinner is on the table about 30 minutes after you walk in.

Tips for the best slow cooker chicken tortilla soup

• Toast the dried spices in a small dry skillet for 60 seconds before adding them. It is a small step that makes the broth noticeably deeper.
• Use a 6 quart slow cooker. The recipe fills a 4 quart pot too close to the rim to be safe.
• Add the lime and cilantro at the very end. Cooked lime tastes bitter and cooked cilantro tastes like nothing.
• Season in two rounds. A little salt at the start seasons the chicken, and the final round is where you fine tune.
• Set out toppings in small bowls so each person can build their own. Kids who avoid spice can skip the jalapeño and load up on cheese.

Variations

• Creamy: Stir in 4 ounces of softened cream cheese or 1/2 cup of heavy cream with the beans.
• Green chile: Swap the fire roasted tomatoes for one 16 ounce jar of salsa verde and one can of plain diced tomatoes.
• Enchilada style: Replace 2 cups of the broth with a 15 ounce can of red enchilada sauce.
• Rice added: Stir in 1 cup of cooked rice with the beans for an even heartier bowl.
• Leftover rotisserie chicken: Cook the base for 4 hours on LOW, then add 3 to 4 cups of shredded cooked chicken for the final 30 minutes.

Equipment that makes this easier

A 6 quart programmable slow cooker is the workhorse. The auto switch to WARM means the chicken does not overcook if your day runs long.

An instant read thermometer takes the guesswork out of the 165°F check. A large rimmed sheet pan gives the tortilla strips room to crisp in a single layer instead of steaming in a pile.

A citrus press and a sharp chef’s knife round out the list. Fresh lime juice matters here, and a sharp knife makes even tortilla strips in seconds.

None of these are essential beyond the slow cooker itself. A regular baking sheet, a fork for shredding and a hand squeezed lime will get you to the same bowl of soup with a little more effort.

Scaling up or down

To halve the recipe, use 1 pound of chicken, one can of tomatoes, 3 cups of broth and half of everything else in a 3 or 4 quart slow cooker. Timing stays about the same.

To double it, you need an 8 quart slow cooker or two pots. Never fill a slow cooker more than two thirds full. A doubled batch takes roughly an extra hour on LOW to come up to temperature.

As written, the recipe makes about 8 servings of 1 1/2 cups each, which comfortably feeds six adults with a little left for lunch.

What to serve with it

The soup is a meal on its own, but a simple side of cilantro lime rice or a quick slaw with lime and cumin makes it feel like a spread. Warm flour tortillas with butter are always welcome.

For a soup rotation, pair it on the calendar with slow cooker white chicken chili or chipotle black bean soup. If you want a second slow cooker meal for taco night, slow cooker chicken tacos use the same toppings.

How to store, freeze and reheat

Refrigerator: Cool the soup within 2 hours and store in airtight containers for up to 4 days. Keep the toppings and tortilla strips separate.

Freezer: The soup freezes well for up to 3 months. Portion into freezer bags, lay them flat to freeze, then stack. Leave the avocado, cheese and strips out and add fresh when serving.

Reheating: Warm on the stovetop over medium heat until steaming and at least 165°F throughout. In the microwave, heat in 90 second intervals, stirring between each. Add a splash of broth if the soup has thickened.

Thaw frozen soup overnight in the refrigerator for the best texture. If you must reheat from frozen, do it low and slow on the stove with the lid on.

Leftover ideas

Thick leftover soup makes a great filling for burritos or quesadillas once you drain off some of the broth. Spoon it over rice with a fried egg on top for a fast lunch.

You can also thin it with extra broth, blend it smooth and use it as an enchilada sauce, or reduce it on the stove into a chunky topping for nachos.

Nutrition notes

One serving of soup without toppings lands roughly between 280 and 340 calories with about 25 grams of protein and 7 to 9 grams of fiber. The numbers shift with the cut of chicken and the brand of broth.

Toppings add up fast. A quarter of an avocado adds around 80 calories, a quarter cup of cheese adds about 110, and a handful of tortilla strips adds 100 to 140.

Frequently asked questions

Can I use frozen chicken in slow cooker tortilla soup?

No. Thaw the chicken fully in the refrigerator first. Frozen chicken spends too long in the unsafe temperature range before a slow cooker heats up.

How do I keep tortilla strips from getting soggy?

Bake them until they are fully crisp and add them to each bowl right before eating. Store extras in a paper bag rather than a sealed container so they stay crunchy.

Can I make chicken tortilla soup with rotisserie chicken?

Yes. Cook the broth base on LOW for 4 hours, then stir in 3 to 4 cups of shredded rotisserie chicken with the beans and corn for the last 30 minutes.

Is this soup spicy?

With one chipotle and a seeded jalapeño it has medium heat. Use two chipotles for spicy, or leave out the jalapeño and use half a chipotle for a mild version.

Can I freeze chicken tortilla soup?

Yes. It freezes well for up to 3 months. Freeze the soup on its own and add fresh tortilla strips, avocado and cheese when you serve it.

What can I use instead of chipotle peppers?

Use 1 teaspoon of chipotle chili powder, or 1 extra teaspoon of smoked paprika plus a pinch of cayenne for a similar smoky heat.
