Simple Soup Recipe Full of Southwest Flavors 

This delicious soup will fill your home with wonderful, savory scents while it cooks!

All of the things we love about fajitas and tortilla soup come together in this savory recipe. Chicken and bell pepper strips are slow-cooked with onions and garlic in a mildly zesty and savory chicken broth. We add just a little bit of paprika and cayenne pepper at the beginning of the cooking process to infuse the broth with their flavor. If you are serving kids or anyone sensitive to spice, feel free to skip the cayenne. 

Note that you can make this soup more hearty by adding frozen corn kernels and/or drained and rinsed black beans at the beginning of cook time. After you’ve added all of the ingredients to the Crock-Pot, simply turn it on high for three to four hours, or low for five to six hours and go about your day!

Want to Make Your Own Tortilla Strips?

If you have a few extra minutes, we highly recommend making your own crunchy tortilla strips to use as a yummy topping! They’re super easy and will add an incredible crunch to your soup!

You can make the strips using whole wheat or corn tortillas. Preheat the oven to 350 degrees Fahrenheit while you’re slicing the tortillas. Place the strips on a nonstick baking sheet and lightly coat in olive oil cooking spray. Sprinkle on a little bit of salt and pepper and place the pan in the oven for approximately 20 minutes, or until the strips are a beautiful golden brown!

Bring on the Toppings

This tasty chicken soup is made with healthy ingredients you can feel good about!

Once your soup is ready, adding a squeeze of lime juice to the finished dish adds just the right amount of acidity and freshness. 

Topping this soup with fresh cilantro, a dollop of sour cream or plain Greek yogurt, creamy avocado slices, and crunchy tortilla strips makes it extra yummy! You can also add some shredded reduced-fat cheese, such as mild Cheddar or Colby jack, as well.

    1. Sara, Chicken can be added uncooked on top of the vegetables in the slow cooker. That said, you can brown the chicken first by searing it in a little oil on the stovetop over high heat for a minute or two (get the pan with oil hot before adding the chicken), just to get the outside golden. If you do decide to do that step, you don't have to cook all the way through.

  1. This soup is outstanding! It’s super easy and super good! So good, in fact, that the kids and grandkids want to come over for dinner when I mention I’m making it. That’s it’s healthy, too, is a great benefit!

  2. I just made this soup today, followed all directions and use all ingredients. But the broth isn’t clear, really strange looking. I don’t know what happened. Do you have any idea

    1. Kathleen, If the taste is good then the color doesn’t matter all that much. We’ll soon be adding updated photos…be on the look out. 🙂

  3. Back when my parents would diet, we would have to eat what mom made. It was usually plain white rice, unseasoned chicken or fish and some level of unseasoned veggie (usually green beans). Every. Night. First, it’s no wonder their diet didn’t last cause…bland and repetitive. But then that made me grow up thinking that those bland meals were what dieting was. So when I started to gain weight and diet I thought I’d have to suffer with bland meals every day, not very motivating. Then when I saw diet recipes online, the ones I saw were labor intensive and not very appealing. Finally now we have things like this where we can take a few ingredients, fast and simple and they look amazing. I can’t wait to try!

  4. I woke up this morning to a broken freezer with quickly thawing food. I had just happened upon this recipe and since the chicken thighs, stock and corn had thawed, it quickly became crock pot tortilla soup. Okra and green beans thawed, into the soup. Just because I like tofu I threw that in. I used more cumin, pepper and garlic because I like spicy. The cilantro and lime juice really kick it up a notch. Delicious.
