This slow cooker fajita soup makes for a comforting and healthy meal that’s packed with flavor and a hint of spice. It can be made in your slow cooker or Instant Pot!

Do you know what makes me incredibly happy? Getting done with work for the day only to realize that dinner has finished cooking and is ready to serve. That’s why I LOVE slow cooker meals!

Most have very little prep work involved – you literally put everything in, turn the slow cooker on and let it work its magic.

This recipe does require some chopping, but once everything is sliced and diced you’re ready to roll.

Fajitas… Turned Into a Soup

Overall, this recipe is pretty straight-forward. It’s basically all the ingredients you typically use for fajitas, just a bit more liquid to make it into a soup. After slow cooking for several hours the chicken gets tender, the peppers soften and the broth develops a robust, spicy flavor.

We ended up eating this soup for dinner two nights in row and like most soups it was even better the second night. Isaac mentioned how good it was several times so I have a feeling I’ll be making it again soon!

Healthy Fajita Soup Ingredients

  • vegetables – yellow, green and orange bell peppers, yellow onion, jalapeño pepper and garlic.
  • salsa – if you don’t have salsa on hand, you can make your own or just add 1 cup of chopped tomatoes, 2 Tablespoons fresh cilantro, 2 additional cloves of garlic to the soup.
  • chicken – I used boneless, skinless chicken thighs to add a bit of fat and flavor. If you prefer white meat, feel free to use chicken breasts. You may just want to add an extra teaspoon of olive oil.
  • chicken or vegetable broth
  • olive oil
  • lime Juice
  • seasonings and spices – chili powder, cumin, paprika, sea salt and ground pepper
  • toppings of choice – chopped avocado, jalapeño slices, cilantro, more lime juice, tortilla chips or crackers

Fajita Soup Variations

  • Vegan – Make this soup vegan by using vegetable broth and 1-2 cans of rinsed and drained chickpeas in place of the chicken.
  • Add grains – Make this soup heartier by adding in cauliflower rice or cooked brown/white rice. You can stir frozen or fresh cauliflower rice or cooked white/brown rice directly to the soup once it’s done cooking and warming in the slow cooker. Stir and let warm until soup is warm throughout.
  • Less spice – If you’re not a fan of spice (or serving kiddos) simply leave the jalapeño pepper out. The soup has plenty of other spices to make it flavorful.

How to Make This Soup in the Instant Pot

This soup originated as a slow cooker recipe, but we recently got an Instant Pot (air fryer combo!!) and we’re obsessed! Here’s how to make this soup in the Instant Pot:

Sauté onion and garlic – Start by adding olive oil to the Instant Pot and put it on sauté setting. Add the onion and garlic and sauté until fragrant.

Pressure cook – Add the remaining ingredients (besides the rice and toppings) to the Instant Pot. Place the lid on the pressure cooker, lock lid and make sure the pressure release valve is closed. Press cancel to stop sautéing and then press the soup/stew button and set the time to 30 minutes.

Quick release – Once the timer reaches 0, the cooker will switch to “keep warm”. Carefully switch the pressure release valve to open to quick release the pressure. Be super careful during this! I recommend using a towel over the valve or use tongs so you don’t burn yourself with the steam.

Shred chicken – Once the steam is released, remove the lid and use a fork to shred the chicken.

Add rice and serve – If you’re adding rice to the soup, add it to the Instant Pot while it’s still set to warm. Once warmed through, portion the soup into bowls, top with toppings of choice and enjoy!

What to Serve with Fajita Soup

This fajita soup is a little brothy, which I like, but it’s nice to have something (like bread, crackers or chips) to dip or crumble in. I have served it up with homemade bread, my almond flour crackers and/or tortilla chips. All of which are delicious.

Chicken Fajita Soup

Whip up this slow cooker chicken fajita soup for a comforting and healthy meal that’s packed with flavor and a hint of spice.
Prep Time: 20 minutes
Cook Time: 4 hours
Total Time: 4 hours 20 minutes
Servings: 4

Ingredients  

  • 1 yellow bell pepper, chopped
  • 1 orange bell pepper, chopped
  • 1 green bell pepper, chopped
  • 1 medium yellow onion, chopped
  • 1/2 jalapeño pepper, sliced
  • 1 cup fresh salsa*
  • 2 cloves garlic, minced
  • juice of 1 lime
  • 4 cups low-sodium vegetable or chicken broth
  • 1 1/2 pound boneless skinless chicken thighs, chicken breasts work too
  • 1 teaspoon olive oil
  • 1 Tablespoon chili powder
  • 1 teaspoon cumin
  • 1 teaspoon paprika
  • 1 teaspoon sea salt
  • 1 teaspoon ground pepper
  • cauliflower rice or cooked white/brown rice, optional
  • toppings of choice: chopped avocado, jalapeño slices, cilantro, more lime juice, tortilla chips or crackers

Instructions 

Slow Cooker:

  • Put all ingredients (besides rice and toppings) into a slow cooker.
  • Cook for 3-4 hours on high or 6 hours on low. The chicken should be cooked through and will just fall apart. Once this happens turn the slow cooker to warm and enjoy whenever you’re ready. If adding rice, add it to the slow cooker while set to warm.
  • To serve, top each bowl with avocado, jalapeño slices, cilantro and serve with tortilla chips and a slice of lime.

Instant Pot / Pressure Cooker: 

  • Add olive oil to Instant Pot and put on sauté setting. Add onion and garlic and sauté for about 5 minutes, until fragrant.
  • Add remaining ingredients (besides rice and toppings). Place the lid on the pressure cooker, lock lid and make sure the pressure release valve is closed.
  • Press cancel on the pressure cooker and then press the soup/stew button and set time to 30 minutes.
  • Once the timer reaches 0, the cooker will switch to keep warm. Carefully switch the pressure release valve to open to manually release the pressure. (I use tongs for this). Once the steam is released, remove the lid and use a fork to shredded chicken. The chicken should be cooked through and will just fall apart.
  • If adding rice, add it to the Instant Pot while set to warm. Once warm throughout, portion soup into bowls.
  • To serve, top each bowl with avocado, jalapeño slices, cilantro and serve with tortilla chips and a slice of lime.

Notes

  • If you don’t have salsa on hand, you can make your own or just add 1 cup of chopped tomatoes, 2 Tablespoons fresh cilantro, 2 additional cloves of garlic to the soup.
  • To add more bulk to the soup, I like adding cauliflower rice or cooked brown/white rice. You can stir frozen or fresh cauliflower rice or cooked white/brown rice directly to the soup once it’s done cooking and warming in the slow cooker. Stir and let warm until soup is warm throughout.

  1. I lovelovelove anything Mexican, so this soup is definitely calling me name! I can practically smell my house it cooks – great recipe girl! Pinned!

  2. Haha, the slow cooker smell when you’re home all day is partly why I find it hard to get into slow cooker recipes! It’s like torture for 6-8 hours every time!

  3. I am all about my slow cooker lately. Right now I have some apples in there with red wine and spices. I went apple picking yesterday and need to figure out what to do with some of the apples!

  4. This looks amazing- love your blog!

    Question- can you use jarred salsa or is the fresh salsa best for this recipe? Just wondering as I have all of these ingredients but just not fresh salsa on hand!

    Thanks!

    1. Thanks Olivia. I bet jarred salsa would work fine! I just put fresh salsa because that’s what I used. Let me know how it turns outs!! 🙂

      1. Your wish is my command. I already have a vegetarian slow cooker recipe ready to post in the next couple weeks! We actually ate it for dinner tonight. 😛

  5. I made this last night… it was so easy and delicious! Even my (sometimes picky) teens LOVED it! I really threw everything in the Crockpot around 2pm, turned it on high and it was finished by 5:30pm… just perfect. The avocado mellowed the spiciness of the salsa I used. Thanks for posting!

  6. I’m really excited to try this, but I LOVE mushrooms and want to add them in. How much should I add and would I have to adjust the other ingredients, especially the liquid ones? If so, by how much? Thank you!!

    1. Hi Erin. I apologize for the delayed response, but I think mushrooms would be a great addition. Adding about 1 cup of mushrooms should be fine and shouldn’t alter the recipe too much. Let me know how it turns out.

    1. Hi Shelby! I haven’t tried this on the stove-top but I’m sure it will work. Add ingredients to a stock pot, let mixture boil and then simmer on medium/low until chicken is cooked and easily shreds. It shouldn’t take longer than 30-40 minutes. For extra flavor, you can sauté the pepper, onions and garlic in a little olive oil first, add the spices and then the broth, salsa and chicken. I hope this helps! Let me know if you try it. 🙂

  7. This soup is amazing! I’ve made this serval times to the T ( Execpt I use jar salsa) and I’m in love and now share your recipes with others. I put a sprinkle of shredded cheese on top to melt into the soup with fresh avocada, cilantro and a small squeeze of sour cream sometimes extra dash of lemon. Which means it isn’t dairy free anymore… but the flavor is so worth it! I love to make a double batch and jar it up as a lunch Togo during the week!
    Thank you for sharing a favorite! <3

    I love your site and the recipes and am so happy to have found you!

    Bird food is delicious, except quinoa, lol.

    I never comment, but I found this recipe, and as a result, your website, by searching for high protein soup recipes. I recently had surgery and have been having trouble keeping anything down so have been forced to eat what is a basically liquid diet and man, have I been jonesing for something tasty. I can’t eat very much, so I only made half of the recipe, and then I had to purée it (I realize that sounds gross, but it’s my life right now!), and it’s delicious. So happy to have something I can eat that is tasty and easy to make. I look forward to making it without puréeing in the future! Thank you so much.

    1. I’m so glad you found and enjoyed this recipe, Naseem!! I really appreciate you coming back to leave a comment and star rating, it means the world to me! <3

  10. I have made this recipe several times, delicious! I liked it better with jarred salsa rather than fresh, but it could just be the salsas I picked each time. I do take out the chicken and shred and put it back in. Thanks for the recipe!

    1. Yay! So glad you enjoyed this recipe, Emily. Thanks for taking the time to leave a comment. I so appreciate it!

  11. 5 stars
    Incredible flavor! This is my go to meal when I need something quick. A big factor to recipes for me is cost, and this is definitely a budget friendly meal. Leftovers heat up perfectly as well! Thanks Brittany!

  12. 5 stars
    My whole family loved this! I’ve made it twice and we ate every last bite of it. That’s saying a lot because I have kids who won’t eat a lot of vegetables. This was a wonderful option.

    1. That’s definitely a win when the kids love it!! I’m so glad this recipe was a hit with the fam, Brittany. Thanks for coming back to leave a comment and star rating. I really appreciate it. <3

    I love how easy this is!

    I skipped the chili powder and jalapeno (because we are a family of South TX sissies when it comes to spicey foods), and while the rest of the fam topped it off with flax seed tortillas chips and cheese, I settled for creamy avocado and a pinch of Himalayan pink salt.
    I have to say that I liked it the first day, but I LOVED it the second! Definitely will be making this again.

    1. Soup leftovers are the best!! I’m so glad this soup was a hit, Stacy! Thanks for coming back to leave a comment and star rating. The reviews are SO helpful for other readers, so I appreciate it.

  14. 5 stars
    This was absolutely amazing! Definitely going to become a staple when people are coming over as it is so easy to make and super tasty! Loved this so so much.

    1. Woo!! So glad you enjoyed this soup, Vanessa. Thanks for making it and for coming back to leave a comment + star rating. I really appreciate it. 🙂

  15. If I use the instant pot do I change any of the ingredient quantities? I’m mostly curious if I should reduce the chicken stock because when you pressure cook it makes so much juice already. I’ve never used the soup setting but I’m assuming it’s the same principle. Why not just use the slow cooker feature on the instant Pot?

    1. Woo!! So glad this soup was a hit. Thanks for making it and for coming back to leave a review, Ragin. I so appreciate it. 🙂

    This soup was perfect for a cool day and the easiest Monday meal prep! It was so incredibly flavorful and delicious!! I served it deconstructed to my little ones and they devoured the chicken because it was so juicy. A great, comforting meal!

  17. This looks incredible! I’m always looking for something quick and easy to throw together that’s also healthy! And if it can go in the slow cooker – mega bonus!

  18. 5 stars
    This is delicious! I made it in my Instant Pot and it was so tasty. Used chicken breast and a can of black beans. Will definitely make it again!

  19. 5 stars
    Delicious! I made double the amount of spice mix and used half to rub down the chicken thighs the night before. The broth is light yet also rich and warm with spice. My toddlers loved adding all the toppings – but it’s so good that I ate the leftovers without any toppings for lunch. Adding it to the rotation!

  20. Just made this soup for lunch today! It is SO good and SO easy! I used a rotisserie chicken from Target because I was lazy. But I highly recommend this soup, it is super tasty! (especially with the avocados on top!)

    1. So glad you loved this soup, Whitney. Nothing wrong with rotisserie chicken!! Thanks for the review. I appreciate it!

    I’m currently making this and I have a ninja foodie instead if an insta pot. It doesn’t have the soup function so I’m trying to figure out how to make it. Any thoughts?

    1. hmmm!! I’m not familiar with the Ninja Foodie, but I’m thinking you could pressure cook on high for the same amount of time. Let me know how it turns out!

  22. 5 stars
    This soup is sooo good. It’s one of my husband’s favorites. I make it in the Instant Pot so dinner is on the table in less than an hour! Such a good soup when the weather is cold. Yum.

  23. 5 stars
    Just made this and it was delicious! I made it on the stovetop instead of a slow cooker or pressure cooker. I also added some kidney beans! Great recipe!

  24. This soup is so yummy and easy to make! We made it in the Instant Pot. It had some kick and was perfect on this cold night we’re having in New England. Topped it with green onions, cilantro, cheese, tortilla chips and jalapeños. Thanks, Brittany!

    1. Woo!! Happy to hear this fajita soup was a success, Lauren. Thanks so much for trying it out and coming back to leave a review. It means so much to me!

    1. I’m so glad this recipe turned out for you, Pat! Thanks for making it and for coming back to leave a review. It means the world to me.

    We could eat this soup every week. I followed the recipe exactly and wouldn’t change anything. It made enough for a couple of days of meals. Dolloped sour cream and sprinkled some cheddar cheese on top.

    1. Yay! So glad you loved this recipe, Laurie! Thanks so much for making it and for coming back to leave a review. I really appreciate it.

    1. YUM! I am excited to hear that you are loving this recipe and that it turned out great. Thank you so much for coming back and sharing your review + star rating, I truly appreciate it!

    Very nice recipe, if a little time consuming to put together. But, the flavor was delicious. We served with crushed tortilla chips. Great comfort food!
