Easy Chicken Fajita Soup Recipe:

I was in the mood for chicken fajitas last week, but we didn’t have any tortillas in the house so I had to compromise. Me… being my frugal self decided to create a new recipe. Basically I took my Crockpot Chicken Fajita recipe and turned it into a soup.

This soup turned out so good! I love the fact that it wasn’t very heavy so my family can eat it even during the spring or summer. But it is the perfect comfort food on those cold winter nights! This soup is a delicious Crockpot Keto Recipe.

Keto Friendly Chicken Soup:

If you are following a Keto Diet this is the perfect soup for you! This soup has all the Mexican flavors without all the carbs!

This soup is full of flavor that is high in protein and low in carbs. I love the fact that you don’t have to feel guilty eating this delicious soup.

My entire family loves this soup! Which is great because on days when I don’t want to eat low carbs, I know that I can serve this meal and everyone will enjoy it! It sure makes dinner time easier!

If you are following a Keto diet, make sure you check out all of our Keto recipes!

You will need a crock pot for this recipe.

If you are in the market for a new crockpot, this one is my favorite. I use this all the time and it’s great. My favorite feature is that you can lock the lid down.

This is awesome for when you need to take the crockpot somewhere. I often use the slow cooker to take dishes to potluck events and this feature is amazing! There are several others on sale here.

Another favorite is this programmable crock pot  for when I am am not at home all day. I love coming home to a nice meal ready and waiting!

I also like to use crock pot liners to make clean up a breeze. These are worth every penny and save a ton of time. This is especially helpful during busy weeks of school and activities. I’m all about crock pot liners.

If you are not using a crock pot liner, I recommend spraying the crock pot insert with a non stick cooking spray or rubbing it with olive oil for an easier clean up after you make this delicious soup recipe.

Ingredients to make crock pot chicken fajita soup

Ingredients:

  • Chicken breasts (mine were frozen) or chicken thighs
  • Diced Tomatoes, 14.5 oz
  • Chicken Broth (See Chicken broth substitutes)
  • Taco Seasoning (I used homemade taco seasoning)
  • Minced Garlic
  • Onion, chopped
  • Green bell pepper chopped
  • Red bell pepper chopped
The raw ingredients in a crock pot

How to make Crock Pot Chicken Fajita Soup:

Combine all the ingredients in the crockpot.

Cook on high for 3 hours or low for 6-8 hours. (We prefer to cook on low for 6-8 hours)

Shred or chop the chicken. Stir the chicken back into the crock pot to combine the flavors.

Serve with tortillas or tortilla chips.

If you like a little extra heat, add a few dashes of red pepper flakes or chili powder to this slow cooker soup.

Topping Ideas:

If you are sticking with the low carb, try topping with extra cheese and sour cream. We love to add onion to the top of the soup also. I make sure to get some extra chicken in my bowl as well!

Tortilla chips are a great addition to this soup too (if you’re not following a low carb or keto diet)! I add them to my soup when I am not eating low carb. It is so good and gives it that extra crunch! So yummy!

Also, if you are not following a low carb diet, you can easily add in some corn, black beans and pinto beans to the soup! It just adds a little extra flavor to the soup.

Once the soup is ready, add in some fresh cilantro and you are set with a delicious soup recipe!

Tips for making this Soup Recipe:

I use a small food chopper or processor to quickly and easily chop onions and green peppers. If you do not have one of these, I highly recommend them. They are such a time saver.

I usually just chop the entire vegetable and freeze what I don’t need. It’s so nice to be able to just take diced onion or bell peppers out of the freezer for my favorite recipes.

Learn how to freeze peppers and  how to freeze onions and you will save so much time in the kitchen!

Don’t have a crock pot but have an Instant Pot? We have Instant Pot Chicken Fajita Soup that is just as good and you can have dinner on the table in about 30 minutes!

How to freeze Crock Pot Chicken Fajita Soup:

You can place everything in a freezer bag and freeze. When you are ready to cook the soup just take it out of the freezer and put it in the crock pot to cook on low.

Another option is to freeze the soup after it is cooked. I like to spoon it into silicone cupcake pans and then freeze them. This is perfect for size for individual size lunches.

    I made this but couldn’t leave well enough alone I tailored it to my family. I used hamburger meat, 1 can rotel, pinto beans I had already cooked, a half block of velveeta, 1 block 8 Oz. Cream cheese,1 package taco seasoning , two tablespoons chili powder, onion powder, garlic powder, 1 tsp. Fresh garlic, one small red onion, one red pepper, one green pepper, black pepper to taste I like a lot, one pouch of cream velveeta. Hot sauce three shakes, franks red hot brand. Red pepper flakes one shake. This was delicious. I tried it my grandson loved it, hubby loved it. For toppers I used cilantro flakes, sour cream, crispy jalapeños, you get them in the salad dressing aisle of the store. Tortilla strips also on salad dressing aisle. Cheddar cheese.

    Omg. I just made this for my hubby and I. Very tasty and easy to make! We used the taco seasoning packet instead of making our own. Very good!!

  5. Carrie Barnard says:

    You can put them in frozen.

  6. Michelle says:

    I purchased frozen peppers and onions. Should I thaw these the night before I plan to cook this or is it OK to throw them in frozen? Thanks!

  7. Brenda says:

    ABSOLUTELY DELICIOUS! I followed the recipe exactly how it reads. Easy to prepare. Will definitely make again!

  8. Maria Zerafa says:

    Made the soup but added some brown rice to make it thicker. My partner is a fussy eater where soups are concerned but he licked it and came for seconds. Thank you it was a real hit. Cooked it on the stove instead of in the slow cooker.

    Great! Your article is quite good and many good comments, hope you continue to do more articles. I will follow you

  14. Jason says:

    How long do you put it in if you got 4 lbs of meat ?

  15. Carrie says:

    Yes, I would add more broth to thin down the tomato flavor. Thanks.

  16. Dian says:

    My soup looks like it has too much tomato- it’s red, not brown. I used 14 Oz can instead of 10 Oz cans. Can I just add more chicken broth? Or is there a better idea?

  17. Carrie says:

    The nutrition information has been added to the bottom of the recipe card. Thank you!

  18. Mary says:

    What is the nutrition info?? My husband is a diabetic and I really need this info!

  19. Teri says:

    Did you thaw the chicken before putting it in the crockpot?

  20. Jason says:

    What is the nutrition info ?

  21. Nancy says:

    I make this soup often, but use 4 cups of broth. Is 2 cups really correct? There isn’t much broth with only 2.

  22. Linda says:

    Please Nutritional information to your recipes. I’m prediabetic and need the information.

  23. Tara says:

    This soup is excellent. I added some spicy peppers to give it a little kick.

  24. Pam says:

    Did you put the chicken in frozen and cook for 6-8 hours on low?

  25. Jojo says:

    How would you convert this to work in an Instant Pot?

  26. Carrie says:

    Shelby – This recipe has approximately 5 net carbs and there are 8 servings in this recipe. The exact size amount will vary between each batch. Thank you!

  27. Shelby says:

    How many net carbs is in a serving and how large is a serving?

  28. Carrie says:

    Jan – Yes, that’s correct. 10 oz cans so 20 oz total. Let me know what you think of the recipe! I hope you enjoy it 🙂

  29. Jan says:

    Is it 10 oz of diced tomatoes per can, so 20 oz total?

  30. Carrie says:

    Be sure to watch for sugar in canned tomatoes! I calculated approx. 3 grams per serving with what I used. Each can of tomatoes had 6 gr of carbs. Red pepper and onions have carbs too….
