Slow Cooker Chicken Fajitas

Bring fajitas to your slow cooker with this easy Slow Cooker Chicken Fajitas recipe! This high protein meal prep recipe is quick to make, cheap, and packed with great macros!

Start this recipe by taking out a slow cooker (this is the one I use) and optionally lining it. Lining it will save you time and make cleaning up a breeze!

Add into your slow cooker 1 can of diced tomatoes, 1 large jar of salsa, 2 teaspoons of lime juice, 1 can of drained & rinsed black beans, 2 1/2 teaspoons of minced garlic, 1 packet of low sodium fajita seasoning mix, 1/2 cup chopped red onion, 1/2 cup chopped green pepper, 1/2 cup chopped yellow pepper, 1/4 teaspoon cayenne pepper, and 3 pounds of chicken breast.

Make sure to trim the fat off of your chicken breast. I also like to cut them in half for this slow cooker chicken fajitas recipe.

Mix all of those ingredients together.

Homemade Fajita Seasoning

Make your own seasoning mix by mixing together the following ingredients:

  • 1 Tablespoon Chili Powder
  • 1 Teaspoon Ground Cumin, Black Pepper, Onion Powder
  • 1/2 Teaspoon Dried Oregano, Paprika, Garlic Powder, Salt
  • 1/4 Teaspoon Crushed Red Pepper

Pro tip? Use whatever salsa you want. Thick, chunky, restaurant style, mild, medium, hot…the choice is yours!

Cover your slow cooker and let your slow cooker chicken fajitas cook on high heat for 3-4 hours or low heat for 6-8 hours.

This step is optional but preferred. With around an hour left you can shred your chicken. To do this all you have to do is stick 2 forks into each piece of chicken and pull them apart until shredded.

This slow cooker chicken fajitas recipe tastes great as is but to step your game up even more you can use it as a tortilla filling. My favorite toppings? Cheese and sour cream or plain Greek yogurt! Let me know yours in the comments below.

    is 15 ounces the drained weight of the black beans?

      Total weight of the can (what the label says, they usually come in this size).

    I made the fajitas for my family and we all loved it. Thanks!

  3. Justin on June 5, 2015 at 12:00 am

    Yes, more meal recipes! Great again Derek.

    About time for some MEAL recipes, Derek!!! These look great. I was saying to myself I was craving fajitas & this would be a good, lower effort recipe.

    Thanks for another crockpot recipe that looks great! These are awesome. Nothing like being able to spend 10-20 min of actual prep & turn out a week or more’s worth of lunches!

    Wohoo! You’re back. Just gotta replace 40g protein with 40g carbs and this will hit my daily macros almost right on the head.
