While it’s super easy to make your own Healthy Chicken Fajitas on the stovetop or even sheet pan shrimp fajitas, this slow cooker version is even easier!

If you’ve never had fajitas before, they are basically just crockpot chicken tacos‘ veggie packed cousin. They are loaded with delicious bell peppers and onions.

These easy crockpot chicken fajitas take only 10 minutes of prep and 8 ingredients for a protein and veggie packed dinner that your family will love!

Liz’s top tips for chicken fajitas

  • Pro Tip for Shredding Chicken: Shred it in your stand mixer- it’s so much easier than shredding with 2 forks! Place cooked chicken breasts in your stand mixer and use the paddle attachment on low until the consistency you want.
  • Cut Veggies Evenly: Cut your onions and bell peppers into similar-sized strips so they cook evenly and have the perfect texture for your fajitas.

Ingredients

Substitutions

Rotel: You can substitute Rotel for canned tomatoes or diced tomatoes with green chiles.

Honey: You can replace honey with maple syrup or skip it entirely. Skip if Whole30.

Bell peppers: Any color of bell peppers will work in this recipe.

Chicken: You can also make steak fajitas by substituting the chicken with steak. We also have a Shrimp Fajitas recipe you can try, or a Chicken Fajita Casserole Recipe. If you prefer pork, try crockpot pork tacos.

Taco Seasoning: We use homemade taco seasoning. It’s way lower in sodium than the packaged kind.

WW Points: Will vary depending on the plan you follow. This is a very low/no point recipe. Olive oil will be the only high point ingredient. I’d estimate 1 point per serving.

You can also make crockpot chicken fajitas in an oven. Place in a baking dish cooked at 400 degrees for 30-45 minutes or until the chicken’s internal temperature reaches 165 degrees and the bell peppers are soft.

Can I put frozen chicken in the crockpot?

No, you can’t use frozen chicken breasts in the crock pot. This is a major food safety issue. If chicken is not entirely thawed it may not cook thoroughly. If you want to use frozen chicken to make shredded chicken, we love instant pot shredded chicken.
