Is Fajita Friday a thing? If not I think we should make it one. Cause Taco Tuesday has NOTHING on these Whole30 Chicken Fajitas.
Even if you’re not doing a Whole30 this is a delicious chicken fajitas recipe that regardless of your diet anyone will love!

When I was on a Whole30 – I was okay with letting go of some of my favorite things for a few weeks..(pasta, bread, cheese, etc) but one thing I was NOT going to give up was Mexican food.
No joke – we eat Mexican food (usually tacos) at least once weekly. We keep it pretty simple with a whole wheat tortilla, ground turkey, guac, cheddar cheese, salsa, and our own healthy taco seasoning.
I knew I could make a simple Whole30 Fajitas recipe that would be delicious and satisfy my cravings!

How to make Fajitas Paleo/Whole30
- Swap tortillas for lettuce wraps– Traditional fajitas are served with tortillas which aren’t paleo or whole30. I like to use romaine, butter lettuce, or even iceberg for our lettuce wraps.
- Find Whole30 approved salsas to top your fajitas so you don’t miss the cheese and beans– This Pineapple Mango Salsa is a great topping to tacos or fajitas. So is guacamole! Both are so full of flavor you won’t even miss the cheese!
- Load up on spices! Great spices can make anything taste good! This Whole30 fajita seasoning recipe is easy and made with spices you likely have in your pantry. I blended a mix of my favorite spices to create the perfect flavor packed dish. When the spices mix with the moisture of the veggies you have this yummy paleo/whole30 fajita sauce that is DELICIOUS!
Healthy Fajita Recipe Substitutions and Additions
Chicken Breasts: You can substitute with boneless chicken thighs or chicken tenders.
Veggies: Add more or less vegetables to this recipe. Mushrooms are also a great addition. If you’re looking for vegetarian fajitas – check out these Fajita Veggies!
Olive Oil: You can substitute avocado oil, butter, or ghee.
Spices: We love using the spices as written in the recipe or our Healthy Taco Seasoning, but you could use a premade taco seasoning. It would just increase the sodium content.
Can this Healthy Fajitas recipe be made in the crockpot?
Yes, you can! We’ve included crockpot instructions below for you in the recipe. We also love this crock pot chicken fajita recipe!
Can you make these fajitas with steak or shrimp?
Steak and shrimp tend to cook differently than chicken. I’d recommend checking out these recipes if you’re looking to sub out the chicken: Whole30 Steak Fajitas, Whole 30 Shrimp Fajitas, or Sheet Pan Shrimp Fajitas.

Can you make this healthy fajitas recipe vegetarian?`
Yes! You can double up on the vegetables in this recipe and skip the chicken or make these Fajita Veggies!

I am SO excited to try this recipe. Currently doing Whole30 and need some new recipes. When doing this in the crockpot, would you put everything in at the same time and cook for 6 hours or cook the chicken first then add everything else to crockpot?
The Clean Eating Couple says
Hi Karen! hope you love it. I just adjusted the instructions in the recipe card to make them more clear. Brown the chicken first, then add everything in. Hope this helps! -Liz
