This slow cooker chicken fajitas recipe only has 5 ingredients: chicken, onions, bell peppers, diced tomatoes, and fajita seasoning. Quick and tasty, you can serve this healthy (low-carb, paleo, Whole30) fajita dish with your favorite accompaniments. Instructions to make this simple fajita recipe in the Instant Pot are also included.
Ingredients For Chicken Fajitas (ONLY 5)
There are only 5 ingredients in the easy fajita recipe!
- Chicken: Boneless, skinless breasts (or thighs).
- Fajita Seasoning: My homemade fajita blend is included in the recipe box. If you have your own, feel free to use it.
- Bell Peppers: 3 large bell peppers. I used green, red, and orange so it would be colorful. 3 bell peppers of the same color works just fine.
- Onions: 1 large onion or 2 small onions. Don’t slice them too thin.
- Tomatoes: 14.5-ounce can of diced tomatoes or your favorite salsa
How To Make Chicken Fajitas In The Crock-Pot
Making chicken fajitas is very easy, especially when you use your slow cooker (Crock-Pot) or pressure cooker (Instant Pot).
- Season the chicken with salt & pepper. Add the chicken & all the other ingredients to the slow cooker. Stir to mix well.
- Cook HIGH 2-3 hours or LOW 4-6.
- Turn the Instant Pot to sauté. Once hot, add the oil, onion, and bell pepper and cook 3-5 minutes until soft.
- Season the chicken with salt & pepper. Add the seasoned chicken, diced tomatoes, and all the other seasonings to the pot. Stir to mix well. Close lid and seal valve. Set high pressure and cook 8 minutes. When cooking time is complete, quick release pressure.
Chicken Breasts or Chicken Thighs?
Normally my go-to cut of chicken when I use my slow cooker is chicken thighs. I used chicken breasts here. I prefer to use breasts in particular with fajitas. You can also make these with boneless, skinless chicken thighs. If you do, add an additional 30 minutes to an hour of cook time for the slow cooker and 1 minutes for the pressure cooker. You need to do this because dark meat takes longer to cook than white meat. Since this recipe uses chicken breasts, it’s not a recipe that can sit on the WARM setting. This will overcook the chicken and dry out the meat. When the food is done cooking, turn off the appliance.
Homemade Fajita Seasoning
In the recipe box you will find my go-to homemade fajita seasoning. If you use it (which I hop you do) then technically this is recipe is more than 5 ingredients. Hopefully you already have these spices in your pantry already. My fajita spice blend makes about 1/3 cup of seasonings. Personally, I make a big batch and keep it in my pantry.
How To Serve The Fajitas
Traditionally fajitas are served in corn or flour tortillas. I believe you should serve these fajitas according to your dietary restrictions. My go-to is lettuce wraps. Other suggestions are tortillas or over rice (regular, brown, or riced cauliflower). You can also use this as filling for burritos or even enchiladas. Popular garnishes for fajitas include cheese, guacamole, lettuce, salsa, sour cream, etc.
FAQs & Tips
- Store leftover fajitas in an air-tight container in the refrigerator for up to 4 days.
- I used a 6-quart slow cooker or Instant Pot.

Do I have to double the Ingredients for the Fajita Seasoning to make 1/3 cup of spice or does the amounts below make up for 1/3 cup as the recipe calls for? Thanks so much in advance!
Good question. You do not need to double the ingredients for the seasoning. What’s listed in the recipe box is approximately 1/3 cup. Of course, you add more or less! Enjoy!
The recipe was great, the whole family enjoyed it. However, there is no print option available. I had to copy everything into a document and then edit it and finally, print it for my recipe book so that we can enjoy this again.
1st crockpot recipe of the year. Came out great.
Sorry, but they were too soggy for me. Next time I’ll drain the tomatoes, cook halfway on high, and finish off in the air fryer for a little crisp to the veggies. OTOH, it did give me a cup or more of good chicken veggie broth that I can freeze and use for later.
If I double this recipe, would I double the time or just keep and eye on it?
No need to double the time. It may need and additional 30 – 45 min. Unfortunately I have not made this with more than 3 pounds so you may want to watch it a bit. Let me know how it turns out!
Excellent recipe! Made it tonight and we gobbled it up. Drained Rotel tomatoes and cooked up some cilantro rice to add to the tortillas, along with sour cream and salsa. Better than Chipotle! Definitely deserved a 5-star rating on my Paprika app, and will be on my monthly rotation!

I made it and it only cooked for 2 1/2 hours and it had so much liquid and the peppers were soggy. How can I avoid this from happening again.
I cooked for about 3.5 hours the second time I made them, and it took care of that! Slow cooker.

My wife made this and it came out amazing!
Does the instant pot need any added liquid for this dish?
We tried this recipe last night and everyone liked it! Do you have any idea how many calories this is per serving?

Would a can of rotel tomatoes work or do you use regular diced tomates? I plan on putting this on my menu next week and meal prepping this for the freezer as one of my freezer/crockpot meals.when I go out for surgery. Thank you for the recipe. Can’t wait to try this!!
I used regular but absolutely rotel would be okay too. Sounds great actually. Enjoy!
Do you use any water in the slow cooker??
Nope! Just the diced tomatoes with for the slow cooker version. Enjoy!
Could I add steak and do mixed fajitas
Yes! Be sure to cook the meat until the internal temp is 165 degrees.
