Easy Chicken Fajitas Chicken Fajita Recipe

Chicken fajitas are one of our go to weeknight meals because they’re easy to make in just thirty minutes and they’re a good way of getting kids to eat a lot of vegetables. We also like to mix the recipe up and serve it with non traditional options for a more Tex-Mex feel (like with Queso dip – this combination is amazing).

In addition to this recipe working well with chicken breasts, you can also use lean steak, pork loin or any seafood you’d like. The fajita seasoning and the vegetables work great with all proteins, my favorite being shrimp fajitas.

The best way to cook chicken fajitas is on high heat in a grill pan like or a griddle. The higher the heat the better the sear on the chicken and the vegetables since we’re cooking them for only a few minutes. If you’d prefer to use a pan for a stir-fry style I recommend using a cast iron pan as it will give the best sear and flavors.

Since we’re cooking it quickly you can also substitute skinless chicken breasts for the chicken thighs that are in the recipe, but you’ll have to serve them quickly as they will dry out faster than chicken thighs which can sit in a hot griddle through serving with no issues.

The chicken fajitas can also be grilled, put in a slow cooker or cooked on a sheet pan because the recipe is totally adaptable. If going in the slow cooker use , if being grilled cook over medium high heat and cook the veggie portion in a grill basket.

Grilled Chicken Fajitas

Add all the ingredients tossed in olive oil and the seasonings to a grill basket and cook on on medium high heat for 8-10 minutes until the chicken is cooked and the vegetables are just starting to char.

Slow Cooker Chicken Fajitas

Add the chicken and seasonings to the slow cooker (do not pre-slice the chicken) and cook the chicken for 4 hours on low heat. Slice the chicken, toss with the vegetables and additional seasonings and cook on low an additional two hours. You’d end up with great flavors if you seared it off in a pan before serving but I get that it defeats the purpose of the slow cooker.

Sheet Pan Chicken Fajitas

If cooking on a sheet pan line everything up in as even a layer as possible and roast at 400 degrees for 18-20 minutes. If you crowd the pan too much the food will steam instead of brown at all and it will taste boiled.

I promise you, these are the best chicken fajitas whether you grill them, slow cook them or bake them off on a sheet pan. First time you make them, make them in a large skillet as written below and the next time you make them try them on the grill. With summer coming, this recipe is perfect for grilling.

Plus if you’re like me, any recipes with a short cook time are a winner when the weather starts warming up!

Favorite Toppings and Mexican Food Sides:

  • Marinade: We don’t marinate the meat in the recipe but if you did add a marinade or even just added the seasonings to the chicken the night before.
  • Fresh lime juice: this adds a freshness and brightness to the dish along with a ton of flavor.
  • Sour Cream: adds a creamy, cool element the recipe.
  • Guacamole: adds richness and creaminess to the dish and enough flavor to avoid other fats.
  • Cilantro: It isn’t just a garnish, adding chopped cilantro adds a lot of great flavors.
  • Salsa (Pico de Gallo): Fresh salsa is a healthy way to add a lot of extra flavor.
  • Refried Beans: Homemade refried beans are great for binding a fajita wrap or as a side.
  • Queso: Perfect as a topping/sauce or for a side dish with chips.
  • Mexican Rice: The ultimate easy side dish for all Mexican food.


  • With flour tortillas or corn tortillas as originally intended.
  • In hard taco shells topped with lettuce and tomato or even a creamy slaw.
  • With a large salad full of romaine, grape tomatoes, avocados, salsa, and sour cream.
  • In a rice bowl, or over cauliflower rice for a low carb option.
  • Rolled in a warm tortilla with sharp cheddar cheese, sour cream and baked with enchilada sauce.
  • In lettuce cups instead of tortillas.
  • Chopped up leftovers stuffed inside of quesadillas for a perfect, easy leftovers meal.

  1. Hi Sabrina. Making the sheet pan version of this tonight. Do you recommend leaving the thighs whole and cutting into strips after roasting, as in the stove top method? Or is it better to cut into strips and then roast? Thanks!

  2. This was sooo delicious!! This dish never made it to the table……my husband and I stood at the stove, filled our tortillas and gobbled this down like we had not eaten in days.

  3. These fajitas were absolutely fabulous! I highly recommend doing a brine to them for about 15 minutes before you start. It lets all those seasonings soak into the chicken…so good! Thank you for sharing!

    1. So glad you liked them! And yes, if people have the time, the brine is definitely recommended! Thanks for the review!

  4. I love this site and and my family loved these fajitas. Only change was to cut the chicken into slices before adding the seasonings and then cooking in the oil. DELICIOUS!

  5. I made this tonight. Just fantastic. I had to stop myself at 3. I told my wife I could finish the pan. Your web site has been a huge blessing to my family. Thank you.
