These Sheet Pan Chicken Fajitas are jam-packed with flavor and the perfect balance between wholesome and comfort food. You can pile on the cheese and sour cream, or skip it all together. (Or get crazy and make a yogurt sauce.)

I like to make a double batch so that I have chicken and vegetables to throw on a bowl or even a salad later in the week. (This requires two large pans because you don't want to crowd things.)

Tips

If You don’t have Southwestern Seasoning, use 1 teaspoon chili powder, ½ teaspoon each cumin, garlic powder, salt, and paprika. Fajita season or taco seasoning also work.
I use organic flour tortillas for the family, and gluten free organic corn tortillas for myself.

Variations

Cut a zucchini and yellow squash into matchsticks and toss with a tablespoon of olive oil. Sprinkle with salt. Add to the Sheet Pan Chicken Fajitas in the last five minutes of cooking.
For a little more heat, add in ½ teaspoon crushed red pepper to the marinade.
Serve with Avocado Cream or Bacon Guacamole.
Instead of serving with cheddar cheese, serve with crumbled quasi fresco or grated Monterey Jack Cheese
