HOW TO MAKE SHEET PAN CHICKEN FAJITAS:

Preheat oven to 425 degrees Fahrenheit. In a small bowl, mix together seasonings: paprika, chili powder, garlic powder, onion powder, cumin, and sea salt. Set bowl aside.

STEP 2: SLICE PEPPERS & ONIONS

Grab a cutting board and a sharp knife. Slice bell peppers into 1 inch strips, see how to cut one below ▼, and slice onion into 1/2 inch strips. Place on sheet pan. You do not need to oil or cover your sheet pan with foil or parchment paper.

STEP 3: SLICE CHICKEN BREAST

Slice chicken breast into 1 inch strips. Watch this video on how to slice chicken into strips for fajitas. When sliced, place on sheet pan.

STEP 4: TOSS

Drizzle oil onto the fajita mixture and toss. Sprinkle half of the seasoning mixture. Toss fajitas with tongs or your hands to evenly distribute seasoning. Sprinkle the other half of seasoning onto sheet pan and toss once more.

Serve immediately or warm with grain free tortillas, in a salad with mixed greens, with a side of gluten-free white rice or by itself topped with guacamole.

HOW TO CUT A BELL PEPPER FOR FAJITAS

There are many ways to cut a bell pepper. This method is specifically for fajitas.

HOW TO REHEAT FAJITAS

To reheat fajitas, place them in a skillet on low heat with a little oil. You can also microwave the fajitas, but be cautious of the time so that you don’t overcook the chicken.

PREP FAJITAS AHEAD OF TIME

To prep this recipe ahead of time, cut the bell peppers, onions and chicken. Place the mixture in an air-tight glass container or zip lock bag. Keep in the fridge for up to 1 day. When you are ready to bake the fajitas, place them on the sheet pan and toss with oil and fajita seasoning.

TIPS AND VARIATIONS:

  • Serve fajitas with guacamole, pico de gallo, grain free tortillas, mixed greens, white rice, cauliflower rice, salsa, or other grilled vegetables.
  • Some good toppings for fajitas are: sliced avocado, guacamole, cilantro, limes or pico de galo.
  • Watch your oven time to make sure you don’t overcook the chicken. Chicken should be golden brown and at 165 degrees Fahrenheit when fully cooked.
  • Use different meats such as steak, or beef. Rump, skirt, or flank steak are said to be the best cuts for fajitas.
  • Buy grain free tortillas that are made with cassava flour or almond flour. Stay away from those that are made out of corn, flour, or whole-grain tortillas. These are filled with processed ingredients. Check the ingredients before you buy!

Enjoy, friends!
