Substitutions & Variations
- Bell Peppers to Use: We really love using red, orange, or yellow bell peppers in our fajitas because they’re naturally sweeter, a little more tender, and bring the best flavor. I’m personally not a fan of green bell peppers because they’re more bitter and a bit sharper in taste. But if you love them, go for it! Use what you enjoy. This recipe is super flexible and works with any mix you like!
- Fajita Seasoning Options: You can use one package of your favorite fajita or taco seasoning in this recipe. Or, try our easy and delicious chicken taco seasoning, or make the fajita seasoning we made for this recipe. Any of these options works well!
- Chili Powder: I’ve made these fajitas so many different ways, and I love ancho chili powder for its mild heat and rich, slightly sweet depth. Regular chili powder is an easy swap and gives a more classic, slightly tangy flavor with less sweetness and depth, but still tastes delicious. Or, for smoky heat, try chipotle chili powder. If using chipotle chili powder, start with half the amount and adjust as needed, since it’s more intense.
- Chicken to Use: Boneless, skinless chicken breasts keep this recipe leaner. For a juicier option, you can use boneless, skinless chicken thighs instead. Just keep in mind, chicken thighs may need a couple of extra minutes. Ensure they are fully cooked before serving.
How To Make Healthy Sheet Pan Chicken Fajitas
- Use a packet of store-bought fajita seasoning or make our homemade version. In a small bowl, thoroughly mix the chili powder, smoked paprika, garlic powder, onion powder, cumin, oregano, salt, and pepper.
- Slice the chicken breasts into thin, even strips, about 1/2-inch thick, so they cook quickly and evenly. To keep the chicken tender, slice against the grain.
- Slice the bell peppers and onion into even strips.
- Add the sliced bell peppers, onions, and chicken to a sheet pan lined with parchment paper. Lightly spray with olive oil spray.
- Sprinkle the fajita seasoning evenly over everything. Then toss everything directly on the pan until well-coated.
- Bake at 400°F for 20-25 minutes, or until the chicken is fully cooked through and reaches an internal temperature of 165°F. Once done, let it cool slightly, then serve and enjoy.
Expert Tips
- Even Slicing: Slice the chicken, bell peppers, and onion evenly so everything cooks at the same rate. Keep chicken strips and veggies similar in thickness so nothing overcooks or undercooks.
- Season Well: Give everything a good toss on the sheet pan before baking, so the seasoning is evenly distributed.
- Cook Just Right: Make sure the chicken is fully cooked through and reaches an internal temperature of 165°F, but avoid overcooking so it stays juicy and tender.
- Don’t Overcrowd: Toss everything well on the sheet pan, but leave enough space so it roasts instead of steaming. Spread everything in a single layer on the sheet pan.
Serving Suggestions
Serve these sheet pan chicken fajitas on their own, or use your favorite corn or flour tortillas to make tacos. You can also make lettuce wraps or a bowl with cilantro lime cauliflower rice or Spanish cauliflower rice. Top with our healthy guacamole with Greek yogurt, protein guacamole with cottage cheese, easy homemade Pico de Gallo, cottage cheese queso, or a drizzle of our healthy avocado crema. Finish with a squeeze of lime and cotija cheese if desired.
Storage Instructions
Store leftover chicken fajitas in an airtight container in the refrigerator for 2-3 days.
Sheet Pan Chicken Fajitas FAQs
How to Cut Chicken for Sheet Pan Fajitas?
Slice boneless, skinless chicken breasts into thin, even strips. Slice the chicken against the grain, cutting across the direction the muscle fibers run rather than with them, to keep the chicken tender and juicy.
Do You Cover Sheet Pan Fajitas?
No, bake uncovered so the vegetables and chicken roast properly. Leaving them uncovered helps everything caramelize slightly instead of steaming.
How Long to Bake Sheet Pan Chicken Fajitas?
Bake sheet pan chicken fajitas in the oven at 400°F for 20-25 minutes, or until the chicken is fully cooked through and reaches an internal temperature of 165°F. The exact cooking time will depend on the thickness of the chicken strips. Also, make sure the bell peppers and onions are tender.
