Sheet pan chicken fajitas are my answer to busy weeknights when everyone wants something tasty and comforting but no one can spare much time. This recipe brings bold Tex-Mex flavors with just a few pantry staples and a single pan to wash. Packed with tender chicken, sweet peppers, and onions, the whole meal comes together in less than forty minutes and feels like it should have taken all day. My family loves customizing their fajita wraps with favorite toppings and sometimes I double the peppers because leftovers make incredible next day lunches.
The first time I tried this sheet pan method I was impressed by the caramelized bits you get without babysitting a skillet. Now I whip it up for casual dinners and even game nights everyone builds their own fajitas and no one fusses.
Ingredients
- Boneless skinless chicken breasts or thighs: Slice into thin strips for quick cooking and juicy results. Go for organic or free range if possible for better texture.
- Bell peppers: Any color works but a mix of red yellow and green looks vibrant and tastes sweet. Pick firm peppers with glossy skin.
- Red onion: Brings mild kick and beautiful color. Select onions that feel heavy for their size with tight skins.
- Olive oil: Use extra virgin oil for a richer base and golden finish.
- Chili powder and smoked paprika: These lend warmth and vibrant color look for fresh fragrant spice blends.
- Cumin: Adds that earthy backbone whole cumin seeds ground at home bring out the flavor even more.
- Garlic powder and onion powder: Round out savory notes go for brands with minimal fillers.
- Salt and black pepper: Choose kosher salt and freshly cracked pepper for better bite.
- Fresh lime juice: Cuts through richness with zing squeeze just before serving for brightest flavor.
- Flour tortillas: Soft and pillowy pick up from a local bakery if you can.
Instructions
- Prep the Produce:
- Slice chicken breasts or thighs thinly across the grain this keeps them tender and helps them cook evenly. Core and slice peppers in long strips. Peel and slice onion into half moons.
- Mix the Seasonings:
- Combine chili powder smoked paprika cumin garlic powder onion powder salt and pepper in a small bowl. Stir well and taste a pinch to check for balance.
- Marinate the Chicken and Veggies:
- Drizzle olive oil over the chicken mixture in a large bowl. Sprinkle on the mixed spices and toss everything together thoroughly so every piece is coated. Let rest while oven heats.
- Arrange on the Sheet Pan:
- Spread chicken and veggies evenly in a single layer on a rimmed baking sheet. Crowding results in steaming rather than roasting so use two pans if needed.
- Roast Until Golden:
- Slide pan into a hot oven set to four hundred and twenty degrees Fahrenheit. Bake for about twenty to twenty five minutes until chicken is cooked through and vegetables caramelize at the edges. Stir halfway to ensure even browning.
- Finish With Lime:
- Squeeze half a lime over everything as soon as it comes out of the oven. Let flavors mingle for two to three minutes while you warm tortillas.
- Serve Hot:
- Pile the roasted chicken and peppers into warm tortillas and top with favorites like salsa chopped cilantro avocado or shredded cheese. Let everyone build their own.

Bell peppers are my personal favorite here their sweetness intensifies in the oven and contrasts beautifully with the smoky chicken. I remember my kids’ faces the first night we tossed everything on the pan and let them help chop and mix. Now they beg to be the sous chefs for fajita night.
Storage Tips
Cool leftovers to room temperature and refrigerate in airtight containers. I wrap the fajita filling in foil and portions stay juicy for up to four days. For a fast lunch just reheat in a skillet or microwave and spoon into fresh tortillas.
Ingredient Substitutions
Swap in portobello mushrooms or sliced zucchini for a vegetarian version. If you are out of chili powder try Cajun seasoning or taco spice mix in equal measure. Corn tortillas work just as well as flour and add classic flavor.
Serving Suggestions
Serve the fajitas with Mexican rice simple black beans or a quick tomato salsa. Set out toppings like sour cream grated cheese diced avocado and pickled jalapeños for everyone to personalize their wraps.
