Sheet pan fajitas are the lazy meal prepper's best friend—everything cooks together with zero babysitting. The high oven heat replicates the char of a restaurant flat-top.
Mexican cuisine is one of the most vibrant and flavor-forward traditions in the world. This recipe captures that spirit with accessible ingredients and techniques.
Ingredients
- 2 lbs chicken breast, sliced into strips
- 2 tbsp fajita seasoning (chili powder, cumin, paprika, garlic, onion powder, oregano)
- 3 bell peppers (mixed colors), sliced, and 1 large onion, sliced
- 3 cups cooked cilantro-lime rice
- 1/2 cup salsa and 1/4 cup sour cream
- 2 tbsp olive oil, lime wedges, and fresh cilantro
Instructions
- 1
Toss chicken strips with fajita seasoning and 1 tbsp olive oil.
- 2
Toss peppers and onions with remaining olive oil and a pinch of salt.
- 3
Spread on a large sheet pan in a single layer, keeping chicken and veggies in separate zones.
- 4
Roast at 425°F for 18-20 minutes until chicken is cooked and peppers are charred.
- 5
Divide among 5 containers with cilantro-lime rice; serve with salsa, sour cream, and lime wedges.

Tips & Storage
Pro Tips
Use two sheet pans if needed—overcrowding steams the food instead of roasting it.
Squeeze lime juice over the hot fajitas right out of the oven for maximum flavor.
Let the protein rest for 5-10 minutes after cooking to allow the juices to redistribute for maximum tenderness.
Season each component individually rather than seasoning at the end — this builds deeper, more complex flavor throughout.
Storage
Refrigerate for up to 5 days. One of the best-reheating meal preps.
Reheating
Microwave for 2 minutes or reheat in a skillet for crispy edges.
