How to make Easy Oven Chicken Fajitas: the recipe for a sheet pan of flavorful, juicy fajitas.
The main issue when making sheet pan fajitas is achieving even cooking of chicken and vegetables.
Often the chicken dries out while the peppers remain raw, or vice versa, or everything ends up stewing in its juices instead of searing and caramelizing.
Another common mistake is lack of flavor, if the spices don’t penetrate well or the meat isn’t allowed to rest long enough to absorb the seasoning.
The secret to solving these problems is a short marinade and a two-step oven cook: the first high-temperature phase cooks the chicken and softens the vegetables, while a brief final broil/grill phase creates that delicious crust.
Using a homemade seasoning intensifies the flavor, and uniformly cutting the ingredients ensures perfect cooking for all.

How to Make Easy Oven Chicken Fajitas
Place a rack in the upper part of the oven and preheat to 428 °F. In a small bowl, mix well the chili powder, cumin, paprika, garlic powder, onion powder, salt and pepper.
On a rimmed baking sheet, distribute the chicken strips, sliced peppers and onion slices evenly.
Drizzle with a little olive oil and sprinkle with the prepared spice mix. Toss everything directly on the sheet to evenly coat each piece.
Let rest at room temperature for at least 10 minutes (or up to 2 hours in the refrigerator for a more intense flavor).
Bake the sheet for 18-20 minutes. Then switch to the grill (or broiler) mode for another 2-3 minutes, or until the edges of the vegetables are golden and slightly charred and the chicken has reached an internal temperature of 165 °F.
During the last 5 minutes of cooking, wrap the tortillas in foil and place them in the oven with the fajitas to warm them.
Once the fajitas are ready, squeeze fresh lime juice over them and sprinkle with chopped fresh cilantro if desired. Serve immediately with warm tortillas and all your favorite toppings on the side, creating a true fajita “bar”!
Ingredients Notes & Substitutions
Chicken: You can use pre-cut chicken pieces or boneless, skinless thighs cut into strips. There’s no need to pound them.
Vegetables: If you don’t like bell peppers, you can substitute sliced mushrooms, zucchini sticks or finely chopped broccoli. The important thing is that the cuts are uniform.
Fajita seasoning: If you’re in a hurry, you can use 2 1/2 tablespoons of store-bought fajita seasoning, but homemade is more flavorful and additive-free.
Storage
Refrigerator: Cooked fajitas keep in an airtight container in the refrigerator for up to 4 days.
Freezing: You can freeze cooked leftovers for up to 3 months. Thaw them in the refrigerator overnight before reheating.
Make-ahead (raw): Toss raw vegetables and chicken with the seasoning, put them in a zip-top freezer bag and freeze for up to 3 months. Thaw in the refrigerator overnight before cooking as directed.
Reheating: Reheat in a skillet over medium heat, in the oven, or in an air fryer at 347 °F, or in the microwave in 30-second intervals until hot throughout.
Recipe Variations
Shrimp Fajitas: Substitute the chicken with peeled shrimp. Cooking times will be shorter (about 10-12 minutes plus the broil).
Vegetarian Fajitas: Add black beans or canned corn (drained) to the sheet pan along with the other vegetables to make it a complete vegetarian dish.
Tips
Uniform cuts: This is the secret to even cooking. Make sure the chicken, peppers and onions are about 3/8 in thick.
Don’t overcrowd the pan: If you’re making large quantities, divide the ingredients across two pans. If the sheet is too full, the ingredients will steam instead of sear.
Warm the tortillas: A warm tortilla is essential for an authentic fajita experience.
FAQ (Questions & Answers)
Can I use other cuts of chicken?
Yes, boneless skinless thighs are a great alternative and remain even juicier.
Can I make this recipe without an oven?
Yes, you can cook them in a very large skillet over high heat, adding the ingredients in batches so you don’t lower the pan temperature and so they brown well. The result will still be excellent!
Can I marinate longer?
You can marinate the chicken and vegetables for up to 2 hours in the refrigerator for a more intense flavor, but it’s not strictly necessary.
