If your evenings ever feel like a sprint — practices to get to, homework to wrangle, everyone hungry at once — this is the dinner for you. These oven baked chicken fajitas come together in about five minutes of hands-on work, then the oven does the rest while you handle everything else life is throwing at you.

It’s a true one-pan meal: chicken, peppers, onions, and a simple homemade spice blend all go into a single baking dish, and twenty-some minutes later, dinner is done. No standing over a hot skillet, no juggling multiple pans. Just load it up, slide it in the oven, and come back to sizzling, flavorful fajitas ready to pile into warm tortillas.

A One-Pan Lifesaver for Hectic Evenings

Some nights there just isn’t time to cook a “real” dinner between sports practices, running behind on the evening routine, or simply not having the energy after a long day. This recipe was made for exactly those nights.

Because it all bakes in one dish, you can throw it together in the few minutes you do have, get it in the oven, and use that hands-off baking time to help with homework, drive to practice, or just catch your breath. When the timer goes off, dinner’s ready. No fuss, one pan to wash, everybody fed. That’s a weeknight win in my book.

Ingredient Notes

Chicken — Boneless, skinless chicken breasts, cut into strips so they cook quickly and evenly. Boneless thighs work too.

Spice blend — Chili powder, cumin, garlic powder, dried oregano, and salt make a simple homemade fajita seasoning. (A packet of fajita seasoning works in a pinch.)

Diced tomatoes with green chilies — These add moisture and a little zip. A can of Ro-Tel-style tomatoes is perfect.

Bell pepper & onion — The fajita classics. I like using half a green and half a red pepper for color.

Oil — Helps the spices coat everything and keeps it from drying out.

Tortillas — Flour or corn, warmed, for serving.

How to Make Oven Baked Chicken Fajitas

1. Prep. Preheat the oven to 400°F and grease a 13×9 baking dish.
2. Add the chicken. Place the chicken strips in the dish.
3. Make the spice mix. In a small bowl, combine the oil, chili powder, cumin, garlic powder, oregano, and salt.
4. Coat the chicken. Drizzle the spice mixture over the chicken and stir to coat.
5. Add the veggies. Add the diced tomatoes, peppers, and onions to the dish and stir to combine.
6. Bake. Bake uncovered for 20–25 minutes, until the chicken is cooked through (165°F internally) and the vegetables are tender.
7. Serve. Pile onto warm tortillas with your favorite toppings and dig in.

Tips for the Best Oven Fajitas

• Slice evenly. Cut the chicken and veggies into similar-sized strips so everything cooks at the same rate.
• Don’t overcrowd. Spread everything in an even layer so it roasts instead of steams.
• Want a little char? Pop the dish under the broiler for the last 2–3 minutes for those signature charred edges.
• Warm your tortillas. A few seconds in a dry skillet or wrapped in a damp towel in the microwave makes them soft and pliable.
• Check the chicken. It’s done at 165°F internally. A quick-read thermometer makes it foolproof.

Storage & Reheating

Refrigerator: Store leftover fajita filling in an airtight container for up to 3 days. It makes a great next-day lunch over rice or in a wrap.

Reheating: Warm in the microwave or a skillet until heated through.

Freezing: The cooked filling freezes well for up to 2 months. Cool completely, freeze, then thaw overnight and reheat.

Meal prep: Slice the chicken and veggies ahead of time and store them in the fridge so all you have to do is season and bake.
