One-Pan Baked Chicken Fajitas making your dinner prep easy, quick, and delicious!
My dad asked for a low-key birthday this year—no restaurant, no fuss. I wanted to make something quick, flavorful, and with minimal cleanup so he wouldn’t have to do the dishes. A sheet-pan dinner felt perfect.
I had extra peppers from a recent Mexican quinoa salad and some chicken thawing, so I turned it into a simple fajita-style meal. It’s great served over rice or leftovers from the salad, and the flavors deepen if it sits a bit before serving.
This one-pan dinner is effortless and wonderfully tasty. All you need is chicken, mixed peppers, a red onion, a few pantry spices, and olive oil.

Notes
- Bake the Veggies First: Roast the peppers and onion alone for about 8 minutes before adding the chicken. This helps everything finish evenly without undercooked or overcooked pieces.
- Coat the Chicken Evenly: Toss the chicken strips with the spices in a bowl until each piece is well covered so the seasoning is distributed evenly.
- Use a Variety of Peppers: Red, green, orange, and yellow peppers offer different flavors and colors; using a mix makes the pan vibrant and tasty.
