Oven Fajitas are a delicious and fresh meal that is easy to prep and loaded with flavor. Chicken, onions, and bell peppers are seasoned with a simple spice mixture and cooked in the oven until the peppers are tender-crisp.

These are perfect piled high in a tortilla and topped with your favorite toppings. Serve with a helping of cilantro lime rice and topped with our favorite Pico de Gallo for a delicious meal!

Why Make Fajitas in the Oven?

Chicken Fajitas is one of my all-time favorite meals! I should say ANY fajitas including steak or shrimp! Oven chicken fajitas are tender when and so flavorful as the veggies are added and everything cooks together all in one dish!

So just toss the ingredients together, pop in the oven and walk away for an easy, quick, and mess-free dish!

How to Make Oven Fajitas

This recipe starts with sliced onion, chicken, seasonings, and tomatoes.  I find that slicing chicken while it’s partially defrosted makes the job much easier!

  1. Mix together all ingredients per the recipe below (except peppers) in a casserole dish.
  2. Place casserole dish in the oven and bake about 15 minutes. Add the bell peppers and bake another 10 minutes.
  3. Heat the tortillas (corn or flour) per package directions and fill as desired!

Once done, a quick squeeze of fresh lime (and a sprinkle of cilantro) makes these fajitas pop with flavor!

Got Leftovers?

If you’re lucky enough to have any leftovers, they make amazing quesadillas the next day for lunch or are perfect on a salad with a dressing of salsa and sour cream (or greek yogurt).
