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, shrimp, or pork! 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!

  • Rice: brown or white rice (seasoned)
  • Cheese: cheddar, Monterey Jack, Cotija

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).

  1. Holly, thank you. This was an easy fajita dinner and I needed that today. No mods to the recipe!5 stars

  2. I am not able to use canned foods. How many tomatoes would I need and what type of chilis do you recommend?

    1. Hi Sheri, you would need approximately 1 ½ cups of diced tomatoes for this recipe. Depending on how spicy you like your dishes you could add in some green chilies (mild) or a diced jalapeno (spicy) to taste.

  3. A total winner! Made spendwithpennies fajita seasoning and threw everything (including peppers) on sheet pan for 25-30 mins. Served with sour cream, guacamole and black beans. Will definitely make again. Thanks.5 stars

  4. Made this for a school project and ate it for lunch and dinner tots delish and i hate onions and tomatoes looks like I will be eating them for one reason only

  5. I’am retired and like to experiment with new recipes. My wife and I tried this recipe tonight and it was fantastic, much easier than doing in a frying pan.

    A couple of recommendations….”you don’t need to delay putting in the bell peppers. They need to cook the full 25 minutes. Fortunately, I caught this in advance. Also, green bell peppers taste the same as red, or yellow peppers; and they are much cheaperI

    I would recommend this recipe to all my friends and relatives.5 stars

  6. This recipe was so incredibly easy and tasty and pretty healthy. I used a fajita spice packet instead of making my own and it was delicious. It will def go into my regular rotation of week night meals.5 stars

  7. I want to eat my screen! Your fajitas look absolutely delicious. Never tried making them in the oven. Must give this recipe a go.5 stars

  8. Oh My Gosh those look delish! I can’t wait to try these. So simple and yet I’ve never thought of making them this way. Your photos are gorgeous too. Such beautiful colors. Yum yum.
