Baked Chicken Fajitas

These quick and easy Baked Chicken Fajitas are packed with veggies, all cooked in one pan, and ready in 30 minutes!

They are also clean-eating, low-carb, gluten-free, and Whole30-friendly. Serve them with some Crockpot Pinto Beans or Mexican Cauliflower Rice for a quick, healthy meal.

I love fajitas in almost any form, but when I don't have time to cook them on the stovetop, I make this simple oven-baked version. It’s not only easy but the fajita chicken and vegetables have a ton of flavor.

Although it’s an easy meal and takes a little longer, there isn’t as much active cooking time, so I can get all sorts of things done in the kitchen while they cook.

Truthfully, to make it even easier, I usually pick up pre-sliced vegetables at the salad bar, so all I have to do is make the fajita seasoning mix and toss everything in a pan.

It couldn't be easier, and we seriously love this sheet-pan chicken fajitas recipe—maybe even more than the traditional version. It’s also so good with salmon, like in these easy salmon fajitas.

Additionally, these baked chicken fajitas are perfect for meal prep if you like to prepare meals to whip out on a busy weeknight.

They taste even better the next day since the flavors have time to combine and deepen in the fridge. Then you can enjoy chicken fajitas for lunch or dinner during the week.

Serve them traditionally with warm tortillas, salsa, cheese, and avocado. Try them in a low-carb wrap with your favorite cheese for a quick quesadilla. Build a delicious chicken fajita bowl with rice, cauliflower rice, or greens.

Ingredients for Baked Chicken Fajitas

Here’s what you need to make one-pan chicken fajitas in the oven. You can find the specific measurements from the recipe card at the bottom.

• Chicken: When it comes to making these baked chicken fajitas, I always go for boneless, skinless chicken breasts. They're lean, healthy, and soak up that fajita seasoning like a dream. You'll want to slice them thin so they cook evenly and absorb all those amazing flavors.
• Tomatoes: They add a juicy burst of freshness that balances the savory spices perfectly. For this recipe I use canned diced tomatoes with green chiles. They break down just enough in the oven to mingle with the other ingredients, creating a delicious sauce.
• Onions: Onions add a sweet depth of flavor that complements the spices beautifully. I like to use red onions for a bit of sweetness, but you can also use a white or yellow onion if you prefer. I usually slice my onions thin so they caramelize slightly in the oven, adding layers of flavor to the dish.
• Bell Peppers: I toss in a mix of red and green bell peppers, sliced into strips. Feel free to also add yellow or orange bell peppers. They not only make the dish look incredibly appetizing but also add a slightly sweet and earthy taste that ties everything together.
• Mushrooms: Mushrooms might not be traditional in fajitas, but trust me on this one—they're a fantastic addition! I use sliced button or cremini mushrooms for their meaty texture and ability to soak up flavors like little sponges.
• Fajita Seasoning: The heart and soul of any fajita recipe! I whip up my own blend with chili powder, paprika, cumin, garlic powder, onion powder, oregano, and sea salt. This homemade fajita seasoning mix ensures each bite is packed with bold, smoky flavors that will have everyone asking for seconds.

Plus, don’t forget your favorite toppings for fajitas!

How to make homemade fajita seasoning?

Fajita seasoning is super easy to make at home with spices you likely already have in your spice cabinet. Plus making it at home means you get to control the level of spice and stay away from fillers and preservatives.

Here's an easy recipe that will keep in your pantry for up to 1 year in an airtight container.

• 4 tbsp chili powder
• 2 tbsp paprika
• 4 tsp ground cumin
• 4 tsp garlic powder
• 4 tsp onion powder
• 2 tsp dried oregano
• 2 tsp kosher salt

Depending on how you will be using it, some people like to add 1-2 tablespoons of cornstarch to help the sauce thicken when cooked.

Also, if you like a touch of sweetness in your fajita seasoning, you can add 1-2 teaspoons of sugar.

Can you use taco seasoning to make fajitas?

Absolutely! However, it will change the flavor of this chicken fajita recipe slightly.

Taco seasoning tends to be spicier and has more chili powder than fajita seasoning does. Fajita seasoning is usually slightly milder with more garlic and onion flavors, opposed to the spicy and smoky flavors in taco seasoning.

If you decide to swap in taco seasoning, you can use store-bought or homemade taco seasoning. You will have around two tablespoons of seasoning for 4 servings.

How to Make Baked Chicken Fajitas

Making chicken fajitas in the oven is really easy. Here’s how you do it:

1. Slice up the Fajita Vegetables

Start by slicing the bell peppers and onions into thin strips. Aim for uniformity here—it's key for even cooking. Next, slice the mushrooms and then combine with the peppers and onions.

2. Prepare the Chicken Breasts

Using a sharp knife, cut the boneless, skinless chicken breasts. You'll want to slice these into strips too, keeping them the same size for consistency. This ensures every piece is just as juicy and tender as the next.

3. Make the Fajita Seasoning

Combine the chili powder, paprika, cumin, garlic powder, onion powder, oregano, and sea salt in a small bowl. Give it a good whisk until everything's blended perfectly. This spice mix is going to bring your fajitas to life!

4.Toss it All Together

Put the sliced bell peppers, onions, mushrooms, and canned tomatoes (juice and all) and lay them in a greased baking dish. Next, add the chicken strips on top. Sprinkle the fajita seasoning evenly over the fajita mixture and now, get your hands in there and mix it all up—don't be shy! Your hands are the best tools you have to ensure everything is coated beautifully.

5. Bake in Oven

Slide your baking dish into a preheated oven and let it bake for 25-30 minutes. What we're looking for is chicken that's thoroughly cooked and veggies that are tender yet crisp.

In my world, it's not really a chicken fajita without some amazing toppings. Here are the things you will always find on our table.

• Shredded cheese: my favorite is an extra sharp cheddar or a more traditional Monterey Jack cheese. Some of my family like to use pepper jack cheese - so choose what you like best.
• Cilantro: add some brightness and freshness to the dish
• Limes: another way to add some zest and freshness
• Sour cream or Greek yogurt: a great way to add some tang and cool down the spices
• Avocado or guacamole: another great way to cool down the spices and add some creaminess
• Salsa: it's always a good idea to have some extra salsa for anyone who wants some extra heat
• Lettuce: this one is a bit controversial but sometimes people like to serve some shredded iceberg lettuce on the side

Recipe Ideas and Tips

There are lots of ways to customize this recipe and make it your own. Here are some of our favorites.

• Add some fiber: Adding a can of drained black beans or pinto beans to your baked fajitas will add in extra fiber. Personally, when I add beans to this recipe I prefer black beans.
• Bring a pop of color: For some extra color, throw in some canned or frozen corn.
• Spice it up: For some extra spice, use Rotel tomatoes or any canned diced tomatoes with habaneros. For less spice, swap in normal diced tomatoes. Speaking of the tomatoes, you could also use store-bought salsa or pico de gallo for a different spin.
• Top with cheese: Sprinkle a layer of cheese on top during the last five minutes of cooking for a cheesy top layer.
• Use chicken thighs instead: Swap in chicken thighs for chicken breast if you prefer dark meat chicken.
• Make it a bowl: Instead of serving this in the traditional manner with flour tortillas, serve it over some cooked rice, quinoa, or cauliflower rice.

Meal Prep for Baked Chicken Fajitas

This is a great recipe to prepare on the weekend and have packed and ready to go for lunches. It's easy to prepare and keeps well in the fridge.

However, since it can get boring to eat the same thing every day, here are some ways to mix things up.

1. Start traditional and pack the fajitas up with some flour tortillas and shredded cheese for day one.
2. On the second day, serve the chicken fajitas over a bed of black beans and brown rice.
3. For day three, use your chicken fajitas to make a giant salad with some crunchy greens and avocado.
4. On the fourth day, it's time for some soup. Simply add the fajitas to your favorite canned bean soup. End the week with some more traditional fajitas or make a fajita quesadilla.

This meal prep plan also works great with Slow Cooker Chicken Fajitas.

Storage and Leftovers

When I make these oven baked chicken fajitas, there normally aren’t any leftovers, they are that good! But if you do have leftovers, store them in the refrigerator using an airtight container for up to 3 days.

You can also freeze them for an easy meal later. Just wait until they are fully cooled and put leftovers in a freezer-safe dish and freeze for up to 3 months. Thaw them overnight in the refrigerator before heating in a skillet.

How to Serve Fajitas

Traditionally, fajitas are served on a flaming hot cast iron pan or skillet. This makes for an exciting presentation, but it’s not always suitable, especially if you have small children.

We normally line up all the fajita toppings and let everyone make their own fajitas right at the table, sans the hot cast iron pan.

But if it’s just you and your spouse, feel free to get fancy and use a heated skillet.

If you enjoy adding sides to your fajitas, these quick refried beans are a perfect companion!
