Boneless, skinless chicken breasts or thighs: I prefer thighs for extra juiciness, but breasts work great if you want leaner meat.
Bell peppers: Using a mix of colors not only looks vibrant but offers a range of subtle sweetness and crunch.
Onion: Adds a touch of natural sweetness and depth—red or yellow onions work well here.
Chili powder, paprika, garlic powder, cumin, dried oregano: This signature fajita spice blend infuses the chicken and veggies with a smoky, earthy vibe.
Fine salt and black pepper: Simple seasoning that enhances all the natural flavors without masking them.
Avocado oil: A great choice for high heat baking with a mild flavor that lets the spices shine.

Make It Your Way

One of the best parts about this Easy Chicken Fajita Bake Recipe is how easy it is to tweak. I've played around with different veggies and spice levels to match what my family loves.

Add some heat: If you like it spicy, toss in a pinch of cayenne or some sliced jalapeños before baking—I love the kick it gives!
Swap the veggies: Sometimes I throw in zucchini or mushrooms for extra heartiness, depending on what’s in my fridge.
Go cheese!: Sprinkle shredded cheddar or Monterey Jack over the top in the last 5 minutes of baking for a melty finish that everyone raves about.

Step-by-Step: How I Make Easy Chicken Fajita Bake Recipe

A metal tray filled with several layers of food: the bottom layer has slightly glossy sliced red bell peppers and orange bell peppers, cut into long strips, mixed with thinly sliced red onions showing purple and white tones; the next layer shows raw, pale pink pieces of chicken scattered evenly on top, sprinkled with black pepper. On the left side of the tray, a bunch of fresh green cilantro with leaves is partially on a white marbled surface alongside three lime wedges in bright green and yellow shades. A crumpled blue and white striped cloth lies beneath the tray on the white marbled surface. Photo taken with an iphone --ar 2:3 --v 7

Step 1: Prepping and seasoning everything

Start by preheating your oven to 375℉ and lining a large rimmed baking sheet with parchment paper to keep things simple for cleanup. Slice your chicken, peppers, and onion into even strips. Then, toss everything together in a big mixing bowl with avocado oil and the seasoning blend. Make sure the chicken and veggies are well coated—this ensures every bite bursts with flavor.

Step 2: Baking to perfection

Spread the chicken and veggie mixture evenly across the parchment-lined baking sheet. Pop it in the oven and bake for 20-22 minutes until the chicken is cooked through and the veggies are tender but still have a nice bite. Keep an eye on it—the thin strips cook quickly, so you want juicy chicken without drying it out.

Step 3: Serving it up your way

Once out of the oven, you can get creative: serve over corn tortillas with guac and salsa, pile it on lettuce wraps for a low-carb option, or spoon it over baked sweet potatoes. I like a variety of textures and colors on my plate, so I tend to mix things up based on mood and what’s in the pantry.

Top Tip

Trust me, after several attempts, I’ve learned that the key to juicy chicken and crisp-tender veggies is balance in timing and even slicing. Here are some nuggets to help you nail it the first time.

Uniform slices: Slice your chicken and vegetables into similar thickness to ensure everything cooks evenly—no one wants overcooked chicken or mushy peppers.
Don't overcrowd the pan: Spread ingredients out so they roast instead of steam. I used to pile on too much at once, which made my veggies soggy.
Check internal temperature: To make sure the chicken is cooked safely and remains juicy, I recommend using a meat thermometer aiming for 165℉.
Let it rest briefly: After baking, allow the fajita bake to rest for 3-5 minutes. It helps the juices redistribute and makes serving easier.

How to Serve Easy Chicken Fajita Bake Recipe

chicken fajita bake - Serving Suggestion

Garnishes

My go-to garnishes are simple: dollops of sour cream, fresh cilantro, sliced avocado, and a squeeze of lime. These add creamy, fresh notes that cut through the smoky spices beautifully.

Side Dishes

I often pair this bake with Spanish rice or a simple black bean salad for balanced nutrition. A crisp green salad or crunchy tortilla chips are also fantastic companions.

Creative Ways to Present

For a fun family dinner, try serving the fajita bake in warm corn tortillas as a taco bar where everyone can add their own toppings. Or, scoop it atop a baked sweet potato with some melted cheese for a cozy twist during colder months.

Make Ahead and Storage

Storing Leftovers

I store leftovers in an airtight container in the fridge and they keep well for up to 3 days. When I reheat, I add a splash of water or broth to keep the chicken moist and the peppers vibrant.

Freezing

This bake freezes nicely if you want to meal prep. After cooling completely, portion it into freezer-safe containers. It reheats well straight from frozen if covered and baked at 350℉ until warmed through.

Reheating

I prefer reheating in the oven or air fryer to keep the peppers from getting soggy. A quick 10-15 minutes at 350℉ usually does the trick to regain that fresh-out-of-the-oven texture.

What sides go best with this fajita bake?

Great sides include Spanish rice, black beans, or a fresh green salad. For a low-carb option, serve it over cauliflower rice or wrapped in lettuce leaves for a complete meal.

Yes, you can prep the ingredients ahead and assemble the bake shortly before cooking. Leftovers store well in the refrigerator for up to 3 days or can be frozen for longer storage.

The spice level is mild and approachable for most tastes, thanks to the balanced use of chili powder and paprika. You can easily adjust the heat by adding cayenne or jalapeños if you prefer more kick.
