How to Make Baked Fajita Chicken Breasts
Step 1: Preheat and Prep
Start by heating your oven to 400°F (200°C). This temperature is perfect for baking the chicken until it’s juicy inside with a lovely golden finish on the outside. While the oven preheats, gather all your ingredients—this will make the process smooth and stress-free.
Step 2: Mix the Marinade
In a small bowl, whisk together the olive oil, lime juice, chili powder, smoked paprika, cumin, garlic powder, onion powder, cayenne pepper (if you like it spicy), salt, and black pepper. This simple yet powerful marinade infuses the chicken with irresistible flavor and helps lock in moisture during baking.
Step 3: Season the Chicken
Arrange the chicken breasts in a large baking dish. Pour the marinade over them, using your hands or a brush to make sure both sides are generously coated. Take a moment to really massage the spices into the chicken—this step makes all the difference for flavor in your Baked Fajita Chicken Breasts.
Step 4: Add the Veggies
Next, scatter your sliced red, yellow, and green bell peppers, along with the red onion, all around and on top of the chicken. The veggies not only add color and sweetness, but they also soak up the savory juices as everything bakes together.
Step 5: Bake to Perfection
Slide the baking dish into your preheated oven and bake for 25 to 30 minutes. The chicken should reach an internal temperature of 165°F (74°C) and the veggies will be tender and slightly caramelized at the edges. Let the chicken rest for about 5 minutes after baking—this helps the juices redistribute for extra succulence.
Step 6: Slice and Serve
Once rested, slice the chicken breasts into strips for classic fajita appeal. Serve the chicken and veggies warm, straight from the pan, and get ready to enjoy the flavor-packed magic of Baked Fajita Chicken Breasts.
How to Serve Baked Fajita Chicken Breasts

Garnishes
Finish your Baked Fajita Chicken Breasts with a flourish of fresh garnishes. A sprinkle of chopped cilantro, a few lime wedges for extra zing, and maybe a dollop of cool sour cream or creamy avocado slices will take every bite to the next level. Don’t be afraid to add your favorite hot sauce or crumbled queso fresco for an extra layer of flavor!
Side Dishes
This dish is endlessly versatile when it comes to sides. Serve your fajita chicken alongside warm tortillas for build-your-own tacos, spoon it over fluffy rice or cilantro-lime cauliflower rice, or pile it onto a crisp green salad. Refried beans or a scoop of guacamole are also perfect companions for this colorful meal.
Creative Ways to Present
For a fun family-style presentation, serve the chicken and veggies straight from the baking dish and let everyone build their own fajitas with their favorite toppings. Or, try slicing the chicken before baking for a fajita bowl-style meal, complete with rice, beans, and all the fixings. Baked Fajita Chicken Breasts also make a fantastic filling for wraps, quesadillas, or even as a vibrant salad topper for lunch the next day!
Make Ahead and Storage
Storing Leftovers
Leftover Baked Fajita Chicken Breasts store beautifully. Simply let everything cool, then transfer the chicken and veggies to an airtight container. They’ll stay fresh in the refrigerator for up to 3 days, making them perfect for meal prepping or easy lunches.
Freezing
If you want to keep your fajita chicken on hand for busy nights, freezing is a great option. Slice the chicken and package it with the veggies in freezer-safe containers or zip-top bags, pressing out as much air as possible. They’ll keep well for up to 2 months. Just be sure to thaw in the refrigerator overnight before reheating.
Reheating
To bring your Baked Fajita Chicken Breasts back to life, gently reheat them in a covered skillet over medium heat with a splash of water or chicken broth. You can also use the microwave—just cover and heat in 30-second bursts until warmed through. The veggies and chicken stay surprisingly juicy and flavorful, even after being reheated!
FAQs
Can I use chicken thighs instead of breasts?
Absolutely! Chicken thighs work beautifully in this recipe and tend to be even juicier. Just adjust the baking time as needed; they may require a few extra minutes to cook through.
Is this recipe spicy?
By default, Baked Fajita Chicken Breasts have a gentle warmth from the chili powder and smoked paprika. If you’re sensitive to spice, simply leave out the cayenne pepper, or add more if you love extra heat!
Can I prep this meal in advance?
Yes, you can marinate the chicken and slice the veggies up to a day ahead. Keep them separate in the fridge, then assemble and bake when you’re ready for dinner. This makes weeknight cooking even easier.
What’s the best way to slice the chicken?
Letting the chicken rest after baking is key to juicy slices. Use a sharp knife to cut it against the grain into thin strips—this is the classic fajita style and makes every bite extra tender.
Can I make this dairy-free and gluten-free?
Baked Fajita Chicken Breasts are naturally gluten-free and dairy-free as written! Just be sure to serve with gluten-free sides like rice or corn tortillas and skip any cheese or sour cream garnishes if needed.
