Easy Chicken Fajita Bake
A simple, flavorful Mexican-inspired chicken fajita bake, perfect for easy weeknight dinners and healthy meal prepping. This recipe combines tender seasoned chicken, colorful bell peppers, and onions, all baked together for minimal cleanup and maximum taste.
Ingredients
- 1.5 lb boneless skinless chicken breasts
- 2 medium bell peppers any color
- 1 medium red onion sliced
- 2 tbsp olive oil
- 2 tbsp fajita seasoning
- 1 lime juiced (for serving)
- 0.25 cup fresh cilantro chopped (for serving
Instructions
- Preheat your oven to 400°F (200°C). Lightly grease a large baking sheet or 9x13 inch baking dish.
- Cut the chicken breasts into 1-inch strips or cubes. Slice the bell peppers and red onion into thin strips.
- In a large bowl, combine the chicken, bell peppers, and red onion. Drizzle with olive oil and sprinkle generously with fajita seasoning. Toss until everything is evenly coated.
- Spread the chicken and vegetable mixture in a single layer on the prepared baking sheet or dish.
- Bake for 20-25 minutes, or until the chicken is cooked through and the vegetables are tender-crisp. You can stir halfway through cooking for even browning.
- Remove from the oven, squeeze fresh lime juice over the top, and garnish with chopped fresh cilantro, if desired. Serve immediately or portion into meal prep containers.
Notes
Serve your chicken fajita bake with warm tortillas, brown rice, a fresh green salad, or over a bed of quinoa. For an extra kick, add sliced jalapeños before baking. A sprinkle of fresh cilantro and a squeeze of lime juice after cooking will brighten all the flavors. You can also add black beans or corn to the bake for extra bulk and nutrition.
