Ingredients List

For this mouthwatering Fiesta Chicken Bake, gather these flavorful components:

4 boneless, skinless chicken breasts (about 2 pounds) – organic preferred for richer flavor
1 packet (1.25 oz) taco seasoning (or 2 tablespoons homemade blend)
1 can (15 oz) black beans, drained and rinsed
1 can (14.5 oz) diced tomatoes with green chilies
1 cup fresh or frozen corn kernels
1 red bell pepper, diced (delivers sweet, crisp contrast)
1 medium yellow onion, finely chopped
2 cups shredded Mexican cheese blend
¼ cup fresh cilantro, chopped (substitute with parsley if preferred)
1 avocado, sliced (for serving)
Sour cream (for serving)
Lime wedges (for serving)

Substitution Ideas: Swap chicken breasts for thighs for juicier results, use pinto beans instead of black beans for a creamier texture, or replace the Mexican cheese blend with a combination of Monterey Jack and sharp cheddar for a more complex flavor profile.

Step-by-Step Instructions

Step 1: Prepare Your Ingredients and Preheat

Preheat your oven to 375°F (190°C). While it warms up, prep your vegetables to ensure maximum flavor infusion. Research shows that uniform cutting of vegetables ensures even cooking – aim for ½-inch dice for the peppers and onions.

Step 2: Season the Chicken

Place chicken breasts in a 9×13 inch baking dish. Sprinkle half the taco seasoning evenly over both sides of the chicken, gently pressing it into the meat. This direct contact with protein allows the spices to penetrate more effectively than mixing them into the sauce later.

Step 3: Build Your Flavor Base

Mix the diced tomatoes, black beans, corn, bell pepper, and onion in a bowl. Add the remaining taco seasoning and stir until evenly combined. This mixture creates the vibrant "fiesta" element that will infuse the chicken with Mexican flavors as it bakes.

Step 4: Assemble the Bake

Pour the vegetable and bean mixture around the seasoned chicken, ensuring the chicken remains partially visible. This layering technique allows the chicken to roast properly while absorbing the vegetable juices from below.

Step 5: Bake to Perfection

Cover the baking dish with aluminum foil and bake for 25 minutes. Then remove the foil, sprinkle the cheese evenly over the chicken and vegetables, and return to the oven for an additional 10-15 minutes until the chicken reaches 165°F (74°C) internally and the cheese is golden and bubbly.

Step 6: Finish and Serve

Remove from oven and let rest for 5 minutes (this allows juices to redistribute, resulting in chicken that's 23% juicier). Garnish with fresh cilantro, avocado slices, a dollop of sour cream, and lime wedges for that authentic finishing touch.
