Ingredients

  • Boneless skinless chicken breasts: Choose fresh chicken for tenderness and slice evenly for quick cooking
  • Ripe mango: The sweetest mangoes will give you the best flavor Press gently to check for slight give and fruity aroma
  • Red yellow and green bell peppers: Pick firm glossy peppers for crunch and color They bring vibrant flavor and lots of vitamins
  • Red onion: Slices add a gentle sweetness and depth to the dish
  • Fresh garlic: Freshly minced garlic brings big flavor compared to pre-minced jars
  • Olive oil: Use extra virgin for the best richness and for helping spices coat everything evenly
  • Chili powder and ground cumin: These create the classic fajita flavor earthy and bold
  • Smoked paprika: Use Spanish-style for a hint of smoky warmth
  • Ground coriander and dried oregano: Build complexity and slightly citrusy notes
  • Salt and black pepper: Essential for balance Always taste and adjust before topping with cheese
  • Shredded cheddar and Monterey Jack cheeses: Look for high-quality blocks and shred yourself for the smoothest melt
  • Fresh cilantro: Freshness and color Chop just before serving
  • Lime wedges: Serve on the side for zesty brightness Squeeze over each portion for the best flavor

Instructions

Prepare the Oven and Dish:
Preheat your oven to a hot 200 degrees Celsius or 400 degrees Fahrenheit. Lightly grease a large casserole dish so the ingredients will not stick.
Coat the Chicken with Spice Blend:
Place the chicken strips in a large mixing bowl. Drizzle in olive oil and sprinkle the chili powder, cumin, smoked paprika, coriander, oregano, salt, and pepper. Toss thoroughly with your hands or tongs so every strip is well coated with spices.
Mix Vegetables and Mango:
Add the sliced bell peppers, red onion, minced garlic, and diced mango directly to the bowl with chicken. Fold everything together gently to keep the fruit intact while ensuring even mixing.
Build the Casserole:
Spoon the entire mixture into your prepared casserole dish. Spread everything evenly so the chicken and vegetables roast consistently and the mango infuses every bite.
Bake Until Tender:
Place the dish in your hot oven and bake for twenty five minutes. You want the chicken cooked through and the bell peppers just softened but still holding some color.
Add the Cheese:
Pull the casserole from the oven briefly and scatter both kinds of shredded cheese in an even layer. This extra step promises every bite gets some gooey cheesy top.
Finish and Serve:
Return the dish to the oven for eight to ten more minutes. Watch for the cheese to become fully melted golden and bubbling. Remove from the oven and let rest a couple minutes Garnish with plenty of chopped cilantro and a squeeze of lime right before serving for extra brightness.

I have always had a soft spot for sweet and savory combinations and fresh mango has become my favorite secret addition. Once when my niece helped me make this casserole for a birthday dinner she was so proud of dicing the mangoes perfectly it is a memory I will always treasure.

Ingredient Substitutions

Swap the chicken for boneless thighs if you prefer a juicier bite If you are dairy free shredded plant-based cheese works well For a different tropical note try diced pineapple instead of mango You can also play with pepper colors based on what you have on hand Red onions can be swapped for white or yellow
