Essential Ingredients

Boneless, Skinless Chicken Breasts: I usually use about 3-4 chicken breasts, but feel free to adjust based on your crowd size.

Onion: A medium onion adds depth and sweetness to the casserole.

Shredded Cheese: Cheddar or Monterey Jack melts beautifully and adds creaminess.
-
Cumin Powder: A key spice that brings warmth and earthy tones to the dish.
-

Let’s Make it Together
Preheat the Oven: Start by preheating your oven to 375°F (190°C). This ensures an evenly baked casserole that’s perfectly gooey at the end.
Sauté the Vegetables: In a large skillet over medium heat, add olive oil. Once hot, throw in diced onions and bell peppers until they soften and become fragrant—about 5 minutes should do it.
Add the Chicken: Dice boneless chicken breasts into bite-sized pieces. Add them to the skillet with sautéed veggies along with cumin and chili powder. Cook until the chicken turns golden brown and no longer pink—about 7-10 minutes.
Layer It Up: Grab your tortillas! In a large baking dish, lay half of them as a base. Spread half of the chicken mixture on top, followed by half of the salsa and cheese. Repeat layers for that extra deliciousness.
Bake Until Golden: Cover your baking dish with aluminum foil and bake for about 25 minutes. Remove the foil for the last 10 minutes so that cheese gets gloriously bubbly and golden.
Serve & Enjoy: Once baked to perfection, let it cool slightly before serving. Garnish with fresh cilantro if you like—a little freshness never hurt anyone!
Now you’ve got yourself an amazing Mexican chicken casserole! Dive in while it’s hot; trust me—it won’t last long!
