🌶️ Fajita Chicken Casserole

Ingredients:

• 2 large chicken breasts (about 500g), cooked & shredded (or rotisserie chicken)

• 2 bell peppers (any color, sliced)

• 1 medium onion, thinly sliced

• 2 cloves garlic, minced

• 1 tbsp olive oil

• 1 packet fajita seasoning (or homemade: 1 tsp chili powder, 1 tsp paprika, ½ tsp cumin, ½ tsp garlic powder, ½ tsp onion powder, ½ tsp salt, ¼ tsp cayenne)

• 1 cup sour cream (or Greek yogurt for lighter version)

• 1 can (10 oz / 284g) cream of chicken soup (or cream of mushroom)

• 1 ½ cups shredded cheese (cheddar, Monterey Jack, or Mexican blend)

• 1 cup cooked rice or pasta (optional, for a heartier casserole)

• Fresh cilantro or green onions, chopped (for garnish)

• Lime wedges, for serving

Instructions:

1. Prep the Chicken

   • If using raw chicken breasts: season lightly with salt & pepper, bake or pan-cook until fully cooked (internal temp 165°F / 75°C). Shred or cube.

   • If using rotisserie chicken: simply shred the meat.

2. Cook the Veggies

   • Heat olive oil in a skillet over medium-high heat.

   • Add onion & bell peppers, sauté 4–5 minutes until softened.

   • Stir in garlic and fajita seasoning. Cook for 1 more minute until fragrant.

3. Mix the Base

   • In a large bowl, combine shredded chicken, sautéed peppers/onions, sour cream, cream of chicken soup, and half of the shredded cheese.

   • If using rice or pasta, fold it in now.

4. Assemble the Casserole

   • Preheat oven to 375°F / 190°C.

   • Grease a baking dish (9×13 works well).

   • Spread the chicken mixture evenly.

   • Sprinkle the rest of the cheese on top.

5. Bake

   • Bake uncovered for 20–25 minutes, until hot, bubbly, and cheese is melted with golden spots.

6. Serve

   • Garnish with fresh cilantro or green onions.

   • Serve with warm tortillas, tortilla chips, or a simple side salad.

   • A squeeze of fresh lime on top brightens the flavors.

✨ Variations & Tips:

• Add black beans or corn for extra Tex-Mex flair.

• Spice it up with jalapeños or extra chili powder.

• Make it low-carb by skipping rice/pasta and baking over a layer of sautéed zucchini slices instead.
