Ingredients for Fajita Chicken Casserole
Here’s everything you need to create this hearty and flavorful meal:
Main Ingredients:
- 2 cups cooked, shredded chicken (rotisserie works great)
- 1 red bell pepper, thinly sliced
- 1 yellow bell pepper, thinly sliced
- 1 green bell pepper, thinly sliced
- 1 medium onion, sliced
- 1 tablespoon olive oil
Fajita Seasoning Blend:
- 1 teaspoon ground cumin
- 1 teaspoon chili powder
- ½ teaspoon garlic powder
- ½ teaspoon onion powder
- ½ teaspoon smoked paprika
- Salt and pepper to taste
Creamy Base:
- 1 cup sour cream
- 4 oz cream cheese, softened
- 1 cup shredded cheddar cheese
- ½ cup shredded Monterey Jack cheese
Optional Toppings and Garnishes:
- ¼ cup chopped fresh cilantro
- Sliced jalapeños
- Crushed tortilla chips
- Lime wedges for serving
Step-by-Step Instructions
1. Sauté the Vegetables
Start by heating olive oil in a large skillet over medium-high heat. Add sliced onions and bell peppers. Cook for 6-7 minutes, stirring occasionally, until they begin to soften and develop a light char.
Sprinkle the fajita seasoning blend over the vegetables. Stir to coat them well with the spices. Remove from heat and set aside.
2. Prepare the Creamy Chicken Mixture
In a large mixing bowl, combine softened cream cheese and sour cream. Beat until smooth. Add half of the shredded cheddar and Monterey Jack cheese. Mix well.
Stir in the cooked shredded chicken and the sautéed pepper-onion mixture. Mix until all the ingredients are fully incorporated.
3. Assemble the Casserole
Preheat your oven to 375°F (190°C). Grease a 9x13-inch casserole dish.
Spread the chicken mixture evenly in the prepared dish. Top with the remaining shredded cheeses. You can also sprinkle some sliced jalapeños or crushed tortilla chips over the top for extra flavor and texture.
4. Bake to Perfection
Bake uncovered for 20-25 minutes, or until the casserole is hot and bubbling and the cheese is melted and golden.
Let it rest for 5-10 minutes before serving. This allows the casserole to firm up slightly and makes slicing easier.
5. Garnish and Serve
Garnish with chopped fresh cilantro and serve with lime wedges. Pair it with rice, tortilla chips, or warm flour tortillas.
