Step‑by‑Step Instructions for Creamy Fajita Chicken Casserole

Step 1: Preheat and Prepare
Begin by preheating your oven to 400°F (200°C). While it heats, lightly oil a 9×13-inch baking dish to prevent sticking. This dish will be the home for your delicious Creamy Fajita Chicken Casserole, so make sure to coat it evenly.

Step 2: Mix the Creamy Base
In a medium bowl, combine the cream cheese, tomato sauce, chicken stock, half of the fajita seasoning, salt, and pepper. Use a hand mixer or a whisk to blend these ingredients until smooth and creamy, creating a rich base for the casserole that will meld beautifully with the chicken and veggies.

Step 3: Prepare the Chicken
Cut the boneless, skinless chicken breasts into bite-sized pieces and place them in the greased baking dish. Sprinkle the remaining fajita seasoning over the chicken, ensuring even coverage. Then, pour the creamy mixture from Step 2 over the chicken, gently tossing to coat the chicken pieces thoroughly.

Step 4: Add Vegetables
Layer the colorful sliced bell peppers and onions on top of the chicken in the baking dish. This not only adds vibrant color but also enhances the overall flavor of your Creamy Fajita Chicken Casserole. Spread the vegetables out evenly for uniform cooking.

Step 5: Sprinkle Cheese and Bake
Generously sprinkle shredded cheddar cheese over the top of the casserole to create a golden, cheesy crust. Place the baking dish in the preheated oven and bake for 15-25 minutes, checking at the 15-minute mark for doneness. You want the chicken to reach an internal temperature of 165°F (74°C) and the cheese to be bubbly.

Step 6: Optional Broil for Crispiness
For an extra touch of indulgence, switch your oven to broil for the last 2 minutes of cooking. Watch closely as the cheese turns a delightful golden brown, adding a crispy texture to your creamy casserole. Once done, remove it from the oven and let it cool for a few minutes.

Step 7: Serve and Enjoy
After allowing the casserole to settle, scoop generous portions onto plates and serve with a dollop of sour cream and slices of avocado if desired. This Creamy Fajita Chicken Casserole is sure to impress with its comforting flavors and inviting presentation!

Storage Tips for Creamy Fajita Chicken Casserole

  • Fridge: Store leftovers in an airtight container for up to 2 days. Be sure to let the casserole cool completely before sealing.

  • Freezer: This flavorful Creamy Fajita Chicken Casserole can be frozen for up to 1 month. Wrap it tightly in plastic wrap and then aluminum foil to prevent freezer burn.

Creamy Baked Fajita Chicken Casserole Recipe FAQs

How do I know when the chicken is ripe for cooking?
