Detailed Directions and Instructions
Step 1: Preheat the Oven
Preheat the oven to 400°F (200°C). Grease a 9×13 inch baking dish with cooking spray or oil.
Step 2: Cook the Chicken
In a large skillet over medium-high heat, heat 2 tablespoons of avocado oil. Add the bite-sized chicken pieces to the skillet. Cook the chicken until it is browned and cooked thoroughly, approximately 6-8 minutes. Once cooked, remove the chicken from the skillet and set it aside on a plate.
Step 3: Sauté the Vegetables
In the same skillet where the chicken was cooked, add the sliced red, green, and yellow bell peppers along with the sliced onion. Sauté the vegetables until they are tender, about 5-7 minutes. Add 2 cloves of minced garlic to the vegetables and cook for an additional minute until fragrant.
Step 4: Combine Ingredients
Return the cooked chicken pieces to the skillet with the sautéed vegetables. Sprinkle the packet of taco seasoning over the chicken and vegetables, stirring to combine thoroughly. Next, add the can of diced tomatoes with green chiles (do not drain) to the skillet and mix well to incorporate all the ingredients.
Step 5: Add Creamy Mixture
In a separate bowl, combine 4 oz of softened cream cheese and 1/2 cup of sour cream until the mixture is smooth. Pour this creamy mixture into the skillet and stir until the chicken and vegetables are well coated.
Step 6: Transfer to Baking Dish
Transfer the entire mixture from the skillet into the prepared 9×13 inch baking dish. Spread it out evenly.
Step 7: Add Cheese
Sprinkle 1 cup of shredded Monterey Jack cheese and 1 cup of shredded sharp cheddar cheese evenly over the top of the casserole.
Step 8: Bake
Place the baking dish in the preheated oven. Bake for 20-25 minutes, or until the cheese is melted, bubbly, and slightly golden.
Step 9: Cool and Serve
Once baked, remove the casserole from the oven. Allow it to sit for a few minutes to cool slightly before serving.
