Ingredients

2 boneless, skinless chicken breasts, cooked and cut into bite-size pieces
Short, cooked chicken pieces add protein and a meaty texture throughout the casserole.
1 tablespoon olive oil
Used to sear the chicken and add a light, savory finish.
1 teaspoon onion powder
Adds a mellow, savory onion flavor without extra chopping.
1 teaspoon garlic powder
Provides warm garlic notes that blend into the creamy sauce.
1 teaspoon seasoned salt
Brings a balanced salty and herby seasoning to the chicken and casserole.
Salt and black pepper, to taste
Adjusts seasoning to your preference.
2 cans (10.5 oz each) cream of chicken soup
Forms the creamy, savory base of the casserole.
1 can (10.5 oz) cream of mushroom soup
Adds depth and umami to the sauce.
1/2 cup heavy whipping cream
Enriches the sauce for a silky, indulgent texture.
3 cups shredded Colby Jack cheese, divided
Two cups are mixed into the filling for creaminess, and one cup tops the casserole for a melty golden crust.

Step-by-Step Instructions

Preheat the oven to 350°F (175°C) and position an oven rack in the center.
Preheating ensures even baking and a bubbly, golden top.
Heat the olive oil in a skillet over medium heat. Season the chicken breasts with the onion powder, garlic powder, seasoned salt, and additional salt and black pepper. Cook the chicken until golden brown on both sides, about 6 to 10 minutes per side. Use a meat thermometer to ensure the internal temperature reaches 165°F (74°C).
Tip: If breasts are uneven in thickness, gently press or pound them to an even thickness so they cook evenly.
In a large bowl, whisk together the two cans of cream of chicken soup, the cream of mushroom soup, the heavy whipping cream, and 2 cups of shredded Colby Jack cheese until smooth.
Stir until the cheese is well incorporated for a consistent, creamy filling.
Add the cooked, bite-size chicken pieces to the mixture and stir to coat evenly.
Make sure the chicken is well distributed so every serving has both sauce and protein.
Pour the mixture into a baking dish, spreading it evenly. Sprinkle the remaining 1 cup of shredded Colby Jack cheese evenly over the top.
Tip: For an extra golden top, let the casserole sit a few minutes before placing it in the oven so the surface sets slightly.
Bake for 25 to 30 minutes until the cheese is bubbly and golden. Let cool slightly before serving.
Letting it rest for 5 to 10 minutes helps the casserole set so it serves more cleanly.

Tips, Storage & Variations

Tips
- Cut the cooked chicken into uniform bite-size pieces so each bite has even texture.
- Use a meat thermometer to ensure chicken reaches 165°F (74°C) for food safety.
- If your cheese is pre-shredded, give it a quick stir to avoid clumping when mixing into the sauce.
Storage
- Refrigerate leftovers in an airtight container for up to 3 to 4 days.
- Reheat single servings in the microwave until warmed through, or warm the entire dish at 350°F (175°C) until heated.
Freezing
- Assemble the casserole without baking, cover tightly, and freeze for up to 2 months. Thaw overnight in the refrigerator before baking as directed.
- Baked leftovers can be frozen in airtight containers for up to 2 months. Thaw overnight and reheat thoroughly.
Flavor Variations using existing ingredients only
- Extra cheesy: Stir the full 3 cups of cheese into the filling instead of reserving 1 cup for the top for a uniformly cheesy interior.
- Creamier sauce: Add the full 1/2 cup of heavy whipping cream into the filling and let the top remain with 1 cup cheese for extra silkiness.
- Mushroom-forward: Increase the relative mushroom flavor by using the cream of mushroom soup more prominently in the mix while keeping quantities the same.
