Ingredients
  

Main Ingredients
  • 1.5 pounds boneless, skinless chicken breasts Choose firm, pale pink breasts with no odor.
  • 8 oz cream cheese, softened Low fat versions change texture; for lactose sensitivity, try dairy free.
  • 1/2 cup sour cream Full fat yields the creamiest mouthfeel.
  • 1.5 cups shredded cheddar cheese Sharp cheddar gives savory punch; freshly shred for best melt.
  • 1/2 cup milk (whole or 2%) Plant milks may alter flavor; add more if sauce is too thick.
  • 3 cloves garlic, minced Fresh garlic releases brighter flavor.
  • 1 teaspoon onion powder
  • 1/2 teaspoon dried thyme
  • Salt and black pepper to taste Season in stages for layered flavor.
  • 2 tablespoons olive oil or butter
  • 2 cups cooked rice or egg noodles (optional) Helps stretch the protein.

Method
 

Cooking Chicken
  1. Dice the chicken breasts into 1-inch cubes or shred if preferred.
  2. Heat olive oil or butter in a large skillet over medium heat.
  3. Add chicken and sauté for 6-8 minutes until cooked through and lightly golden.
  4. Season with salt and pepper, then remove from heat.
Making the Sauce
  1. In a mixing bowl, whisk together softened cream cheese, sour cream, milk, minced garlic, onion powder, dried thyme, salt, and pepper until smooth and pourable.
  2. Combine the cooked chicken with the creamy sauce in a large bowl.
  3. Fold in cooked rice or egg noodles if using.
Baking the Casserole
  1. Pour the mixture into a greased 9×13-inch casserole dish and spread evenly.
  2. Sprinkle shredded cheddar cheese evenly over the top.
  3. Preheat oven to 350°F (175°C) and bake uncovered for 25-30 minutes until bubbly and cheese is melted and golden.
