Instructions

Preheat the oven to 375°F (190°C).
Lightly coat the chicken breasts with avocado oil spray and season both sides with salt and pepper.
In a skillet, sear the chicken breasts over medium-high heat for 2-3 minutes per side until lightly browned. Remove from heat.
In a medium bowl, combine the mayonnaise, sour cream, Dijon mustard, minced garlic, thyme, paprika, cayenne pepper, and salt and pepper.
Spread half of the shredded cheddar cheese on the bottom of a baking dish. Place the seared chicken breasts on top.
Pour the sauce mixture over the chicken, ensuring it’s evenly coated.
Sprinkle the remaining cheddar cheese on top of the casserole.
Bake for 25-30 minutes or until the chicken reaches an internal temperature of 165°F (74°C) and the cheese is melted and bubbly.
If using, garnish the casserole with scallions and bacon bits.
Serve hot and enjoy!

Notes

For a creamier casserole, you can use ⅓ cup each of mayonnaise and sour cream.
If you prefer more flavor, feel free to add more garlic or cayenne pepper to taste.
This casserole can be made ahead and stored in the fridge for 2-3 days.
