- 1/2 teaspoon Diamond Crystal kosher salt (or 1/4 teaspoon of any other salt)
- 1/4 teaspoon black pepper
- Sauce:
- 1/4 cup mayonnaise (1/3 cup for a creamier casserole)
- 1/4 cup sour cream (1/3 cup for a creamier casserole)
- 1 tablespoon Dijon mustard
- 1 tablespoon fresh garlic, minced
- 1/2 teaspoon Diamond Crystal kosher salt (or 1/4 teaspoon of any other salt)
- 1/4 teaspoon black pepper
- 1/2 teaspoon dried thyme

- 1/4 teaspoon cayenne pepper
- 1 cup sharp cheddar cheese, shredded (divided)
- Topping:
- 1/4 cup scallions, sliced (green parts only)
- 1/4 cup bacon bits, room temperature
Instructions
- Preheat the oven to 450°F (232°C). Line a rimmed baking dish with foil and grease the foil. Place the chicken breasts in the prepared pan. Spray them with avocado oil and sprinkle with salt and pepper. Bake for about 20 minutes until cooked through. Tip: Make sure the chicken is thoroughly cooked by checking it reaches an internal temperature of 165°F (74°C).
- Grease a 2-quart casserole dish. In a large bowl, combine mayonnaise, sour cream, Dijon mustard, minced garlic, salt, pepper, dried thyme, paprika, cayenne, and 1/2 cup of shredded cheddar. Tip: Mixing these ingredients well will ensure a uniform flavor throughout the casserole.
- Once the chicken is cooked, remove it from the oven but keep the oven on. Let the chicken cool slightly, then cut it into cubes or shred it. Add the chicken to the bowl with the sauce mixture and toss to coat.
- Transfer the coated mixture to the prepared casserole dish. Sprinkle the remaining 1/2 cup of shredded cheddar on top. Bake for about 10 minutes until the cheese is melted and the casserole is heated through.
