This Creamy Spinach Chicken Bake can be made in only 30 minutes and is perfect for weeknight family dinners. This casserole recipe features chicken thighs, spinach, cream cheese, and mozzarella cheese.


  • 4 boneless, skinless thin chicken thighs
  • 2 Tablespoons (30 milliliters) avocado oil, divided
  • 2 Tablespoons (30 grams) minced garlic
  • 1 teaspoon Italian seasoning
  • 1/2 teaspoon black pepper
  • 1/2 teaspoon salt
  • 1/4 teaspoon paprika
  • 1/8 teaspoon red pepper flakes
  • 7 ounces cream cheese, softened
  • 5 cups (~140 grams) fresh spinach
  • 4 ounces shredded mozzarella cheese

Optional Garnishes:

  • Freshly-cracked black pepper
  • Pinch of paprika


  1. Marinate Chicken: To a freezer bag, add chicken, 1 Tablespoon avocado oil, minced garlic, Italian seasoning, pepper, salt, paprika, and red pepper flakes. Seal bag and, using hands, shake and massage mixture into chicken until marinade ingredients are well-combined. Transfer bag to refrigerator to marinate.
  2. Preheat Oven: Place oven rack in middle of oven, preheat oven to 450 degrees F, and coat 9×13-inch baking pan with nonstick cooking spray.
  3. Wilt Spinach: While oven preheats, in a pan on the stovetop over medium heat, heat remaining 1 Tablespoon avocado oil. Add spinach and allow to wilt and for excess liquid to cook off, then remove pan from the heat and set pan aside.
  4. Prepare Chicken Bake: Unseal bag of marinated chicken and, using tongs, transfer chicken to prepared baking pan. Using a knife, spread softened cream cheese atop chicken pieces and then, using tongs, lay spinach atop cream cheese. Sprinkle shredded mozzarella on top.
  5. Bake: Transfer pan to oven to bake until chicken has reached an internal temperature of 165 degrees F, about 20-22 minutes.
  6. Garnish and Serve: Remove pan from oven, garnish with pepper and paprika, then serve.

Recipe Notes:

Storage: Store leftovers in an airtight container in the refrigerator for up to 3 days or up to 3 months in the freezer.

Reheating Instructions: If frozen, allow the chicken bake to thaw overnight in the fridge. Then, to reheat, bake in the oven at 350 degrees F for 15-25 minutes or in the microwave until heated throughout, about 1-2 minutes, depending on the wattage of your microwave.
