Ingredients
  

  • 3 cups cooked chicken, shredded or cubed (rotisserie works great)
  • 2 cups low-carb marinara sauce (look for no added sugar)
  • 1/2 cup heavy cream (optional for extra richness)
  • 3 cloves garlic, minced
  • 1 teaspoon Italian seasoning
  • 1/2 teaspoon crushed red pepper flakes (optional)
  • 1/2 teaspoon onion powder
  • Salt and black pepper, to taste
  • 1 cup ricotta cheese (or cottage cheese for extra protein)
  • 1 1/2 cups shredded mozzarella cheese, divided
  • 1/2 cup grated Parmesan cheese, divided
  • 2 tablespoons olive oil
  • Fresh basil or parsley, chopped, for garnish

Method
 

  1. Preheat the oven: Set your oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish with olive oil.
  2. Prep the sauce mixture: In a bowl, combine marinara sauce, heavy cream (if using), garlic, Italian seasoning, red pepper flakes, onion powder, and a pinch of salt and pepper. Stir until smooth.
  3. Season the chicken: Toss the cooked chicken with 2 to 3 tablespoons of the sauce to lightly coat. This keeps it moist while baking.
  4. Layer the casserole: Spread about 1/2 cup of the sauce mixture on the bottom of the baking dish. Add half the chicken in an even layer.
  5. Add the cheeses: Dollop half the ricotta over the chicken, then sprinkle with 3/4 cup mozzarella and 1/4 cup Parmesan.
  6. Repeat the layers: Add the remaining chicken, pour over the rest of the sauce, add the remaining ricotta in small spoonfuls, and top with the remaining mozzarella and Parmesan.
  7. Drizzle and bake: Drizzle the top with olive oil for extra browning. Bake uncovered for 20–25 minutes, or until the cheese is melted and bubbling around the edges.
  8. Broil for color: Switch the oven to broil for 1–3 minutes to get a golden, slightly crispy top. Watch closely to avoid burning.
  9. Rest and garnish: Let the casserole rest for 10 minutes. Sprinkle with chopped basil or parsley before slicing.
  10. Portion for meal prep: Divide into 4–6 servings and transfer to airtight containers. Add extra fresh herbs on top if you like.
