This Keto Chicken Parmesan Casserole is a low-carb, deliciously cheesy baked dish perfect for a comforting weeknight dinner. Combining tender cooked chicken with flavorful sugar-free marinara and Italian seasonings, it's topped with melted mozzarella and Parmesan for that classic Chicken Parmesan taste without the carbs.

Ingredients

Chicken Mixture

  • 2 cups cooked chicken, shredded or diced
  • 2 cups marinara sauce (sugar-free)
  • 2 cloves garlic, minced
  • 1 teaspoon Italian seasoning
  • Salt and pepper to taste

Topping

  • 1 cup shredded mozzarella cheese
  • 1/2 cup grated Parmesan cheese

Other

  • Olive oil for greasing

Instructions

  1. Preheat Oven: Preheat your oven to 375°F (190°C) to get it ready for baking the casserole.
  2. Mix Ingredients: In a large mixing bowl, combine the shredded or diced cooked chicken with the sugar-free marinara sauce, minced garlic, Italian seasoning, salt, and pepper. Stir everything together until well combined to ensure even flavor distribution.
  3. Prepare Baking Dish: Grease a 9×13-inch baking dish with olive oil to prevent sticking and place the chicken mixture evenly into the dish.
  4. Add Cheese Toppings: Sprinkle the shredded mozzarella cheese followed by the grated Parmesan cheese evenly over the top of the chicken mixture to create a rich cheesy layer.
  5. Bake: Place the baking dish in the preheated oven and bake for 25-30 minutes until the cheese is melted, bubbly, and lightly golden on top.
  6. Cool and Serve: Remove from the oven and let the casserole cool slightly before serving to allow it to set for easy slicing and enjoying.

Notes

  • Use cooked chicken from rotisserie, leftover roasted chicken, or quickly poached chicken breasts for convenience.
  • Ensure marinara sauce is sugar-free or very low sugar to keep the recipe keto-friendly.
  • Italian seasoning can be substituted with a mix of dried oregano, basil, and thyme if unavailable.
  • Feel free to add chopped spinach or mushrooms to the mixture for extra veggies.
  • Leftovers can be refrigerated for up to 3 days and reheated in the oven or microwave.
