Ingredients

Chicken

• 2 lb (900 g) boneless, skinless chicken breasts, cut into bite-sized pieces
• 1 tablespoon olive oil
• 1 teaspoon garlic powder
• 1 teaspoon Italian seasoning
• ½ teaspoon paprika
• ½ teaspoon salt, or to taste
• ¼ teaspoon black pepper

Sauce and cheese

• 1½ cups (360 g) no-added-sugar marinara sauce
• 1½ cups (170 g) shredded mozzarella cheese
• ½ cup (50 g) freshly grated Parmesan cheese
• 2 cloves garlic, minced
• ½ teaspoon dried oregano
• ¼ teaspoon red pepper flakes, optional
• Fresh basil or parsley, for garnish

Optional crispy topping

• ¼ cup (25 g) grated Parmesan
• 2 tablespoons almond flour
• ½ teaspoon Italian seasoning

Instructions

1. Preheat the oven. Heat to 400°F (200°C). Lightly grease a 9 × 13-inch baking dish.

2. Season the chicken. Place the chicken pieces in a bowl. Add olive oil, garlic powder, Italian seasoning, paprika, salt, and black pepper. Toss until evenly coated.

3. Arrange the chicken. Spread the seasoned chicken in a single layer in the prepared baking dish.

4. Add the sauce. Mix the marinara sauce with minced garlic, oregano, and red pepper flakes. Pour evenly over the chicken.

5. Add the cheese. Sprinkle the mozzarella and Parmesan over the sauce. For a crispy topping, combine the optional Parmesan, almond flour, and Italian seasoning, then sprinkle over the cheese.

6. Bake the casserole. Bake uncovered for approximately 25–30 minutes, depending on the size of the chicken pieces, until the chicken reaches an internal temperature of 165°F (74°C) and the cheese is melted and bubbly.

7. Brown the top. For a golden finish, broil for 1–2 minutes, watching carefully to prevent burning.

8. Rest and serve. Let stand for 5 minutes. Garnish with fresh basil or parsley and serve warm.
