A quick and easy weeknight casserole featuring tender chicken, rich marinara, and gooey melted cheese, all baked in one pan for a comforting Italian-inspired dinner.

Ingredients

Scale
  • 2 large boneless, skinless chicken breasts (about 1 lb / 450 g), cut into bite-sized pieces
  • 2 cups (480 ml) marinara sauce, store-bought or homemade
  • 2 cups (200 g) shredded mozzarella cheese, freshly shredded
  • ½ cup (50 g) grated parmesan cheese
  • 3 cloves garlic, minced
  • 1 tsp Italian seasoning (oregano, basil, thyme blend)
  • Salt and pepper, to taste
  • 2 tbsp olive oil
  • Optional: 8 oz (225 g) cooked pasta (penne or rigatoni)

Instructions

  1. Preheat your oven to 375°F (190°C).
  2. Cut chicken breasts into bite-sized pieces. Toss in a mixing bowl with olive oil, Italian seasoning, salt, and pepper until lightly coated.
  3. Spread 1 cup (240 ml) marinara sauce evenly on the bottom of an 8×8 inch casserole dish. If using cooked pasta, layer half of it here.
  4. Distribute the seasoned chicken evenly over the sauce or pasta.
  5. Sprinkle minced garlic over the chicken.
  6. Pour the remaining 1 cup (240 ml) marinara sauce over the chicken and spread gently.
  7. Sprinkle shredded mozzarella evenly over the top, then add grated parmesan cheese.
  8. Bake uncovered for 35-40 minutes until chicken reaches an internal temperature of 165°F (74°C) and cheese is golden and bubbly.
  9. Rest casserole for 5-10 minutes before serving.

Notes

If cheese browns too quickly, tent casserole loosely with foil to prevent burning. Use fresh shredded mozzarella for best melt and texture. Avoid overcrowding chicken pieces to ensure even cooking. Rest casserole before serving for easier slicing. Can substitute chicken thighs for juicier meat and adjust bake time accordingly. Leftovers keep well refrigerated for 3 days or frozen for up to 2 months.
