**Instructions:**
1. **Preheat the Oven:**
– Preheat your oven to 375°F (190°C).
2. **Prepare the Chicken:**
– Season the chicken breasts with Italian seasoning, garlic powder, onion powder, salt, and pepper.
– Heat olive oil in a large skillet over medium-high heat.
– Sear the chicken breasts on both sides until golden brown, about 3-4 minutes per side. They don’t need to be fully cooked through, as they will finish cooking in the oven.
3. **Assemble the Casserole:**
– Spread a thin layer of marinara sauce on the bottom of a 9×13-inch baking dish.
– Place the seared chicken breasts in the dish.
– Pour the remaining marinara sauce over the chicken, ensuring each piece is well coated.
– Sprinkle the shredded mozzarella and grated Parmesan cheese evenly over the top.
– If you like a crunchy topping, mix the breadcrumbs with a little olive oil and sprinkle them over the cheese.
4. **Bake:**
– Bake in the preheated oven for 20-25 minutes, or until the cheese is melted and bubbly and the chicken is cooked through (internal temperature should reach 165°F or 74°C).
5. **Garnish and Serve:**
– Remove the casserole from the oven and let it cool slightly before serving.
– Garnish with chopped fresh basil or parsley.
Serve this Chicken Parmesan Casserole with a side of pasta, garlic bread, or a fresh salad for a complete meal. It’s a comforting, cheesy dish that’s sure to be a hit!
