🛒 Ingredients You’ll Need (With Notes)
This recipe serves 6 generously. Each ingredient plays a key role in balancing flavor and texture.
- 3 cups cooked chicken (diced or shredded)
- Rotisserie chicken works wonderfully. Boneless thighs give richer flavor, while chicken breasts keep it lean.
- 2 cups marinara sauce
- Homemade or store-bought. Choose a thick, flavorful sauce to avoid watery results.
- 2 cups shredded mozzarella cheese
- Provides that irresistible gooey melt. Use part-skim for a lighter version.
- ½ cup grated Parmesan cheese
- Adds sharp, salty depth.
- 1 cup Italian-style breadcrumbs
- The key to the crispy topping. Can be swapped with panko for extra crunch.
- 2 tablespoons olive oil or melted butter
- Helps brown the breadcrumb topping.
- 1 teaspoon garlic powder
- Enhances the savory notes.
- ½ teaspoon dried oregano
- Brings a touch of herby Italian flavor.
- Salt and black pepper
- To taste—don’t overdo it if your marinara is already salty.
- Fresh basil or parsley (optional)
- For garnish and freshness.
👉 Optional Add-Ins: cooked pasta, sautéed spinach, roasted zucchini, or even mushrooms can be layered in for extra nutrition.
👩🍳 Step-by-Step Instructions
1. Preheat Oven and Prep Dish
- Preheat your oven to 375°F (190°C).
- Lightly grease a 9×13-inch baking dish or spray with nonstick cooking spray.
2. Layer the Casserole
- Spread half of the marinara sauce on the bottom.
- Add the cooked chicken evenly over the sauce.
- Season with garlic powder, oregano, salt, and pepper.
- Spread the remaining marinara over the chicken.
- Sprinkle with mozzarella and half of the Parmesan.
3. Add Breadcrumb Topping
- In a small bowl, combine breadcrumbs, remaining Parmesan, and olive oil or melted butter.
- Mix until crumbly, then sprinkle evenly over the top.
4. Bake
- Bake uncovered for 25–30 minutes until bubbly and golden on top.
- For extra crispiness, switch to broil for the last 2–3 minutes. (Keep a close eye to avoid burning!)
5. Garnish and Serve
- Let rest for 5 minutes before serving—this helps the layers set.
- Garnish with fresh basil or parsley for color and flavor.
Serve hot with pasta, garlic bread, or a crisp salad.
💡 Pro Tips for Success
- Use rotisserie chicken for convenience and flavor.
- Don’t oversauce—too much marinara will make it soggy.
- Broil briefly at the end for a restaurant-style golden crust.
- Cook veggies first if adding them—this prevents excess water.
- Let it rest before cutting so the cheese sets and doesn’t slide apart.
