Ingredients You’ll Need

3 cups pre cooked chicken (rotisserie or leftover), cut or shredded
1 jar (24 oz) marinara sauce
1 1/2 cups shredded mozzarella cheese
1/2 cup grated Parmesan cheese (fresh is best)
1/2 cup panko breadcrumbs
1 tablespoon olive oil
Optional: 1 cup fresh spinach, 1 cup sliced mushrooms, red pepper flakes to taste

Step by Step Instructions

Preheat your oven to 400°F.
Cut the pre cooked chicken into 1 inch cubes so everything cooks evenly.
In a large bowl, mix the chicken with the marinara sauce until well coated.
Spread the mixture evenly into a greased 9×13 inch baking dish.
Sprinkle the mozzarella and Parmesan over the top.
In a small bowl, stir the panko with olive oil, then scatter it over the cheese.
Bake for 15 to 20 minutes, until the sauce is bubbly and the breadcrumbs are golden. For extra browning, broil for 2 minutes at the end.

Tip: If you are using raw chicken, you would need to cook it first. But this recipe is designed for speed with pre cooked meat.

Tips for the Best Results

Use fresh Parmesan. Pre grated stuff doesn’t melt as smoothly and lacks that nutty punch. Grate it yourself for the best texture.
Avoid dry chicken. Since the chicken is already cooked, you only need to heat it through. Overbaking will dry it out. Stick to 15 minutes and check.
Crispy topping. Panko breadcrumbs give a much crispier finish than regular breadcrumbs. Tossing them with olive oil before adding helps them brown beautifully.
Let it rest. Let the casserole sit for 5 minutes after baking so the sauce thickens slightly and the cheese sets.

Make Ahead and Storage Tips

This casserole is perfect for meal prep. You can assemble it completely (without baking), cover tightly, and refrigerate for up to 24 hours. When ready to bake, add about 5 to 10 minutes to the bake time since you are starting from cold.

Leftovers keep well in the fridge for up to 3 days. Reheat individual portions in the microwave, or warm the whole dish in a 350°F oven until hot. You can also freeze the baked or unbaked casserole for up to 3 months. Wrap tightly in foil, thaw overnight in the fridge, and bake as directed (add extra time if frozen solid).

What to Serve with This Casserole

This dish is hearty on its own, but it pairs beautifully with spaghetti or angel hair pasta tossed in garlic butter. A simple green salad with vinaigrette cuts through the richness, and warm garlic bread is always a hit. For a lighter option, serve with steamed broccoli or roasted zucchini.

Variations to Try

Add veggies: Stir in a handful of fresh spinach or sliced mushrooms with the chicken and sauce.
Spice it up: Sprinkle red pepper flakes over the top before baking for a little heat.
Gluten free: Use gluten free panko or crushed pork rinds for the topping, and serve with gluten free pasta or zucchini noodles.
Low carb / keto: Skip the breadcrumbs and pasta. Use a low sugar marinara and top with extra cheese and crushed pork rinds.
Double it: Need to feed a crowd? Double all ingredients and bake in a larger dish or two 9×13 pans. Increase bake time by about 5 to 10 minutes.
