Ingredients You’ll Need

recipe ingredients in small bowls and labeled

Pasta Base

Chicken: Protein-packed and hearty. Swap for turkey or leftover rotisserie chicken for easy meals.
Gluten-free pasta (penne pasta or rotini): Provides the base for the casserole. Regular pasta can be used if gluten isn’t a concern. I use the Jovial brand.
Cherry tomatoes: Adds a burst of freshness and natural sweetness; swap with grape tomatoes or diced Roma tomatoes if needed.
Marinara sauce: Creates a rich, savory foundation for the dish; use your favorite store-bought or homemade marinara for customization.
Chicken broth: Helps thin the marinara sauce slightly while enhancing the savory depth; vegetable broth works for a plant-based twist.
Garlic: Adds a robust and aromatic flavor; garlic powder can be a backup option.
Butter: Enhances the richness of the dish and balances flavors; use dairy-free butter if needed.

Topping

Gluten-free breadcrumbs or crushed gluten-free crackers: Creates a crispy, golden crust. Regular breadcrumbs can be used if gluten isn’t a concern.
Garlic powder: Adds a hint of savory, garlicky flavor to the topping; a fresh garlic rub can also work.
Onion powder: Provides a subtle sweetness and depth to the topping; finely grated onion could be a fresh substitute.
Italian seasoning: Brings a blend of herbs to enhance the casserole’s flavor; use a mix of dried basil, oregano, and thyme if you don’t have it on hand.
Butter: Helps bind the topping and creates a golden, crunchy texture; replace with dairy-free butter for a lighter option.
Salt and black pepper: Essential for seasoning.
Grated Parmesan cheese (optional): Adds a nutty, salty layer of flavor; swap with nutritional yeast or a dairy-free Parmesan alternative if needed.
Mozzarella cheese: Creates that gooey, melty finish; opt for a dairy-free mozzarella if needed.
Fresh basil: Adds a pop of color and fresh, peppery flavor; fresh parsley or even arugula could be used in a pinch.

Recipe Variations

For a little heat, sprinkle in some red pepper flakes or a pinch of cayenne pepper.
Add a nutrient boost by folding fresh spinach into the sauce before baking. The spinach wilts beautifully, adding both flavor and color to the dish.
If you love garlic, roast a few cloves and stir them into the sauce for a sweet, caramelized twist! You can also try making garlic confit to add to your casserole.

How to Make this Chicken Parmesan Recipe

Step 1: Preheat the oven. Preheat your oven to 400°F and lightly grease a 9×13-inch baking dish to ensure a smooth release of your casserole. Prepare the pasta base. Add the cubed chicken, cooked pasta, marinara sauce, chicken broth, minced garlic, and a blend of your favorite seasonings to the greased dish. Stir everything together so the flavors meld. Cover with aluminum foil and bake in your preheated oven for 25 minutes.

Step 2: Make the topping. While the casserole bakes, melt the butter in a medium skillet. Add the gluten-free breadcrumbs, garlic powder, onion powder, Italian seasoning, and a pinch of salt. Toast the breadcrumbs in the skillet until they’re golden and fragrant, creating a flavorful topping.

Step 3: Top the casserole. After 25 minutes, remove the casserole from the oven and uncover. Sprinkle the mozzarella cheese evenly over the top and then add the breadcrumb mixture, ensuring an even, crispy layer.

Step 4: Final bake. Return the casserole to the oven and bake for an additional 20-25 minutes, or until the cheese is melted, bubbly, and golden brown, and the chicken reaches an internal temperature of 165°F.

Step 5: Garnish and serve. Let the casserole cool for a few minutes before serving. For an extra touch of flavor, garnish the top of the casserole with freshly grated parmesan and a sprinkle of fresh basil.

Expert Tips

For an extra layer of flavor, drizzle of olive oil over the top of the casserole before baking to enhance the richness and help the breadcrumbs toast to golden perfection.
For perfectly cooked pasta, aim for al dente texture before baking.
Use leftover rotisserie chicken to save time.
To achieve an even golden topping, broil the casserole for 2-3 minutes at the end of baking.

What’s the best way to reheat this casserole?

Reheat this casserole in the oven at 350°F for 20-25 minutes, covered with foil to prevent drying out. For single portions, use the microwave and broil for 1-2 minutes to restore crispiness.

Crushed gluten-free crackers, cornflakes, or even crushed pork rinds work great for a crispy topping.
