Plus, it’s basically a dump-and-bake situation. Assemble in minutes, pop it in the oven, and dinner practically makes itself. Weeknight magic, I tell you.

What Ingredients are in Heartwarming Chicken Parmesan Casserole?

This Chicken Parmesan Casserole combines all the flavors of traditional chicken parm but in a simplified, no-fuss version that’s perfect for busy weeknights.

The ingredients list might look long at first glance, but don’t worry—these are mostly pantry and fridge staples that create layers of Italian-inspired goodness. Each component plays an important role in building that classic flavor profile we all know and love.

• 2 tablespoons olive oil
• 2 garlic cloves, minced
• Red pepper flakes, to taste
• 6 boneless skinless chicken breast halves (5-6 ounces each)
• 2 cups marinara sauce
• 1/4 cup fresh basil, chopped
• 2 cups mozzarella cheese, shredded
• 1 cup parmesan cheese, grated
• 1 package (5 ounces) garlic-flavored croutons

For the best results, I recommend using a high-quality marinara sauce since it provides so much of the flavor foundation.

And while pre-shredded cheese is convenient, freshly grated cheese melts more smoothly.

As for the chicken, you could substitute chicken tenders or even chicken thighs if you prefer darker meat—just adjust the cooking time accordingly.

The garlic-flavored croutons are the secret weapon here, providing that crispy topping without having to bread and fry the chicken. Can we talk about how genius that shortcut is?

How to Make this Heartwarming Chicken Parmesan Casserole

Making this chicken parmesan casserole couldn’t be easier—it’s truly a one-pan wonder that delivers all that classic chicken parm flavor without the fuss of breading and frying.

Start by preheating your oven to 350 degrees, then grab a 9×13 baking pan and drizzle it with 2 tablespoons of olive oil. Add the 2 minced garlic cloves and a sprinkle of red pepper flakes (adjust according to your heat preference), spreading them evenly across the bottom of the pan. This creates an aromatic base that infuses into the chicken as it cooks.

Next, arrange your 6 boneless skinless chicken breasts in the pan, nestling them into that garlicky oil. Pour 2 cups of marinara sauce over the chicken, making sure each piece gets some saucy love. Sprinkle the 1/4 cup of fresh chopped basil over the sauce—those little flecks of green don’t just look pretty, they add a wonderful freshness to the dish.

Now comes the cheese layer: add half of your 2 cups of shredded mozzarella and half of the 1 cup of grated parmesan. The real genius move? Dump that entire 5-ounce package of garlic-flavored croutons right on top. Those croutons are the secret shortcut that gives you that crispy chicken parm texture without any breading station mess.

Finish with the remaining cheese, creating a melty blanket that will turn golden brown in the oven.

Pop the casserole into your preheated oven and bake for 45-55 minutes, or until the chicken is fully cooked through. The timing may vary depending on the thickness of your chicken breasts, so if you have a meat thermometer, you’re looking for an internal temperature of 165°F.

Once it’s done, resist the urge to dig in right away—let the casserole stand for about 10 minutes before serving. This resting period allows the juices to redistribute through the chicken and gives the sauce a chance to settle down from its bubbly state. Trust me, those few minutes of patience are worth it for juicy chicken and a casserole that holds together when you serve it.

Heartwarming Chicken Parmesan Casserole Substitutions and Variations

While the classic chicken parmesan casserole recipe is already a crowd-pleaser, you can easily adapt it to suit your dietary needs or whatever ingredients you have on hand.

I often swap in turkey cutlets when I’m watching calories, or use gluten-free croutons for my celiac friends. No mozzarella? Try provolone or fontina instead.

The marinara sauce is totally customizable too—sometimes I add mushrooms, spinach, or even a splash of cream for something richer.

Got picky eaters? You can dial back the garlic or red pepper flakes. Trust me, this flexible dish never disappoints, no matter how you tweak it.

What to Serve with Heartwarming Chicken Parmesan Casserole

When it comes to serving the perfect side dish with your heartwarming chicken parmesan casserole, you’ll want options that complement rather than compete with those rich Italian flavors.

I love pairing this casserole with a crisp green salad dressed simply with lemon and olive oil. The brightness cuts through the cheesy goodness perfectly.

Garlic bread is non-negotiable in my house—something to soak up that marinara sauce, right?

For veggies, roasted asparagus or sautéed green beans with a touch of lemon zest work wonders.

And if you’re extra hungry? A small portion of buttered pasta never hurt anyone.

Notes

For best results, use freshly grated cheese as it melts more smoothly than pre-shredded varieties. If you prefer darker meat, you can substitute chicken thighs for the breasts, but you may need to adjust cooking time accordingly. The casserole can be assembled ahead of time and refrigerated for up to 24 hours before baking – just add 5-10 minutes to the cooking time if baking from cold.

Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat individual portions in the microwave or warm the entire casserole, covered with foil, in a 325°F oven until heated through.
