Step-by-Step: Skinny Chicken Parmesan Casserole

Step 1: Cook the Pasta

Begin by bringing a large pot of salted water to a boil. Add the whole grain penne pasta and cook according to package instructions until al dente. Drain and set aside.

Step 2: Prepare the Chicken

While the pasta is cooking, heat a non-stick skillet over medium heat. Add the bite-sized chicken pieces and cook until they are no longer pink in the center, approximately 5-7 minutes. Season with salt and pepper to taste.

Step 3: Mix the Ingredients

In a large mixing bowl, combine the cooked pasta, marinara sauce, diced tomatoes (if using), and the cooked chicken. Stir until everything is well-coated and evenly distributed.

Step 4: Layer the Casserole

Transfer the pasta mixture into a greased 9×13-inch baking dish. Spread it out evenly.

Step 5: Add the Cheese Topping

Sprinkle the shredded skim mozzarella cheese evenly over the top of the pasta mixture. Then, in a small bowl, combine the Panko breadcrumbs, grated Parmesan cheese, and Italian seasoning. Sprinkle this mixture over the cheese layer for added crunch.

Step 6: Bake

Preheat your oven to 375°F (190°C). Bake the casserole for about 25-30 minutes, or until the cheese is bubbly and the top is golden brown.

Step 7: Serve and Enjoy

Once baked, remove the casserole from the oven and let it sit for a few minutes before serving. This Skinny Chicken Parmesan Casserole is best enjoyed hot and fresh from the oven, garnished with fresh herbs if desired.

Texture-Safe Substitutions

• Gluten-Free Pasta: Swap the whole grain penne for gluten-free pasta if you need to avoid gluten.
• Vegan Cheese: Use a plant-based cheese alternative to make this casserole vegan.
• Ground Turkey or Tofu: Substitute the chicken with ground turkey or cubed tofu for a different protein option.
• Vegetable Add-Ins: Feel free to add in veggies like spinach, zucchini, or bell peppers for extra nutrition and flavor.

Notes from the Test Kitchen

• For a bit more flavor, consider marinating the chicken in Italian dressing for an hour before cooking.
• If you prefer a spicier dish, add red pepper flakes to the marinara sauce.
• This casserole can be assembled ahead of time and stored in the refrigerator for up to a day before baking.
• For a more robust flavor, try using homemade marinara sauce instead of store-bought.

Keep It Fresh: Storage Guide

The Skinny Chicken Parmesan Casserole can be stored in an airtight container in the refrigerator for up to 4 days. Reheat in the microwave or oven until warmed through. If you want to freeze it, allow the casserole to cool completely before covering and storing in a freezer-safe container. It can be frozen for up to 3 months. Thaw in the refrigerator overnight before reheating.

Ask the Chef

Can I make this casserole without chicken?

Absolutely! You can easily substitute the chicken with any plant-based protein or even skip the protein altogether for a delicious vegetarian dish.

What can I serve with this casserole?

This casserole pairs beautifully with a simple green salad or steamed vegetables for a complete meal. Garlic bread is also a great side if you’re looking to indulge a bit more.

Can I use regular pasta instead of whole grain?

Yes, you can use regular pasta if you prefer. However, using whole grain pasta adds extra fiber and nutrients, making it a healthier option.

How do I know when the casserole is done baking?

The casserole is done when the cheese is melted, bubbly, and the top is golden brown. You can also use a food thermometer; it should read at least 165°F (74°C) for the chicken to be fully cooked.
