Ingredients Overview for Hearty High Protein Chicken Parmesan Casserole
Here’s what you will need to whip up this comforting dish:
- Boneless, skinless chicken breasts: The star of our dish, these provide lean protein and a tender texture.
- Marinara sauce: This brings that rich, tangy flavor that pairs beautifully with the chicken and cheese.
- Mozzarella cheese: Creamy and melty, it’s a must-have for that gooey, cheesy goodness.
- Parmesan cheese: Adds a distinctive, nutty flavor that really elevates the dish.
- Italian seasoning: A medley of herbs that enhances all the flavors; I love a good sprinkle!
- Breadcrumbs: These give the casserole that lovely, crunchy topping.
- Olive oil: Used to drizzle on top for a bit of richness; you can swap with melted butter if you prefer.
- Spinach (optional): For a pop of color and extra nutrition; feel free to toss in some fresh or frozen.
How To Make Hearty High Protein Chicken Parmesan Casserole
Let’s break down the steps to create this delicious casserole!
1. Preheat your oven: Set it to 375°F (190°C) so it’s ready to go when your casserole is assembled.
2. Season and sear the chicken: Sprinkle Italian seasoning on both sides of the chicken breasts. In a skillet over medium heat, add a splash of olive oil and sear the chicken until it’s golden brown, about 5 minutes per side. It’s okay if it’s not cooked all the way through; we’ll finish it in the oven. Once done, slice it into bite-sized pieces.
3. Layer it up: Grab a baking dish and spread a thin layer of marinara sauce at the bottom. Now, layer half of the chicken pieces, followed by more marinara sauce, a generous amount of mozzarella cheese, and half the breadcrumbs. Repeat these layers until you use everything up.
4. Top it off: Finish with a layer of marinara and sprinkle on the rest of the mozzarella and Parmesan cheese. Don’t forget to drizzle olive oil over the top for that golden finish.
5. Bake: Pop the casserole in your preheated oven and bake for 25-30 minutes until it’s bubbly and the cheese is golden.
6. Rest and serve: Allow the casserole to rest for a few minutes before digging in. This helps everything settle!
Serving Suggestions
When it comes to serving this hearty high protein chicken Parmesan casserole, you can keep it simple or dress it up a bit. I love serving it alongside a fresh green salad drizzled with balsamic dressing. It adds a nice contrast to the richness of the casserole. You could also serve it with garlic bread or over a bed of pasta to really make a meal out of it.
