1 lb boneless skinless chicken cut into bite-size pieces for easy cooking.
½ teaspoon garlic powder to bring a subtle kick.
2 cups shredded mozzarella cheese, divided for layering cheesy goodness.
½ cup grated Parmesan cheese, adds that classic salty tang.
1 cup Italian seasoned breadcrumbs for a crunchy finishing touch.
Kosher salt and freshly ground black pepper, to taste, cause seasoning9s gotta be just right.
Foil to tightly cover the baking dish for baking steps outside the pressure cooker.

The Exact Process From Start to Finish

Step 1: Preheat your oven to 425B0F. Lightly grease a 9x13-inch baking dish so nothing sticks when you bake.
Step 2: Pour the uncooked spaghetti noodles into the dish. Try to spread 9em out even for good coverage.
Step 3: Add marinara sauce and water. Stir gently so noodles get coated but you don9t mess up their placement too much.
Step 4: Distribute your chicken pieces all over noodles. Sprinkle garlic powder, salt, and pepper evenly on top for flavor.
Step 5: Add 1 cup mozzarella and all that Parmesan cheese over everything. Cover tightly with foil and bake 30 minutes so chicken can get tender while flavors mingle.
Step 6: Remove foil, stir pasta and chicken a bit to make sure it9s cooking even. Sprinkle last cup mozzarella and breadcrumbs on top. Bake uncovered 10-15 more minutes until golden, bubbly, and chicken9s done with a nice tender pull. Let it sit 5 minutes before serving.

Your Leftover Strategy Guide

Refrigerate: Store leftover chicken parm in an airtight container. It9ll last about 3-4 days. Reheat gently so mozzarella stays melty, but not rubbery.
Freeze: Portion out leftovers in freezer-safe containers or bags. Freeze up to 2 months. Thaw overnight in fridge before reheating to keep the tender pull.
Reheat Tips: For best results, reheat in oven or air fryer to refresh the breadcrumb topping. Microwave works too but might soften the crunch.
