Follow these simple steps to make your Crock-Pot Chicken Parmesan an incredible hit:

1. Prepare the Chicken: Season the chicken breasts with salt, pepper, Italian seasoning, and garlic powder on both sides.

2. Add Sauce: Place the seasoned chicken breasts in the bottom of the Crock-Pot. Pour marinara sauce over the top, ensuring the chicken is well coated.

3. Cook Chicken: Cover the slow cooker with the lid and set it to low for 4 to 6 hours or high for 2 to 3 hours. Cook until the chicken is tender and fully cooked.

4. Add Cheese: About 30 minutes before serving, sprinkle shredded mozzarella and grated Parmesan cheese on top of the chicken. Drizzle with olive oil to enhance flavor.

5. Toast Breadcrumbs: (Optional) While the cheese is melting, you can toast the breadcrumbs in a pan over medium heat for 2 to 3 minutes until golden brown (this adds crunch).

6. Serve with Breadcrumbs: Once the cheese is melted, sprinkle the toasted breadcrumbs over the top for added texture and serve.

Each step ensures a delightful outcome, bringing the wonderful flavors of chicken Parmesan into your home effortlessly.
