Creating Baked Chicken Parm Sliders is straightforward if you follow these simple steps:

1. Preheat Oven: Preheat your oven to 375°F (190°C).
2. Prepare Chicken: Slice the chicken breasts into thin cutlets for quicker cooking.
3. Set Up Breading Station: In one bowl, whisk the egg. In another bowl, combine breadcrumbs, grated Parmesan cheese, garlic powder, Italian seasoning, salt, and pepper.
4. Bread the Chicken: Dip each chicken cutlet first into the egg, then into the breadcrumb mixture, ensuring full coverage.
5. Bake the Chicken: Place the breaded chicken on a baking sheet lined with parchment paper. Drizzle with olive oil and bake for about 20 minutes or until golden brown and cooked through.
6. Assemble Sliders: After baking, remove the chicken from the oven. In a baking dish, place the bottom halves of the slider buns. Layer each bun with a piece of chicken, a spoonful of marinara sauce, and a sprinkle of mozzarella cheese.
7. Top and Bake Again: Place the top halves of the buns on each slider. Drizzle with olive oil and bake for an additional 10-15 minutes, or until the cheese is bubbly and the buns are golden.
8. Garnish and Serve: Once baked, remove from the oven and let them rest for a few minutes. Garnish with fresh basil leaves if desired.

These steps will guide you in creating these incredible sliders effortlessly, ensuring a delightful meal for you and your loved ones.
