Line a baking sheet with parchment paper and preheat oven to 400 degrees F.
Mix together ground chicken, onion, garlic, oregano (1/2 teaspoon), crushed red pepper (1/4 teaspoon), salt and pepper, 1/2 cup marinara sauce, and 1/4 cup Parmesan cheese in a bowl (for best results, mix with hands).
Place bread crumbs (1 cup) in a shallow bowl.
Form eight patties from the chicken mixture, and coat each in bread crumbs. Place on prepared baking sheet.
Drizzle the patties evenly with the olive oil. Bake at 400 degrees for 20 minutes.
Remove from oven, and turn broiler on high.
Spoon the remaining marinara sauce on each patty and top with a slice of mozzarella cheese. Sprinkle with remaining Parmesan and top each with fresh cracked pepper.
Broil for 3-5 minutes, or until cheese is bubbly and melted.
Serve on slider buns topped with fresh basil
This recipe makes enough for 8 sliders. I doubled it when I made it- I recommend doing this so you can freeze half for later!
To freeze for later: lay formed and bread crumb coated patties on a parchment covered baking sheet and place in freezer for at least 20 minutes to flash freeze. Once hardened, transfer to an airtight container or plastic bag and store in the freezer for up to six months. When you are ready to eat, arrange on a parchment covered baking sheet and defrost in the fridge for 24 hours before baking.
You can make these into normal "burger-size" patties as well- make four, instead of eight, and purchase larger buns.
