Spaghetti and Meatball Sliders are a fun twist on two favorites, transforming dinner into an appetizer with handheld spaghetti sandwiches packed with homemade meatballs, tangy marinara sauce, and melted cheese, all nestled between soft Hawaiian rolls. This easy concoction makes enjoying spaghetti and meatballs as simple as picking them up with your hands, no fork required!
Preheat the oven to 375℉. Spray a 9x13 inch baking dish with cooking spray and set aside. Line a sheet tray with parchment paper.
In a large bowl, mix together the ground beef, breadcrumbs, Parmesan cheese, egg, onion soup mix, garlic powder, oregano, and black pepper until combined. Do not overmix. Tip: Use your clean hands to mix for best results.
Divide the mixture into 12 portions and roll into balls. Place on the prepared sheet pan. Make sure the meatballs do not touch.
Bake the meatballs for 10 to 15 minutes until the internal temperature reaches 165℉.
While the meatballs are baking, place the cooked spaghetti noodles into a large mixing bowl with the marinara sauce and Parmesan cheese. Stir to combine.
Slice the rolls in half lengthwise. Place the bottom, cut side up into the prepared baking dish.
Add the spaghetti on top of the rolls.
Place one meatball onto each slider.
Add the mozzarella on top of the meatballs.
Top with the top of the rolls.
In a small bowl, stir together the butter, Italian seasoning, garlic powder, and onion powder. Brush on the top of the rolls. Make sure to use it all.
Cover with nonstick aluminum foil or spray a large piece of foil with cooking spray and cover the sliders. Make sure the foil doesn't touch the tops.
Bake for 20 minutes, remove the foil and bake for an additional 4 to 5 minutes or until the tops of the rolls are browned.
Allow to cool for 10 minutes, then slice and serve.
