Ingredients
  

  • Mini rolls or slider buns: About 12–16, preferably soft dinner rolls or mini hoagie buns.
  • Meatballs: 24–32 small meatballs (store-bought frozen or homemade), about 1-inch each.
  • Marinara sauce: 2 cups, your favorite jarred or homemade.
  • Mozzarella cheese: 2 cups shredded, or sliced provolone.
  • Parmesan: 1/3 cup grated, for extra savory bite.
  • Butter: 3 tablespoons, melted.
  • Garlic: 2 cloves minced, or 1 teaspoon garlic powder.
  • Italian seasoning: 1 teaspoon.
  • Fresh parsley or basil: For garnish.
  • Optional heat: Red pepper flakes.
  • Optional add-ons: Sautéed onions and peppers, pickled jalapeños, or a swipe of pesto.

Method
 

  1. Warm the sauce and meatballs: Simmer meatballs in marinara over medium-low heat for 10–12 minutes (or according to package directions) until heated through and coated.
  2. Prep the rolls: Preheat oven to 375°F (190°C). Split the mini rolls, keeping the bottoms and tops connected if using a pull-apart sheet. Place on a parchment-lined baking sheet, cut side up.
  3. Garlic butter base: Mix melted butter, garlic, and Italian seasoning. Brush half over the cut sides of the rolls.
  4. Cheese layer: Sprinkle half the mozzarella over the bottom halves. This helps create a melty “glue” for the meatballs.
  5. Add meatballs: Place 1–2 meatballs on each roll bottom, depending on size. Spoon a little extra sauce on top—avoid drenching to prevent sogginess.
  6. Top and finish: Add remaining mozzarella and the Parmesan. Close with the top buns. Brush the remaining garlic butter over the tops. Sprinkle a pinch of red pepper flakes if you like heat.
  7. Bake: Cover loosely with foil and bake 10 minutes. Remove foil and bake 5–8 more minutes until the cheese is melted and the tops are golden.
  8. Garnish and serve: Let rest 3–5 minutes. Scatter chopped parsley or basil over the top. Slice into individual bites if using pull-apart rolls and serve warm.
  9. Air fryer option: Assemble in batches in a lined basket at 350°F (175°C) for 5–7 minutes until toasty and melty.
