Ingredients
Scale
- 24 frozen small or regular-sized meatballs
- 3 cups marinara sauce
- 12 slider buns (soft and fresh, Hawaiian rolls recommended)
- 12 slices or about 8 ounces shredded mozzarella cheese
- 4 tablespoons melted butter
- 1 teaspoon garlic powder
- 1 teaspoon dried Italian seasoning (optional)
- Handful of fresh basil or parsley, chopped (for garnish)
Instructions
- Spray the inside of your crockpot with non-stick cooking spray or lightly oil it.
- Place about 24 frozen meatballs evenly in the bottom of the crockpot.
- Pour 3 cups of marinara sauce over the meatballs, coating them well. Stir gently if needed.
- Sprinkle 1 teaspoon garlic powder and 1 teaspoon Italian seasoning over the sauce.
- Cover and cook on low for 4 hours or high for 2 hours until meatballs are heated through and tender.
- About 30 minutes before serving, preheat oven to 350°F (175°C).
- Slice the slider buns horizontally but keep them connected like pull-apart bread.
- Brush melted butter over the cut sides of the buns.
- Remove meatballs from crockpot using tongs and place evenly on the bottom halves of the buns.
- Spoon extra sauce over the meatballs to keep them juicy.
- Layer mozzarella slices or shredded cheese evenly over the meatballs.
- Place the assembled sliders on a baking sheet and bake for 10-12 minutes until cheese is melted and buns are toasted.
- Sprinkle chopped fresh basil or parsley on top, cut sliders apart, and serve warm.
Notes
Use frozen meatballs straight from the freezer for best results. Brush buns with butter before baking to avoid sogginess and add richness. Add mozzarella cheese only before baking to keep it melty and not rubbery. For gluten-free, use gluten-free buns; for dairy-free, use vegan cheese and substitute butter with olive oil. Sliders can be prepped ahead and refrigerated before baking, adding extra baking time if cold.
