Mix the beef, breadcrumbs, egg, parmesan, garlic, oregano, salt and pepper gently with your hands until just combined. Roll into 12 even meatballs, about 4.5 cm (1 3/4 inches) wide. 2. **Bake the meatballs.** Bake for 15-18 minutes, until browned and the centre of a meatball reaches 71°C (160°F). Turn the oven down to 180°C (350°F). 3. **Warm in the sauce.** While the meatballs bake, warm the marinara in a saucepan over medium heat. Add the cooked meatballs, turn to coat and simmer gently for 5 minutes. Lift them onto a board and cut each one in half. 4. **Assemble.** Without pulling the rolls apart, slice the slab in half horizontally and set the bottom half in the baking dish. Scatter over half the mozzarella, arrange 2 meatball halves on each roll and spoon about 1 cup of the sauce over them. Top with the rest of the mozzarella and the parmesan, then replace the top half of the rolls. 5. **Bake and serve.** Mix the melted butter with the garlic powder and herbs and brush it over the tops. Cover with foil and bake for 10 minutes, then uncover and bake for 5-8 minutes more, until the cheese is melted and bubbling. Cut into 12 sliders, add basil if you like, and serve with the remaining warm sauce for dipping. ## Tips - Short on time? Use a batch of air fryer meatballs, or fully cooked frozen meatballs simmered in the sauce until they reach 74°C (165°F) in the centre. - Use low-moisture mozzarella, the firm kind sold in blocks or shredded. Fresh mozzarella in water releases liquid and makes the rolls soggy. - Halving the meatballs keeps them flat, so the sliders don't topple when you cut them apart. - Choose a thick marinara, or simmer a thin one for 10 minutes to reduce it before assembling. ## Variations - Chicken or turkey meatballs: use ground chicken or turkey and bake until they reach 74°C (165°F). - Spicy: add 1/2 tsp chili flakes to the meatball mix and a few slices of pickled hot peppers under the top layer of cheese. - Provolone: swap half the mozzarella for sliced provolone for a sharper flavour. ## Storage - Fridge: Refrigerate leftover sliders within 2 hours in an airtight container for up to 3 days. Meatballs in sauce keep for up to 4 days on their own. - Freezer: Freeze the meatballs in their sauce for up to 3 months. Thaw overnight in the fridge before assembling. - Reheat: Reheat covered with foil at 180°C (350°F) for 10-15 minutes, or microwave single sliders for 45-60 seconds, until hot through, 74°C (165°F). ## Nutrition per serving (estimate) | Calories | Protein | Carbohydrates | Fat | |---|---|---|---| | 550 | 35 g | 42 g | 27 g | ## Frequently asked questions ### Can I use frozen or store-bought meatballs for meatball sliders? Yes. Use 12 fully cooked meatballs about 4-5 cm wide, or 24 smaller ones. Simmer them in the marinara until the centre reaches 74°C (165°F), then halve and assemble as usual. ### How do I keep meatball sliders from getting soggy? Use a thick marinara and spoon only about 1 cup of it into the sliders, keeping the rest for dipping. A layer of low-moisture mozzarella on the bottom bun also acts as a barrier against the sauce. ### What temperature should meatballs be cooked to? Cook beef meatballs to 71°C (160°F) in the centre. Chicken or turkey meatballs need 74°C (165°F). Check the largest meatball with an instant-read thermometer. ### Can I make meatball sub sliders ahead of time? Make the meatballs in sauce up to 3 days ahead and refrigerate them. Reheat them in the sauce, then assemble the sliders just before baking so the rolls don't soak up too much sauce. ## Disclaimer - Nutrition information is an estimate based on the listed ingredients.
