Meatball Sliders Ingredients
- Ground beef – This is the base for your meatballs, so you want a good quality with a little bit of fat. 85/15 is a good choice.
- Onions – You only need two tablespoons to add some flavor. Make sure you saute them first. Raw onions won’t soften enough as they bake.
- Mozzarella cheese – You need Mozzarella twice, and in two different forms. Grab a block of Mozzarella (not string cheese) and cut some into small squares to add to your meatballs. Grate the rest for adding on top.
- Breadcrumbs – I prefer working with Panko because they don’t get as soggy.
- Seasoning – Garlic salt and oregano.
- 1 large egg – Whisk lightly before adding.
- Marinara sauce – A jar of marinara sauce is fine, or any kind of tomato based pasta sauce if that’s what you have on hand. You could also very easily make Marinara Sauce from scratch.
- Slider buns – You can find slider buns in packages of 8-12 in the bread section. Hawaiian rolls work too.
- Fresh parsley or basil – This is optional, but adds some color for a nice garnish.
How to Make Meatball Sliders
This meatballs sliders recipe is super simple. Make and bake the meatballs, then assemble the sliders. I have two options for assembly – a basic (yet still completely delicious) version and a deluxe version.
Form the meatballs. You want to be gentle with the ground beef because packing it together can create tough meatballs. Mix the ingredients together in a large bowl using a wooden spoon or clean hands. Evenly portion the meatballs and arrange them on a baking sheet.
Bake the meatballs. Bake them for about 15 minutes at 350°F. Sprinkle cheese on top and bake for a few more minutes so it can melt. While the meatballs are baking, heat the sauce over medium heat.
Heat the slider buns. Wrap the buns in foil and heat them in the oven while the meatballs are cooking.
Assembly. Split open a slider bun and place a meatball on the bottom half. Top with a little bit of warm marinara sauce and chopped fresh basil leaves and replace the top bun. Sprinkle some grated parmesan cheese and dried basil on top if desired.
For the deluxe version: Arrange the bottoms of the rolls close together (touching) in a baking dish or pan. Brush with melted garlic butter and lightly toast under the broiler. Remove from the oven and top with a meatball, Mozzarella, and sauce. Broil again just long enough to melt. Replace the tops of the rolls and brush with melted butter, sprinkle on grated Parmesan cheese and dried parsley or basil. Broil again for a couple of minutes or until tops are toasted.
You can. But they tend to be much smaller and don’t have as much flavor as making them from scratch. To make your sliders this way, just heat them with the marinara sauce.
You can prepare the meatballs ahead of time, and even bake them. Cool completely, then cover and refrigerate for up to 24 hours. Place them on a foil lined baking sheet, sprinkle on the shredded cheese, and heat for 5-10 minutes at 350℉ or until meatballs are hot and cheese is melted. Continue with assembly.
Or, you can prepare the meatballs, store them on the baking tray (covered tightly) and bake them the next day.
Absolutely! This recipe is easily adjustable for however many meatballs you need. Double or triple the recipe using the adjustable slider in the recipe card below. Keep in mind you may have to bake the meatballs in batches.
- Spicy – Add red pepper flakes to the marinara as it simmers to add some heat. You can also add red pepper flakes to the meatball mixture.
- Deluxe – Use a mixture of Italian sausage and ground beef and add a couple of minced garlic cloves. Brush the tops of the rolls with melted butter and sprinkle on fresh grated Parmesan, a pinch of garlic salt, and fresh chopped parsley. Broil for a minute or two to toast.
- Kid Friendly – Use your favorite spaghetti sauce instead of marinara. It tends to be more smooth and kids don’t usually like chunkier sauces.
- Brush the insides of the rolls with melted garlic butter and toast lightly.
- Make them extra fancy by adding a party toothpick and a small leaf of fresh basil to the top.
If you’re serving these sliders as an appetizer, make it an Italian theme! Serve with some garlic breadsticks, caesar salad, and an antipasto platter. Caprese Skewers would make a great addition to the spread.
Storage and Reheating
Storage: Store meatballs in an airtight container in the fridge. Assembled sliders can be stored and reheated, but the bread will get a little soggy from the sauce.
Freezing: Leftover meatballs are great for freezing to have on hand anytime you need them. Cool completely, then flash fresh by arranging them on a parchment paper lined baking sheet and popping it into the freezer for about an hour. Once they are solid, you can toss them into a resealable freezer bag and freeze for up to 6 months.
Reheating: Fresh or frozen, you can just toss the meatballs into a bubbling saucepan of marinara and they will heat up and stay moist. Or you can microwave them.
- Use an ice cream scoop for perfectly portioned meatballs.
- Or, for evenly sized meatballs, weigh each piece on a kitchen scale. Mine were about 2.5 ounces.
- Don’t crowd the meatballs on the baking sheet. Leave at least an inch all around each one to promote even cooking.
- For best results, preheat your oven.
- Serve extra marinara sauce on the side for dipping.
- Use small slices of mozzarella instead of shredded for the topping if you want easier application and more coverage.
