About this recipe

This baked meatballs recipe blends ground beef and pork sausage with breadcrumbs, milk, eggs, Parmesan, and Italian seasoning. They bake quickly at a high temperature to set the exterior, then finish in a baking dish with marinara and mozzarella. The result is tender, flavorful meatballs with melty cheese — perfect for weeknight dinners, meal prep, or parties.

Use store-bought or homemade marinara and adjust the herbs and cheese to your taste. These meatballs are equally comfortable served over spaghetti, in a sub roll, or alongside roasted vegetables.

What’s in them

The ingredient list is short and pantry-friendly. Each component plays a role in flavor, texture, or structure:

Ingredients for meatballs.
  • Ground beef — provides beefy flavor and richness.
  • Ground pork sausage — adds moisture and seasoning; use mild or spicy depending on preference.
  • Bread crumbs — bind the mixture and give a tender texture.
  • Milk — soaks the breadcrumbs to keep meatballs moist.
  • Eggs — help bind the mixture and add richness.
  • Fresh parsley — brightens the flavor.
  • Freshly grated Parmesan — nutty, savory depth.
  • Italian seasoning, salt, and pepper — basic seasoning to round out the flavors.
  • Marinara sauce — coats the meatballs and adds bright tomato flavor.
  • Mozzarella — melted on top for a gooey finish.

How to make these

(Full ingredient proportions and times are listed below in the recipe card.)

A bunch of ingredients to make meatballs.
  1. Preheat the oven to 425°F and line a rimmed baking sheet with parchment paper.
  2. Combine the milk and breadcrumbs in a small bowl and let them sit until the crumbs are softened into a paste.
  3. Add the ground beef, pork sausage, eggs, Parmesan, parsley, Italian seasoning, salt, and pepper to a large bowl. Add the breadcrumb mixture.
  4. Gently mix by hand until just combined — don’t overwork the meat.
  5. Portion the mixture into tablespoon-sized balls using a scoop or spoon, and roll them into uniform shapes. Place on the prepared baking sheet.
  6. Bake for 10–12 minutes, or until an instant-read thermometer registers 160°F (71°C).
  7. Spread about 1 cup of marinara in the bottom of a 9×13-inch baking dish. Transfer the baked meatballs into the dish, add the remaining sauce, and gently toss to coat.
  8. Sprinkle shredded mozzarella over the top and bake at 350°F, uncovered, about 10 minutes, until the cheese is melted and bubbly.

Expert tips

Small technique changes make a big difference:

  • Choose meats with some fat for juicier meatballs. A mix of beef and pork sausage gives good flavor.
  • Soaking the breadcrumbs in milk prevents dry meatballs and yields a tender texture.
  • Handle the mixture gently — over-mixing can make meatballs dense.
  • Make the meatballs the same size so they cook evenly; a tablespoon scoop works well.
  • Shorten bake time at high heat to set the outside, then finish in sauce so they stay moist.
  • Air-fryer option: cook at 425°F for 10–12 minutes for a slightly crisp exterior.

How do you store these?

In the fridge

Store cooled meatballs in an airtight container in the refrigerator for up to 4 days. Reheat covered in the oven or gently in a microwave.

In the freezer

Freeze baked meatballs on a sheet tray until firm, then transfer to a freezer-safe container or bag for up to 3 months. Thaw overnight in the refrigerator and reheat in the oven or microwave.

Variations and substitutions

  • Use ground turkey, chicken, or lamb instead of beef or pork.
  • Swap breadcrumbs for crushed crackers, oats, or cornmeal for a different texture.
  • Try different cheeses: cheddar, gouda, or a sprinkle of feta change the flavor profile.
  • Replace milk with buttermilk, yogurt, or a plant-based milk to suit dietary needs.

Vegetarian options

Make vegetarian meatballs with a plant-based ground product or a mixture of cooked lentils, breadcrumbs, grated vegetables, and seasonings. Use a flax egg (1 tbsp ground flaxseed + 3 tbsp water, set 5 minutes) instead of eggs and a vegan Parmesan or nutritional yeast in place of cheese.

How to Serve Baked Meatballs

Baked meatballs are versatile:

  • Main dish: Serve with pasta, roasted vegetables, or a salad.
  • Sandwiches: Make meatball subs on a roll with extra marinara and melted mozzarella.
  • Appetizers: Arrange on a platter with toothpicks and a bowl of sauce for dipping.
  • Pizza topping: Slice meatballs and add to homemade pizza before baking.
  • Soup: Add warmed baked meatballs to a vegetable or broth-based soup for a hearty meal.

Frequently asked questions

Can I make these ahead of time and freeze them?
