FAQs

Can you cook raw meatballs directly in the sauce?

Yes. You can form raw meatballs and simmer them gently in sauce until cooked. Pre-baking gives a bit more texture and helps them hold their shape while still absorbing sauce flavors.

How do I know when meatballs are done?

They are done when the internal temperature reaches 160°F (71°C). A meat thermometer gives the most reliable result; otherwise cut one open to ensure there’s no pink in the center.

What grade of ground beef is best for meatballs?

An 80/20 mix (80% lean, 20% fat) provides good flavor and keeps meatballs juicy without being overly greasy.

Ingredients

For the meatballs:

  • 2 lb ground beef
  • 1 medium onion, chopped
  • 1 cup breadcrumbs
  • 1 egg
  • 1 teaspoon oregano
  • 1 teaspoon garlic powder
  • 1/2 teaspoon thyme leaves
  • 3/4 teaspoon black pepper
  • 1 teaspoon salt, or to taste
  • 1/2 cup fresh parsley, chopped

For the sauce:

  • 1 jar marinara sauce
  • 1 cup shredded mozzarella cheese
  • 1/2 cup grated parmesan cheese

Instructions

  1. Preheat oven to 425°F and line a large baking sheet with aluminum foil.
  2. In a large bowl combine onion, breadcrumbs, egg, herbs, spices, salt, and parsley. Mix well to distribute the seasonings.
  3. Add the ground beef to the seasoned mixture and gently combine until just incorporated. Do not overwork the meat to keep the meatballs tender.
  4. Using a two-tablespoon scoop or your hands, form evenly sized meatballs and arrange them on the prepared baking sheet. Leave space between each meatball for even browning.
  5. Bake for 15 minutes. The meatballs should be browned on the outside but not fully cooked through.
  6. Reduce oven temperature to 350°F. Pour the marinara into a 13×9-inch baking dish and add the partially baked meatballs, turning them gently to coat with sauce.
  7. Sprinkle the top with mozzarella and parmesan cheese, then return the dish to the oven.
  8. Bake for another 15–20 minutes, or until the cheese is melted and the meatballs are cooked through (160°F internal temperature).

What variations can you make to these meatballs?

  • Swap the protein: use ground turkey, chicken, or a plant-based beef alternative for different flavors and textures.
  • Adjust the seasoning: add crushed red pepper for heat, Italian seasoning for depth, or fresh herbs for brightness.
  • Try different cheeses: mozzarella and parmesan are classic, but provolone, fontina, or a little feta can change the character of the dish.
  • Make it gluten-free: replace regular breadcrumbs with a gluten-free substitute or crushed crackers made from gluten-free ingredients.

Amira’s tips

  • Handle the meat gently when mixing. Overmixing makes meatballs dense and tough.
  • Line your baking sheet with foil for easier cleanup and to prevent sticking.
  • Space meatballs apart on the sheet so they brown evenly rather than steam.

Storage and reheating tip

Refrigerate leftovers in an airtight container for up to 3 days. For longer storage, freeze meatballs in sauce in a freezer-safe container for up to 3 months. Thaw overnight in the refrigerator before reheating.

To reheat, warm the meatballs in a 350°F oven for about 15 minutes or until heated through. Alternatively, reheat gently on the stovetop in a covered saucepan over medium-low heat.

How to Make Meatballs Ahead?

Prepare and shape the meatballs up to 24 hours ahead and store them covered in the refrigerator. Keep them chilled until you’re ready to bake. For best results, use fresh ground beef and assemble shortly before cooking when possible.

Perfect pairings: what to serve with

Serve over spaghetti or any pasta, alongside cheesy mashed potatoes, or make subs using soft rolls. These meatballs also pair well with a crisp green salad or roasted vegetables for a complete meal.
