Preheat and Prepare
Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper or foil, then lightly brush it with olive oil.
Soak the Breadcrumbs
In a large bowl, combine the breadcrumbs and milk. Let them sit for 2–3 minutes to absorb the liquid.
Mix the Meatball Ingredients
Add ground beef, ground pork, eggs, garlic, parmesan, parsley, salt, pepper, and Italian seasonings into the bowl.
Use your hands to gently mix everything until just combined.
Shape the Meatballs
Use an ice cream scoop or spoon to portion equal-sized balls (about 1½ inches wide). Roll them gently between your palms.
Bake or Sear the Meatballs
Option 1: Bake
Place the meatballs evenly on your baking sheet. Brush the tops lightly with olive oil and bake for 18–20 minutes, or until browned and cooked through.
Option 2: Pan-Sear First
For extra flavor, heat 2 tablespoons olive oil in a skillet and brown the meatballs for about 2–3 minutes per side before transferring to the oven to finish baking.
Simmer in Sauce
While the meatballs cook, warm marinara sauce in a large skillet over medium heat. Once the meatballs are done, gently transfer them into the sauce. Simmer for 10–15 minutes so the flavors meld beautifully.
Serve and Enjoy
Top with grated parmesan cheese and extra fresh parsley. Serve over spaghetti, in sandwiches, or straight from the pot.
