Ingredients

• For the Meatballs: 1 ½ lbs (680 g) ground beef (80/20), ½ lb (225 g) ground pork, ½ cup (50 g) Italian breadcrumbs, ⅓ cup (30 g) grated Parmesan cheese, 2 large eggs, ¼ cup (60 ml) milk, 3 cloves garlic (minced), 2 tbsp fresh parsley (chopped, or 2 tsp dried), 1 ½ tsp salt, ½ tsp black pepper, 1 tsp dried oregano, ½ tsp crushed red pepper flakes (optional)
• For the Marinara Sauce: 2 (24 oz / 680 g) jars marinara sauce (or 6 cups homemade), 1 small onion (finely chopped), 2 cloves garlic (minced), 1 tbsp olive oil, 1 tsp dried basil, 1 tsp dried oregano, salt and pepper to taste

Instructions

Step 1: Prepare the Meatball Mixture

In a large mixing bowl, combine ground beef, ground pork, breadcrumbs, Parmesan, eggs, milk, garlic, parsley, salt, pepper, oregano, and red pepper flakes. Mix gently until just combined—do not overmix to keep the meatballs tender.

Step 2: Shape the Meatballs

Shape mixture into 1½-inch (4 cm) balls and place on a parchment-lined baking sheet. You should have about 30 meatballs.

Step 3: Optional Broiling Step

For firmer meatballs with extra flavor, broil on high for 3–4 minutes, turning once, until lightly browned. This step can be skipped if you prefer to skip the oven entirely.

Step 4: Sauté the Aromatics

In a skillet over medium heat, warm olive oil. Add onion and garlic; sauté 3–4 minutes until softened and fragrant.

Step 5: Prepare the Slow Cooker

Add sautéed onion and garlic, marinara sauce, basil, oregano, salt, and pepper to the slow cooker. Stir to combine.

Step 6: Add the Meatballs

Gently nestle the meatballs into the sauce in the slow cooker, making sure they are mostly submerged.

Step 7: Slow Cook

Cover and cook on LOW for 4 hours (or HIGH for 2 hours), until meatballs are cooked through and reach an internal temperature of 160°F/71°C.

Step 8: Serve

Serve hot, garnished with extra Parmesan and parsley if desired. Offer toothpicks for appetizer-style serving or ladle over spaghetti for a main course.

Zusatztipps für die Zubereitung

For the most tender meatballs, avoid overworking the meat mixture—mix just until the ingredients are evenly distributed. If you have time, refrigerate the shaped meatballs for 30 minutes before cooking to help them hold their shape better. The optional broiling step is worth it if you want a deeper, caramelized flavor and slightly firmer texture, but it's perfectly fine to skip if you're short on time. When adding meatballs to the slow cooker, arrange them in a single layer if possible, though some stacking is fine. Stir gently halfway through cooking to ensure even coverage with sauce.

Varianten und Anpassungen

This recipe is wonderfully adaptable to different dietary needs and preferences. For a lighter version, substitute ground turkey or chicken for the beef and pork—just be aware that poultry can dry out more easily, so consider adding an extra tablespoon of milk to the mixture. To make it gluten-free, use gluten-free breadcrumbs and check that your marinara sauce is certified gluten-free. For a spicier kick, increase the crushed red pepper flakes or add a pinch of cayenne to the meatball mixture. You can also experiment with the cheese by using Pecorino Romano instead of Parmesan for a sharper flavor. If you prefer homemade marinara, simply blend canned San Marzano tomatoes with garlic, olive oil, basil, and oregano for a fresher taste.

Serviervorschläge

These meatballs shine in multiple serving scenarios. For appetizers, keep them warm in the slow cooker on the 'warm' setting and provide toothpicks for easy grabbing. As a main dish, serve over al dente spaghetti, penne, or your favorite pasta, topped with freshly grated Parmesan and torn basil leaves. For a heartier meal, nestle them into toasted sub rolls with melted mozzarella for meatball subs. Pair with garlic bread, a crisp green salad, and a medium-bodied red wine like Chianti or Sangiovese. Leftovers can be stored in an airtight container in the fridge for up to 4 days or frozen for up to 3 months—simply reheat gently on the stovetop or in the microwave.
