Whether you're hosting your first housewarming or celebrating a new chapter, these meatballs bring comfort and warmth to any occasion. The slow cooker does all the heavy lifting, allowing the flavors to meld beautifully over four hours while you set up, greet guests, and enjoy the celebration. The secret to their tender texture lies in gentle mixing and the milk-soaked breadcrumbs that keep each bite incredibly moist.

Ingredients

• For the Meatballs: 2 lbs (900 g) ground beef (80/20 blend preferred), 1/2 cup (50 g) breadcrumbs, 1/4 cup (25 g) grated Parmesan cheese, 2 large eggs, 1/3 cup (80 ml) whole milk, 3 cloves garlic minced, 1/4 cup (15 g) fresh parsley chopped (or 2 tsp dried), 1 tsp dried oregano, 1 tsp salt, 1/2 tsp black pepper
• For the Sauce: 2 cans (28 oz/800 g each) crushed tomatoes, 1 small onion finely diced, 2 tbsp tomato paste, 1 tbsp olive oil, 2 tsp dried Italian herbs (basil, oregano, thyme blend), 1 tsp sugar (optional, to balance acidity), salt and black pepper to taste

Instructions

Step 1: Prepare the Meatball Mixture

In a large bowl, combine ground beef, breadcrumbs, Parmesan, eggs, milk, garlic, parsley, oregano, salt, and pepper. Mix gently until just combined—do not overmix.

Step 2: Shape the Meatballs

Shape the mixture into golf ball-sized meatballs (about 1.5 inches in diameter). You should have around 30–32 meatballs.

Step 3: Optional Browning

Optional (for extra flavor): Heat a large skillet over medium-high heat with a splash of oil. Sear the meatballs in batches until browned on all sides, about 3 minutes per batch. Transfer to a plate. (Skip this step for softer meatballs.)

Step 4: Build the Sauce Base

In the bottom of your slow cooker, add olive oil, onion, and tomato paste. Stir to combine. Pour in crushed tomatoes, Italian herbs, and sugar. Season with salt and pepper.

Step 5: Add Meatballs to Sauce

Gently nestle the meatballs into the sauce in a single layer. Spoon a little sauce over the tops to cover.

Step 6: Slow Cook

Cover and cook on LOW for 4–5 hours, or until meatballs are cooked through and tender.

Step 7: Serve

Serve warm directly from the slow cooker with toothpicks for appetizers or over cooked pasta for a main dish.

Zusatztipps für die Zubereitung

For the most tender meatballs, avoid overmixing the meat mixture—this keeps the texture light and prevents them from becoming dense. If you have time, browning the meatballs before adding them to the slow cooker creates a deeper, caramelized flavor and slightly firmer exterior, though this step is entirely optional. The milk-soaked breadcrumbs act as a binder while keeping the meatballs incredibly moist throughout the long cooking time. Make sure your slow cooker is at least 6-quart capacity to comfortably fit all the meatballs in a single layer for even cooking.

Varianten und Anpassungen

Substitute ground pork or turkey for some or all of the beef for a different flavor profile. For a gluten-free version, use certified gluten-free breadcrumbs in place of regular breadcrumbs. You can also make these ahead by preparing the meatballs and sauce the night before, refrigerating them separately, and starting the slow cooker the next day. For extra richness, add a splash of heavy cream to the sauce during the last 30 minutes of cooking. If you prefer a spicier kick, mix in red pepper flakes or add diced jalapeños to the sauce.

Serviervorschläge

These versatile meatballs shine in multiple serving styles. For a housewarming party, keep them warm in the slow cooker and provide toothpicks for easy appetizer-style snacking. For a heartier main dish, serve over cooked spaghetti, penne, or your favorite pasta, and garnish with extra grated Parmesan and fresh parsley. They also make excellent meatball subs when nestled into crusty Italian rolls with melted mozzarella. Pair with a medium-bodied red wine like Chianti or Sangiovese to complement the rich tomato sauce and savory meat flavors.
