Slow Cooker Meatballs Tomato (Print Version)

Tender meatballs slowly cooked in rich tomato sauce, ideal for casual entertaining and easy meals.

# What You'll Need:

→ Meatballs

01 - 2 lbs ground beef (80/20 blend)
02 - 1/2 cup breadcrumbs
03 - 1/4 cup grated Parmesan cheese
04 - 2 large eggs
05 - 1/3 cup whole milk
06 - 3 cloves garlic, minced
07 - 1/4 cup fresh parsley, chopped
08 - 1 tsp dried oregano
09 - 1 tsp salt
10 - 1/2 tsp black pepper

→ Sauce

11 - 2 cans (28 oz each) crushed tomatoes
12 - 1 small onion, finely diced
13 - 2 tbsp tomato paste
14 - 1 tbsp olive oil
15 - 2 tsp dried Italian herbs blend
16 - 1 tsp sugar
17 - Salt and black pepper to taste

# How to Make It:

01 - In a large bowl, combine ground beef, breadcrumbs, Parmesan cheese, eggs, milk, minced garlic, parsley, oregano, salt, and pepper. Mix gently until just combined without overmixing to maintain tender texture.
02 - Shape the mixture into golf ball-sized meatballs approximately 1.5 inches in diameter, yielding about 30-32 meatballs.
03 - Heat a large skillet over medium-high heat with a splash of oil. Working in batches, sear meatballs until browned on all sides, approximately 3 minutes per batch. Transfer to a plate. This step enhances flavor but can be skipped for softer meatballs.
04 - In the bottom of the slow cooker, add olive oil, diced onion, and tomato paste. Stir to combine thoroughly. Pour in crushed tomatoes, Italian herbs, and sugar. Season with salt and pepper to taste.
05 - Gently nestle the meatballs into the sauce in a single layer. Spoon sauce over the tops to ensure coverage.
06 - Cover and cook on LOW setting for 4-5 hours until meatballs are cooked through and tender.
07 - Serve warm directly from the slow cooker with toothpicks for appetizers or over cooked pasta as a main dish. Garnish with extra Parmesan cheese and fresh parsley.

# Expert Advice:

01 -
  • They cook completely unattended while you handle everything else, and somehow taste better than meatballs you'd spent hours hovering over.
  • The slow cooker keeps them warm and juicy for hours, which means your guests can eat whenever they want, and you're not playing food temperature police.
  • One batch feeds a small army, making this the ultimate stress-free solution when entertaining feels like too much.
02 -
  • Don't overmix the meatball mixture or they'll become dense and rubbery—just combine until you don't see dry spots, then stop.
  • The slow cooker needs to be at least six quarts; anything smaller will crowd the meatballs and cause uneven cooking.
  • Searing the meatballs first genuinely improves the final flavor, even though the whole point is supposed to be hands-off cooking.
03 -
  • Keep your slow cooker on LOW, never HIGH—high heat toughens the meat and breaks down the texture you've worked to build.
  • Don't fill the slow cooker more than three-quarters full or the sauce will slosh and the meatballs won't cook evenly.
