Tender meatballs cooked slowly in a flavorful tomato sauce, ideal for easy, crowd-pleasing 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 Cook:

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, avoiding overmixing.
02 - Form the mixture into golf ball-sized meatballs approximately 1.5 inches in diameter, yielding about 30-32 pieces.
03 - Heat a large skillet over medium-high heat with a splash of oil. Sear meatballs in batches until browned on all sides, approximately 3 minutes per batch. Transfer to a plate. Skip this step for softer meatballs.
04 - In the bottom of the slow cooker, add olive oil, diced onion, and tomato paste. Stir to combine. Pour in crushed tomatoes, Italian herbs, and sugar. Season with salt and pepper to taste.
05 - Gently nestle meatballs into the sauce in a single layer. Spoon sauce over the tops to cover.
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 as appetizers or over cooked pasta as a main dish. Garnish with additional Parmesan cheese and fresh parsley.

# Expert Advice:

01 -
  • You can prep everything in the morning and come home to dinner already waiting, which feels like getting an extra hour back in your day.
  • The slow cooker does the heavy lifting—no babysitting, no stress, just tender meatballs that somehow taste even better than stovetop versions.
  • These work equally well as appetizers at a party or spooned over pasta when you want something substantial and comforting.
02 -
  • Overmixing the meatball mixture is the number-one reason people end up with tough, dense results—treat it like you're folding delicate ingredients, not making cement.
  • Browning the meatballs is optional but worth it if you have even fifteen minutes; it creates a caramelized crust that survives the slow cooker and adds serious depth to the final dish.
03 -
  • Don't skip the sugar—even a teaspoon balances tomato acidity in a way that makes people pause and ask what you did differently, and the answer is simply trusting the science.
  • If you brown the meatballs beforehand, let the skillet cool slightly before adding the sauce ingredients; it prevents steam eruptions and gives you better control of the final taste.
