Slow Cooker Juicy Meatballs (Printer-friendly)

Tender meatballs cooked slowly in a flavorful tomato and herb sauce, ideal for gatherings.

# 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

→ Tomato 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

# Directions:

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 which can result in tough meatballs.
02 - Shape the mixture into uniform golf ball-sized meatballs approximately 1.5 inches in diameter, yielding about 30-32 meatballs total.
03 - For enhanced flavor development, 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. Alternatively, skip this step for softer texture.
04 - In the bottom of your slow cooker, add olive oil, diced onion, and tomato paste. Stir to combine thoroughly. Pour in crushed tomatoes, dried Italian herbs, and sugar. Season with salt and pepper to taste.
05 - Gently nestle the prepared meatballs into the sauce in a single layer. Spoon sauce over the tops to ensure partial coverage.
06 - Cover the slow cooker and cook on LOW setting for 4-5 hours, until meatballs are cooked through and tender.
07 - Transfer to serving dish. Serve warm directly from the slow cooker with toothpicks for appetizer presentation or over cooked pasta for a main course. Garnish with additional Parmesan and fresh parsley.

# Expert Advice:

01 -
  • They cook hands-off in the slow cooker, leaving you free to do literally anything else.
  • The long, gentle heat makes the meatballs impossibly tender and keeps them warm for hours without drying out.
  • One batch feeds a crowd and tastes even better when made a day ahead.
02 -
  • Don't overmix the meat mixture—overmixing develops gluten in the breadcrumbs and makes the meatballs tough and rubbery rather than tender.
  • The slow cooker won't brown the outsides, so searing them beforehand adds textural contrast and deeper flavor (though it's optional if you prefer them softer).
  • Taste the sauce before serving and adjust seasoning—slow cookers don't reduce liquids the way stovetop cooking does, so flavors stay mild unless you season boldly.
03 -
  • Undercook the meatballs slightly before the slow cooker if you sear them, since they'll cook further during the long, gentle heat.
  • Keep the slow cooker on LOW rather than HIGH—the long, slow temperature keeps them tender instead of rubbery or shrunken.
