Slow Cooker Juicy Meatballs (Printable Version)

Tender meatballs simmered in a rich tomato sauce, slow-cooked for deep, savory flavor and ease.

# Components:

→ 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 mixing bowl, combine ground beef, breadcrumbs, Parmesan cheese, eggs, milk, minced garlic, fresh parsley, dried oregano, salt, and black pepper. Mix gently with your hands until just combined, being careful not to overwork the mixture as this results in dense meatballs.
02 - Shape the mixture into uniform balls approximately 1.5 inches in diameter, roughly golf ball-sized. You should produce approximately 30 to 32 meatballs. Place on a plate or baking sheet.
03 - For enhanced flavor development, heat a large skillet over medium-high heat with a light coating of oil. Working in batches to avoid crowding, sear meatballs until browned on all sides, approximately 3 minutes per batch. Transfer browned meatballs to a clean plate. This step can be omitted for a softer texture.
04 - In the bottom of your slow cooker, add olive oil, diced onion, and tomato paste. Stir until well combined. Pour in the crushed tomatoes, dried Italian herbs blend, and sugar. Season with salt and black pepper to taste. Stir to incorporate all ingredients.
05 - Gently nestle the prepared meatballs into the tomato sauce in a single layer. Spoon additional sauce over the tops of the meatballs to partially submerge them.
06 - Cover the slow cooker and cook on the low setting for 4 to 5 hours, until meatballs are cooked through and tender. Stir gently halfway through cooking if desired.
07 - Transfer meatballs and sauce to a serving dish, keeping the slow cooker warm on low if serving over an extended period. Present with toothpicks as appetizers or serve over cooked pasta as a main course. Garnish with additional Parmesan cheese and fresh parsley.

# Expert Tips:

01 -
  • They stay warm and glossy for hours, which means you can actually enjoy your own party instead of playing kitchen relay.
  • The sauce gets silkier the longer it simmers, creating this umami depth that tastes like you fussed for days.
  • You can prep everything the night before and let the slow cooker do the heavy lifting while you handle everything else.
02 -
  • Never skip the gentle mixing step—the moment you feel resistance as you stir, stop immediately, or your meatballs will become dense rather than tender and yielding.
  • If you brown the meatballs first, they develop a caramelized exterior that adds complexity, but leaving them raw gives you lighter, softer results depending on your mood.
03 -
  • An 80/20 ground beef blend is the sweet spot—it has enough fat to stay juicy without turning greasy once the meatballs have cooked for hours.
  • If your sauce seems thin after cooking, remove the slow cooker insert and simmer it on the stovetop for 5 to 10 minutes to reduce it down to a glossy coating.
