These slow cooker meatballs are easy to prepare, incredibly tender, and full of flavor. They are perfect for make-ahead meals, feeding a crowd, or stress-free entertaining. The slow cooker ensures even cooking and rich sauce absorption every time.

Ingredients

(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)

Ground beef forms the base of the meatballs. It provides richness and hearty flavor that holds up well during slow cooking.

Breadcrumbs help bind the meatballs and keep them tender rather than dense.

Eggs act as a binder, ensuring the meatballs hold their shape as they cook.

Onion adds moisture and subtle sweetness, enhancing the overall flavor.

Garlic provides savory depth and warmth that complements the meat.

Parmesan cheese adds saltiness and richness, boosting flavor without overpowering the dish.

Milk keeps the meatballs soft and moist during the long cooking process.

Salt enhances the natural flavors of the ingredients.

Black pepper adds mild heat and balance.

Italian seasoning brings herbal notes that pair well with meatballs and sauce.

Marinara sauce forms the cooking base, infusing the meatballs with rich, tomato flavor as they simmer.

Directions

Begin by combining the ground beef, breadcrumbs, eggs, onion, garlic, Parmesan cheese, milk, salt, black pepper, and Italian seasoning in a large bowl. Mix gently until just combined, taking care not to overwork the mixture.

Shape the mixture into evenly sized meatballs. Place them in a single layer in the slow cooker, stacking gently if necessary.

Pour the marinara sauce evenly over the meatballs, ensuring they are mostly covered. Do not stir aggressively, as this can break them apart before they set.

Cover and cook on low until the meatballs are fully cooked and tender. During cooking, the meatballs will absorb flavor from the sauce and release juices that enhance the overall texture.

Once cooked, gently stir to coat the meatballs evenly in sauce. Serve warm with your preferred sides.

Servings and timing

This recipe makes approximately twenty-four meatballs, serving four to six people. Preparation takes about twenty minutes, and cooking time is four hours on low or two hours on high. Total time depends on the selected setting.

Storage/reheating

Store leftover meatballs in an airtight container in the refrigerator for up to four days. Reheat gently on the stovetop or in the microwave. These meatballs also freeze well and can be reheated directly from frozen in sauce.

Variations and Customizations

Slow cooker meatballs are highly adaptable. You can substitute ground turkey or chicken for a lighter version while keeping the same method. I tested this with ground turkey and found the meatballs remained tender when extra milk was added.

For a sweet-and-savory variation, replace part of the marinara sauce with barbecue sauce or grape jelly. This creates a popular party-style meatball with a glossy finish.

If you enjoy spice, add red pepper flakes or a dash of hot sauce to the sauce. This adds warmth without overpowering the meatballs.

Vegetables such as finely chopped bell peppers or grated zucchini can be added to the mixture for extra moisture and nutrition.

Nutrition and Dietary Info

These meatballs provide protein from beef and eggs, carbohydrates from breadcrumbs, and fats that contribute to satiety. Portion size can be adjusted easily, and substitutions allow flexibility for lighter dietary preferences.
