Slow Cooker Meatballs are a comforting, fuss-free way to create a hearty meal any night of the week. These juicy bites of seasoned meat simmer in a fragrant basil marinara that tastes like it’s been bubbling on the stovetop all day—without the need to watch a pot. Get ready to fill your kitchen with the aromas of garlic, tomatoes, and fresh herbs!

Ingredients

- 1 pound ground beef (or turkey)
- 1/2 cup breadcrumbs (use panko or Italian-style for extra flavor)
- 1 large egg, lightly beaten
- 2 cloves garlic, minced
- 1 teaspoon dried Italian seasoning
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 2 cups tomato sauce (marinara preferred)
- 1/4 cup fresh basil leaves, roughly chopped
- Olive oil for browning (optional)
Instructions
1. In a large mixing bowl, combine the ground meat, breadcrumbs, beaten egg, minced garlic, Italian seasoning, salt, and black pepper. Mix gently until the ingredients are well incorporated, being careful not to overwork the mixture.
2. Shape the mixture into small meatballs, about the size of a golf ball. For extra flavor and a bit of color, brown the meatballs in a drizzle of olive oil in a skillet over medium-high heat. This step is optional, but it helps lock in juices and lends a richer taste to the sauce.

3. Transfer the meatballs to your slow cooker and pour in the marinara sauce, along with half of the fresh basil. Gently stir to coat the meatballs, then cover and cook on low for 6 hours or on high for 3 hours. The meatballs should be fully cooked and incredibly tender by the end of the cooking time.
4. Once done, garnish with the remaining fresh basil for a burst of herbal sweetness. Serve the meatballs atop a bed of spaghetti, tuck them into warm hoagie rolls with melted cheese, or enjoy them just as they are.
These Hearty Basil Marinara Slow Cooker Meatballs are a perfect solution for busy families, meal preppers, or anyone craving traditional Italian flavors without babysitting a stove. Health-wise, swap ground beef for turkey or chicken, or use gluten-free breadcrumbs if needed.
Other variations include adding chili flakes for a spicy kick or substituting spinach for basil to switch it up. However you enjoy them, these tender, flavorful meatballs will bring a cozy, home-cooked vibe to any meal.
