Ingredients for Slow Cooker Mozzarella Stuffed Meatballs

- 1 lb ground beef – Juicy and tender, this is the star ingredient that forms the base of your meatballs.
- 1/2 cup breadcrumbs – These breadcrumbs add a lovely texture that helps bind the meat mixture together.
- 1/4 cup grated Parmesan cheese – Cheesy goodness brings saltiness and enhances flavor with a savory twist.
- 1 large egg – Acts as a binder, marrying all the ingredients for a consistent texture.
- 2 cloves garlic, minced – Fresh garlic elevates the taste with aromatic and rich notes.
- 1 tsp Italian seasoning – A mix of herbs like basil, oregano, and thyme adds depth to your meatballs.
- 1/2 tsp salt & 1/4 tsp black pepper – Simple yet essential for enhancing the flavors.
- 4 oz mozzarella cheese, cut into small cubes – The secret heart of the meatballs, offering gooey, melty cheese.
- 3 cups marinara sauce – Provides a juicy base for the meatballs, perfect for soaking up flavors.
- Fresh parsley, chopped (optional, for garnish) – A pop of color and a fresh finish.
Step-by-Step Directions
- In a large bowl, combine the ground beef, breadcrumbs, Parmesan cheese, egg, minced garlic, Italian seasoning, salt, and black pepper. Mix until just combined—avoid overmixing to keep the meatballs tender.
- Take a scoop of the meat mixture and flatten it slightly in your hand. Place a cube of mozzarella cheese in the center and carefully form the meat around it, sealing the cheese completely inside. This step ensures that the cheesy filling remains hidden until the first bite.
- Place the stuffed meatballs in the bottom of the slow cooker, making sure they are arranged in a single layer for even cooking.
- Pour the marinara sauce evenly over the meatballs, ensuring they are fully covered with sauce. This allows them to soak up all that rich flavor while cooking.
- Cover and cook on low for 4–6 hours or on high for 2–3 hours, until the meatballs are cooked through and the cheese is beautifully melted inside.
- Once done, serve warm, optionally garnished with chopped fresh parsley for an extra touch of color and flavor.
