Ingredients

• 1 lb Ground beef
• 0.5 lb Italian sausage
• 0.5 cup Breadcrumbs
• 0.25 cup Milk
• 0.25 cup Parmesan cheese, grated
• 1 large Egg
• 2 cloves Garlic, minced
• 1 tsp Italian seasoning
• 1 tsp Salt
• 0.5 tsp Black pepper, ground
• 1 tbsp Olive oil
• 24 oz Marinara sauce
• 1 lb Spaghetti, uncooked
• 4 cups Water
• 2 tbsp Fresh basil, chopped (optional garnish)
• 0.25 cup Parmesan cheese, grated (for serving)

Directions

Step 1

In a large mixing bowl, combine the ground beef, Italian sausage, breadcrumbs, milk, Parmesan cheese, egg, minced garlic, Italian seasoning, salt, and black pepper. Mix gently with your hands until well combined.

Step 2

Form the meat mixture into golf-ball-sized meatballs (approximately 1.5 inches in diameter). You should end up with around 20 meatballs.

Step 3

Heat the olive oil in a large skillet over medium heat. Sear the meatballs in batches for 1-2 minutes on each side, just until browned. This step locks in flavor and helps the meatballs hold their shape.

Step 4

Transfer the seared meatballs to the slow cooker. Pour the marinara sauce over the meatballs, ensuring they are fully submerged.

Step 5

Cover the slow cooker with the lid and cook on LOW for 4-5 hours (or HIGH for 2-3 hours) until the meatballs are fully cooked and tender.

Step 6

About 30 minutes before serving, break the spaghetti noodles in half and add them to the slow cooker, along with the 4 cups of water. Stir gently to combine and ensure the pasta is submerged in the liquid.

Step 7

Re-cover the slow cooker and cook on HIGH for 25-30 minutes, stirring halfway through to prevent the pasta from sticking together. Check the spaghetti for doneness before serving.

Step 8

Once ready, serve the spaghetti and meatballs topped with fresh basil and additional grated Parmesan cheese, if desired.
