How To Serve
Serve with Pepperoncini Garlic Bread and a green salad with Creamy Italian Dressing to round out the meal. These meatballs also make a great meatball sub.
Shape and Brown The Meatballs
Combine all the meatball ingredients and shape into 14 to 18 meatballs. Broil them for 8 to 10 minutes to get them browned on the outside. This extra step gives the meatballs so much more flavor.
How Long In The Slow Cooker
The meatballs take 5 to 6 hours on LOW or 3 to 4 hours on HIGH. Because the meatballs slow cook in the sauce, the sauce is extra flavorful and the meatballs stay wonderfully moist.

Use Meatloaf Mix
Meatloaf mix is a combination of ground beef, pork, and veal and it makes super tasty and tender meatballs. If you can’t find meatloaf mix at the store, you can use equal parts of ground beef and ground pork or you can use all ground beef. Use a ground beef that is 85 to 90% lean. You want some fat in the meat so that the meatballs are tender and moist.
Slow Cooker Spicy Meatballs and Marinara Recipe Tips
Reduce the amount of crushed red pepper flakes if you want meatballs that are just slightly spicy.
For extra flavor, sprinkle some chopped fresh basil on top of the sauce just before serving.
