Slow-Cooker Meatball Subs

The most wonderful meatballs and so easy to do. The idea behind this is just super–I had never thought to put it all together in the crock pot and let the flavors blend.

One of my kids’ favorite meals and meatball subs are now on our monthly rotation..

You can use ground turkey if you like and the meatballs can be prepared ahead of time and frozen.

Slow-Cooker Meatball Subs

Serves 6-8


1 lb lean ground beef
1⁄2 cup dry breadcrumbs
2 tablespoons finely chopped onions or 1⁄4-1⁄2 teaspoon onion powder
1 teaspoon salt
1⁄2 teaspoon Worcestershire sauce
1 egg
1 tablespoon Parmesan cheese, grated
1 (32 ounce) jar spaghetti sauce
6 -8 sub rolls (hoagie rolls) or 6 -8 hot dog buns
mozzarella cheese (sliced or shredded)


Place first seven ingredients in large bowl. Mix thoroughly with your hands just until combined. (I wear food prep gloves.) Shape into approximately 30 1-inch balls.

Bake in an ungreased oblong pan (13x9x2) in a 400°F oven until light brown, 20-25 minutes. OR: microwave meatballs in an ungreased baking dish, 6 minutes on High, turning once. OR: cook over medium heat in frying pan, turning occasionally, until brown, about 20 minutes.

Place cooked meatballs and spaghetti sauce in crock pot. Cook on low for about 2 hours. If you cook longer, stir every hour or so.

Place meatballs and sauce in buns/rolls and top with mozzarella cheese. Bake in the oven for about 6 minutes to get toasty

(A friend places the raw meatballs & sauce in the crock-pot and cooks them for 8+ hours on low, but I have never tried this.).
