  • Servings:



1 egg, lightly beaten
1/3 c bread crumbs, fine dry
2/3 c. onion, finely chopped (2 small)
1/2 tsp. salt
1/2 tsp. dried oregano, crushed
1/4 tsp. pepper, black, ground
1 1/2 lb. lean ground beef

1/8 tsp. pepper sauce, hot, bottled
8 buns, hoagie, split and toasted
2 c. cheese, mozzarella, shredded (8 oz.)

I’m a little partial with this recipe, as I love meatball sandwiches, so Slow Cooker Meatball Sandwiches is at the top of my list!


  1. Stir together egg, bread crumbs, 1/3 cup onion, the salt, oregano, and 1/4 tsp. black pepper in a large bowl. Add ground beef; mix well.
  2. Shape meat mixture into 32 balls.
  3. Arrange meatballs in a single layer in an ungreased 15x10x1-inch baking pan. Bake, uncovered, in a 350 degree F oven for 25 minutes. Drain off fat.
  4. In a 3-1/2 or 4-quart slow cooker, stir together tomato sauce, the remaining 1/3 cup onion, the sweet pepper, brown sugar, mustard, chili powder, garlic salt, 1/4 tsp. black pepper, and the hot pepper sauce.
  5. Add cooked meatballs, stirring gently to coat with sauce.
  6. Cover. Cook on Low for 3 to 4 hours or on High for 1-1/2 to 2 hours.
  7. Place four meatballs on the bottom of each bun. Top with some of the sauce and a slice of cheese.
  8. Place under broiler for a minute of so to melt cheese and brown.

Why don’t you just cook the meatballs in the crockpot? Will the juices make the sauce to runny?Couldn’t you compensate for that my adding some tomato paste?

The sauce isn’t really what I was looking for in. Meatball hoagie bit would make a killer sloppy Joe sauce.
