Slow-Cooker Meatball Sandwiches

These huge sandwiches and their kicky sauce will satisfy the hungriest of your crew. To trim preparation time, substitute an 18-ounce package of frozen cooked meatballs (about 32 meatballs) for the homemade ones. Stir the frozen meatballs into the sauce to coat, then cook as directed.


  • 1 egg, lightly beaten
  • 1/3 cup fine dry bread crumbs
  • 2/3 cup finely chopped onion (2 small)
  • 1/2 teaspoon salt
  • 1/2 teaspoon dried oregano, crushed
  • 1/4 teaspoon ground black pepper
  • 1 1/2 pounds lean ground beef
  • 1 15 – ounce can tomato sauce
  • 1/2 cup chopped green sweet pepper (1 small)
  • 2 tablespoons packed brown sugar
  • 1 tablespoon yellow mustard
  • 1 teaspoon chili powder
  • 1/4 teaspoon garlic salt
  • 1/4 teaspoon ground black pepper
  • 1/8 teaspoon bottled hot pepper sauce
  • 8 hoagie buns, split and toasted
  • 2 cups shredded mozzarela cheese (8 ounces)


  1. In a large bowl, stir together egg, bread crumbs, 1/3 cup onion, the salt, oregano, and 1/4 teaspoon black pepper. Add ground beef; mix well. Shape meat mixture into 32 balls. 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.
  2. For the sauce, 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 teaspoon black pepper, and the hot pepper sauce. Add cooked meatballs, stirring gently to coat with sauce.
  3. Cover and cook on low-heat setting for 3 to 4 hours or on high-heat setting for 1-1/2 to 2 hours.
  4. Place four meatballs on the bottom of each bun. Top with some of the sauce and some of the cheese. Add bun tops. Makes 8 servings.
