Ingredients

Scale
  • 1 1/2 pounds ground beef (85% lean preferred)
  • 3/4 cup breadcrumbs (plain or Italian)
  • 1 large egg
  • 1/4 cup milk
  • 2 tablespoons Worcestershire sauce
  • 1/2 small yellow onion, finely diced
  • 1 teaspoon garlic powder
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1 tablespoon dried parsley
  • 1 teaspoon Dijon mustard
  • 2 cups beef broth (low-sodium preferred)
  • 1 can (10.5 oz) cream of mushroom soup
  • 1 medium yellow onion, sliced
  • 8 oz button mushrooms, sliced (optional)
  • 1 tablespoon Worcestershire sauce
  • 1/2 teaspoon garlic powder
  • 1/4 teaspoon black pepper
  • 2 tablespoons cornstarch (mixed with 2 tablespoons water, if needed for thickening)

Instructions

  1. In a large mixing bowl, combine ground beef, breadcrumbs, egg, milk, Worcestershire sauce, finely diced onion, garlic powder, salt, black pepper, dried parsley, and Dijon mustard. Mix gently until just combined.
  2. Use a cookie scoop or tablespoon to form 1 1/2-inch meatballs (about 24-28 meatballs). Optionally, brown meatballs in a non-stick skillet over medium heat for 1-2 minutes per side.
  3. Add sliced onion and mushrooms to the bottom of the slow cooker. Arrange meatballs on top in a single layer.
  4. In a bowl, whisk together beef broth, cream of mushroom soup, Worcestershire sauce, garlic powder, and black pepper. Pour evenly over the meatballs.
  5. Cover and cook on LOW for 4-5 hours or on HIGH for 2-2 1/2 hours, until meatballs are cooked through (internal temp should reach 160°F).
  6. If the gravy is thin, mix cornstarch with water and stir into the slow cooker. Cover and cook on HIGH for an additional 15-20 minutes until thickened.
  7. Gently stir, taste, and adjust seasoning if needed. Serve hot over mashed potatoes, egg noodles, or rice.

Notes

For gluten-free, use gluten-free breadcrumbs and arrowroot powder instead of cornstarch. For dairy-free, use non-dairy milk and a dairy-free cream of mushroom soup. Browning the meatballs is optional but adds flavor. If using a hot slow cooker, check for doneness early. Store leftovers in the fridge for up to 4 days or freeze for up to 2 months.
