Ingredients

Scale
  • 1.5 lbs ground beef (85% lean)
  • 1/2 cup bread crumbs (plain or Italian-style, or panko)
  • 1/4 cup milk (dairy or unsweetened non-dairy)
  • 1 large egg
  • 2 tbsp Worcestershire sauce
  • 1 tsp Dijon mustard
  • 1 tsp onion powder
  • 1/2 tsp garlic powder
  • 1/2 tsp salt
  • 1/2 tsp black pepper
  • 2 tbsp fresh parsley, finely chopped (optional)
  • 1 medium yellow onion, thinly sliced
  • 8 oz cremini or white mushrooms, sliced
  • 2 cups beef broth (low sodium preferred)
  • 1 tbsp Worcestershire sauce
  • 2 tbsp ketchup
  • 2 cloves garlic, minced
  • 2 tbsp cornstarch (mixed with 2 tbsp cold water)
  • Salt and pepper, to taste

Instructions

  1. In a large bowl, combine ground beef, bread crumbs, milk, egg, Worcestershire sauce, Dijon mustard, onion powder, garlic powder, salt, pepper, and parsley (if using). Mix gently until just combined.
  2. Shape the mixture into 1.5-inch meatballs (about 18-20 meatballs). If sticky, oil your hands or chill mixture before rolling.
  3. Optional: Brown meatballs in a nonstick skillet over medium heat for 1-2 minutes per side until lightly golden.
  4. Scatter sliced onions and mushrooms in the bottom of a 4-6 quart slow cooker. Place meatballs on top.
  5. In a measuring cup, mix beef broth, Worcestershire sauce, ketchup, and minced garlic. Pour over meatballs and veggies.
  6. Cover and cook on LOW for 5-6 hours or HIGH for 2.5-3 hours, until meatballs are tender and onions are soft.
  7. Whisk together cornstarch and cold water to make a slurry. Stir into the slow cooker. Cover and cook on HIGH for 20-30 minutes, until gravy thickens.
  8. Taste and adjust salt and pepper as needed. Serve hot over mashed potatoes, noodles, or rice with plenty of gravy.

Notes

For gluten-free, use certified GF breadcrumbs and check Worcestershire sauce. Browning meatballs is optional but adds flavor. If gravy is too thin, add more cornstarch slurry. Can substitute ground turkey or chicken. Leftovers keep well and freeze beautifully.
