For the Meatballs:

  • 1 pound ground beef
  • ½ cup breadcrumbs
  • 1 egg
  • 2 cloves garlic minced
  • 1 teaspoon Worcestershire sauce
  • 1 teaspoon salt
  • ½ teaspoon black pepper
  • ½ teaspoon onion powder

For the Sauce:

  • 2 tablespoons butter
  • 2 large onions thinly sliced
  • 1 teaspoon sugar
  • 1 teaspoon thyme fresh or dried
  • 1 tablespoon flour
  • 1 cup beef broth
  • ½ cup shredded Gruyère or mozzarella cheese

Instructions
 

Make the Meatballs:

  • In a bowl, combine ground beef, breadcrumbs, egg, garlic, Worcestershire sauce, salt, pepper, and onion powder. Mix and shape into 1-inch balls.

Brown the Meatballs:

  • Heat oil in a skillet over medium heat. Brown meatballs on all sides until golden. Remove and set aside.

Caramelize the Onions:

  • In the same pan, melt butter. Add onions and sugar, cooking slowly for 15–20 minutes until golden and caramelized.

Make the Sauce:

  • Sprinkle flour over onions, stir, then add beef broth and thyme. Simmer until slightly thickened.

Combine and Serve:

  • Return meatballs to the skillet, cover with sauce, and sprinkle cheese on top. Broil or cover until melted and bubbly. Serve hot.

Notes

  • Make Ahead: Cook and store meatballs and sauce separately. Reheat together before serving.
  • Customizing the Flavor: Add mushrooms or a splash of sherry for an extra-rich sauce.
  • Serving Suggestions: Pair with mashed potatoes, egg noodles, or crusty bread.
  • Allergy-Friendly Options: Substitute breadcrumbs with almond flour for a gluten-free version.
  • Storage Tips: Store leftovers in an airtight container for up to 3 days. Reheat gently in a skillet or oven.
