Ingredients:

1 lb (450g) ground beef

1 egg

½ cup breadcrumbs

¼ cup milk

1 tsp garlic powder

1 tsp onion powder

1 tsp salt

½ tsp black pepper

1 tbsp Worcestershire sauce

1 cup shredded mozzarella (or Gruyère for classic flavor)

For the Onion Gravy:

2 tbsp butter

2 medium onions, thinly sliced

1 tsp sugar

1 tsp fresh thyme (or ½ tsp dried)

 

1 cup beef broth

1 tbsp flour

Salt & pepper to taste

Instructions:

1. Make the Meatballs:

In a bowl, mix beef, egg, breadcrumbs, milk, garlic powder, onion powder, salt, pepper, and Worcestershire.

Form into 12–14 meatballs.

2. Cook the Meatballs:

In a skillet, brown meatballs on all sides until mostly cooked (they will finish in the oven).

3. Caramelize the Onions:

In the same skillet, melt butter and cook onions with sugar until golden (10 minutes).

Stir in flour, thyme, and beef broth. Simmer until slightly thickened.

4. Bake:

Place meatballs in a baking dish, pour onion gravy over, and top with shredded cheese.

Broil or bake at 400°F (200°C) for 10 minutes until cheese is melted and bubbly.

5. Serve Hot:

Garnish with parsley. Perfect with mashed potatoes, rice, or crusty bread
