for the meatballs:
2 pounds (900g) ground chicken or lean ground beef
1/3 of the caramelized onions
2 cloves garlic pressed through a garlic press
2 teaspoons thyme
1/4 cup (60ml) milk
2 eggs
1/2 cup (65g) fine breadcrumbs
1 cup (100g) grated Gruyere cheese
1 tablespoon fine sea salt or to your taste
1/2 teaspoon ground black pepper
2 tablespoons frying oil for cooking the meatballs
for the gravy:
1 tablespoon butter
3 cloves garlic finely chopped with a knife
2 tablespoons flour
1/3 cup (80ml) dry white wine
2 cups (480ml) good-quality beef broth or chicken broth
2 teaspoons Worcestershire sauce
salt and pepper to taste
2/3 of the caramelized onions
1 1/2 cups (150g) grated Gruyere cheese
1 tablespoon chopped parsley to garnish
Instructions
Caramelized Onions:
Peel and thinly slice the onions. Heat olive oil in a pan over medium-low heat, add onions and a pinch of salt. Cook, stirring occasionally, until deeply golden and caramelized, about 25-30 minutes.
Meatballs:
In a bowl, combine ground chicken or beef, 1/3 of the caramelized onions, garlic, thyme, milk, eggs, breadcrumbs, grated Gruyere, salt, and pepper. Mix until combined. Form into balls.
Heat frying oil in a pan and brown meatballs in batches on all sides. Remove and set aside.
Gravy:
Melt butter in the same pan, add chopped garlic and cook for 1 minute. Stir in flour and cook another minute. Pour in white wine and reduce slightly. Add broth, Worcestershire sauce, salt, and pepper. Simmer until slightly thickened.
Return 2/3 of the caramelized onions to the pan, stir. Add back the browned meatballs and simmer in the sauce to finish cooking through.
Topping:
Sprinkle Gruyere cheese over the meatballs and sauce, cover, and cook until melted, or place under a broiler until cheese is bubbly. Garnish with chopped parsley.
