Prep: 20 min · Cook: 45 min · Yield: 4 · Method: Stovetop

Ingredients

• 1 lb ground beef
• 1 large egg
• 0.5 cup plain breadcrumbs
• 2 cloves garlic
• 1 teaspoon kosher salt
• 0.5 teaspoon black pepper
• 2 large yellow onions
• 2 tablespoons olive oil
• 2 cups beef broth
• 1 tablespoon worcestershire sauce
• 4 sprigs fresh thyme
• 1 cup gruyère cheese

Cooking instructions

1. In a large bowl, combine the ground beef, egg, breadcrumbs, garlic, salt, and pepper. Mix gently just until combined, then form 16 meatballs. (about 10 min)
2. Heat a large deep skillet over medium heat. Add the meatballs and cook, turning occasionally, until browned and the centers reach 160°F (71°C), about 10 to 12 minutes. Transfer them to a plate. (about 12 min) — 160°F (71°C)
3. Add the olive oil to the skillet, then add the onions. Cook over medium-low heat, stirring occasionally, until deeply golden and softened, 18 to 22 minutes. (about 22 min) — Medium-low
4. Pour in the beef broth and Worcestershire sauce, add the thyme, and scrape up any browned bits. Bring to a simmer and cook for 5 minutes. (about 5 min) — Simmer
5. Return the meatballs to the skillet and simmer until heated through, about 3 minutes. Sprinkle the Gruyère evenly over the meatballs, cover, and cook until the cheese melts, 2 to 3 minutes. Remove the thyme sprigs and serve hot. (about 3 min) — Simmer
