Ingredients

Scale

Meat and Protein:

  • 1.5 pounds ground beef (85/15 ratio)
  • 1 egg (whisked)
  • 1 cup shredded mozzarella cheese
  • 0.75 cup grated Gruyere cheese

Herbs, Breadcrumbs, and Seasonings:

  • 1.5 cups fresh breadcrumbs (or panko breadcrumbs)
  • 0.25 cup plus 2 tablespoons whole milk
  • 1 tablespoon chopped fresh parsley
  • 1 teaspoon fresh thyme leaves
  • 1 teaspoon herbes de Provence
  • 1 teaspoon dried thyme
  • 1 teaspoon salt
  • 0.25 teaspoon black pepper

Aromatics and Cooking Ingredients:

  • 2.5 large white onions (halved and thinly sliced)
  • 0.5 large white onion (finely minced)
  • 8 cloves garlic (minced)
  • 4 tablespoons olive oil
  • 2 tablespoons butter
  • 0.25 cup sherry or white wine
  • 1.5 tablespoons flour
  • 2.25 cups beef stock
  • 2 teaspoons fresh thyme leaves

Instructions

  1. Hydrate breadcrumbs by immersing them in milk for a quick 5-minute softening process.
  2. Create meatball mixture by gently folding ground beef with softened breadcrumbs, incorporating herbs, seasonings, minced aromatics, cheese, and whisked egg. Blend carefully to maintain meat’s tender texture.
  3. Shape uniform meatballs using two-tablespoon portions. Chill the formed meatballs for 15 minutes to help maintain structural integrity during cooking.
  4. Sear meatballs in a large oven-safe skillet with olive oil over medium-high heat. Brown thoroughly on all surfaces for 8-10 minutes, ensuring rich caramelized exterior. Transfer seared meatballs to a separate plate.
  5. Using the same skillet, add additional olive oil and butter. Introduce sliced onions with a seasoning of salt and pepper. Slowly transform onions through continuous stirring for 20-25 minutes until deeply golden and luxuriously soft.
  6. Enhance caramelized onions by introducing minced garlic and aromatic herbs. Toast briefly for 30 seconds to release intense fragrance.
  7. Deglaze the skillet with sherry, allowing quick reduction. Dust with flour and cook momentarily to create sauce foundation.
  8. Stream beef stock gradually, whisking continuously to develop smooth, velvety sauce. Simmer for 5 minutes until sauce reaches desired consistency. Finish with fresh thyme leaves.
  9. Activate broiler at high temperature. Nestle seared meatballs into the onion sauce, creating a cohesive ensemble.
  10. Lavishly sprinkle remaining Gruyere and mozzarella cheeses over meatballs. Position skillet under broiler for 5-7 minutes until cheese melts into bubbling, golden perfection.
  11. Garnish with additional thyme leaves. Serve immediately alongside crusty bread or creamy mashed potatoes for a comforting, restaurant-quality dining experience.

Notes

  • Breadcrumb Soaking Helps create a tender, moist texture by preventing the meat from becoming dense and tough.
  • Gentle Mixing Prevents overworking the meat, which can make meatballs rubbery and compact, ensuring a light and delicate final result.
  • Chilling Meatballs Allows them to firm up, helping them hold their shape during cooking and preventing them from falling apart in the pan.
  • Cheese Selection Use a combination of Gruyere and mozzarella for a rich, complex flavor profile that melts beautifully and adds creamy texture.
  • Caramelization Technique Low and slow cooking of onions develops deep, sweet flavor and ensures they become soft and golden without burning.
