Step-by-Step Instructions

Step 1: Prepare the Meatballs

1. In a large mixing bowl, combine ground beef, breadcrumbs, Parmesan cheese, egg, minced garlic, onion powder, Italian seasoning, salt, and pepper.
2. Mix gently until just combined—overmixing can make meatballs tough.
3. Shape the mixture into 1 1/2-inch meatballs and place them on a plate or baking sheet.

Step 2: Brown the Meatballs

1. Heat a large skillet over medium heat and add 1–2 tablespoons of olive oil.
2. Sear the meatballs in batches, turning occasionally, until browned on all sides (they don’t need to be fully cooked through at this stage).
3. Remove the meatballs from the skillet and set aside.

Step 3: Caramelize the Onions

1. In the same skillet, add butter and sliced onions.
2. Cook over medium-low heat, stirring occasionally, until the onions are soft and golden brown (about 15–20 minutes).
3. Sprinkle with sugar to enhance caramelization.

Step 4: Make the Sauce

1. Stir in the flour and cook for 1 minute to eliminate raw flour taste.
2. Gradually add beef broth, Worcestershire sauce, and wine (if using), whisking constantly.
3. Bring the mixture to a simmer and let it thicken slightly (about 3–5 minutes).

Step 5: Combine Meatballs and Sauce

1. Gently return the meatballs to the skillet, nestling them in the onion sauce.
2. Reduce heat to low, cover, and simmer for 10–15 minutes until meatballs are cooked through (internal temperature 160°F / 71°C).

Step 6: Add Cheese and Finish

1. Sprinkle shredded Gruyère over the meatballs.
2. Cover the skillet with a lid for 2–3 minutes, or transfer to a preheated broiler to melt the cheese until bubbly and slightly golden.
3. Garnish with fresh parsley and serve immediately.

Tips & Variations

• Cheese swaps: Swiss or fontina are great alternatives if you prefer a milder or creamier melt.
• Meat alternatives: Ground turkey, chicken, or pork can be used for a lighter version.
• Make it spicier: Add crushed red pepper flakes to the meatball mixture or sauce.
• Vegetarian option: Use lentils or plant-based meat crumbles and vegetable broth in place of beef.
• Onion variations: Red onions add a slightly sweeter flavor; shallots create a more delicate profile.

Pro Cooking Tips

• Use a meat thermometer to ensure perfectly cooked meatballs—avoid drying them out.
• Pat onions dry with a paper towel if they release too much liquid while caramelizing to speed browning.
• Let meatballs rest a few minutes after cooking for maximum juiciness.
