Step-by-Step Instructions

Step 1: Make the Meatballs

1. Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper or lightly grease it.
2. In a large mixing bowl, combine ground beef, breadcrumbs, egg, garlic powder, dried thyme, salt, and pepper. Mix until just combined—avoid overmixing to keep the meatballs tender.
3. Shape the mixture into golf ball-sized meatballs and arrange them on the prepared baking sheet.
4. Bake for 20 minutes or until cooked through. Set aside while you prepare the onion gravy.

Step 2: Caramelize the Onions

1. In a large skillet, melt butter over medium heat. Add the thinly sliced onions and reduce the heat to low.
2. Cook the onions for 20–25 minutes, stirring occasionally, until they’re golden brown and caramelized. Patience is key to developing their rich, sweet flavor.
3. Sprinkle the flour over the onions and stir for 1–2 minutes to eliminate the raw flour taste.

Step 3: Prepare the Gravy

1. Gradually pour in the beef broth, stirring constantly to create a smooth, rich gravy. Bring the mixture to a simmer and cook until it thickens slightly, about 3–5 minutes.
2. Season the gravy with salt and pepper to taste.

Expert Tips for the Best French Onion Meatballs

1. Choose the Right Onions

Yellow onions are the best choice for caramelizing due to their natural sweetness. However, white or red onions can also work if you prefer a slightly different flavor.

2. Don’t Rush the Onions

Caramelizing onions takes time. Keep the heat low and stir occasionally to ensure they cook evenly without burning.

3. Make It Ahead

You can prepare the meatballs and caramelized onions in advance. Store them separately in the fridge and assemble the dish just before serving.

4. Customize the Cheese

Gruyère is the traditional choice for its nutty flavor and excellent melting quality, but Swiss or even mozzarella can be used as substitutes.

5. Add Wine for Depth

If you prefer a richer sauce, deglaze the skillet with a splash of white or red wine before adding the beef broth.
