Step‑by‑Step Instructions for French Onions Meatloaf
Step 1: Preheat Your Oven
Begin by preheating your oven to 350°F (175°C). While the oven heats up, prepare your 9×5-inch loaf pan by lining it with aluminum foil, allowing for easy removal later. This French Onions Meatloaf will need a warm environment to cook evenly, so this step sets the stage for a perfectly baked dish.
Step 2: Caramelize the Onions
In a heavy-bottomed pot, heat 2 tablespoons of olive oil over medium heat. Add 2 sliced yellow onions along with 1/2 teaspoon of baking soda, stirring occasionally for about 25-30 minutes. Look for a deep golden brown color to develop on the onions, which signals they are caramelized and ready to bring their sweetness into your meatloaf.
Step 3: Prepare the Meatloaf Mixture
In a large mixing bowl, combine 1 cup of plain dried breadcrumbs with 1/2 cup of whole milk. Allow the breadcrumbs to soak for a few minutes before adding in the caramelized onions, 2 minced garlic cloves, 2 tablespoons of Worcestershire sauce, and a generous pinch of kosher salt and ground black pepper. Mix these ingredients together until well combined, ensuring the flavors meld beautifully.
Step 4: Combine Meat and Bind
Next, incorporate 1 pound of ground beef and/or veal along with 2 large eggs into the onion and breadcrumb mixture. Using your hands or a spatula, gently combine the ingredients, being careful not to overmix, as this will help maintain a tender texture in your French Onions Meatloaf.
Step 5: Transfer to the Loaf Pan
Once your mixture is well combined, transfer it to the prepared loaf pan. Smooth the top with a spatula to create an even layer, ensuring it fits snugly in the pan. This will help the meatloaf hold its shape while baking and achieve a nice rise.
Step 6: Bake the Meatloaf
Place the loaf pan in the preheated oven and bake for 55-60 minutes. Use an instant-read thermometer to check the internal temperature, which should reach 165°F (74°C) for safe consumption. The edges should appear crispy, while the center remains juicy and flavorful.
Step 7: Broil for a Golden Topping
During the last 2 minutes of baking, remove the meatloaf from the oven and sprinkle a generous layer of 1 cup of shredded Gruyère cheese and any reserved caramelized onions on top. Return the pan to the oven, turning on the broiler to achieve a bubbly, golden crust. Watch closely to avoid burning!
Step 8: Cool and Serve
After broiling, remove the meatloaf from the oven and let it cool for about 15 minutes. Carefully lift the meatloaf out of the pan using the aluminum foil, slice it into thick pieces, and serve warm. The savory flavors of your French Onions Meatloaf will surely impress your family and friends!

Make Ahead Options
These French Onion Meatloaf preparations are a lifesaver for busy weeknights! You can prepare the entire meatloaf mixture, including the caramelized onions, and refrigerate it for up to 24 hours before baking. To do this, simply follow steps 1 to 4, then cover the mixture tightly with plastic wrap or store it in an airtight container to maintain its moisture and prevent browning. When you’re ready to cook, just transfer the mixture to the loaf pan and bake as directed. This method not only saves you time but ensures that the meatloaf remains just as delicious and flavorful as when freshly made, giving you a comforting meal with minimal effort.
