Step‑by‑Step Instructions for French Onion Meatloaf
Step 1: Preheat and Prepare
Start by preheating your oven to 350°F (175°C). While it heats, line a 9×5-inch loaf pan with aluminum foil, leaving overhang on the edges for easy removal later. This simple step ensures your French Onion Meatloaf cooks evenly and makes cleanup a breeze.
Step 2: Caramelize the Onions
In a heavy-bottomed pot, heat 2 tablespoons of olive oil over medium-high heat. Add 2 pounds of thinly sliced yellow onions along with 1/8 teaspoon of baking soda. Cook for 15 minutes, stirring lightly, then reduce heat and stir often for another 10-15 minutes until the onions turn a deep golden brown. This caramelization process is key to developing the rich flavors in your meatloaf.
Step 3: Combine the Ingredients
In a large bowl, mix 1/2 cup of dried breadcrumbs with 1/2 cup of whole milk, allowing them to soak for a few minutes. Next, stir in most of the caramelized onions—saving some for the topping—along with 2 minced garlic cloves, 2 teaspoons of Worcestershire sauce, 1.5 teaspoons of kosher salt, and 1/4 teaspoon of ground black pepper. This blend infuses the meatloaf with a depth of flavor that is truly irresistible.
Step 4: Mix in the Meat
Add 2 pounds of ground beef and 2 beaten eggs to the mixture. Gently combine the ingredients using your hands or a spatula, being careful not to overmix. Transfer this mixture into your prepared loaf pan, pressing it down evenly to ensure it holds its shape during baking.
Step 5: Bake the Meatloaf
Place the loaf pan in the preheated oven and bake for 55-60 minutes, or until the internal temperature reaches 165°F (74°C). The edges should be golden and the meatloaf firm to the touch, creating that perfect comforting exterior while remaining juicy inside.
Step 6: Broil for the Perfect Finish
After baking, switch your oven to broil. Top your meatloaf with the reserved caramelized onions and sprinkle 1 cup of shredded Gruyère cheese over the top. Broil for about 2 minutes, or until the cheese is melted, bubbly, and golden. This step adds a delightful, gooey finish that complements the savory meatloaf beautifully.
Step 7: Cool and Serve
Let the French Onion Meatloaf cool in the pan for 15 minutes. This cooling time allows it to set, making slicing easier. Carefully lift it from the pan using the foil overhang and transfer it to a cutting board. Slice and serve warm, enjoying the comforting blend of flavors and textures you’ve created!
