Step‑by‑Step Instructions for French Onions Meatloaf
Step 1: Preheat and Prepare the Pan
Begin by preheating your oven to 350°F (175°C). While the oven heats, line a 9×5-inch loaf pan with aluminum foil, allowing some overhang for easy removal later. This will ensure your French Onion Meatloaf cooks evenly and retains its delicious flavors without sticking.
Step 2: Caramelize the Onions
In a large pot over medium-high heat, pour in a few tablespoons of olive oil. Add the thinly sliced yellow onions and a pinch of baking soda to help with caramelization. Sauté the onions for about 25-30 minutes, stirring occasionally, until they are a rich golden brown and beautifully softened, creating an aromatic base for your meatloaf.
Step 3: Mix the Base Ingredients
In a mixing bowl, combine ½ cup of plain dried breadcrumbs with ½ cup of whole milk, allowing the breadcrumbs to absorb the liquid. Once the onions have finished caramelizing, stir in the onions (reserving some for topping), minced garlic, Worcestershire sauce, kosher salt, and ground black pepper. Mix until well combined to form a flavorful base for your French Onion Meatloaf.
Step 4: Incorporate the Meat and Eggs
Now, add 2 pounds of your choice of ground meat (beef, veal, or a mix) into the bowl with the onion mixture. Gently fold in 2 beaten large eggs, being careful not to overmix, as this can lead to a dense texture in your meatloaf. Aim for a well-integrated blend that maintains a light and fluffy consistency.
Step 5: Shape and Bake the Meatloaf
Transfer the meat mixture into the prepared loaf pan, shaping it evenly without packing too tightly. Place the loaf pan in the preheated oven and bake for about 55-60 minutes. When ready, the internal temperature should reach 165°F (74°C), indicating that your French Onion Meatloaf is thoroughly cooked.
Step 6: Broil for a Cheesy Topping
After baking, remove the meatloaf from the oven. Sprinkle the reserved caramelized onions on top, followed by 1 cup of shredded Gruyère cheese for that melty finish. Set the oven to broil and return the meatloaf for an additional 2 minutes or until the cheese is bubbly and slightly golden, adding a delightful crust to this comforting dish.
Step 7: Rest and Slice
Once broiling is complete, take the meatloaf out and allow it to rest for 15 minutes. This resting time will help the juices settle, making it easier to slice. When ready, carefully lift the meatloaf from the pan using the foil edges, slice generously, and prepare to enjoy the delightful flavors of your homemade French Onion Meatloaf.

Storage Tips for French Onion Meatloaf
Fridge: Store leftovers in an airtight container for up to 3 days to maintain freshness and flavor.
Freezer: For longer storage, freeze the meatloaf wrapped tightly in plastic wrap and then in aluminum foil for up to 3 months.
Reheating: Thaw overnight in the fridge before reheating. Warm slices in the oven at 350°F for about 15-20 minutes until heated through for the best texture.
Make-Ahead: Prepare the meatloaf mixture a day in advance and refrigerate it. Allow it to come to room temperature before baking for optimal results.
Expert Tips for French Onion Meatloaf
