Step‑by‑Step Instructions for French Onion Meatloaf Recipe
Step 1: Caramelize the Onions
In a large skillet, melt 1 tablespoon of olive oil and 2 tablespoons of butter over medium heat. Add thinly sliced onions and sauté them for about 20–25 minutes, stirring occasionally until they are golden brown and caramelized. This process develops their natural sweetness. In the last minute of cooking, add minced garlic and let it cook for an additional 1–2 minutes until fragrant.
Step 2: Prepare the Meatloaf Mixture
In a spacious mixing bowl, combine ground beef, eggs, breadcrumbs, Worcestershire sauce, dried thyme, and a generous pinch of salt and pepper. Mix thoroughly using your hands or a fork until everything is well incorporated. Fold in half of the caramelized onions, ensuring that each bite of your French Onion Meatloaf bursts with flavor.
Step 3: Shape the Meatloaf
Preheat your oven to 350°F (175°C). Once the meat mixture is ready, transfer it onto a parchment-lined baking dish or into a loaf pan. Using your hands, shape the mixture into a neat loaf, making sure to create an even surface for consistent cooking. Place it in the preheated oven to bake, filling your kitchen with mouthwatering aromas.
Step 4: Bake the Meatloaf
Bake the shaped meatloaf in the oven for 45–50 minutes, or until the internal temperature reaches 160°F (71°C). You’ll know it’s done when the top is nicely browned and the juices run clear. It’s essential that the meatloaf stays moist, so keep an eye on it while it bakes.
Step 5: Make the Onion Sauce
While the meatloaf is baking, take the remaining caramelized onions and combine them with some beef broth in the same skillet. Simmer the mixture over medium heat for 5–7 minutes until it slightly thickens, allowing the flavors to meld together beautifully. This sauce will add a gourmet touch to your meatloaf.
Step 6: Add the Gruyère Cheese
Once the meatloaf is baked to perfection, remove it from the oven and sprinkle grated Gruyère cheese evenly over the top. Place the meatloaf back in the oven and broil for 3–5 minutes, or until the cheese is melty and bubbly. Watch closely to ensure it doesn’t burn, as this adds a delightful creamy texture to your French Onion Meatloaf.
Step 7: Rest and Serve
After broiling, let the meatloaf rest for 5–10 minutes before slicing. This resting period allows the juices to redistribute, making each slice succulent and flavorful. Serve it warm, drizzled with the onion sauce, for a comforting and delicious meal the whole family will love.
