Step‑by‑Step Instructions for French Onion Meatloaf with Gruyère and Caramelized Onions
Step 1: Prep & Cook Onions
In a skillet, heat 2 tablespoons of olive oil over medium heat. Add 2 finely sliced onions and sauté for 15-20 minutes, stirring occasionally, until they are caramelized and golden brown. Incorporate 2 minced garlic cloves in the last minute of cooking for added flavor. Remove from heat and let the mixture cool slightly.
Step 2: Mix Meatloaf Ingredients
In a large mixing bowl, combine 1 pound of ground beef, 1 pound of ground pork, and 1 cup of breadcrumbs. Pour in 2 eggs, ½ cup of beef broth, 2 tablespoons of Worcestershire sauce, and 1 tablespoon of Dijon mustard. Sprinkle in salt, pepper, and 1 teaspoon of thyme. Gently fold in the cooled caramelized onion and garlic mixture until everything is well combined, taking care not to overmix.
Step 3: Shape & Bake
Preheat your oven to 350°F (175°C). Shape the meat mixture into a loaf and place it in a lightly greased baking dish. Smooth the top for even cooking, making sure it’s compact. Bake for 60-70 minutes or until the internal temperature reaches 160°F (71°C) on a meat thermometer, and the top is nicely browned.
Step 4: Add Gruyère and Rest
During the last 10 minutes of baking, sprinkle 1 cup of shredded Gruyère cheese evenly over the top of the meatloaf for a rich, cheesy crust. Once done, remove the meatloaf from the oven and let it rest for 10 minutes to firm up, making slicing easier and ensuring juicy slices.
Step 5: Serve & Garnish
Carefully slice the French Onion Meatloaf with Gruyère into thick portions. Garnish with fresh chopped parsley for a pop of color and additional flavor. Serve warm alongside your favorite sides, such as mashed potatoes or a fresh salad, to complete your comforting meal.
