How to Make French Onion Meatloaf
Step 1: Prepare the Onion Mixture
Heat the olive oil in a skillet over medium heat. Add the chopped onion and cook, stirring frequently, for about 10β12 minutes until the onion is caramelized and softened. Add the minced garlic in the last minute of cooking and cook until fragrant. Remove from heat and let it cool.
Step 2: Make the Meatloaf
Preheat your oven to 350Β°F (175Β°C). In a large mixing bowl, combine the ground beef, breadcrumbs, milk, egg, French onion soup mix, Worcestershire sauce, salt, and pepper. Add the cooled caramelized onions and garlic to the mixture. Mix everything together until fully combined.
Step 3: Shape and Bake
Transfer the meat mixture into a loaf pan and shape it into a loaf. Bake in the preheated oven for 50β60 minutes or until the meatloaf reaches an internal temperature of 160Β°F (71Β°C).
Step 4: Prepare the Glaze
While the meatloaf is baking, whisk together ketchup, Dijon mustard, brown sugar, soy sauce, and Worcestershire sauce in a small bowl. After baking for 40 minutes, remove the meatloaf from the oven and spread the glaze evenly over the top. Return it to bake for an additional 10β15 minutes until set and bubbly.
