Ingredients
  

For the Meatloaf
  • 1 lb Ground Beef can use ground turkey for a leaner option

  • 2 tbsp Dijon Mustard use yellow mustard for a milder flavor
  • 1 tsp Dried Thyme fresh thyme will enhance the taste further
  • 1 tsp Salt

Method
 

Step‑by‑Step Instructions
  1. Preheat your oven to 350°F (175°C).
  2. In a large skillet, melt a tablespoon of butter over medium heat. Add the sliced onions and cook them slowly for about 20–25 minutes, stirring occasionally until they are golden brown.
  3. In a large mixing bowl, combine the ground beef with breadcrumbs, milk, minced garlic, Worcestershire sauce, Dijon mustard, dried thyme, salt, and black pepper. Mix gently until just combined.
  4. Fold the cooled caramelized onions into the meat mixture along with half of the Gruyère cheese.
  5. Transfer the mixture to a greased baking dish and shape it into a loaf. Bake for about 1 hour.
  6. Remove the meatloaf from the oven and sprinkle the remaining Gruyère cheese on top. Bake for an additional 5–10 minutes until the cheese is melted.
  7. Let the meatloaf rest for at least 10 minutes before slicing and serving.
