Step‑by‑Step Instructions for French Onion Meatloaf
Step 1: Caramelize Onions
Start by thinly slicing two medium onions. In a large skillet, melt 2 tablespoons of butter over medium heat, add the onions, and sprinkle with a pinch of salt. Cook for 20–25 minutes, stirring occasionally, until the onions are golden brown and caramelized, enhancing the flavor of your French Onion Meatloaf. Once ready, remove the skillet from the heat and let the onions cool.
Step 2: Prepare Meat Mixture
In a spacious mixing bowl, combine 1 pound of ground beef with half of the cooled caramelized onions, 1 teaspoon of garlic powder, 1 teaspoon of onion powder, 1 teaspoon of dried thyme, and 2 tablespoons of Worcestershire sauce. Crack in 1 egg to bind the ingredients, followed by 1 cup of breadcrumbs. Mix gently until just combined, ensuring not to overmix for a tender meatloaf.
Step 3: Shape and Bake
Preheat your oven to 350°F (175°C) while you prepare the meatloaf. Transfer the meat mixture into a greased loaf pan, shaping it into a smooth loaf. Place the pan in the oven and bake for 45–50 minutes, or until the meatloaf reaches an internal temperature of 160°F (71°C). The edges should be a beautiful golden brown, hinting at the rich flavors inside.
Step 4: Final Touches
Bring out your French Onion Meatloaf and generously top it with the remaining caramelized onions and 1 cup of shredded Swiss cheese. Return the loaf to the oven and bake for an additional 10–15 minutes, or until the cheese is melted and bubbly, forming a delightful crust. This step will elevate your meatloaf with an irresistibly cheesy layer.
Step 5: Rest and Serve
Once baked to perfection, remove the meatloaf from the oven and allow it to rest for about 5 minutes. This helps retain its juices for a moist texture. After resting, slice your succulent French Onion Meatloaf and serve it warm with your choice of sides, like creamy mashed potatoes or a fresh salad, for a comforting meal.

French Onion Meatloaf Recipe FAQs
