Step-by-Step Instructions on How to Make French Onion Meatloaf

Step 1: Caramelize the Onions

In a large skillet, heat butter and olive oil over medium heat. Add onions, salt, pepper, thyme, and sugar (if using). Cook slowly, stirring often, for 25–30 minutes, until onions are soft, golden brown, and sweetly fragrant.

Remove from heat and set aside.

Step 2: Preheat the Oven

Preheat oven to 375°F (190°C). Grease or line a loaf pan with parchment paper.

Step 3: Mix the Meatloaf

In a large bowl, combine ground beef, breadcrumbs, milk, eggs, Worcestershire sauce, garlic powder, onion powder, salt, and pepper.

Fold in half of the caramelized onions and 1 cup cheese. Mix until just combined — don’t overwork the meat!

Step 4: Shape and Bake

Form the mixture into a loaf and place in the prepared pan. Bake for 45–55 minutes, or until the internal temperature reaches 160°F (71°C).

Step 5: Make the French Onion Gravy

While the meatloaf bakes, return the remaining onions to the skillet. Add butter and sprinkle with flour. Stir for 1 minute to form a roux.

Slowly whisk in beef broth and simmer until thickened into a rich, glossy onion gravy.

Step 6: Top and Broil

Once the meatloaf is cooked, spoon the gravy over the top and sprinkle with extra cheese. Broil for 2–3 minutes, just until the cheese is melted and bubbly.

Step 7: Rest and Serve

Let rest for 10 minutes before slicing. Serve with a generous drizzle of onion gravy over each piece.
