What Kind of Cheese Is Best for French Onion Meatloaf?

For the signature flavor and melty texture, Gruyère is the classic choice. It melts beautifully and has that nutty depth you associate with French onion soup. Swiss cheese or provolone also work well if you’re looking for a milder taste. Just make sure whatever cheese you choose has a smooth melt and rich flavor.

How To Make the Irresistible French Onion Meatloaf

Step 1: Caramelize the Onions

Slice sweet onions thinly and cook them slowly over medium heat with a bit of butter until they’re deeply golden and sweet. This can take up to 30 minutes but is key for that classic flavor.

Step 2: Prepare the Meat Mixture

In a large bowl, combine ground beef, eggs, breadcrumbs, Worcestershire sauce, minced garlic, chopped thyme, salt, pepper, and half of your caramelized onions. Mix until just combined—don’t overwork the meat.

Step 3: Shape and Bake

Form the meat mixture into a loaf on a parchment-lined baking sheet or place it in a loaf pan. Bake at 375°F (190°C) for about 40 minutes.

Step 4: Top with Onions and Cheese

Remove the meatloaf from the oven and layer the remaining caramelized onions and a generous helping of Gruyère or Swiss cheese on top. Return to the oven for another 10-15 minutes until the cheese is melted and bubbly.

Step 5: Rest and Serve

Let the meatloaf rest for 10 minutes before slicing. This helps retain the juices and makes slicing easier.
