Ingredients You’ll Need
For the Meatloaf
1½–2 lb ground beef (or beef & pork blend)
2 large onions, thinly sliced
1 cup breadcrumbs
2 large eggs
¼ cup milk
1–2 tablespoons Worcestershire sauce
1 teaspoon salt
½ teaspoon black pepper
1 teaspoon dried thyme (optional)
1–2 tablespoons butter
1 tablespoon olive oil
1 cup shredded Swiss cheese + extra slices for topping
How to Make French Onion Meatloaf with Swiss Cheese
1. Caramelize the Onions
Heat butter and olive oil in a skillet over medium-low heat. Add sliced onions and a pinch of salt. Cook slowly for 25–30 minutes, stirring occasionally, until deeply golden and sweet. This step is essential for authentic French onion flavor.
2. Prepare the Meatloaf Mixture
In a large bowl, combine ground meat, breadcrumbs, eggs, milk, Worcestershire sauce, salt, pepper, thyme, and half of the caramelized onions. Mix gently until just combined—do not overmix.
3. Shape and Bake
Preheat oven to 375°F (190°C). Shape the mixture into a loaf and place on a parchment-lined baking sheet or in a greased loaf pan. Bake for 35 minutes.
4. Add Cheese and Finish Baking
Remove from oven, top with remaining caramelized onions and Swiss cheese slices. Return to oven and bake 10–15 minutes, until the cheese is melted and bubbly.
5. Rest and Serve
Let the meatloaf rest for 5–10 minutes before slicing to keep it juicy.
