Ingredients You’ll Need
Here’s everything required to make the best French Onion Meatloaf at home:
For the Meatloaf:
- 2 lbs ground beef (80/20 for the best texture)
- 1 cup caramelized onions (see below for instructions)
- ½ cup breadcrumbs (Italian-style or plain)
- 2 eggs (beaten)
- 1 tablespoon Worcestershire sauce
- ½ teaspoon garlic powder
- ½ teaspoon onion powder
- ½ teaspoon black pepper
- 1 teaspoon salt
- ½ cup shredded mozzarella cheese
- ½ cup shredded Gruyère cheese
For the Caramelized Onions:
- 2 large onions (thinly sliced)
- 2 tablespoons butter
- 1 tablespoon olive oil
- 1 teaspoon sugar
- ½ teaspoon salt
- ¼ cup beef broth (optional, for extra richness)
For the Topping:
- 1 cup shredded mozzarella cheese
- ½ cup shredded Gruyère cheese
- Fresh parsley (for garnish)
Step-by-Step Instructions
Step 1: Caramelize the Onions
- Heat butter and olive oil in a large skillet over medium-low heat.
- Add sliced onions, sprinkle with sugar and salt, and cook slowly for about 25-30 minutes, stirring occasionally.
- Once onions turn golden brown, deglaze the pan with beef broth (if using) and cook for another 5 minutes.
- Remove from heat and let cool slightly before adding to the meatloaf mixture.
Step 2: Prepare the Meatloaf Mixture
- Preheat your oven to 375°F. Grease a loaf pan or line it with parchment paper.
- In a large mixing bowl, combine ground beef, caramelized onions, breadcrumbs, eggs, Worcestershire sauce, garlic powder, onion powder, salt, and black pepper.
- Gently mix until just combined—do not overmix, or the meatloaf may become tough.
- Fold in the shredded mozzarella and Gruyère cheese for extra moisture and flavor.
Step 3: Shape and Bake
- Transfer the mixture to the prepared loaf pan and shape it evenly.
- Bake in the preheated oven for 40-45 minutes, or until the internal temperature reaches 160°F.
Step 4: Add the Cheese Topping
- Remove the meatloaf from the oven and sprinkle shredded mozzarella and Gruyère cheese on top.
- Return to the oven and broil for 3-5 minutes, until the cheese is bubbly and slightly golden.
- Let it rest for about 10 minutes before slicing to allow the juices to redistribute.
