Ingredients for French Onion Meatloaf

1 tablespoon olive oil
2 large yellow onions, thinly sliced
1 teaspoon sugar
1/4 teaspoon salt
2 pounds ground beef
1/2 cup breadcrumbs
1/4 cup milk
2 large eggs
1 teaspoon Worcestershire sauce
1 teaspoon garlic powder
1/2 teaspoon dried thyme
1 cup shredded Gruyère or Swiss cheese
1/4 cup ketchup
2 tablespoons beef broth (optional for glaze)

Step-by-Step Recipe: French Onion Meatloaf

1. Caramelize the Onions

Heat olive oil in a large skillet over medium heat.
Add the sliced onions, sugar, and salt, stirring to coat.
Cook the onions, stirring occasionally, for 20–25 minutes until they are golden brown and caramelized. Set aside to cool slightly.

2. Prepare the Meatloaf Mixture

In a large bowl, combine the ground beef, breadcrumbs, milk, eggs, Worcestershire sauce, garlic powder, dried thyme, and half of the caramelized onions. Mix until just combined. Avoid overmixing to keep the meatloaf tender.

3. Assemble the Meatloaf

Preheat your oven to 375°F (190°C).
Transfer the meat mixture to a loaf pan or shape it into a loaf on a baking sheet lined with parchment paper.
Create a shallow well in the center of the meatloaf and fill it with the shredded Gruyère cheese. Press the meat mixture gently to seal the cheese inside.

4. Add the Glaze

In a small bowl, mix the ketchup and beef broth (if using) for a rich glaze. Spread it evenly over the top of the meatloaf.

5. Bake

Bake the meatloaf for 45–50 minutes, or until the internal temperature reaches 160°F (71°C).
During the last 10 minutes of baking, top the meatloaf with the remaining caramelized onions for added flavor and presentation.

Tips for the Perfect French Onion Meatloaf

1. Perfectly Caramelize the Onions

Patience is key when caramelizing onions. Cook them slowly over medium heat, stirring occasionally, to bring out their natural sweetness and achieve a deep golden color.

2. Don’t Overmix the Meat

Overmixing the meat mixture can result in a dense meatloaf. Mix gently until all the ingredients are just combined for a tender and juicy result.

3. Use High-Quality Cheese

Gruyère cheese melts beautifully and adds a nutty, creamy flavor. If unavailable, use Swiss cheese or even provolone for a similar effect.
