Ingredients You’ll Need

3 tablespoons butter: Used for caramelizing onions. Unsalted is preferable so you can control the saltiness.
2 large onions: Thinly sliced to become sweet and tender after cooking. Sweet onions, like Vidalia, work best.
2 pounds ground beef: The base of the meatloaf. Ground turkey or lean beef can be good substitutions for a lighter option.
2 eggs: These help bind the ingredients together for a firmer texture.
1/2 cup breadcrumbs: They absorb juices and keep the meatloaf moist. For a gluten-free version, use gluten-free breadcrumbs.
1 tablespoon Worcestershire sauce: Adds depth and umami flavor to the meat mixture.
1 teaspoon dried thyme: Enhances the overall flavor. Use fresh thyme for an even more aromatic taste.
1 teaspoon salt: Essential for seasoning the meat mixture.
1/2 teaspoon black pepper: Adds a subtle kick.
1 tablespoon flour: Thickens the onion sauce. Can be replaced with corn starch for gluten-free.
1 cup beef broth: For a flavorful sauce that enriches the finished dish.
1/2 cup Swiss cheese: Melts beautifully and provides a creamy texture.
4-5 slices provolone cheese: Topped over the meatloaf for a delicious, gooey finish.

How to Make French Onion Meatloaf

Preheat the oven: Set your oven to 350°F (175°C) to prepare for baking.
Caramelize the onions: Melt 2 tablespoons of butter in a large skillet over medium heat. Add the thinly sliced onions and cook them, stirring occasionally, for 20-25 minutes until they turn golden brown and beautifully caramelized. This is where all the magic happens with flavors! Remove half of the onions to set aside for the sauce.
Combine the meatloaf ingredients: In a large bowl, mix together 2 pounds of ground beef, 2 eggs, 1/2 cup breadcrumbs, 1 tablespoon Worcestershire sauce, 1 teaspoon dried thyme, 1 teaspoon salt, 1/2 teaspoon black pepper, and the remaining caramelized onions. Be sure to mix gently until just combined—overmixing can lead to a tough texture.
Shape and bake the meatloaf: Form the mixture into a loaf shape and place it into a baking dish or loaf pan. Bake it in the preheated oven for 45 minutes until it’s cooked through and the edges are beginning to crisp.
Make the sauce: While the meatloaf is baking, return the reserved onions to the skillet and add the remaining 1 tablespoon of butter. Let it melt, and stir in 1 tablespoon of flour, cooking for 1 minute while whisking. Gradually whisk in 1 cup of beef broth and let it simmer for 5-7 minutes, stirring occasionally until it thickens slightly. This sauce will add an extra layer of flavor!
Add the cheese: Once the meatloaf is done baking, take it out of the oven and sprinkle the top with 1/2 cup of shredded Swiss cheese followed by 4-5 slices of provolone cheese. Return it to the oven under the broiler for 3-5 minutes or until the cheese is bubbling and golden brown.
Slice and serve: Allow the meatloaf to rest for 5-10 minutes before slicing. Serve it with a generous spoonful of the onion sauce on top. You’re going to love the combination of flavors!

Storing & Reheating

To store the meatloaf, let it cool completely before placing it in an airtight container. Refrigerate it for up to 3-4 days. For longer storage, you can freeze the meatloaf wrapped tightly in foil or in a freezer-safe container for up to 3 months. When ready to enjoy, thaw it overnight in the fridge and reheat in the oven at 350°F (175°C) for 20-30 minutes until heated through. The texture may be slightly different, but a splash of beef broth can refresh the flavors!

Chef’s Helpful Tips

To keep your meatloaf moist, avoid overmixing the meat mixture—just blend until combined.
Use room temperature eggs for better binding, which leads to a tender loaf.
If the top of your meatloaf is browning too quickly, drape a piece of tin foil over it to prevent burning.
Play with spices such as oregano or basil for an added depth of flavor.
This recipe is perfect for preparing ahead of time. You can assemble it, cover it, and store it in the fridge until ready to bake.

There’s something truly wonderful about enjoying a meal that brings comfort and warmth. This French Onion Meatloaf is a delightful mashup of flavors that gives a nod to both classic meatloaf and French onion soup—a combination that I can’t get enough of! Each slice, topped with sauce, promises a mouthwatering experience you’ll want to repeat.

What can I serve with French Onion Meatloaf?

This delectable meatloaf pairs well with creamy mashed potatoes, steamed green beans, or a fresh garden salad. The delicious onion sauce complements any side you choose!
