• Olive Oil (1 tablespoon): Helps caramelize the onions, adding a fruity depth you just can’t skip.
• Yellow Onions, thinly sliced (2 large): The star! These develop a sweet, savory caramelization that defines the dish.
• Butter (1 tablespoon): Combines with the oil to give onions their iconic richness.
• Salt (1 teaspoon): Essential for unlocking those sweet onion flavors and seasoning the meat.
• Black Pepper (1/2 teaspoon): Adds just the right touch of subtle heat.
• Worcestershire Sauce (1 tablespoon): Brings tang and umami that make each bite pop.

• Garlic Powder (1/2 teaspoon): Provides gentle, savory complexity without overpowering the onions.
• Fresh Thyme Leaves (2 teaspoons) or Dried Thyme (1 teaspoon): The natural, earthy touch livens up the whole loaf.
• Breadcrumbs (1 1/4 cups): Hold everything together and give the meatloaf its soft, comforting texture.
• Eggs (2 large): Key for binding all the deliciousness into sliceable perfection.

How to Make French Onion Meatloaf

Step 1: Caramelize the Onions

Start by warming the olive oil and butter in a skillet over medium heat. Pile in the sliced onions, sprinkle with salt and pepper, and settle in for some patient stirring. Let the onions slow-cook for about 20 to 25 minutes, stirring occasionally, until they become gorgeously golden-brown and deeply fragrant. This caramelization is where that signature French onion flavor really springs to life, so don’t rush this step—it’s worth every minute!

Step 2: Add Flavor and Broth

Once your onions are sweet and deeply colored, stir in the Worcestershire sauce, garlic powder, and thyme, ensuring the seasonings coat every strand of onion. Pour in the beef broth and let everything simmer together for about 5 minutes, or until most of the liquid has been absorbed. This melds all those savory flavors together and gives the onions a luscious, almost jammy consistency. Remove from the heat and let the mixture cool for a few minutes so it doesn’t scramble your eggs in the next step.

Step 3: Mix the Meatloaf Base

In a large mixing bowl, combine your ground beef, breadcrumbs, eggs, half of the cooled onion mixture, and all of the Gruyère or Swiss cheese. Use your hands or a sturdy spoon to mix everything together until just blended—try not to overwork it, as that can make the meatloaf tough. You’re aiming for a mixture that’s rich, cohesive, and full of savory aroma.

Step 4: Shape and Top Your Loaf

Transfer the meatloaf base into your prepared loaf pan, pressing gently to shape it evenly. Spoon the remaining onion mixture over the top, spreading it from edge to edge. Sprinkle the mozzarella cheese over everything, making sure you cover it for maximum melt and cheese pull factor.

Step 5: Bake to Perfection

Pop your French Onion Meatloaf into the preheated 350°F oven and bake for 55 to 65 minutes, or until the internal temperature reaches 160°F. Those cheesy, oniony flavors will fill your kitchen with mouthwatering aromas. Once baked, let it rest for about 10 minutes before slicing—this keeps the slices neat and juicy.

How to Serve French Onion Meatloaf

Garnishes

A sprinkle of fresh thyme or parsley brightens each slice, and a few extra shavings of Gruyère right before serving add a lightly nutty burst of flavor. If you want to get extra fancy, a drizzle of the pan juices or a quick reduction of beef broth elevates your meatloaf even more.

Side Dishes

French Onion Meatloaf pairs beautifully with creamy mashed potatoes or roasted root veggies, both of which soak up the savory juices. Light, crisp salads with a tangy vinaigrette also strike a nice balance, and a chunk of crusty bread lets you get every last bit of caramelized onion from your plate.

Creative Ways to Present

Try slicing the meatloaf into thick pieces and serving them “open-face” on toasted baguette rounds, topped with extra cheese and slipped under the broiler for a minute. Or, make mini meatloaf muffins for a fun, hand-held option that’s perfect for parties or lunchboxes.

Make Ahead and Storage

Storing Leftovers

Keep leftover French Onion Meatloaf in an airtight container in the fridge for up to four days. The flavors continue to meld, making the next day’s lunch or dinner even more delicious.

Freezing

To freeze, wrap individual slices or the whole cooled loaf tightly in foil, then place in a freezer bag. It’ll stay tasty for up to three months. Thaw overnight in the refrigerator before reheating.

Reheating

Warm up slices in a 325°F oven covered with foil for about 15-20 minutes, or until heated through. For best results, add a splash of beef broth to keep everything moist, or microwave slices gently until steaming.
