Ingredients Notes

The magic of this recipe lies in its balance of simple ingredients and bold flavors. Each element contributes to the dish’s unique appeal.

Ground Beef: For the best texture and flavor, opt for 80/20 ground beef. The fat content keeps the meatloaf moist and juicy as it bakes.
Onions: Thinly sliced yellow onions are caramelized to golden perfection. This step is key to achieving the rich, sweet-savory flavor that defines the dish.
Beef Broth: Adds moisture and a subtle umami flavor. You can use low-sodium broth to control the saltiness.
Breadcrumbs: These help bind the meatloaf and create a tender texture. Use plain or seasoned breadcrumbs based on your preference.
Gruyère Cheese: The nutty, melty Gruyère pairs beautifully with the onions. Swiss cheese works as an excellent substitute if needed.
Eggs: Essential for binding the mixture and ensuring the meatloaf holds its shape.
Worcestershire Sauce: A splash of this pantry staple enhances the umami and ties the flavors together.

You'll also need a loaf pan for shaping the meatloaf and a skillet for caramelizing the onions.

How To Make This French Onion Meatloaf

Creating this masterpiece is simpler than you might think. Follow these steps for a perfect result every time.

Caramelize the Onions
Start by heating a skillet over medium heat with a tablespoon of butter and olive oil. Add thinly sliced onions and cook slowly, stirring occasionally, until they turn a deep golden brown. This process takes about 25-30 minutes but is worth every second. Add a splash of beef broth to deglaze the pan and scrape up the flavorful bits. Set aside to cool.
Prepare the Meat Mixture
In a large mixing bowl, combine ground beef, breadcrumbs, eggs, Worcestershire sauce, a portion of the caramelized onions, and a bit of the cooled broth. Mix gently to avoid overworking the meat, which can make it tough.
Shape and Bake
Transfer the meat mixture to a loaf pan or shape it by hand onto a baking sheet. Bake in a preheated oven at 375°F (190°C) for 40 minutes.
Add the Cheese
Remove the meatloaf from the oven and top with the remaining caramelized onions and slices of Gruyère cheese. Return to the oven and bake for an additional 10-15 minutes, or until the cheese is bubbly and golden.
Rest and Serve
Allow the meatloaf to rest for 10 minutes before slicing. This helps the juices redistribute for a moist, flavorful bite every time.

Storage Options

Refrigerate: Store leftovers in an airtight container for up to 4 days.
Freeze: Wrap individual slices in plastic wrap, then place them in a freezer-safe bag. Freeze for up to 3 months.
Reheat: Warm in the oven at 350°F (175°C) or microwave until heated through. Add a fresh layer of cheese for extra indulgence.
