Ingredients Notes

The magic of this French Onion Meatloaf lies in its carefully selected ingredients, each adding its unique flavor and texture to the dish.

The star of the recipe is ground beef. For the best results, choose a blend with an 80/20 fat ratio. This ensures your meatloaf stays juicy without being overly greasy.

Caramelized onions provide the rich, sweet-savory flavor that defines French onion soup. While it takes a bit of patience to cook them low and slow, the payoff is absolutely worth it.

A mix of panko breadcrumbs and eggs binds the meat mixture together, giving the meatloaf its tender structure. Panko adds a slightly lighter texture compared to traditional breadcrumbs.

Gruyère cheese is the perfect choice for this dish, as it melts beautifully and delivers that classic French onion flavor. However, you can substitute it with Swiss or mozzarella if needed.

Beef broth and a touch of Worcestershire sauce are the secret ingredients that keep the meatloaf moist and infuse it with deep, savory notes.

For this recipe, you’ll also need a loaf pan, a skillet for caramelizing the onions, and a mixing bowl.

How To Make This French Onion Meatloaf

Creating this delicious French Onion Meatloaf is easier than you might think. Follow these simple steps for a show-stopping dish.

Start by caramelizing your onions. Heat a large skillet over medium heat with a tablespoon of butter. Add thinly sliced onions and a pinch of salt, then cook slowly, stirring occasionally, until they’re golden and sweet. This can take about 25-30 minutes, so be patient.

While the onions cook, preheat your oven to 375°F and prepare your meatloaf mixture. In a large bowl, combine ground beef, panko breadcrumbs, eggs, Worcestershire sauce, and a splash of beef broth. Mix gently until everything is evenly combined.

Once the onions are ready, let them cool slightly before mixing half of them into the meat mixture. Reserve the rest for topping. Transfer the meat mixture to a loaf pan, pressing it gently into an even layer.

Bake the meatloaf for 30 minutes. While it cooks, shred your Gruyère cheese. After 30 minutes, spread the reserved caramelized onions over the top of the meatloaf, followed by the cheese. Return it to the oven for another 15-20 minutes, or until the cheese is melted and bubbly.

Let the meatloaf rest for 5-10 minutes before slicing. This allows the juices to redistribute, ensuring every slice is moist and flavorful.

Storage Options

French Onion Meatloaf stores beautifully, making it a great option for meal prep or leftovers.

To refrigerate, transfer cooled slices to an airtight container and store them for up to 4 days. Reheat in the oven or microwave until warmed through.

For longer storage, freeze individual slices wrapped in plastic wrap and foil. They’ll keep in the freezer for up to 3 months. When ready to eat, thaw in the refrigerator overnight and reheat.

If reheating an entire meatloaf, cover it with foil and bake at 350°F for 20-30 minutes to prevent it from drying out.

Variations and Substitutions

This recipe is highly adaptable, allowing you to customize it to suit your tastes or dietary needs.

For a leaner version, swap out ground beef for ground turkey or chicken. Just be sure to add a bit of extra moisture, such as a tablespoon of olive oil or additional broth.

Want to experiment with cheese? While Gruyère is classic, cheddar or provolone works beautifully, adding a slightly different flavor profile.

If you’re a fan of mushrooms, finely chop and sauté them alongside the onions. They’ll add an earthy depth to the dish.

To make this meatloaf gluten-free, substitute the panko breadcrumbs with gluten-free breadcrumbs or crushed gluten-free crackers.

Feeling adventurous? Add a teaspoon of fresh thyme or a splash of sherry to the caramelized onions for an extra gourmet touch.

French Onion Meatloaf is a dish that’s as comforting as it is versatile. Once you’ve tried it, don’t be surprised if it becomes a regular in your recipe rotation!
