Ingredients Notes

The magic of French Onion Meatloaf lies in its straightforward yet flavor-packed ingredients. Each element is carefully chosen to bring out the best in this dish.

Caramelized onions are the star of the show. Slowly cooked until golden brown and sweet, they infuse the meatloaf with rich, savory depth. Yellow onions work best here, as they caramelize beautifully and balance the dish with their natural sweetness.

Ground beef serves as the base of the meatloaf. I recommend using an 80/20 blend for the perfect combination of flavor and tenderness. If you prefer leaner meat, ground turkey or chicken can work, but the texture may differ slightly.

Gruyère cheese is the perfect addition, bringing its signature nutty flavor. You’ll mix some into the meatloaf and layer a bit on top for that irresistible melted finish. If Gruyère isn’t available, Swiss cheese or even mozzarella makes a great substitute.

Beef broth and Worcestershire sauce form the foundation of the glaze. Combined with a hint of ketchup, they create a savory-sweet topping that ties the dish together beautifully.

Finally, you’ll need breadcrumbs and eggs to bind everything together. Panko breadcrumbs keep the loaf light, while the eggs ensure it holds its shape as it bakes.

For equipment, a standard loaf pan works perfectly, but you can also free-form the meatloaf on a baking sheet for a more rustic presentation.

How to Make This French Onion Meatloaf

Creating this French Onion Meatloaf is a simple, rewarding process. Here’s how to bring it to life:

Start by caramelizing the onions. Heat a large skillet over medium heat, add a tablespoon of butter, and stir in thinly sliced yellow onions. Cook slowly, stirring often, until they turn deep golden brown—this can take about 25-30 minutes, but the flavor payoff is worth it.

While the onions cool, prepare the meatloaf mixture. In a large bowl, combine ground beef, an egg, breadcrumbs, Worcestershire sauce, a handful of shredded Gruyère, and half of the caramelized onions. Use your hands to mix everything gently—overmixing can make the meatloaf tough.

Shape the mixture into a loaf and place it in a greased loaf pan or on a baking sheet. Spread the remaining caramelized onions over the top, followed by a layer of shredded Gruyère.

Pop the loaf into a preheated 375°F oven and bake for 45-50 minutes, or until the internal temperature reaches 160°F. In the last 10 minutes, switch to broil to melt and brown the cheese topping.

Allow the meatloaf to rest for 5-10 minutes before slicing. This step is crucial for keeping all the juices locked in.

The result? A meatloaf so tender and flavorful, you’ll find yourself going back for seconds—and maybe even thirds!

Storage Options

One of the best things about French Onion Meatloaf is how well it stores and reheats. Here’s how to keep those leftovers tasting just as delicious:

For short-term storage, transfer the cooled meatloaf to an airtight container and refrigerate for up to 3-4 days. If you’re meal prepping, slice the meatloaf before storing to make reheating easier.

Planning to save some for later? Wrap individual slices tightly in plastic wrap, then place them in a freezer-safe container or bag. Frozen slices will keep for up to 3 months.

Reheating is a breeze. For the best results, warm the meatloaf in a 350°F oven, covered with foil, until heated through. In a hurry? A microwave works too—just use a lower power setting to prevent the meatloaf from drying out.

Variations and Substitutions

This French Onion Meatloaf is already a winner, but there are plenty of ways to tweak it to suit your preferences.

For a lighter version, swap the ground beef for ground turkey or chicken. Add an extra splash of beef broth to keep the mixture moist.

Prefer a different cheese? Try Swiss, provolone, or even sharp cheddar for a unique flavor twist. Each option brings its own character to the dish.

Vegetable lover? Mix in finely chopped mushrooms or spinach for added nutrition and texture. They’ll complement the caramelized onions beautifully.

Want a bolder flavor? Add a teaspoon of garlic powder or smoked paprika to the meat mixture. These spices enhance the savory notes without overpowering the dish.

Gluten-free? Use gluten-free breadcrumbs or crushed rice crackers in place of traditional breadcrumbs. You won’t even notice the difference!

No matter how you customize it, this recipe is your canvas. Feel free to experiment and make it your own.

Whether you’re serving it with mashed potatoes, roasted veggies, or a simple green salad, French Onion Meatloaf is the kind of dish that makes dinner feel extra special. Give it a try, and don’t be surprised when your family starts requesting it again and again!
