Ingredients Notes

The magic of this French Onion Meatloaf lies in its carefully chosen ingredients. Each one plays a role in creating the perfect balance of flavors.

Ground Beef: Choose a blend with a little fat, like 85/15, to keep your meatloaf moist and flavorful. Ground turkey can be used as a leaner alternative.
Onions: Caramelized onions are the star of the show. Yellow onions work best for their natural sweetness, but you can use white onions in a pinch.
Breadcrumbs: These help bind the meatloaf together. Panko breadcrumbs provide a light texture, but regular breadcrumbs work just as well.
Gruyère Cheese: This nutty, melty cheese is the perfect topping. If Gruyère isn’t available, Swiss cheese or provolone are excellent substitutes.
Beef Broth: A splash of broth adds moisture and a subtle beefy flavor. For an extra French onion soup vibe, opt for low-sodium beef consommé.
Worcestershire Sauce: This ingredient adds depth and umami, elevating the meatloaf to restaurant-quality flavor.

Special Equipment: A loaf pan works great for shaping the meatloaf, but you can also use a sheet pan if you prefer a free-form style.

How To Make This French Onion Meatloaf

Creating this French Onion Meatloaf is easier than you might think. Follow these steps for perfect results every time.

Caramelize the Onions
Start by slicing your onions thinly. Heat a large skillet over medium heat and add a tablespoon of butter. Once melted, toss in the onions and cook slowly, stirring occasionally, until they’re golden brown and sweet. This process takes about 20-25 minutes but is worth every second.
Prepare the Meat Mixture
In a large mixing bowl, combine ground beef, breadcrumbs, a beaten egg, half of your caramelized onions, and seasonings like salt, pepper, and a splash of Worcestershire sauce. Mix gently to avoid overworking the meat.
Shape and Bake
Transfer the mixture into a loaf pan, pressing it down evenly. Bake at 375°F (190°C) for 45 minutes. While it bakes, warm up the remaining caramelized onions with a bit of beef broth.
Add the Cheese
Remove the meatloaf from the oven and spread the reserved onions on top. Layer with slices of Gruyère cheese and return to the oven for another 10-15 minutes, or until the cheese is melted and bubbly.
Rest and Serve
Let the meatloaf rest for 5-10 minutes before slicing. This helps it retain its juices and makes for cleaner slices. Serve with mashed potatoes or a crisp green salad for a complete meal.

Storage Options

This French Onion Meatloaf is just as good the next day, making it perfect for leftovers.

Refrigerator: Store leftovers in an airtight container for up to 4 days.
Freezer: Wrap individual slices in plastic wrap, then foil, and freeze for up to 3 months.
Reheating: Warm slices in the oven at 350°F (175°C) or microwave until heated through. Add a touch of broth to prevent dryness.

Variations and Substitutions

This recipe is wonderfully versatile, allowing you to tailor it to your preferences or dietary needs.

Make it Gluten-Free: Use gluten-free breadcrumbs and double-check that your Worcestershire sauce is gluten-free.
Add Vegetables: Sneak in some finely chopped mushrooms or grated zucchini for extra nutrients.
Try a Different Protein: Swap out the beef for ground turkey, chicken, or a meatloaf mix for a lighter twist.
Change the Cheese: If Gruyère isn’t your favorite, try mozzarella, cheddar, or even a mix of cheeses for a unique flavor.
Spice it Up: Add a pinch of cayenne or smoked paprika to the meat mixture for a little heat.

Experiment with these variations to make the recipe your own – the possibilities are endless!
