Ingredients Notes

The magic of this French Onion Meatloaf comes from its carefully chosen ingredients. Each one contributes to the dish’s incredible flavor and texture. Here's a closer look:

Ground Beef: I recommend using an 80/20 blend for the perfect balance of juiciness and flavor. If you prefer leaner meat, you can go with 90/10, but keep in mind it may be a bit drier.
Onions: The key to this dish is beautifully caramelized onions. Yellow onions work best because they turn sweet and golden as they cook. Be patient with this step—it’s worth it!
Cheese: Gruyère is the classic choice for that French onion soup vibe. Its nutty, melty goodness ties the flavors together. Swiss or mozzarella can work in a pinch, but Gruyère truly shines here.
Breadcrumbs and Eggs: These binders are essential for holding the meatloaf together while keeping it tender. I prefer using seasoned breadcrumbs for added flavor.
Beef Broth: A splash of beef broth in the caramelized onions ensures they’re extra moist and flavorful. It also enhances the "French onion" taste.
Worcestershire Sauce: This ingredient adds a savory depth to the meat mixture, balancing the richness of the onions and cheese.

You’ll also need a loaf pan for shaping the meatloaf and foil to cover it during baking. These simple tools make prep and cleanup a breeze.

How To Make This French Onion Meatloaf

Creating this showstopping French Onion Meatloaf is easier than you might think. Let me guide you through each step to ensure success.

Step 1: Caramelize the Onions

Start by slicing your onions thinly. Heat a large skillet over medium heat and add a couple of tablespoons of butter. Once melted, toss in the onions with a pinch of salt. Stir occasionally, letting them cook slowly for about 20-25 minutes, until they’re soft, golden, and caramelized. Add a splash of beef broth during the last 5 minutes to deglaze the pan and enhance the flavor.

Step 2: Prepare the Meat Mixture

In a large mixing bowl, combine ground beef, breadcrumbs, eggs, Worcestershire sauce, and a portion of the caramelized onions (save some for topping). Mix gently with your hands until just combined—overmixing can make the meatloaf tough.

Step 3: Assemble the Meatloaf

Preheat your oven to 375°F (190°C). Grease a loaf pan or line it with parchment paper for easy removal. Press half of the meat mixture into the pan, creating a slight indentation in the center. Fill this with half of the Gruyère cheese, then layer the remaining meat mixture on top, sealing the edges.

Step 4: Bake and Finish

Cover the pan with foil and bake for 40 minutes. Remove the foil, top the meatloaf with the reserved caramelized onions and the remaining cheese, and bake uncovered for another 15-20 minutes, or until the cheese is bubbly and the internal temperature reaches 160°F (71°C).

Step 5: Rest and Serve

Let the meatloaf rest for 10 minutes before slicing. This allows the juices to redistribute, ensuring every slice is tender and juicy. Serve with a side of mashed potatoes or a crisp green salad for a complete meal.

Storage Options

This French Onion Meatloaf stores beautifully, making it ideal for meal prep or leftovers.

Refrigerator: Wrap the cooled meatloaf tightly in foil or store slices in an airtight container. It will keep for up to 4 days.
Freezer: Slice the meatloaf and wrap each piece in plastic wrap, then place in a freezer-safe bag. Freeze for up to 3 months. Thaw overnight in the fridge before reheating.
Reheating: Warm slices in a 350°F (175°C) oven for 10-15 minutes or microwave in 30-second intervals until heated through.

Variations and Substitutions

This recipe is endlessly adaptable. Here are some ideas to make it your own:

Different Proteins: Swap out the ground beef for ground turkey, chicken, or pork for a lighter option.
Cheese Options: Try cheddar, provolone, or even pepper jack for a unique twist.
Gluten-Free: Use gluten-free breadcrumbs or crushed gluten-free crackers as a binder.
