What Makes French Onion Meatloaf So Special?

The secret lies in its layering of textures and flavors. You’re not just getting a meatloaf—you’re getting sweet, slow-cooked onions, melty Swiss cheese, and a beefy loaf that stays juicy inside. It balances richness with a bite of sharpness from the cheese and sweetness from the onions.

Ingredients for the French Onion Meatloaf with Melted Swiss

Ground Beef – A lean mix provides structure and richness. Go with 80/20 for perfect moisture.

Onions – Sweet yellow onions are the hero here, slow caramelized to enhance their natural sugars.

Swiss Cheese – Adds creamy, nutty depth. Melts beautifully over the warm meatloaf.

Breadcrumbs – Helps bind the loaf and soak up juices.

Eggs – Essential for structure and binding the ingredients together.

Garlic and Thyme – For that earthy, aromatic flavor profile that French onion lovers crave.

Beef Broth – Adds umami depth when simmering the onions.

Worcestershire Sauce – For savory punch and slight tang.

Butter – Richness to cook down those onions to golden perfection.

How To Make the French Onion Meatloaf with Melted Swiss

Step 1: Caramelize the Onions

In a skillet over medium-low heat, melt butter and add sliced onions. Stir occasionally for 25-30 minutes until deep golden brown. Add garlic and thyme in the last 5 minutes. Pour in beef broth and Worcestershire, let it simmer, then remove from heat.

Step 2: Prep the Meatloaf Mix

In a large bowl, combine ground beef, breadcrumbs, eggs, a spoonful of the caramelized onion mix, salt, and pepper. Mix until just combined—don’t overwork it.

Step 3: Form and Bake

Shape the meat mixture into a loaf on a parchment-lined baking sheet. Bake at 375°F (190°C) for 35-40 minutes.

Step 4: Add Swiss and Onions

Remove from the oven, layer Swiss cheese on top, and pile the rest of the caramelized onions over it. Return to oven for another 10 minutes, or until cheese melts and begins to brown.

Step 5: Rest and Slice

Let the meatloaf rest for 5-10 minutes to hold its shape. Slice and serve with extra pan juices or gravy, if desired.

Serving and Storing French Onion Meatloaf

Serve warm straight out of the oven. Store any leftovers in an airtight container in the fridge for up to 4 days. Reheat gently in the oven or microwave with a splash of broth to keep it moist.

To freeze, wrap slices in foil and place in a freezer-safe bag. Great for meal prep or make-ahead dinners.
