Ingredients for French Onion Meatloaf

• 2 tablespoons olive oil
• 3 large onions, thinly sliced
• 2 pounds ground beef (80-85% lean)
• 1 cup breadcrumbs or day-old bread, crumbled
• 1 cup shredded Gruyère cheese
• 1 large egg
• 2 tablespoons Worcestershire sauce
• 1 teaspoon thyme leaves
• 2 cloves garlic, minced
• Salt and pepper to taste

Ingredient Notes:

• Ground Beef: Using beef with a little fat (80-85%) ensures your meatloaf stays juicy and flavorful.
• Gruyère Cheese: This nutty, melty cheese is a classic in French onion soup and adds incredible richness to the dish.
• Caramelized Onions: Take your time here — slow-cooked onions bring a deep sweetness that balances the savory meat.

Step-by-Step Instructions

Follow these simple steps for perfect French Onion Meatloaf every time:

Step 1: Preheat the Oven

Set your oven to 350°F (175°C). Greasing your loaf pan in advance will make cleanup easier and ensure the meatloaf releases cleanly.

Step 2: Caramelize the Onions

Heat the olive oil in a wide skillet over medium-low heat. Add the thinly sliced onions and cook slowly, stirring occasionally, until the onions turn golden brown and caramelized. This process takes about 30–40 minutes but is essential for deep flavor. Patience pays off!

Step 3: Prepare the Meat Mixture

In a large mixing bowl, combine the ground beef, breadcrumbs, shredded Gruyère cheese, egg, Worcestershire sauce, thyme leaves, minced garlic, salt, and pepper. Gently mix everything together until just combined. Over-mixing can make the meatloaf dense, so mix with care.

Step 4: Shape the Meatloaf

Transfer the mixture into your greased loaf pan, pressing it gently to fill the pan evenly.

Step 5: Add the Caramelized Onions

Spread the caramelized onions over the top of the meatloaf, pressing them lightly so they adhere.

Step 6: Bake

Bake in the preheated oven for about 60 minutes, or until an internal thermometer reads 160°F (71°C). The crust will be golden, and the cheese inside melted to perfection.

Step 7: Rest and Serve

Let the meatloaf rest for about 10 minutes after baking. This helps the juices redistribute, making for moist, flavorful slices. Slice and serve warm!

Serving Suggestions

French Onion Meatloaf is wonderfully versatile. Here are a few sides to complete your meal:

• Creamy Mashed Potatoes: The rich, buttery flavor complements the savory meatloaf.
• Roasted Green Beans or Asparagus: Adds freshness and a slight crunch.

Tips for Success

• Don’t Rush the Onions: Caramelizing onions slowly develops their natural sweetness and depth of flavor.
• Use a Meat Thermometer: For perfect doneness, check that the internal temperature hits 160°F.
• Rest Before Slicing: Allowing the meatloaf to rest locks in the juices and makes for cleaner slices.
• Freeze for Later: This meatloaf freezes beautifully. Simply wrap tightly and store for up to 3 months.
