Serve it with creamy mashed potatoes to soak up the juices, or pair it with a crisp green salad for a fresh contrast. Every bite delivers that soul-warming combination of sweet onions, savory meat, and molten cheese—the kind of flavors that make you close your eyes for just a second before going in for another forkful.

Ingredients for the Meatloaf Base

For the Meatloaf:

• 1 ½ lbs ground beef (or mix with turkey/pork for variety)
• 1 cup caramelized onions (from below)
• 2 cloves garlic, minced
• 1 egg
• ½ cup breadcrumbs
• 2 tbsp Worcestershire sauce
• 1 tsp salt
• ½ tsp black pepper

For the French Onion Topping:

• 1 cup caramelized onions (yes, you’ll make extra)
• ¾ cup shredded Swiss or Gruyère cheese
• ½ cup beef broth or French onion soup concentrate

How to Make French Onion Meatloaf Step-by-Step

1. Caramelize the Onions

This is the foundation of your flavor—get it right and everything else shines. Start with a heavy-bottomed skillet (cast iron or stainless works best) over medium-low heat. Add 1 tablespoon butter and 1 tablespoon neutral oil (the oil helps prevent the butter from burning). Once the butter melts and shimmers, add your sliced onions.

Stir every couple of minutes, letting the onions sweat and slowly develop color. If they start to stick, splash in a tablespoon of water or broth to deglaze. After 20–25 minutes, you should see deep golden-brown onions that are soft, sweet, and jammy—no bitterness, no char. (Most people turn the heat up and scorch them—don’t fall into that trap.)

2. Prepare the Meatloaf Mixture

In a large mixing bowl, combine:

• Ground meat of choice
• About half of your caramelized onions
• Garlic, egg, breadcrumbs, Worcestershire sauce, salt, and pepper

Here’s the trick: Use your hands, not a spoon, and mix gently just until everything is evenly combined. Overworking the mixture will break down the protein structure and make your meatloaf dense and dry. Think “fold and press,” not “knead like bread.

3. Shape and Bake

Shape the meat into a loaf—about 8 inches long and 4 inches wide—and place it on a parchment-lined baking sheet (better browning) or into a loaf pan (neater shape, juicier center). Bake at 350°F for 45–50 minutes.

You’re not guessing here—use an instant-read thermometer and pull it when the center hits 160°F. This ensures juicy, safe-to-eat meat without overcooking.

4. Add the French Onion Topping

Remove the meatloaf from the oven, spread the remaining caramelized onions over the top, and sprinkle generously with shredded Swiss or Gruyère. Pour ½ cup beef broth or French onion soup concentrate over the loaf—this adds moisture and amps up the flavor.

Return to the oven for 10–15 minutes until the cheese is fully melted, bubbling, and golden at the edges. (If you want extra browning, hit it under the broiler for the last 1–2 minutes—but watch it closely.)

5. Serve and Enjoy

Transfer the meatloaf to a cutting board and let it rest for at least 5 minutes. This step is non-negotiable—the juices redistribute into the meat instead of running out onto your plate. Slice with a sharp knife and serve warm.

Preparation Time

• Prep: 15 minutes
• Cook: 1 hour 10 minutes
• Total: 1 hour 25 minutes

How to Serve

• Mashed Potatoes – Creamy, buttery potatoes are the perfect partner.
• Roasted Vegetables – Carrots, parsnips, or Brussels sprouts bring natural sweetness.
• Simple Salad – A tangy vinaigrette cuts through the richness.

Additional Tips

• Make ahead up to 24 hours and bake when ready.
• Double the recipe—this freezes beautifully.
• Spice it up with cayenne or Dijon mustard.
• Try cheddar, provolone, or even mozzarella for a different cheese profile.
