Ingredients

Meatloaf Base:

  • 1 1/2 pounds ground beef
  • 1 cup breadcrumbs
  • 1/2 cup milk
  • 2 cloves garlic, minced
  • 1 egg, beaten
  • 2 tablespoons Worcestershire sauce
  • 1 tablespoon Dijon mustard
  • 1 teaspoon dried thyme
  • 1/2 teaspoon salt
  • 1/2 teaspoon black pepper

French Onion Mixture:

  • 2 large onions, thinly sliced
  • 2 tablespoons butter
  • 1/4 cup beef broth
  • 1 cup shredded Gruyère or Swiss cheese
Instructions

Step 1: Prepare the Onions

  1. Preheat your oven to 350°F (175°C).
  2. In a skillet over medium heat, melt the butter and add the thinly sliced onions.
  3. Stir occasionally and cook until caramelized and golden brown, about 20-25 minutes.
  4. Deglaze the pan with beef broth, scraping up any browned bits, and cook until absorbed. Set aside to cool.

Step 2: Make the Meatloaf Mixture

  1. In a large mixing bowl, combine ground beef, breadcrumbs, milk, minced garlic, beaten egg, Worcestershire sauce, Dijon mustard, dried thyme, salt, and pepper.
  2. Mix until just combined – do not overmix, or the meatloaf may become dense.

Step 3: Assemble the Meatloaf

  1. Fold in the caramelized onions and half of the shredded Gruyère cheese.
  2. Shape the mixture into a loaf and place it in a lightly greased baking dish.

Step 4: Bake

  1. Bake in the preheated oven for 1 hour, or until the internal temperature reaches 160°F (70°C).
  2. Sprinkle the remaining Gruyère cheese on top and bake for another 5-10 minutes, until melted and bubbly.

Step 5: Rest and Serve

  1. Allow the meatloaf to rest for 10 minutes before slicing.
  2. Serve with your favorite sides and enjoy!
Kitchen Equipment Needed
  • Large mixing bowl
  • Skillet
  • Spatula or wooden spoon
  • Measuring cups and spoons
  • Baking dish
  • Meat thermometer
Tips for Success
  • Caramelize the onions properly: Take your time to cook the onions slowly over medium heat. This enhances their natural sweetness and deepens the flavor of the meatloaf.
  • Use fresh breadcrumbs: Fresh breadcrumbs will help retain moisture better than dried ones.
  • Let the meatloaf rest: Resting the meatloaf before slicing prevents it from falling apart and allows the juices to redistribute evenly.
Variations and Substitutions
  • Meat Options: Swap ground beef with ground turkey or pork for a different twist.
  • Cheese Variations: Instead of Gruyère, try cheddar, mozzarella, or fontina.
  • Breadcrumb Alternatives: Use panko, crushed crackers, or almond flour for a low-carb version.
  • Extra Flavor Boost: Add 1 teaspoon of balsamic vinegar to the onions while caramelizing for extra depth.
How to Store and Reheat

Storing Leftovers:

  • Refrigerator: Store in an airtight container for up to 4 days.
  • Freezer: Wrap slices individually in plastic wrap and store in a freezer-safe bag for up to 3 months.

Reheating:

  • Oven: Warm at 300°F (150°C) for about 15 minutes.
  • Microwave: Heat in 30-second intervals until warm.
Best Side Dishes and Pairings

This French Onion Meatloaf pairs beautifully with:

  • Mashed potatoes or roasted potatoes
  • Steamed green beans or roasted Brussels sprouts
  • Crusty French bread to soak up any extra juices
  • Red wine like a Cabernet Sauvignon or Merlot for an elegant pairing
FAQ

Can I make this meatloaf ahead of time?

Yes! Assemble the meatloaf and store it in the fridge up to 24 hours before baking. Allow it to come to room temperature before placing it in the oven.

Can I use pre-cooked caramelized onions?

Absolutely! Store-bought caramelized onions can be a time-saver, but homemade onions will offer the freshest flavor.

How do I keep my meatloaf from being dry?

Make sure to use enough liquid ingredients, such as milk and Worcestershire sauce. Also, avoid overbaking by checking the internal temperature with a meat thermometer.

What can I do with leftover meatloaf?

Leftovers can be transformed into meatloaf sandwiches, crumbled into pasta sauce, or even used as a topping for baked potatoes.
