Ingredients You’ll Need

For the Meatloaf:

  • 2 lbs ground beef (80/20 for juiciness)
  • 1 large egg
  • 1 cup breadcrumbs
  • 1 packet French onion soup mix (or homemade equivalent)
  • 1 tsp Worcestershire sauce
  • 1/4 cup milk
  • 1 cup shredded mozzarella or Gruyère cheese (optional, for center filling)
  • Salt & black pepper to taste

For the Onion Topping:

  • 2 large yellow onions, thinly sliced
  • 1 tbsp olive oil
  • 1 tbsp butter
  • Pinch of salt
  • 1/2 tsp sugar (helps caramelize)

For the Glaze:

  • 1 tbsp brown sugar
  • 1 tsp Dijon mustard

How to Make French Onion Meatloaf

Step 1: Caramelize the Onions

In a skillet, heat olive oil and butter over medium heat. Add sliced onions, salt, and sugar. Cook for 25–30 minutes, stirring occasionally, until onions are deeply golden and soft.

Step 2: Mix the Meatloaf

In a large bowl, combine ground beef, egg, breadcrumbs, French onion soup mix, Worcestershire sauce, milk, salt, and pepper. Mix just until combined—don’t overwork the meat.

Step 3: Stuff and Shape

Optional: Divide the meat mixture in half. Flatten one half into a loaf shape, place cheese in the center, and top with the other half. Seal the edges to keep the cheese inside.

Step 4: Top and Bake

Preheat oven to 375°F (190°C). Place meatloaf in a baking dish. Spread caramelized onions on top. In a small bowl, mix glaze ingredients and brush over the onions. Bake for 50–60 minutes or until internal temperature reaches 160°F (71°C).

Step 5: Rest and Serve

Let the meatloaf rest for 10 minutes before slicing. Serve with mashed potatoes or roasted vegetables for the ultimate comfort meal.
