How To Make Cheesy French Onion Meatloaf

Step 1: Caramelize The Onions

Heat butter in a large skillet over medium-low heat.

stirring occasionally until the onions become:

  • Golden brown
  • Soft
  • Sweet and caramelized

Add:

  • Beef broth
  • Worcestershire sauce
  • Fresh thyme

Cook until the liquid reduces.

Allow the onions to cool slightly.

Step 2: Prepare The Meatloaf Mixture

In a large bowl, combine:

  • Ground beef

  • Eggs
  • Milk
  • Garlic
  • Worcestershire sauce
  • Dijon mustard
  • Salt
  • Black pepper
  • Garlic powder
  • Onion powder
  • Smoked paprika
  • Fresh herbs

Mix gently until combined.

Avoid overmixing because it can make the meatloaf dense.

Step 3: Add The Cheese Filling

Place half of the meat mixture onto a lined baking sheet.

Shape into a loaf.

Create a small trench in the center.

Add:

  • Caramelized onions
  • Gruyère cheese
  • Mozzarella cheese

Cover with the remaining meat mixture.

Seal the edges carefully to keep the cheese inside.

Step 4: Prepare The Topping

In a small bowl, combine:

Spread evenly over the top of the meatloaf.

on top.

Return to the oven until melted and bubbly.

Step 7: Rest Before Slicing
