  • 2 tablespoons Worcestershire sauce
  • 1 –2 teaspoons fresh thyme or ½ teaspoon dried
  • Salt and black pepper to taste
Optional
  • 1 cup shredded Gruyère Swiss, or mozzarella cheese
  • 2 tablespoons butter for caramelizing onions

Equipment

  • Large mixing bowl
  • Skillet or frying pan
  • Wooden spoon or spatula
  • Measuring cups and spoons

Method
 

Caramelize the onions
  1. Heat butter in a skillet over medium heat. Add sliced onions and cook slowly for 20–25 minutes until golden brown and soft. Set aside.
Prepare the meat mixture
  1. In a large bowl, combine ground beef, breadcrumbs, eggs, milk, garlic, Worcestershire sauce, thyme, salt, and pepper. Mix gently until just combined.
Add onions
  1. Fold half of the caramelized onions into the meat mixture. Reserve the rest for topping.
Shape the meatloaf
  1. Form the mixture into a loaf shape, ensuring it is firm but not overly compact.
Prepare the crockpot
  1. Lightly grease or line the crockpot. Place the meatloaf inside.
Add broth and topping
  1. Pour beef broth around the meatloaf. Spread remaining onions over the top.
Cook
  1. Cover and cook on low for 6–7 hours or high for 3–4 hours, until internal temperature reaches 160°F (71°C).
Add cheese (optional)
  1. In the last 20 minutes, sprinkle cheese on top and allow it to melt.
Rest and serve
  1. Let the meatloaf rest for 10 minutes before slicing and serving.

Notes

Caramelizing the onions is essential for authentic French onion flavor—do not skip this step.
Avoid overmixing the meat to keep the texture tender.
For a lighter version, substitute ground turkey or chicken, but add extra moisture.
Letting the meatloaf rest before slicing helps retain juices and improves texture.
You can prepare the mixture ahead and refrigerate for up to 24 hours before cooking.
