How to Make French Onion Meatloaf

Preheat your oven to 375°F (190°C). This will ensure a perfectly cooked meatloaf with a lovely golden crust.
Caramelize the onions in a pan over low heat until they turn golden brown, about 20-25 minutes. This slow cooking releases their natural sweetness, which is key to the dish’s flavor.
Combine ground beef, caramelized onions, eggs, breadcrumbs, and milk or broth in a large bowl. Mix until just combined to keep the meatloaf tender—avoid overmixing!
Shape the mixture into a loaf and place it in a greased baking dish. Make sure it’s well-formed to allow even cooking.
Bake in the preheated oven for 50-60 minutes, or until the internal temperature reaches 160°F (71°C). The meatloaf should be firm, yet moist.
Rest for 10 minutes before slicing to allow the juices to redistribute, ensuring every slice is moist and flavorful.

Optional: Garnish with fresh parsley for a pop of color.
