What You’ll Need
- 2 lbs ground beef (80/20 lean to fat ratio)
- 3 large yellow onions, thinly sliced
- 4 tbsp unsalted butter
- 1/2 cup panko breadcrumbs
- 1 large egg, lightly beaten
- 1/4 cup beef consommé
- 1 tbsp Worcestershire sauce
- 2 tsp fresh thyme leaves
- 8 oz Gruyère cheese, shredded
- 6 thick slices sourdough bread
- 1.5 tsp kosher salt
- 1 tsp cracked black pepper
Step-By-Step Directions
- In a large skillet, melt butter over medium-low heat. Add onions and cook for 40 minutes, stirring occasionally, until deep mahogany brown and caramelized.
- Preheat convection oven to 350°F (175°C).
- In a large mixing bowl, combine the ground beef, breadcrumbs, egg, beef consommé, Worcestershire sauce, thyme, salt, pepper, and one-third of the caramelized onions.
- Shape the mixture into a rectangular loaf and place on a wire rack set over a rimmed baking sheet.
- Bake for 50 to 60 minutes, or until the internal temperature reaches 160°F (71°C).
- Allow the meatloaf to rest for 10 minutes before slicing into 1-inch thick portions.
- Arrange sourdough slices on a baking sheet. Place one meatloaf slice on each piece of bread.
- Top the meatloaf slices with the remaining caramelized onions and the shredded Gruyère cheese.
- Place under a broiler for 2 to 3 minutes until the cheese is melted, bubbly, and gold-brown.
How To Serve It
Serve these melts while the cheese is still bubbly and hot. They look amazing on a wooden serving board for guests. Pair them with a simple green side salad for balance. A cup of extra beef broth is great for dipping. This is ideal for casual hosting or cozy Sunday nights.
Leftovers & Storage
Store leftover meatloaf in the fridge for up to three days. Keep the bread separate until you are ready to eat. Reheat the meat slices in a skillet or air fryer. This keeps the edges nice and crispy for your melt. You can even freeze the cooked meatloaf for later use. Just thaw it overnight in the refrigerator before reheating.
Make It Even Better (Pro Tips)
- Don’t rush the onions because color equals deep flavor.
- Use 80/20 beef for the juiciest results every time.
- Always let the meat rest before you start slicing it.
- Try Swiss cheese if you cannot find Gruyère nearby.
- Slice the sourdough thick to support the heavy meatloaf.
- Keep a close eye on the broiler to avoid burning.
- Add a pinch of sugar to speed up onion caramelization.
Easy Ways To Change It Up
- Swap ground beef for ground turkey for a lighter meal.
- Add a splash of dry sherry to the onions for depth.
- Use gluten-free bread and breadcrumbs for sensitive guests.
- Make individual mini meatloaves to save time during baking.
Quick Questions
Can I make the onions ahead of time?
Yes, you can cook them two days early. Just keep them in a sealed container in the fridge. This makes weeknight assembly much faster for you.
What if I don’t have a wire rack?
You can bake it directly on a parchment-lined sheet. The rack just helps the heat circulate better for even cooking. Your French Onion Meatloaf Melt will still taste great.
I hope you love this cozy mashup as much as I do. It is the perfect way to warm up your kitchen. Give it a try tonight!
