How to Make French Onion Meatloaf
1️⃣ Caramelize the Onions:
Heat olive oil in a large skillet over medium heat. Add sliced onions and cook slowly, stirring often, for about 25-30 minutes until deep golden and soft. Add garlic and cook 1 minute more. Remove half the onions and set aside — these go in the meatloaf!
2️⃣ Mix the Meatloaf:
In a large bowl, combine ground beef, half the caramelized onions, Worcestershire sauce, eggs, panko breadcrumbs, thyme, Dijon mustard, salt, and pepper. Mix just until combined — don’t overwork it!
3️⃣ Shape & Bake:
Preheat oven to 375°F (190°C). Shape the meat mixture into a loaf and place in a loaf pan or on a parchment-lined baking sheet. Bake for about 40-45 minutes.
4️⃣ Make the Onion Sauce:
While the meatloaf bakes, return the reserved onions to the skillet over medium heat. Add butter and melt. Stir in flour and cook 1 minute, then slowly whisk in beef broth and milk. Simmer until thickened, about 5-7 minutes.
5️⃣ Add the Cheese:
Sprinkle shredded mozzarella and Gruyère over the meatloaf. Return to the oven for another 10-15 minutes, or until cheese is melted and golden.
6️⃣ Serve:
Let the meatloaf rest for 5-10 minutes. Slice, spoon over warm onion sauce, and dig in!
What to Serve With French Onion Meatloaf

Tips for Success
✨ Caramelize onions low and slow — don’t rush!
✨ Fresh thyme adds beautiful flavor, but dried works in a pinch.

✨ Leftover slices make the best sandwiches the next day.
How to Store & Reheat
- Fridge: Store slices in an airtight container for up to 4 days.
- Freezer: Wrap tightly and freeze for up to 3 months.
- Reheat: Warm gently in the oven at 300°F or microwave until heated through.
