A juicy, savory meatloaf loaded with caramelized onions, melty cheese, and rich French-onion flavor. Perfect for a comforting family dinner.
Ingredients
For the meatloaf:
2 lb (900 g) ground beef, preferably 80–90% lean
2 large yellow onions, thinly sliced
2 tbsp butter
1 tbsp olive oil
3 cloves garlic, minced
1 cup breadcrumbs
2 large eggs
½ cup milk
1 tbsp Worcestershire sauce
1 tsp Dijon mustard
1 tsp dried thyme
1 tsp salt
½ tsp black pepper
½ tsp onion powder
1 cup shredded Gruyère or Swiss cheese
For the topping:
1 cup shredded Gruyère, Swiss, or mozzarella cheese
½ cup caramelized onions
1–2 tbsp fresh parsley, chopped
Optional onion gravy:
1 cup beef broth
1 tsp Worcestershire sauce
1 tsp cornstarch
1 tbsp water
½ tsp dried thyme
Instructions
1. Caramelize the onions
Heat butter and olive oil in a large skillet over medium-low heat. Add the sliced onions and cook for 25–35 minutes, stirring occasionally, until deeply golden, soft, and caramelized.
Add the garlic during the final 1–2 minutes. Remove from the heat and let the onions cool slightly.
2. Prepare the meat mixture
Preheat the oven to 375°F (190°C).
In a large bowl, combine breadcrumbs and milk. Let stand for about 2 minutes.
Add the ground beef, eggs, Worcestershire sauce, Dijon mustard, thyme, salt, pepper, and onion powder.
Add about ½–¾ cup of the caramelized onions and 1 cup shredded cheese.
Mix gently with your hands until just combined. Avoid overmixing, which can make the meatloaf dense.
3. Shape the meatloaf
Line a baking sheet or loaf pan with parchment paper.
Shape the mixture into a loaf approximately 9 × 5 inches. Place it on the prepared pan.
4. Bake
Bake for approximately 45–55 minutes, or until the center reaches 160°F (71°C) on a meat thermometer.
Remove from the oven and carefully drain excess grease if necessary.
5. Add the French onion topping
Spread the remaining caramelized onions over the meatloaf.
Cover generously with shredded Gruyère or Swiss cheese.
Return to the oven for 5–8 minutes, or until the cheese is completely melted and bubbling.
For a more golden top, broil for 1–2 minutes, watching carefully.
6. Rest and serve
Let the meatloaf rest for 10–15 minutes before slicing. Sprinkle with fresh parsley and serve warm.
Optional Onion Gravy
Add beef broth, Worcestershire sauce, and thyme to the onion skillet.
Bring to a gentle simmer.
Mix cornstarch with water until smooth.
Stir it into the simmering broth.
Cook for 2–3 minutes until slightly thickened.
Spoon the gravy over the sliced meatloaf.

Recipe Q&A
Q: Can I make French Onion Meatloaf ahead of time?
Yes. Assemble the meatloaf, cover it tightly, and refrigerate for up to 24 hours before baking.
Q: Can I freeze it?
Yes. You can freeze the cooked meatloaf for up to about 3 months. Cool completely, wrap tightly, and thaw overnight in the refrigerator before reheating.
Q: Why is my meatloaf falling apart?
It may not have enough binder, or it may have been sliced immediately after baking. Make sure you use the eggs and breadcrumbs and allow the meatloaf to rest for 10–15 minutes.
Q: Can I use mozzarella instead of Gruyère?
Absolutely. Gruyère gives the most classic French-onion flavor, but Swiss, provolone, or mozzarella work well.
Q: How do I know when it’s done?
The safest method is to check the center with an instant-read thermometer. Ground beef meatloaf should reach 160°F (71°C).
Q: Can I make this with ground turkey?
Yes. Ground turkey can be substituted, although the meatloaf will be leaner and slightly less rich.
Q: How can I make it lower-carb?
Replace regular breadcrumbs with crushed pork rinds or a low-carb breadcrumb alternative, and use a low-carb milk substitute.
Q: How do I get deeply caramelized onions?
Cook them slowly over medium-low heat and don’t rush the process. They need around 25–35 minutes to develop that rich, sweet flavor.
