How to Make French Onion Meatloaf
Step 1: Caramelize the Onions
Melt the butter in a large skillet over medium-low heat. Add the sliced onions, salt, and sugar.
Cook the onions for 20 to 25 minutes, stirring occasionally, until they are soft and golden brown. Lower the heat if they begin to brown too quickly.
Add the garlic and thyme. Cook for another minute. Pour in the beef broth and scrape up any browned bits from the bottom of the skillet. Continue cooking until most of the liquid has evaporated.
Remove the skillet from the heat. Set aside half of the onions for the meatloaf and leave the remaining onions in the skillet for the gravy.
Step 2: Prepare the Meatloaf Mixture
Preheat the oven to 375°F. Lightly grease a 9-by-5-inch loaf pan or line a rimmed baking sheet with parchment paper.
In a large mixing bowl, combine the ground beef, breadcrumbs, French onion soup mix, eggs, milk, Worcestershire sauce, ketchup, garlic powder, black pepper, ½ cup shredded cheese, and half of the caramelized onions.
Gently mix everything together until just combined. Avoid overmixing because that can make the meatloaf dense or tough.
Step 3: Shape and Bake
Transfer the meat mixture to the prepared baking sheet and shape it into an even loaf. You can also press it gently into the prepared loaf pan.
Bake for 45 minutes.
Remove the meatloaf from the oven and sprinkle the remaining ½ cup of cheese over the top. Return it to the oven and bake for another 15 to 20 minutes, or until the cheese is melted and the center of the meatloaf reaches 160°F.
Let the meatloaf rest for at least 10 minutes before slicing.
Step 4: Make the French Onion Gravy
While the meatloaf rests, add 2 tablespoons of butter to the skillet containing the remaining caramelized onions.
Once the butter melts, sprinkle the flour over the onions. Cook for one minute while stirring constantly.
Slowly pour in the beef broth, whisking as you pour. Add the Worcestershire sauce and bring the gravy to a gentle simmer.
Cook for 5 to 7 minutes, stirring frequently, until the gravy thickens. Taste and season with salt and black pepper as needed.
Step 5: Serve
Slice the rested meatloaf and spoon the warm French onion gravy over each serving. Add a little extra shredded cheese or fresh thyme on top, if desired.
Tips for the Best French Onion Meatloaf
Don’t rush the onions
Caramelized onions need time to become soft, sweet, and deeply golden. Keep the heat around medium-low and stir them occasionally so they cook evenly without burning.
Use ground beef with some fat
An 85/15 ground beef blend works well for meatloaf. Very lean ground beef can produce a dry loaf, while fattier beef may make it greasy.
Mix the meat gently
Use clean hands or a fork to combine the ingredients just until everything is incorporated. Overmixing compresses the meat and can create a tough texture.
Check the temperature
The easiest way to know when meatloaf is finished is to use an instant-read thermometer. The center should reach 160°F.
Let it rest before slicing
Resting gives the juices time to redistribute and helps the loaf hold its shape. If you slice it immediately, it may crumble or lose moisture.
What Cheese Is Best for French Onion Meatloaf?
Gruyère is the classic cheese used in French onion soup, so it gives this meatloaf the most traditional flavor. It melts beautifully and has a rich, slightly nutty taste.
Swiss cheese, provolone, or mozzarella can also be used. Swiss is the best affordable substitute if Gruyère is unavailable.
What to Serve With French Onion Meatloaf
French onion meatloaf pairs especially well with creamy potatoes or noodles that can soak up the savory gravy. Try serving it with:
Make It Your Own
- Stuff the meatloaf with an additional layer of Gruyère or Swiss cheese.
- Use a mixture of ground beef and ground pork for extra flavor.
- Add sautéed mushrooms to the onions and gravy.
- Replace the breadcrumbs with crushed buttery crackers.
- Add fresh thyme or chopped parsley to the meat mixture.
- Use provolone or mozzarella for a milder cheese flavor.
- Make individual mini meatloaves and reduce the baking time.
Can I Make French Onion Meatloaf Ahead of Time?
Yes. Prepare and shape the meatloaf up to one day in advance. Cover it tightly and keep it refrigerated until you are ready to bake it.
Let the cold meatloaf sit at room temperature while the oven preheats. It may need an additional 5 to 10 minutes in the oven.
The onions can also be caramelized up to three days ahead and stored in an airtight container in the refrigerator.

Notes
Use 85% lean ground beef for a moist, tender meatloaf. Extra-lean ground beef can make the finished meatloaf dry.
Cook the onions slowly over medium-low heat so they caramelize without burning.
Mix the meatloaf ingredients only until combined. Overmixing can create a dense or tough texture.
Gruyère gives the recipe the most traditional French onion flavor. Swiss or provolone can be substituted.
Allow the meatloaf to rest for at least 10 minutes before slicing so it holds together.
Store leftover meatloaf and gravy separately in airtight containers in the refrigerator for up to four days.
How to Store Leftover Meatloaf
Store leftover French onion meatloaf and gravy in separate airtight containers in the refrigerator for up to four days.
Reheat individual slices in the microwave or place them in a covered baking dish with a spoonful of gravy. Warm in a 325°F oven until heated through.
Can You Freeze French Onion Meatloaf?
French onion meatloaf freezes well. Allow the cooked meatloaf to cool completely, then wrap the whole loaf or individual slices tightly in plastic wrap and aluminum foil.
Freeze it for up to three months. Thaw overnight in the refrigerator before reheating.
The gravy can also be frozen, but it may separate slightly after thawing. Whisk it over low heat while reheating to bring it back together.
Frequently Asked Questions
Can I use a loaf pan?
Yes. A 9-by-5-inch loaf pan will work. However, shaping the meatloaf on a rimmed baking sheet allows more of the outside to brown and prevents it from sitting in excess grease.
Can I use onion soup from a can?
A can of condensed French onion soup can be used, but you will need to reduce the milk so the meat mixture does not become too wet. For the most consistent results, this recipe uses dry onion soup mix and homemade caramelized onions.
Why is my meatloaf falling apart?
Meatloaf can fall apart if it does not contain enough binder, is sliced before resting, or contains too much liquid. Measure the milk carefully and let the cooked meatloaf rest for at least 10 minutes.
Can I make it without cheese?
Yes. The cheese adds the familiar flavor of French onion soup, but the meatloaf will still be flavorful without it. Simply leave it out and serve the meatloaf with plenty of onion gravy.
How do I keep meatloaf from drying out?
Use ground beef with some fat, avoid overmixing, and remove the meatloaf from the oven as soon as it reaches 160°F. The milk, eggs, onions, and breadcrumbs also help keep the inside moist.
Final Thoughts
This French onion meatloaf is the kind of comforting dinner that makes an ordinary weeknight feel a little more special. The tender beef, sweet caramelized onions, melted cheese, and savory gravy bring together everything you love about French onion soup in a hearty main dish.
Serve it over mashed potatoes with plenty of onion gravy for a cozy, satisfying meal that is just as good reheated the next day.
