I first made this French Onion Meatloaf on a chilly weeknight when I wanted a single-dish dinner that felt indulgent but was simple to pull off. It’s a savory meatloaf built around caramelized onions and French onion soup, finished with melted Swiss for that classic French onion flavor in every bite. It’s hearty enough for family dinner, yet elegant enough to serve when friends drop by.
Why you’ll love this dish
This meatloaf hits comfort-food notes—rich, caramelized onions, umami from Worcestershire and Parmesan, and gooey Swiss on top—without complicated steps. It’s budget-friendly, feeds a crowd, and uses pantry staples with one standout twist: French onion soup adds both moisture and concentrated onion flavor so you don’t need to drown the loaf in sauce later. Make it for weeknights, casual dinner parties, or a cozy Sunday supper.

How this recipe comes together
Short overview so you know what to expect:
- Caramelize onions until richly browned. This builds the French onion flavor.
- Mix the onions with ground beef, breadcrumbs, eggs, Parmesan, seasonings, and a cup of French onion soup for moisture and depth.
- Shape into a loaf and bake until nearly done.
- Top with shredded Swiss and return to the oven until the cheese melts.
- Rest, slice, and serve.
This sequence keeps the meatloaf moist and flavorful while avoiding overworking the meat—key for a tender bite.
What you’ll need
- 2 pounds ground beef (see note below)
- 1 cup onion, finely chopped (about 1 large onion)
- 1 cup breadcrumbs
- 2 large eggs
- 1/2 cup grated Parmesan cheese
- 1 cup French onion soup (canned or homemade)
- 1 tablespoon Worcestershire sauce
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1 cup shredded Swiss cheese
- Fresh parsley, for garnish (optional)
Ingredient notes and substitutions:
- Ground beef: 80/20 (fat/lean) gives good juiciness. For leaner meatloaf, use 85/15 and add a tablespoon of olive oil or a splash more soup.
- French onion soup: canned works fine; use homemade for a fresher flavor. If you don’t have soup, deglaze the skillet with 1/2 cup beef broth plus 1/2 cup caramelized onion plus a teaspoon of soy sauce.
- Breadcrumbs: panko adds a lighter texture; regular breadcrumbs make the loaf denser.
- Parmesan & Swiss: Parmesan gives umami inside the loaf; Swiss on top provides that classic French onion melt. Gruyère can substitute for Swiss.

Step-by-step instructions
- Preheat the oven to 350°F (175°C). Lightly grease a 9×5-inch loaf pan or line it with parchment.
- Heat 1–2 tablespoons oil in a skillet over medium heat. Add the chopped onions and a pinch of salt.
- Sauté the onions, stirring occasionally, until deep golden brown and caramelized—about 8–12 minutes. Lower heat if they begin to burn.
- Transfer the onions to a large mixing bowl. Let them cool slightly so they don’t cook the beef when combined.
- Add the ground beef, breadcrumbs, eggs, Parmesan, French onion soup, Worcestershire, garlic powder, onion powder, salt, and pepper to the bowl.
- Gently mix with your hands or a sturdy spoon until ingredients are just combined. Stop as soon as the mixture is uniform—overmixing makes meatloaf dense.
- Shape the mixture into a loaf and place it in the prepared pan. Smooth the top so cheese will melt evenly.
- Bake uncovered for 45 minutes.
- Remove the meatloaf and evenly sprinkle the shredded Swiss cheese over the top.
- Return to the oven and bake another 10–15 minutes, until the cheese is melted and the internal temperature of the meatloaf reaches 160°F (71°C) with an instant-read thermometer.
- Let the meatloaf rest for 10 minutes before slicing. This allows juices to redistribute and makes cleaner slices.
- Garnish with chopped parsley if desired and serve warm.
Best ways to enjoy it
- Classic pairing: mashed potatoes or buttery egg noodles to soak up juices.
- Bright sides: a crisp green salad or roasted Brussels sprouts cuts the richness.
- Bread: thick-sliced sourdough or a warm baguette for sopping melted cheese.
- For a dinner party, slice the meatloaf and plate with roasted root vegetables and a sprig of thyme for presentation.
Storage and reheating tips
- Refrigerator: Cool to room temperature, then store in an airtight container within 2 hours of cooking. Keeps 3–4 days.
- Freezing: Wrap whole or in slices tightly in plastic wrap and aluminum foil or freeze in an airtight container for up to 3 months. Thaw overnight in the refrigerator before reheating.
- Reheating: Reheat slices in a 350°F (175°C) oven for 10–15 minutes, or microwave on medium power in 30-second bursts until warmed through. To preserve moisture, add a splash of beef broth to the baking dish and cover with foil.
- Food safety: Ground beef should reach an internal temperature of 160°F (71°C). Refrigerate leftovers promptly to minimize bacterial growth.

Pro chef tips
- Don’t skip caramelizing the onions. Those browned bits are where the signature flavor comes from.
- Use a light hand when mixing. Overworked meat traps air and becomes tough.
- If your meatloaf sinks in the middle, try forming a shallow indentation along the top before baking; this helps even cooking.
- For crisper edges, bake on a rimmed sheet pan instead of a loaf pan. The pan concentrates heat and crisps the outside.
- Test doneness with an instant-read thermometer rather than slicing early; you’ll retain juices and get an accurate result.
Creative twists
- Turkey or chicken version: swap ground turkey and increase moisture with an extra egg or 1/4 cup sour cream. For a tested turkey option, compare techniques in this resource: https://www.inspiredtaste.net/21535/unbelievably-moist-turkey-meatloaf-recipe/
- Vegetarian take: make a lentil-and-mushroom loaf, using caramelized onions and a cup of vegetable broth to mimic the soup flavor.
- BBQ finish: substitute Swiss with sharp cheddar and brush the top with your favorite barbecue glaze for smoky-sweet notes.
- Gluten-free: use gluten-free breadcrumbs or crushed gluten-free crackers.
- Extra onion punch: fold in a little caramelized onion jam or a tablespoon of balsamic reduction for a sweet-savory boost.
Common questions
Q: How long does this take from start to finish?
A: Plan about 15 minutes active prep, 10–12 minutes to caramelize onions, 45–60 minutes total baking including cheese finish, plus 10 minutes resting. Total time ~1 hour 25 minutes.
Q: Can I make this ahead and bake later?
A: Yes. Assemble the loaf, cover tightly, and refrigerate up to 24 hours before baking. If chilled, add 5–10 minutes to the baking time.
Q: What internal temperature should the meatloaf reach?
A: For ground beef, the safe internal temperature is 160°F (71°C). Use an instant-read thermometer in the center to confirm.
Q: My meatloaf was dry—how can I keep it moist?
A: Use 80/20 beef and don’t overmix. The cup of French onion soup adds moisture; if using lean meat, increase moisture slightly (extra soup or an egg).
Q: Can I use caramelized onions from a jar or buy pre-made soup?
A: Yes. Pre-made caramelized onions and canned French onion soup are convenient and perfectly acceptable—just taste and adjust salt as needed.
