- 2 tbsp butter
- 1 tbsp olive oil
- 1 envelope French onion soup mix
- ½ cup beef broth
- 1 cup breadcrumbs
- 2 large eggs
- 1 tbsp Worcestershire sauce
- 1 tsp garlic powder
- 1 tsp dried thyme

- 1 tbsp butter

Step-by-Step Instructions
Begin by caramelizing the onions, which is the heart of this recipe. Heat the butter and olive oil in a large skillet over medium heat. Add the onions and sauté slowly, stirring often. After about 10 minutes, sprinkle with a pinch of salt.
Continue cooking until the onions turn deep golden brown—this may take 25–30 minutes but creates the rich, sweet, savory base essential for that French onion flavor. Once caramelized, remove half of the onions to use inside the meatloaf and set the rest aside for the glaze.
Preheat your oven to 375°F (190°C). In a mixing bowl, combine the ground beef, French onion soup mix, beef broth, breadcrumbs, eggs, Worcestershire sauce, garlic powder, thyme, salt, pepper, and the reserved caramelized onions.
Mix gently using your hands or a spoon—overmixing can create a dense loaf. Fold in the shredded Gruyère or Swiss cheese so every slice gets pockets of melty goodness. Transfer the mixture to a loaf pan and shape it evenly, smoothing the top slightly.
Cover loosely with foil and bake for 40 minutes. Meanwhile, make the French onion glaze. Melt the butter in the same skillet used for the onions. Add the flour and whisk until combined. Slowly pour in the beef broth and Worcestershire, whisking until a thick gravy forms.
Stir in the remaining caramelized onions. After 40 minutes of baking, remove the foil and spoon the glaze generously over the meatloaf. Sprinkle with shredded cheese and return to the oven uncovered for another 15–20 minutes, allowing the cheese to melt and the glaze to bubble.
Remove the meatloaf from the oven and let it rest for 10 minutes before slicing. The rest time helps keep the loaf juicy and prevents crumbling. Slice thick pieces and spoon additional glaze over each serving for a rich, luxurious finish.
Pair with mashed potatoes, roasted vegetables, or buttered noodles. This meatloaf tastes even better the next day as the flavors meld, making it ideal for leftovers or meal prep.
Expert Tips for Success
Caramelizing onions properly is essential for capturing that true French onion flavor. Cook them slowly over medium heat, allowing their natural sugars to develop into deep golden sweetness. Rushing this step will leave them pale and lacking richness.
Choose ground beef with at least 80% lean content—it provides enough fat for juicy texture without making the loaf greasy. When combining the mixture, mix gently and only until combined. Overworking the meat can make your loaf firm and dense instead of tender and moist.
Adding cheese directly into the meat mixture ensures every slice has pockets of melty goodness. Gruyère is classic for French onion flavor, but Swiss or provolone can work well too.
Keep the beef broth measure accurate; too much liquid can cause the loaf to fall apart. Letting the loaf rest before slicing is a simple but crucial trick—this helps redistribute juices and prevents breakage.
Try caramelizing the onions a day ahead if you want to save time. This not only makes prep easier but also allows the flavors to deepen overnight. If you want a crispier top, skip the foil for the first half of the bake, though the loaf may brown more quickly.
And if you love bold flavor, add a splash of sherry or wine to the caramelized onions—just cook it off before combining with the meat.
Variations and Substitutions
You can easily customize this meatloaf by changing the cheese. Gruyère brings nutty richness, while mozzarella offers extra melt and cheddar gives sharper flavor. If you want a lighter version, mix half beef and half ground turkey—the caramelized onions help keep it moist and flavorful.
You can also add sautéed mushrooms to deepen the French onion vibe and add more savory complexity.
Swap the breadcrumbs for crushed crackers or panko to adjust texture. For gluten-free versions, use gluten-free breadcrumbs and broth.
If you want a spicy kick, add crushed red pepper or diced jalapeños to the mixture. For an even richer result, stir a bit of sour cream into the glaze after cooking for a creamy finish that mimics classic onion dip.
Try using French fried onions on top instead of extra cheese during the final bake. This gives a crunchy, flavorful topping. Add fresh herbs such as parsley or chives to brighten the flavor profile.
You can also stuff the center of the meatloaf with cheese for a molten surprise when slicing. With a few tweaks, this recipe adapts to almost any taste preference.
Serving Suggestions and Pairings
Serve French Onion Meatloaf with buttery mashed potatoes—they soak up the onion gravy perfectly. Roasted vegetables such as carrots, Brussels sprouts, or green beans create a lovely balance against the richness.
A simple side salad with vinaigrette helps cut through the savory flavors and keeps the meal vibrant. Warm dinner rolls or crusty bread are perfect tools for scooping up the glaze.
This dish also pairs beautifully with pasta, especially buttered egg noodles that cradle the gravy. Layer a slice onto toasted bread with melted cheese for an irresistible meatloaf melt. Leftovers are especially delicious served over rice or mashed cauliflower for a quick, satisfying bowl.
If serving for a gathering, slice the loaf ahead and spoon gravy over each piece to maintain moisture and elegance.
For beverages, try pairing with red wine like Cabernet, Merlot, or Pinot Noir—their deep flavors match the caramelized onions perfectly.
Sparkling cider or iced tea also complements the dish beautifully. For a comforting winter meal, serve with hot French onion soup as a starter. No matter how you plate it, this meatloaf brings warmth and comforting depth to any dinner table.
Storage, Freezing, and Reheating
Store leftover slices in an airtight container in the refrigerator for up to four days. The flavors deepen beautifully overnight, making each reheated slice even more satisfying. To reheat, place slices in a skillet with a splash of broth and warm gently until heated through.
This method keeps the meatloaf juicy and prevents it from drying out. The oven also works well—heat at 325°F (160°C) for 10–12 minutes.
To freeze, allow the meatloaf to cool completely. Wrap individual slices in plastic wrap, then place them in a freezer-safe bag. They keep well for up to three months. Thaw overnight in the refrigerator before reheating using your preferred method.
If freezing a whole loaf, wrap tightly and store without the glaze. Make fresh glaze when reheating for the best texture and flavor.
Air frying leftovers creates a lightly crisp exterior while keeping the inside moist. Add a spoonful of onion gravy after heating to refresh the flavors.
Always store gravy separately to prevent sogginess. This meatloaf reheats exceptionally well, making it perfect for meal prep, lunches, or fast dinners without sacrificing taste.
