Step-by-step instructions
- Heat the butter in a skillet over medium heat until melted. Add your sliced onions, stirring occasionally, and let them caramelize for about 15-20 minutes. They should become golden brown and sweet.
- While the onions are cooking, place the ground beef in a bowl. Season with salt and pepper, then form into burger patties of your preferred size.
- Grill or pan-fry the patties until they reach your desired level of doneness, around 4-6 minutes per side for medium.
- Once the patties are nearly done, top each one with a generous heap of caramelized onions and a slice of Swiss cheese, allowing it to melt slightly.
- Assemble the burgers on hamburger buns, and you’re ready to serve!
Best ways to enjoy it
Serve your French Onion Soup Burgers with a side of crispy French fries or a refreshing salad to balance the richness. You could also add a little Dijon mustard or a drizzle of balsamic glaze for an extra kick. For an authentic touch, consider pairing them with a simple onion soup on the side. It makes for a fun, yes-dish-plus-side combo that pays tribute to the original recipe.
Storage and reheating tips
To ensure freshness, store leftovers in an airtight container in the refrigerator for up to 3 days. When reheating, consider using the stove or oven to revive the burger patty, which will keep it juicy. If you need to freeze, wrap each burger tightly in plastic wrap, then foil. They will stay good in the freezer for up to 3 months.
Helpful cooking tips
- Patience is key when caramelizing onions; don’t rush the process, as that’s where the deep flavor comes from.
- If your patties are falling apart, try adding an egg or breadcrumbs to bind them better.
- Always let cooked meats rest for a few minutes before serving, as it allows the juices to redistribute.
Creative twists
Feel free to get adventurous! Swap out traditional Swiss for other cheeses like blue cheese for a bold flavor or Gouda for a smoky touch. You could also try adding sautéed mushrooms for an earthy depth, or even caramelized apples to introduce a sweet contrast. For a lighter version, use turkey or plant-based patties.
