Cooking method
- Caramelize the onions: In a large skillet, melt the butter over medium heat. Add the sliced onions and sugar, stirring frequently. Cook them for 20-25 minutes until they turn a deep golden color. If they start to stick, deglaze with a splash of beef broth.
- Prepare the beef patties: In a bowl, season the ground beef with salt, pepper, and Worcestershire sauce. Form into four patties.
- Cook the patties: Grill or pan-fry the patties over medium-high heat until they reach your desired doneness, about 4-5 minutes per side for medium.
- Prepare buns (optional): If you wish to make garlic butter buns, mix minced garlic with melted butter and lightly brush the buns before toasting them until golden.
- Assemble the burgers: Place a patty on each bun, top generously with caramelized onions and a slice of cheese. Broil until the cheese is melted and bubbly.
- Add the finishing touch: Sprinkle fresh thyme over the melted cheese. Close each burger with the top bun and serve immediately.
Best ways to enjoy it
French Onion Soup Burgers are best served hot and fresh, allowing the cheese to ooze out with every bite. Pair these sumptuous burgers with crispy homemade fries, onion rings, or a refreshing side salad. A glass of red wine or a cold craft beer complements the rich flavors beautifully, making for an enjoyable meal. For an elevated experience, consider adding a dab of Dijon mustard or a homemade aioli for an extra layer of flavor.
Storage and reheating tips
If you have any leftovers (though unlikely!), cool the burgers completely and store them in an airtight container in the refrigerator for up to 3 days. You can also freeze individual patties or fully assembled burgers. To reheat, simply warm them in the oven until heated through, or use a microwave for a faster option, although the oven will help retain that delicious texture.
Helpful cooking tips
- Patience is key when caramelizing onions. Don’t rush the process; let them cook low and slow for maximum sweetness.
- For extra flavor, consider adding a splash of white wine to the onions as they caramelize.
- Use lean ground beef mixed with some fats like bacon or beef tallow for extra juiciness.
- If you’re in a hurry, you can use pre-caramelized onions or sautéed onions from the store.
Creative twists
Want to mix things up? Consider trying these variations:
- Add some heat: Mix in spicy mustard or jalapeños to the patty for a fiery kick.
- Go gourmet: Swap out the traditional cheese for blue cheese or pepper jack for a different flavor profile.
- Barbecue twist: Incorporate barbecue sauce during cooking for a smoky flavor.
- Herb makeover: Experiment with different herbs like rosemary or parsley for added depth.
