Top Tips for Perfecting Your Onion Soup Burgers
Want to take your Onion Soup Burgers to the next level? Here are a few tips and tricks I’ve learned over the years:
- Patience is key with the onions: Don’t rush the caramelization process. Low and slow is the name of the game. You want those onions to be deeply golden brown and sweet, not burnt.
- Don’t overmix the burger meat: Overmixing can make the burgers tough. Gently combine the ingredients until just combined.
- Use a meat thermometer: A meat thermometer is your best friend when it comes to cooking burgers to the perfect doneness. 160°F (71°C) is the sweet spot for medium.
- Toast the buns: Toasting the buns adds a nice texture and prevents them from getting soggy.
- Don’t be afraid to experiment with cheese: Gruyere is classic, but you can also use Swiss, provolone, or even fontina.
- Add a little kick: A pinch of red pepper flakes to the caramelized onions adds a nice little kick.
One thing I’ve learned is that a little bit of balsamic glaze drizzled over the top after everything is assembled is out of this world! These are truly special burgers and I hope you enjoy experimenting with the recipe to find your favorite variation!
Storing and Reheating Tips
If you happen to have any leftover Onion Soup Burgers (which is rare in my house!), here’s how to store and reheat them:
- Refrigerator Storage: Store the burgers in an airtight container in the refrigerator for up to 3 days.
- Freezer Instructions: Wrap the burgers individually in plastic wrap and then place them in a freezer bag. Freeze for up to 2 months.
- Reheating: Reheat the burgers in a skillet over medium heat or in the microwave. If frozen, thaw them in the refrigerator overnight before reheating.
- Glaze Timing Advice: I recommend adding a touch more glaze if it’s been a few days, it helps bring the freshness back to the flavor.
To be honest, I rarely have leftovers because these burgers are so popular. But if I do, I usually just chop them up and add them to a salad or use them as a topping for nachos. Waste not, want not!
