How to Serve French Onion Soup Burgers
Serve these burgers hot, right after you assemble them. You can pair them with crispy fries, a fresh salad, or your favorite dipping sauce. For extra fun, you might want to serve them with a side of French onion soup for dipping!
How to Store French Onion Soup Burgers
If you have leftovers, store the components separately. Keep the patties and caramelized onions in airtight containers in the fridge for up to 3 days. You can reheat them in the microwave or on the stove. The buns are best when eaten fresh but can also be toasted again.
