Onion Burger with Gruyère Fondue Sauce is a kicked up gourmet burger for your Holiday cookout. Hamburgers fresh off the grill with that charcoal taste, potato salad, deviled eggs, baked beans, and watermelon. Those memories are etched in our minds and just mentioning the Holiday has an impact on our senses – especially taste and smell. Times may change, but the palate wants what the palate wants! For your next holiday cookout we suggest our Onion Burger with a Gruyère Fondue Sauce!
A burger made with onions is a classic and cheese is the usual topping. However, everyone today seems to have felt the Rachel Ray “effect.” The self-proclaimed “Queen of the Burger” has certainly made more variations than one can count. So why should we be any different? Let’s take the classic burger and cheese and add some flair – low carb, of course.
We keep our burger simple. An 80-20 blend is our choice – the fat adds so much flavor and moisture. No one likes a dry burger. To the basic ground beef mix we add chopped onion, some garlic, and Worcestershire. In the past, we often made a burger using our basic meatloaf recipe. Lately, we just want that great grilled flavor of a simple burger and add the toppings to create a unique recipe.
The Gruyère cheese came to mind this year. Many will use a classic American cheese, or swiss, or even provolone to top a burger. Gruyère melts well and has a unique taste. You will find it in a quiche or fondue and in melted cheese sandwiches and cordon bleu recipes. It is more frequently used in French onion soup. Our fondue sauce works well with a burger. It is creamy, nutty, and with a bit of wine will add a new memory for the 4th.
The finishing touch on our holiday burger will continue the French theme with deeply caramelized onions. We make our onions with thyme and Worcestershire and a good bit of butter. A great topping for any burger, and especially good for our Onion Burger with Gruyère Fondue Sauce. The onions need to cook low and slow.
What would a burger be without a tasty bun? For many months we have been eating bun-less burgers or in a lettuce holder. For this holiday we went all out and used a large muffin pan and our low-carb bread recipe to make a Tasty Low Carb hamburg bun. Since posting this recipe, Joanie has also been using our own home-made yeast burger buns for these burgers.
Start with the caramelized onions first since they will take some time to turn a deep caramel color and soften. The secret is to cut your onions thin (a sweet onion is best) and brown them slowly in butter on low heat. We like a little thyme and the Worcestershire near the end of the process adds both color and flavor. Be patient – you will be rewarded with a great topping.
The key to the Guyère fondue sauce is the white wine. A dry wine works best. Try a Riesling or Chardonnay for a stronger flavor with the mellow cheese. The fondue sauce should pour easily over the burger without being too runny. If you remember the fondue years you will enjoy the taste of the beef topped with a fondue sauce.
Assemble your Onion Burger with Gruyère Fondue Sauce in the usual way. A little dab of the sauce on the bottom of the bun, lettuce, then the burger. More fondue sauce on top of the burger and then capped with the caramelized onions liberally placed before topping with your low-carb bun.
