Nothing beats a burger hot off the grill! This one is topped with caramelized onions and melted Gruyère for an extra pop of flavor!!
While I try to eat healthy as often as possible a juicy burger has got to be one of my favorite indulgences! I just love a nice juicy burger topped with gooey melted cheese! When I'm eating out I'm a big fan of the classic cheeseburger, however, when I make burgers at home I like to switch it up a little bit.
When you're cooking at home it's a great opportunity to try different flavor combinations. This Gruyère & Caramelized Onion Burger is one of my favorites! It has some classic flavors - it's a bit like french onion soup meets burger.
Personally, I think the best way to cook a burger is on the grill. Grilled burgers just seem to taste better, don't you agree?? It's something about that slightly char-grilled taste that is amazing. And while a grilled burger is certainly a summertime classic, I actually fire up my grill all year around to make them - unless it's sub-zero outside that is.
The key to a great burger is using high-quality ground beef - I prefer 93% lean. Then you'll add some tasty seasonings into the meat and top it with cheese and other yummy things - in this case those other yummy things would be the caramelized onion burger topping.
Caramelized onions make a great burger topping - the provide excellent flavor and because they are cooked they stay on the burger better than raw onions. For this burger, I like brioche buns as they are a bit lighter than a traditional hamburger bun and also toast nicely. If you prefer you can always use a regular hamburger bun or whole-grain roll.
How to grill burgers on a gas grill
Make the patties: When grilling burgers you want to start by making evenly sized patties that are about ¾ of an inch thick. Using your thumb, make a depression in the center of each patty. I used a pound of ground beef for this recipe, so depending on who you are feeding that will make 3-4 burgers.
Preheat and clean the grill: Next, you want to pre-heat the grill to 400°F. If your grill grates are well seasoned you don't need to oil them before adding the burgers. If you are worried about the burgers sticking take a paper towel and dip it in a bit of olive or avocado oil. Use your barbeque tongs to brush the grill with oil.
Cook the burgers: Allow the burgers to cook for 3-5 minutes on the first size. As tempting as it is, don't press down on them with your grill spatula. You don't want to squeeze all the juices out of the burger! After you flip the burgers you'll cook them for an additional 3-4 minutes until they reach the desired doneness. You can use a timer as a guide however be sure to check the temperature with an instant-read thermometer, which should read at least 160°F. Like ovens, grill temperatures vary so cooking time on your grill may be slightly different.
Let the burgers rest: Once they reach the desired temperature, the burgers need to rest for a few minutes. Then add the rest of your toppings and enjoy!

Grand Cru Cheese Slices – This is an American made cheese that is very similar to Gruyère and works well on burgers, so if you can't find a good Gruyère or don't want to bother with slicing it very thinly, this is a great alternative.
Instant Read Thermometer - I love using this fork style thermometer when I'm grilling. It's easy to read the temperature and the handle is long enough that you won't accidentally burn yourself on the hot grill.
