Inspiration: I think Brandon could eat truffles/truffle salt/truffle oil at every meal and never tire of it. He just loves it (…and I certainly won’t turn it away, either). We bought a nice little bottle about a year ago that has lasted us a good long time, and it’s always fun experimenting and trying to come up with new uses for it. We love to cook fries or sweet potato fries in goose/duck fat, and then sprinkle them with plenty of Kosher salt and drizzle them with truffle oil. That’s our absolute favorite use of the truffle oil for sure. But it sure is great in a lot of different applications – it adds such a super flavorful and fancy flair to so many dishes.
What We Loved: There were a lot of earthy flavors in this burger that all complemented each other very well. Both rosemary and truffles have a very rich, earthy, almost primal flavor, and the smoky, nutty gruyere cheese played off of those flavors so well. There’s nothing like a really great smoked cheese to top off a burger (and this particular cheese was just fantastic – so rich, smoky, nutty, and creamy). Brandon and I both love grilled onion slices on burgers, too – something about grilling the onion lends an awesome charred flavor that is just fantastic. We used Vidalia onions here, so there was also a nice hint of sweetness to contrast with all of the other richer, deeper flavors.
Tips: Rosemary has a pretty potent flavor, so use as much or as little as you’d like, depending on how strong you want that flavor to be. The same goes for truffle oil. Truffle oil is pricey, but you really never need too much when you’re using it. Just a few drizzles will impart loads of flavor.
Rosemary Truffle Burgers
Source: Original Recipe to Serve 2
1 lb ground beef
Handful rosemary, minced
Applewood smoked gruyere cheese, shredded
2 thick slices Vidalia onion
1. Place the ground beef in a bowl. Add the rosemary, and drizzle with truffle oil. Season to taste with seasoning salt and garlic powder. Mix well with your hands, and form into two burgers.
2. Place the onion slices on the grill, and grill until they are nice and browned. Meanwhile, grill the burgers until they’re cooked through, about 4 minutes per side. A few minutes before you take the burgers off of the grill, top with the gruyere cheese.
3. Serve the burgers topped with the onion slices and drizzled generously with more truffle oil.
