I’m using Roth gouda, which is made in Wisconsin and melts like a dang dream. This ooey gooey cheese compliments the sweet caramelized onions, the fragrant garlicky truffle mayo, and the umami-packed smash burger patty perfectly
2tablespoonGarlic truffle mayoleave the rest for dipping
4ozGouda Cheesegrated (a little over half a wedge)
1cooked Burger patty
2tablespoonCaramelized onions
Instructions
Caramelized onions
Add butter and olive oil to a medium sized pan over medium heat. Once melted, add onions and 2 pinches of kosher salt. Cook for 30-40 minutes, stirring often, until onions are soft, tender, sweet and golden.
**If you find they are starting to stick or burn to the pan, add 2 tablespoon of water as needed to deglaze.**
Truffle garlic mayo
While the onions are cooking, mix together mayo, garlic paste, truffle oil and salt and set aside.
Smash burger
Roll beef into a ball and season all sides with salt and pepper.
Heat a medium sized cast iron skillet over high heat and once it starts to smoke, carefully add oil and the burger ball right on top.
Let the burger sear on one side until dark golden brown. Then carefully flip the ball over and use the back side of a spatula to smash it as flat as possible. Let cook for 2 more minutes or until the downward facing side is dark golden brown. Flip once more to brown the remainder of the other side.
Remove from heat and set aside.
Grilled Cheese
Smear both slices of bread equally with the truffle garlic mayo.
Place half of the shredded Roth gouda on top of one of the slices.
Then add the burger patty, caramelized onions, and the rest of the cheese on top.
Place the other piece of bread (mayo side down) on top.
Add half the butter to a fry pan over medium heat. Once melted, add the sandwich on top and more around to absorb the melted butter. Smear the remaining butter on the top part of the sandwich.
Cook the sandwich for a few minutes on each side, until the bread is crispy and golden brown and the cheese has completely melted.
Remove from heat and place on a cutting board. Slice in half before serving with the remaining garlic truffle mayo. .
