Perfect Smash Burger
June 22, 2026
As with all smash burgers, achieving smash success relies heavily upon using the right burger press. A non-ridged press allows you to apply even pressure and create those trademark thin and crispy patties without a lot of grease buildup. The result is a crispy, cooked-through burger that holds its own among all your favorite toppings.
This recipe also highlights a super easy, exceptionally tangy burger sauce made with five simple pantry ingredients. This creamy, delicious sauce will soon become a family go-to topping for burger night.
This is a harmonious, can’t-put-it-down burger that just might make you do that dance, the one you do when something tastes really, really good. Absolutely a restaurant-quality meal you can make at home… which is good in case you don’t want anyone to see that dance (we don’t judge).
