Getting better at smash #burgers and the #Oklahoma style onion burger method is so good with the onions grilled into the burger. I'm honestly surprised it's not more popular nationwide. I like the original style but did these with a #ShakeShack or #InNout type sauce, pickles and tomato.#Burger#SmashBurger#HomeCook #SeriousEats#OnionBurger#Food#FoodPorn
