PREPARATION METHOD
To make onions 
1. In a medium cast iron pan over medium-high heat, melt butter 
and oil. Add onions and a pinch of salt; stir to coat. 2. Reduce heat 
to low and cook, stirring every few minutes, until the onions are 
softened and golden brown, at least 20 minutes. 3. Remove from 
heat, add whiskey, stir to coat, and return to the rangetop. Over 
medium heat, cook just until the alcohol smell is cooked o; set aside. 
To make mushrooms 
1. In a medium cast iron pan over medium-high heat, melt butter 
and oil. When oil shimmers, add mushrooms, thyme, and garlic; stir 
to coat in oil, season with salt and pepper, and cook undisturbed at 
least 5 minutes. 2. Stirring occasionally, cook until the mushrooms 
have released excess water and turn golden brown, about 5 to 10 
minutes more. Remove from heat and set aside. 
To make burgers 
1. Heat griddle to 375°F. In a large bowl, mix bison and salt until well 
combined. 2. Shape into eight ¼-inch patties; brush with vegetable 
oil. 3. Cook patties until browned on first side, about 1–2 minutes. 
Flip and cook to desired doneness, about 1–2 minutes more. 
3. Serve sliders on buns topped with mayonnaise, mushrooms, 
onions, and arugula.
