Ingredients

Makes 2 servings

3 unsalted butter
1 olive oil
1 olive oil
1/2 red onion
1/2 yellow onion
1 salt
1/2 fresh ground black pepper
2 blue cheese
2 Dijon mustard

Method

Heat one tablespoon of the butter and one tablespoon of the oil over medium and add both types of onion and a little salt and freshly ground black pepper; cook, stirring, until crispy and brown, about 15 minutes, then set aside.
Mash together the remaining 2 tablespoons butter, the cheese and mustard and set aside.
Rub the steaks with salt and pepper; heat the remaining 1 teaspoon olive oil in a medium cast-iron skillet over high heat; when very hot, add both the steaks and cook without disturbing for 2 minutes; flip and brown the other side for 2 more minutes- this will give you medium doneness but still pink meat.
Place the steaks onto the roll bottoms, top each with half the butter mixture and then smother with onions; top with the roll tops and eat with ice cold, alcoholic beverages on a Friday evening.

Cook's notes

For the best crust, pat the steaks dry with paper towels before seasoning.
Use a cast-iron skillet for even searing and maximum flavor.
Let the cooked steaks rest for 2 minutes before slicing to retain juices.

Easy swaps

Instead of blue cheese, use gorgonzola or feta
Instead of Dijon mustard, use whole grain mustard or spicy brown mustard
Instead of unsalted butter, use salted butter (reduce added salt)
