Allow your steaks to come to room temperature for about 30 minutes before grilling
Pat your steak dry with paper towels and season generously with sea salt, black pepper and seasoned salt on all sides
Place a large cast iron skillet over medium to medium high heat and allow it to preheat for a few minutes
Add 2 tablespoons of butter and a splash of olive oil into the skillet and place the seasoned steaks into the warm skillet
Cook for 5-6 minutes on the first side undisturbed and then flip the steak and cook to your desired level of doneness (130 degrees for medium rare)
Once your steaks are cooked to your liking, transfer onto a cutting board and lightly cover with foil (optional)
Add the remaining 2 tablespoons of butter into the skillet along with 15 ounce can of cannellini beans with the liquid, 8 ounces of sliced mushrooms, the rosemary, thyme, red pepper flakes, finely minced garlic and shallot
Simmer for about 5 minutes, transfer the skillet off of direct heat and stir in 1/4 cup of grated parmesan
Taste and add additional salt or black pepper, if necessary
Slice the rested steak and serve with the white bean ragout
