Cut a 2.5-3 cm thick steak from the beef shoulder and let it sit at room temperature.
Heat olive oil in a frying pan and place the steak in it. Add thyme and rosemary to the pan. Fry the steak for 5 minutes on each side over medium heat, add salt and pepper to taste.
Place a piece of butter on top of the steak. Add the vegetables to the meat and fry everything together for a few more minutes. Remove the steak from the pan and let it rest, while you cook the vegetables until done.
Prepare the sauce. To do this, fry the chopped onion and garlic in butter in a thick-bottomed saucepan for 2-3 minutes until golden brown. Add white wine and cream to the saucepan. When the sauce boils, add the Dor Blue cheese and stir. Simmer the sauce for 3-4 minutes over medium heat until thickened and the cheese melts.
Place the steak and vegetables on a serving plate or board and serve with the sauce. Done. Enjoy!
