Step 1: Preheat oven to 350 degrees F.
Step 2: Heat oil in heavy skillet (not non-stick) over medium-high heat.
Step 3: Combine 1 tablespoon rosemary, peppercorn and salt in a small bowl. Season steaks with peppercorn mixture, lightly pressing mixture to steak.
Step 4: Sear steaks 1-2 minutes on each side.
Step 5: Place in oven about 5-10 minutes for medium rare, or until steaks reach desired doneness.
Step 6: Allow steaks to rest 5 minutes before serving. (I covered mine is aluminum foil. After resting for a few minutes, I drained any juice from the steaks back into the pan, to use for the sauce).
Step 7: After removing steaks from pan, add shallots and garlic. Cook for 2 minutes on medium heat.
Step 8: Whisk in wine and mustard. Reduce by 2/3.
Step 9: Add remaining rosemary.
Step 10: Swirl butter (butter flour mixture) in pan to melt. If you added the flour to the butter let cook for a few minutes to let flour cook up. If needed add a little water if it becomes thick, to your desired consistency. (I like mine more like a thin gravy).
Step 11: Remove from heat.
Step 12: Add parsley and season with salt, to taste.
Step 13: Serve sauce over steak, and enjoy!
