Parisian-Style Steak Frites

1 . Stage

Heat vegetable oil in a heavy skillet over medium-high heat. Cook steaks to desired doneness, about 5 minutes per side for medium; an instant-read thermometer inserted into the center should read 130 degrees F (54 degrees C). Transfer steaks to a plate to rest.

2 . Stage

Place shallots in the skillet and cook until beginning to soften, about 2 minutes. Pour wine into the skillet and bring to a boil while scraping the browned bits of food off of the bottom of the pan with a wooden spoon. Add broth and anchovy; cook until thickened to sauce consistency, 2 to 3 minutes. Remove skillet from heat; whisk butter in gradually. Stir parsley, chervil, and thyme into the sauce. Purée sauce in the skillet with an immersion blender until smooth.

3 . Stage

Cut steaks into thin slices across the grain; spoon sauce over slices.
