In a cast iron skillet, saute the anchovies in butter until soft and pulpy.
Once the anchovies are soft, add the grated garlic and saute for 1 minute.
Add the thyme & parsley to the pan and heat through. Add the vinegar and cook for 1 more minute until all ingredients are combined and the liquid has evaporated. Remove the anchovy mix into a side dish and allow to cool.
Once the anchovy mix has cooled, add the olive oil to the dish and stir together to make a thick sauce. Serve on top of the seared steak.
Steak
Wipe the cast iron skillet clean from the anchoiade and reset on the stove to medium-high heat.
Lightly season the steak, keeping in mind that the anchoiade is quite salty.
Melt 1 tablespoon of butter in the skillet, add the steaks to the pan. Sear on high-heat until one side has a nice golden crust (about 3 minutes). Flip the steak and sear on the other side.
Add the remaining 2 tablespoons to the pan and melt the butter. Tip the pan upward to gather the butter at the bottom, then using a serving spoon, scoop the butter and baste the steaks. Do this until most of the butter has been absorbed into the steaks.
Cook the steak to almost your desired doneness. Then, remove the steak from the pan, cover, and allow to rest for 5-10 minutes. Once rested, serve the steak with the l'anchoiade sauce.
TIP: If you have extra sauce, refrigerate to latter serve with other dishes like grilled bread or veggies, or blend smooth for an excellent dip for fries.
