Instructions
- 01
Make the Sweet Potato Mash: Boil sweet potato chunks in salted water for 15 minutes until tender. Drain well, mash with butter, milk, salt, and pepper until smooth. Keep warm.

- 02
Prep & Season Steak: Bring steaks to room temperature 30 minutes prior. Pat dry with paper towels, then season generously with salt and black pepper.

- 03
Sear the Steak: Heat oil in a heavy cast-iron skillet over medium-high heat until hot. Sear steak for 2–3 minutes per side for rare, 4 minutes per side for medium. Flip only once.

- 04
Baste with Garlic Butter: Add butter, crushed garlic, and fresh herbs in the last minute of cooking, spooning melted butter continuously over the steak.

- 05
Rest, Slice & Serve: Rest the steak on a board for 3–5 minutes so juices settle. Slice thinly and serve over a warm scoop of sweet potato mash.

- ✦Pat the steak dry before cooking, since dry meat browns much better.
- ✦Use a very hot pan so the outside gets a nice golden crust.
- ✦Turn the steak only once, so it doesn't dry out.
- ✦Always rest the steak for 3-5 minutes before slicing.
- ✦Season the mash well, because sweet potatoes need a little salt to bring out their flavor.
