Method
Garlic Truffle Butter & Rosemary
Make butter
In a medium bowl, combine the softened unsalted butter, minced garlic, chopped rosemary, lemon zest, fine sea salt, and freshly ground black pepper. Stir with a fork until fully incorporated and smooth.
Add the black truffle oil a little at a time, tasting as you go, until the butter has a subtle truffle aroma (about 1 tsp total). Do not overdo truffle oil; you want an elegant hint.
Transfer the compound butter to plastic wrap or parchment, shape into a log (about 1 inch diameter), roll tightly, and chill in refrigerator for at least 30 minutes to firm. You can leave some butter at room temperature (10 minutes) before serving to soften slightly.
French-cut Fries
Prep and soak
Cut peeled russet potatoes into French-cut fries (about 1/3 inch thick, lengthwise). Place cut fries in a large bowl and cover with cold water and 1 tsp fine sea salt. Soak in the refrigerator for 30–60 minutes to remove excess starch.
Second fry (finish)
Increase oil temperature to 375°F (190°C). Fry the blanched fries in small batches for 2–3 minutes until golden and crisp. Drain on paper towels or a rack, immediately season with flaky sea salt and a light dusting of freshly ground black pepper. Keep warm in a single layer in a low oven (200°F / 95°C) if needed.
Steak
Bring steaks to room temp & season
Remove steaks from the refrigerator 30–45 minutes before cooking to come to room temperature. Pat dry with paper towels. Season both sides generously with kosher salt and freshly ground black pepper.
Reduce heat to medium-high. Add two slices (about 2 tbs) of the prepared truffle rosemary butter to the pan and a small sprig of rosemary if available. Tilt the pan and spoon the melted butter over the steaks (baste) for 1–2 minutes. For doneness guidance: 120–125°F for rare, 130–135°F for medium-rare, 140–145°F for medium (use an instant-read thermometer).
Remove steaks from the pan and rest on a cutting board for 5–8 minutes, tented loosely with foil. While resting, top each steak with a 1-inch slice of the chilled truffle butter log so it melts over the surface.
Finishing & Plating
Slice the rested steaks against the grain (optional) or serve whole. Arrange a generous portion of French-cut fries alongside each steak.
Drizzle a scant 1/2 tsp extra truffle oil over the fries or steak if desired for extra aroma. Sprinkle microgreens or chopped parsley over the fries and steak for color.
