Compound Butter
Steakhouse Butter

Softened butter mashed with garlic, herbs, and lemon, rolled into a log and chilled — slice a coin onto a hot steak and it melts into an instant, glossy sauce. Barely a recipe, endlessly useful.

Ingredients

Soft, not melted — that's the whole trick. Let the butter come fully to room temperature so it's spreadably soft but still holds its shape; then it whips up smooth and the flavorings stir through evenly. If it melts (so don't microwave it soft), the butter separates and won't set into a clean, sliceable log. Everything past that is just stirring.

Easier, if you like

  • Softening in a pinch: cut the butter into small cubes and spread them out — they'll come to room temperature in about 15 minutes, no microwave (which melts it) required.
  • No fresh herbs? Dried work in a smaller amount — about 1 tsp dried mixed herbs for the 2 tbsp fresh — mashed straight in. A grate of garlic and lemon zest still make it taste fresh.

Method

    Cook's notes

    Soft, not melted — the one rule. (Worth repeating, because it's the only way this goes wrong.) Room-temperature butter mixes smooth and sets into clean slices; melted butter separates and turns grainy.

    It keeps beautifully — that's the point of a batch. Wrapped tight, the log lasts 1–2 weeks in the fridge and up to 3 months in the freezer. Slice coins straight off the frozen log as you need them; no need to thaw the whole thing.

    Use unsalted butter so you control the salt. If all you have is salted butter, skip the added salt and just season to taste at the end.

    It's not only for steak. A melting coin is gorgeous on a reverse-seared ribeye, a baked potato, steamed broccoli, corn on the cob, grilled fish, a warm dinner roll, or scrambled eggs.

    Make it your own — a few combinations to try:
    • Garlic-herb (the recipe above) — the all-purpose steakhouse butter.
    • Blue cheese & chive — mash in 30 g crumbled blue cheese; unbeatable on beef.
    • Roasted garlic — swap the raw clove for the soft mashed cloves of a whole roasted head; mellow and sweet.
    • Horseradish-Dijon — 1 tbsp prepared horseradish plus the Dijon; a sharp foil for ribeye and prime rib.
    • Chili-lime — lime zest, a pinch of chipotle or chili powder, and cilantro; made for corn and fish.
    • Maître d'hôtel — the French classic, and the ancestor of all of these: just parsley, lemon, salt, and pepper.

    Vegetarian and gluten-free as written; easy to make dairy-free

    Dairy-free: a good plant butter (Miyoko's or Country Crock Plant Butter sticks) softens and rolls the same way — flavor it identically.

    Gluten-free / vegetarian: naturally both, as written.
