Steakhouse herb butter is the trick that makes a home steak taste like it came off a grill line: one rosemary sprig and three thyme sprigs stripped, a small handful of parsley and two garlic cloves, all chopped as finely as you have patience for, smeared and folded into 200 g of soft butter with a scraper until the green runs through every bit, then a splash of Worcestershire for the savory note underneath. Rolled into a log in cling film and chilled firm, it goes on after the steak leaves the pan — a slice melting over the resting meat. One batch finishes several steaks and keeps for weeks. Makes about 10 slices.
Instructions
- 1
Strip the rosemary and thyme leaves from their stems and gather them on the board.
- 2
Add the parsley and garlic and chop it all together as finely as you have patience for — the finer, the better.
- 3
Put the soft butter straight onto the pile and smear and fold with a scraper until the green runs through every bit of it.
- 4
Add a splash of Worcestershire sauce and work it through.
- 5
Place the butter on cling film, roll it into a log and chill until firm.
60:00 - 6
Slice a round onto each steak after it leaves the pan and let it melt while the meat rests.

Notes from our kitchen
Soft butter is the whole technique — cold butter tears instead of taking the herbs, and melted butter drops them to the bottom. Chop finer than feels necessary: big flecks of rosemary stay woody on the tongue, fine ones perfume the whole log. The Worcestershire is what makes it taste of more than butter; a splash, not a pour, or the log goes grey and salty. And it goes on the steak after the pan, never in it — the herbs burn at searing heat.
Variations
- Mellower garlic. Raw garlic bites in cold butter. Grate it and warm it 30–60 seconds in a spoon of the butter without coloring, cool, then fold it in with the rest — the Notion recipe card suggests this and it rounds the log noticeably.
- Deeper steakhouse lean. A teaspoon of Dijon alongside the Worcestershire pushes it toward the classic maître d’hôtel butter. Keep the herbs as filmed; the rosemary-thyme-parsley trio is the flavor the steak is dressed for.
Frequently Asked Questions
Why does the butter go on after cooking, not in the pan?
At searing temperatures the herbs and garlic in the log would scorch and the milk solids burn before the crust forms. Sliced onto the hot steak as it rests, it melts slowly into the surface — you get the fragrant rosemary and garlic kick intact. The pan gets plain butter and a crushed clove for basting instead.
How long does the log keep?
Wrapped tight in cling film, about two weeks in the fridge and three months in the freezer — slice rounds straight from frozen. One batch is deliberately enough to finish several steaks, which is why it is worth making ahead.
What else is it good on?
Anything that likes garlic butter: grilled chicken, roasted potatoes, corn on the cob, a piece of fish under the broiler, or simply melted over toast. The Worcestershire keeps it savory enough for meat and vegetables alike.
