The honest weeknight steak: lean, affordable, and excellent when not overcooked — sous-vide was practically invented for it. Here, cooked to the exact degree in a water bath, then flash-seared — physically impossible to overcook.

Prep checklist
Sirloin Steak — 250 g, 2.5 cm thick
Whole Black Peppercorns — coarsely cracked
Garlic — smashed
4 steps
Method
1
Season the steak with kosher salt, bag it with the thyme and a smashed garlic clove, and lower the open bag into the water to press the air out before sealing (the water-displacement trick — no vacuum sealer needed).
Learn the technique ›
2
Cook in a 54.5°C water bath for 1.5–3 hours. Time is forgiving here — the steak physically cannot pass the bath temperature; that's the entire magic of sous-vide.
💡
54.5°C = medium-rare. Prefer medium? Set 58°C. Rare? 52°C. The bath temperature IS the doneness dial.
3
Remove from the bag and pat obsessively dry — surface moisture is the enemy of the crust you're about to build.
💡
A damp sous-vide steak will grey-steam in the pan. Dry it like you mean it, top, bottom, and edges.
4
Sear in a screaming-hot pan with high-smoke-point oil: 45–60 seconds per side with the butter added for the last 30 seconds. No need to rest more than a minute or two — the interior is already even.

From the chef
Notes
Buy this cut from a butcher who cuts to order; even seasoning and a real rest do the rest.
Afterwards
Keep, reheat & pair
Storage
Refrigerate in an airtight container up to 3 days; reheat gently with a splash of water.
Freezing
Freezes well up to 2 months. Thaw overnight in the fridge before reheating.
Reheating
Leftover steak hates reheating. Slice it cold over salad, or warm gently in a 120°C oven to 45°C and flash in a hot pan for 30 seconds.
Make ahead
Salt up to 24 hours ahead, uncovered in the fridge — it seasons deeper and dries the surface for a better crust.
Wine pairing
A juicy Syrah or a good Merlot; leaner cuts don't need a tannin hammer.
Beer pairing
A malty amber ale or porter echoes the crust; keep hop bombs away from beef.

FAQ
How do I hit the doneness I want?
Pull the steak 3°C below target — it climbs while resting. Rare: pull 47°C, serve 49–52°C (cool red center). Medium-rare: pull 51°C, serve 54–57°C (warm red — the steakhouse default). Medium: pull 57°C, serve 60–63°C (pink, firmer). Medium-well: pull 63°C, serve 65–68°C (a whisper of pink). Well-done: 71°C+ — cook it slower and gentler to keep any juice. An instant-read thermometer beats every finger trick ever invented.
Why rest the steak, and for how long?
Heat drives the juices toward the center; resting lets the muscle relax and reabsorb them. Cut too early and they flood the board instead of staying in the meat. Rest 5 minutes for a standard steak, 10+ for thick cuts and roasts — loosely covered, never wrapped tight (trapped steam softens your crust).
When it goes sideways
Troubleshooting
A thick grey band under the crust. The pan was too cool or the steak cooked too long over direct heat. Sear hotter and faster — or use the reverse sear, which nearly eliminates the band.
No crust, just grey. The surface was wet or the pan wasn't hot enough. Pat aggressively dry, salt ahead, and wait for the oil to shimmer before the steak touches metal.
Chewy even at medium-rare. Almost always a slicing error — cut thinner and strictly against the grain. On loose-grained cuts the grain direction is visible; follow it.
Smoke alarm going off. Normal for a hard sear. Open a window, use an oil with a high smoke point (avocado, grapeseed), and skip the butter until the final minutes.
