Steak & Buttery Mash
Pan-seared ribeye with a garlic-thyme butter baste, over mash that is more butter than potato.
Ingredients
Scaled for 2 people
- Ribeye steak (2.5cm / 1in thick)2 steaks
- Floury potatoes (Maris Piper / Russet)600 g
- Butter100 g
- Whole milk80 ml
- Garlic cloves3 cloves
- Fresh thyme4 sprigs
- Neutral oil1 tbsp
- Flaky sea saltto taste
- Black pepperto taste
Method
- Take the steaks out of the fridge 45 minutes before cooking. A cold centre is the #1 cause of a grey, overdone crust. Pat them bone dry with kitchen paper.
- Peel and quarter the potatoes. Start them in cold salted water, bring to a boil, then simmer 18–20 min until a knife slides through with no resistance.
- Salt the steaks generously on both sides just before they hit the pan. Get a heavy skillet (cast iron if you have it) ripping hot with the oil — it should be shimmering, almost smoking.
- Lay the steaks away from you. Do not move them for 2 minutes. Flip, then add the butter, smashed garlic and thyme. Tilt the pan and spoon the foaming butter over the steak continuously.
- Cook to your target temperature (see the doneness chart below), then move to a board or warm plate.
- Rest for at least 5 minutes, loosely tented with foil. Skipping this dumps all the juice onto your board.
- Drain the potatoes and let them steam-dry in the empty pan for 1 min. Rice or mash them, then beat in the butter first, then the warm milk. Season hard — mash needs more salt than you think.
- Slice the steak against the grain, spoon over any resting juices plus the pan butter, and serve on the mash.
Buy one thick steak instead of two thin ones for 2 people and slice it to share — thick steaks are far more forgiving.
Steak doneness — per side, 2.5cm / 1in thick
Blue
Seared crust, cool and near-raw red centre. Only worth it on very fresh, thick-cut steak.
Rare
Bright red centre, warm rather than hot, very juicy and soft throughout.
Medium rare
The default for a reason. Warm red-pink centre, maximum juiciness, fat has started to render.
Medium
Hot pink centre with a wider brown band. Still juicy, noticeably firmer bite.
Medium well
A faint blush of pink at the very centre. Getting dry — go for a fattier cut if you cook to here.
Well done
No pink, fully firm. Use a thinner cut and lower heat, and rest it just as long.
Pull the steak 3°C / 5°F below your target — it keeps cooking while it rests. Full guide on the Steak guide page.
