Braw Langoustines on Sourdough wi' Brown Butter an' Thyme
When the West Coast delivers, you stop faffing and fry.
June to August, the langoustines are in — fat, meaty things that barely need looking at. I've been doing this one for twenty years: butter, heat, salt, toast. The brown bits at the bottom of the pan are where the magic lives, and I'll not hear otherwise. One slip: don't overcook them or you're eating rubber.
How to Cook It
- 01
Toast the bread proper
Slice your sourdough thick — about 2cm. Toast it in a dry pan over medium heat, both sides, until golden and crisp but not charred. You want it to hold up to butter and juices without collapsing like a damp biscuit. Set aside on a warm plate.

Melt butter into brown
In a large heavy-bottomed pan, melt the butter over medium-high heat. Don't rush it. Watch — it'll foam, then settle, then the solids drop and turn nutty and dark. This takes about 3–4 minutes. You'll smell almonds and caramel. The moment it stops foaming and the bits are golden, you're there. Don't let it go black.
~4 min - 03
Season and ready the langoustines
Dry them with a cloth — any moisture stops them browning. Season both sides with sea salt and pepper. Crush the thyme sprigs between your palms to release the oils, then drop them into the brown butter. The smell should make you stop and breathe.

Sear the langoustines
Heat the pan to medium-high (the butter should shimmer, not smoke). Place the langoustines flat-side down and sear for 90 seconds — you want a kiss of colour. Flip and sear the other side for another 90 seconds. They'll turn from translucent to opaque. That's done. Don't poke them — they'll tell you when they're ready by feeling firm but tender to the touch.

Pull it together
Remove the pan from heat. Squeeze lemon juice over the langoustines and let it sizzle into the butter for 10 seconds. Taste the pan juices — adjust salt. Lay each piece of toast on a warm plate. Top with three langoustines per serving, dress with a spoonful of the brown butter and thyme, and scatter parsley over.

“Warm plate. Toast down, langoustines splayed on top like they're sunbathing. Spoon the brown butter (with the thyme sprigs and golden solids) over and around. No faffing. The lemon should glisten. One wedge of lemon on the side for squeezing. Parsley for colour and freshness — it stops the plate looking like it's drowning.”
First bite: the toasted bread gives you crunch, the langoustine melts like warm butter itself, and the brown butter hits you with nutty, caramelised depth. The thyme creeps in on the mid-palate — herbal, almost minty. The lemon cuts through at the end, sharp and alive. It's summer on a plate, basically.
Swap the langoustines for hand-dived Scottish scallops (vegan when they're not harvested using dredges that disturb the seabed) or, more reliably, fat oyster mushrooms sliced thick and seared hard in brown butter made from vegan butter (Naturli or similar). The brown butter technique works just as well — the mushrooms soak up the nutty caramelisation and give you that meaty texture. Thyme, lemon, and toast carry the dish. You lose the brine but gain an earthy sweetness that's honest.
Dry, saline, mineral — mirrors the sea without shouting over the butter. Chilled, not cold.
Scottish or continental — crisp enough to cut the richness, light enough not to bully the seafood.
Not fancy, just honest. The bubbles keep you company and the salt nods to the sea.
- ·Don't fidget with the langoustines — they brown faster if you leave them alone.
- ·Brown butter waits for no one; have your toast and plate ready before you start the pan.
- ·A squeeze of lemon at the table beats it in the kitchen — let people choose.
