Crab on toast is the lunch that exists in two completely different worlds. Done badly (overcooked toast, supermarket pasteurised crab, dry texture), it's a sad British seaside disappointment. Done properly (good sourdough, fresh crab from a fishmonger, lemon and chilli), it's one of the best 7-minute lunches you can make at home.
The recipe below is the proper version. The crab is the star, the toast is a vehicle, and the lemon and chilli are background players. Total work time, 7 minutes. Total ingredients, six. Cost per portion, around £6.
This is the dish we make on summer Saturdays at home, with a glass of cold Sancerre and a tomato salad on the side. It's also the lunch that introduces non-crab-eaters to good crab. Most converts come from this dish.
Key Takeaways
- Use 60/40 white to brown crab meat, never just white
- Sourdough toast must be deep golden, never pale
- Butter the toast generously while still hot
- Add lemon and chilli to the crab, not the toast
- 80g of crab per slice is the right portion
The Ingredients
Serves 2
- 2 thick slices of good sourdough bread
- 30g cold unsalted butter
- 100g fresh white crab meat
- 60g fresh brown crab meat
- 1 tbsp full-fat mayonnaise
- 1/2 small fresh red chilli (or pinch of chilli flakes)
- Juice of 1/2 lemon, plus zest
- 1 tsp finely chopped flat-leaf parsley
- Sea salt
- Freshly cracked black pepper
- A few flakes of Maldon sea salt for finishing
The crab quality matters most. Buy fresh white and brown meat from a fishmonger who picks it themselves. UK supermarket pasteurised crab has lost the sweetness that makes the dish work. The £8-10 you'll pay at a good fishmonger is the difference between excellent and mediocre.
The bread should be a proper artisan sourdough with a crisp crust and tangy interior. Pre-sliced supermarket "sourdough" is rarely properly fermented, the texture and flavour are wrong.
The Method, Step by Step
Step 1: Toast the Bread Properly
Toast the sourdough until deep golden brown on both sides. Crisp crust, slightly soft interior. Don't go pale, the contrast against the soft crab matters.
Step 2: Mix the Crab
In a small bowl, gently mix the white and brown crab meat with the mayonnaise. The brown meat does most of the flavour work. The white meat provides texture.
Add the lemon juice, lemon zest, finely chopped chilli, parsley, a small pinch of sea salt, and a few cracks of black pepper. Mix gently.
Taste. The seasoning should be balanced. If it tastes flat, add a tiny bit more salt. If too tangy, more brown crab meat.
Step 3: Butter the Toast Generously
While the toast is hot, spread cold butter generously. The bottom layer of butter melts into the toast, the top stays solid as a cushion for the crab.
Aim for around 8-10g of butter per slice. Generous, not stingy.
Step 4: Pile the Crab
Spoon the crab mixture onto each slice in a generous mound. Don't spread it flat. Leave it as a peak that sits proud of the toast.
Aim for around 80g of crab per slice.
Step 5: Finish
Add a few flakes of Maldon sea salt directly on the crab. Crack a tiny amount of black pepper. Squeeze a small amount of additional lemon juice if needed. Serve immediately.
Tips for Getting It Right
Don't skip the brown meat. Brown crab meat is where the flavour lives. Pure white meat is sweet but lacks depth. The 60/40 split of white to brown gives you the right balance.
Cold butter, hot toast. Cold butter on hot toast gives you two distinct layers: a melted bottom and a solid top. Pre-spread butter just merges with the toast and disappears.
Lemon both as juice and zest. The juice brightens the dish. The zest adds aromatic depth. Use both. The zest goes on the crab, not the toast.
Don't overmix. Crab meat should retain visible chunks of white meat. Overmixing turns it into a paste, killing the texture.
Don't pre-build. Crab on toast goes soggy within 5 minutes. Serve immediately, eat fast.
Variations and Pairings
With caviar: Add a small spoon (10g) of Beleaev Oscietra caviar on top of the crab. The salty pop against the sweet crab is one of the great combinations.
With avocado: Add a thin layer of mashed avocado between the toast and the crab. Adds creaminess and turns the dish into a more substantial lunch.
Asian style: Replace the parsley with finely chopped coriander, add 1 tsp of fish sauce, and use bird's-eye chilli instead of red chilli. A proper South-East Asian twist.
With pickled cucumber: Serve a small spoon of quick-pickled cucumber alongside (cucumber, rice vinegar, sugar, salt for 30 minutes). Cuts through the rich crab beautifully.
Wine pairing: A flinty Sancerre, a dry English Bacchus, or a glass of cold cider. Avoid red wines and heavy oaked whites.

Frequently Asked Questions
How much crab meat per person?
For lunch, 80g of crab meat per slice of toast is the right portion (160g per person if having 2 slices). For a starter, 60g per slice. Crab is rich and fillingly small portions go further than you might expect.
Can I use tinned crab?
Yes but the result will be inferior. Tinned crab is pasteurised, which kills the sweetness and fresh seafood character. The dish will be acceptable but not exceptional. If you must use tinned, look for premium chilled tubs from a proper fishmonger rather than long-shelf-life tinned cans.
What's the right bread?
A proper artisan sourdough with a crisp crust and tangy interior is the gold standard. White bloomer is the second choice. Avoid pre-sliced supermarket bread, the texture is too thin to hold the topping. Avoid heavy rye or pumpernickel, they fight the delicate crab.
Brown or white crab meat?
Both. The 60/40 white-to-brown split is the British classical proportion. Brown meat carries the flavour. White meat carries the texture. Skipping the brown meat is the most common mistake.
