Grey shrimp (Crangon crangon) have been fished along the West Flanders coast for centuries. The horseback shrimp fishing tradition at Oostduinkerke was inscribed on UNESCO's Intangible Cultural Heritage list in 2013. The modern tomato-and-shrimp presentation took shape in Belgium through the mid-20th century and is documented in classic compilations of Belgian recipes, including Jacques Andrieu Delille's La Cuisine belge. Today the dish is served across the country—from Brussels brasseries to seaside cafés in Ostend—and is recognised by Belgian food writers as a defining emblem of the national café table, with quality measured by shrimp abundance.
Cold, sweet, briny grey shrimp meet a cloud of creamy mayo inside a cool, acidic tomato shell—deceptively simple and unmistakably Belgian.
The tomato must drain cut-side down for at least 15 minutes so excess water does not dilute the mayonnaise emulsion. Grey shrimp stay firm thanks to their cold North Sea habitat; their dense texture holds up against the egg-oil emulsion without softening. Lemon juice provides gentle acidity that prevents the mayo from tasting heavy and counters oxidation.
Variations
Some brasseries add minced celery or cucumber for crunch; upscale restaurants may use tarragon-flavored mayonnaise or top with a slice of smoked salmon. In Wallonia the dish is often paired with hard-boiled egg halves. Mustard mayo is a common home-cook addition.

How it's made
7 steps · 25 min active + 40 min waiting
- 110 min
If purchased shell-on, peel grey shrimp carefully and set aside.
- 25 min
Slice tops off tomatoes and scoop out seeds and pulp with a spoon.
- 315 min
Salt lightly inside each tomato cavity and place cut-side down on a rack to drain for 15 minutes.
Watch outDrain the salted tomato cavities cut-side down at least 15 minutes — leftover water thins the mayo into a runny mess in the shell.
- 45 min
Combine shrimp with mayonnaise, finely minced parsley, a squeeze of lemon juice, salt, and black pepper; stir gently.
Watch outFold the shrimp into the mayo gently — overmix and the delicate grey shrimp break up and the salad turns to paste.

Pat tomato cavities dry with paper towel.
- 63 min
Fill each tomato generously with the shrimp mixture; replace the top at an angle as garnish.
- 725 min
