Belgian Recipes
The Chilled Brasserie Classic
Tomate-crevette is the dish that shows up on every good Belgian brasserie menu, and for good reason. It is fresh, cold, and a little bit luxurious, built around the sweet North Sea grey shrimp that Belgians are rightly proud of. The magic is in the contrast: cool ripe tomato, delicate shrimp, and a mayonnaise bright enough with lemon that nothing tastes heavy.
I learned the hard way that this is a recipe about restraint. The first time I made it I drowned the shrimp in mayonnaise and skipped draining the tomatoes, and I ended up with a watery, gloopy plate. Done properly it is elegant and light, the sort of starter you can build in an hour without breaking a sweat.
Why This Tomate-Crevette Works
Tomate-crevette lives or dies on balance, and this version keeps all three parts in check: a firm, ripe tomato that holds its shape, tiny sweet shrimp that stay tender, and a lemony mayonnaise that binds without smothering. In proportion, every forkful tastes clean and bright rather than rich and claggy.
The single most important step is draining the tomatoes. After you hollow them out, you salt the insides lightly and turn them upside down so the excess juice runs out. Skip this and the water pools at the bottom of the shell, thins the mayonnaise, and leaves you with a puddle instead of a filling.
The homemade mayonnaise is the other quiet secret. It is quick to whisk together and you control the seasoning, so you can keep it light with plenty of lemon and a whisper of mustard. A good store-bought jar works in a pinch, but a fresh, lemony mayonnaise made in your own bowl is what lifts this from a lunch counter plate to something special. Because there is no real cooking, you can build the filling ahead and assemble just before serving, which is exactly why brasseries have leaned on it for generations.
Pro observation: The filling is dressed correctly when the shrimp look glossy and just coated, not swimming. If you can see mayonnaise pooling around them in the bowl, you have added too much; fold in a few more shrimp to bring it back.

Ingredient Notes & Substitutions
Tomatoes
Choose ripe but firm medium tomatoes that sit flat and hold their shape when hollowed. Very soft or overripe ones collapse under the filling. Round vine tomatoes are ideal; keep them at room temperature for the best flavor.
Grey Shrimp
Tiny North Sea grey shrimp are traditional and worth seeking out from a good fishmonger. Use certified halal cooked and peeled shrimp. If grey shrimp are hard to find, small cooked halal cold-water shrimp are the closest easy swap.
The Mayonnaise
A fresh egg yolk, a little Dijon, lemon, and neutral oil make a light mayonnaise you can season to taste. Have everything at room temperature so it emulsifies smoothly, or use a good store-bought halal mayonnaise brightened with lemon.
Lemon & Parsley
Fresh lemon juice keeps the filling from tasting heavy, so add it to taste. Finely chopped flat-leaf parsley adds color and a clean, grassy note. Chives or a little tarragon make pleasant alternatives.

Before You Start
1. Bring the mayonnaise ingredients to room temperature. A cold egg yolk and cold oil are the usual reason a homemade mayonnaise fails to come together, so take them out ahead of time.
2. Keep the shrimp cold until the last moment. Grey shrimp are delicate, so leave them covered in the refrigerator until you fold them into the mayonnaise.
3. Plan for the draining time. The hollowed tomatoes need about ten minutes upside down to shed their juice, so start them first.
Step-by-Step Instructions
Hollow and Drain the Tomatoes
Slice a thin lid off the top of each tomato and set the hats aside. With a teaspoon, gently scoop out the seeds and soft core, leaving a sturdy shell. Sprinkle the insides with a little salt, then set the shells upside down on paper towels to drain for about 10 minutes. This is the step that keeps your tomate-crevette crisp instead of watery.
Whisk the Lemony Mayonnaise
In a bowl, whisk the room-temperature egg yolk with the Dijon mustard and a pinch of salt. Add the sunflower oil a few drops at a time at first, whisking constantly, then in a slow steady stream as the mixture thickens into a glossy mayonnaise. Whisk in the lemon juice and white pepper. Taste and adjust with a little more lemon so it stays bright.
Check the Shrimp
Tip the cooked peeled grey shrimp onto a plate lined with paper towel and pat them gently dry. Pick through them to remove any stray bits of shell. Keeping them dry stops extra liquid from thinning the mayonnaise once everything comes together.
Fold the Shrimp into the Mayonnaise
Add most of the mayonnaise to the shrimp along with the chopped parsley and fold gently with a spoon. You want the shrimp just coated and glossy, not swimming, so add the mayonnaise in stages and stop while the mixture still looks light. Taste and adjust the salt, pepper, and lemon.
Fill the Tomatoes
Blot the inside of each drained tomato shell one more time with paper towel. Spoon the shrimp filling generously into each one, mounding it slightly above the rim. Set the reserved tomato hat on top at a jaunty angle so the filling peeks out from underneath.
Chill and Serve
Rest the filled tomatoes in the refrigerator for about 30 minutes so they are properly cold and the flavors settle. To serve, set each on a lettuce leaf with a lemon wedge alongside, and add fries or good bread on the side. Serve straight from the cold, and do not let them sit out at room temperature.
Chef’s Tips From Real Kitchen Testing
Always drain the hollowed tomatoes upside down and blot them dry before filling. That trapped juice is the number one cause of a watery, sliding filling.
Dress the shrimp in stages. Start with less mayonnaise than you think you need, then add more only if it looks dry. That is far easier than rescuing an over-dressed bowl.
Keep everything cold. Shrimp are delicate, so work quickly, return the filling to the refrigerator between steps, and serve the tomatoes straight from the cold.

Make-Ahead Tips
The shrimp filling can be mixed a few hours ahead and kept covered in the refrigerator, which helps the flavors settle, and the tomato shells can be hollowed, salted, and drained ahead too. Fill the tomatoes no more than an hour or two before serving so the shells stay firm, and keep everything cold until you plate it.
Storage & Food Safety
Common Mistakes to Avoid
Troubleshooting
Filling turned watery? The tomatoes were not drained enough, or the shrimp were damp. Blot both dry, drain off any liquid, and fold in a little extra shrimp to firm it up.
Mayonnaise split or greasy? The oil went in too fast or the yolk was cold. Start a fresh yolk in a clean bowl and whisk the broken mixture into it drop by drop.
Tastes flat or heavy? It usually needs a squeeze more lemon and a pinch of salt to lift the shrimp and cut the richness of the mayonnaise.
A Note on Belgian Cooking
Along the Belgian coast, tiny grey shrimp are hauled from the cold North Sea and cooked right on the boats, which gives them their sweet, briny character. Belgians treasure these shrimp, and tomate-crevette is one of the purest ways to show them off: nothing more than a ripe tomato, a light homemade mayonnaise, and a generous heap of shrimp. It is a brasserie fixture, served as a starter or a light lunch with fries and a lettuce leaf.
