Sesame Shrimp Tartines with Lime & Cucumber

Toast the sesame seeds first. Medium-low heat. Don’t look away. That second you check your phone is the second they burn. Once they smell nutty and alive, pull them off the pan. Cool for a minute.

Why You’ll Love This Sesame Shrimp Tartine

Takes 45 minutes total — 30 minutes of chopping, 15 minutes to actually cook. Not bad for something that looks like you spent all afternoon on it.

Open-faced. No folding. No mess on your hands. Just pick it up and eat the whole thing.

The bread gets actually crispy. Not just toasted. The sesame crust snaps when you bite it. Then it goes soft where the avocado and shrimp sit. Two textures at once.

Shrimp and cucumber is a pairing that works cold, at room temp, doesn’t matter. Lime keeps everything tasting bright even after sitting five minutes.

Works as an appetizer for company. Works as lunch. Works cold the next day if you reheat the bread separately — keep the toppings on the side until right before eating.

What You Need for Sesame Shrimp Tartines

Black and white sesame seeds. Toasted already or you toast them yourself. Toasted matters — raw ones taste flat.

Mayo. Japanese mayo if you have it — it’s richer, holds the seeds better. Regular mayo works fine.

Fresh Nordic shrimp. Half a pound. Peeled, tails off. If they’re frozen, thaw them and pat them completely dry. Wet shrimp makes the whole thing soggy.

Lebanese cucumbers. Smaller than regular ones. Diced small. Regular cucumber works if that’s what’s there — just peel it and scoop out the seeds so it’s not watery.

Lime. One whole one. You need both the zest and the juice.

Pickled ginger. A tablespoon chopped up. You can use fresh ginger instead if pickled isn’t around — just add a splash of rice vinegar to cut the raw edge.

Sriracha. A tablespoon plus a teaspoon. Or less. Depends how much heat you want.

Scallion. One small one. Minced fine.

Vegetable oil. Just a tablespoon. Keeps everything from sticking.

Avocados. Two of them. Ripe but firm. If they’re too soft they just mash into the shrimp and disappear.

Four slices of sandwich bread. Crusts on. Keep them plain — white, wheat, sourdough, doesn’t matter as long as they’re sturdy enough to hold weight.

How to Make Sesame Shrimp Tartines

Spread mayo on each bread slice thin. You’re not making a sandwich mayo situation here — just enough so the seeds stick. Both sides.

Press each slice mayo-side down into the sesame mixture. Really press it. You want the seeds to coat completely, not just sit on top. Flip it over, sesame side up, onto a clean sheet or plate.

Preheat the air fryer to 365 degrees. Three or four minutes. The pan getting hot matters more than you think.

Arrange the bread in a single layer in the basket. No overlap. Air needs room to move around everything or it steams instead of crisping. You might be able to fit two slices, might only fit one. Depends on your basket size.

Cook for nine to thirteen minutes. Watch it. You’ll hear it crackle at the edges when it’s close. The sesame should look toasty brown. The bread should be golden but not burnt. You learn the difference by watching it once.

While the bread’s going, deal with the shrimp. Toss it in a bowl with the cucumber, scallion, lime juice, lime zest, ginger, sriracha, oil. Salt it. Cracked pepper. Taste it. If it needs more acid, add more lime. If it needs more heat, add more sriracha. Don’t add mayo yet. Mayo makes it mushy.

When the bread comes out, it’s hot. Avocado slices go on top while it’s warm. Softens them a little.

Spoon the shrimp mixture over the avocado. Drizzle extra mayo on top if you want it, or just leave it as is.

Eat it immediately. The crunch is the whole point. Waiting five minutes and the bread gets soft from the moisture in everything else.

Air Fried Sesame Shrimp Toast Tips and Common Mistakes

Don’t crowd the basket. Sounds obvious. People do it anyway. You end up with bread that’s crispy on one side and barely warm on the other.

The shrimp mixture can sit for a few minutes before you assemble. The tartines can’t. The bread gets weird after sitting topped. Toast first, top last.

If you don’t have an air fryer, use the toaster oven on broil. Watch it. Closer heat means faster browning and faster burning. Usually six to eight minutes instead of nine to thirteen. Or use a dry skillet — cast iron works best. Medium-high heat, two minutes per side. Less even but it works.

Pickled ginger versus fresh ginger is a real choice. Pickled is salty and sweet and tangy. Fresh is sharp. Both work. If you’re using fresh, add that splash of rice vinegar so it doesn’t taste too harsh.

The shrimp can be replaced. Crab. Scallops. Even cooked white fish if you chop it fine. The tartine itself is the star — the protein is just what happens to sit on top.

Total:

45 min

Servings:

4 servings

Ingredients

• 75 g (scant 1/2 cup) black and white sesame seeds, toasted gently in pan
• 4 sandwich slices, crusts intact
• 80 ml (about 1/3 cup plus 1 tbsp) Japanese mayonnaise or regular mayo; extra for serving
• 225 g (1/2 lb) fresh Nordic shrimp, peeled, tails off; thawed if frozen and patted dry
• 2 Lebanese cucumbers, diced small
• 1 lime, zested finely and juiced
• 1 small scallion, minced fine
• 15 ml (1 tbsp) light vegetable oil
• 20 ml (1 tbsp plus 1 tsp) chopped pickled ginger (substitute with fresh minced ginger if unavailable)
• 7 ml (1 1/2 tsp) sriracha, adjust heat as desired
• 2 ripe yet firm avocados, sliced lengthwise

Method

1. 1 Toast sesame seeds first in a dry pan uncovered, medium-low heat, constantly stirring to avoid burning. Once fragrant, remove from heat and cool.
2. 2 Spread a thin, even layer of mayonnaise on each bread slice. Don’t soak it; just enough to hold seeds.
3. 3 Press mayo-coated bread slices gently into the sesame seed mixture, mayo side down, coating completely. Flip slices back, sesame side up, on clean sheet.
4. 4 Preheat air fryer at 185 °C (365 °F) for 3-4 minutes beforehand.
5. 5 Arrange sesame-coated bread in a single layer in the fryer basket. Avoid overlap or crowding — air needs to circulate.
6. 6 Cook 9-13 minutes, watching bread surface–should turn golden brown, sesame seeds toasty. Listen for crackling edge sounds, a good indicator.
7. 7 Meanwhile, in a bowl, toss shrimp, cucumber, scallion, lime juice and zest, oil, sriracha, and chopped ginger. Salt and freshly cracked pepper to taste. No mayo yet; keep this a firm, fresh salad.
8. 8 Taste and adjust acidity or heat. Adding too much mayo here makes it too mushy. I prefer layering mayo separately.
9. 9 When bread is done, remove quickly; sesame crust crisp but not burnt.
10. 10 Layer avocado slices generously atop warm toasts.
11. 11 Spoon shrimp salad over avocados, drizzle extra mayo if wanted.
12. 12 Serve immediately — the crunch is crucial, so no waiting.
13. 13 If no air fryer, use toaster oven on broil, watching closely. Or pan-fry in a dry skillet but less even toasting.
14. 14 Substitutions: Pickled ginger can be fresh minced ginger with splash of rice vinegar for tang. Lebanese cucumbers replace with English cucumber or regular seeded cucumber if peeled well.
15. 15 Shrimp can be replaced by spiced cooked crab meat or cooked scallops for different surf flavor.

Frequently Asked Questions About Sesame Shrimp Tartines

Can I make these ahead? Not the whole thing. Toast the bread and coat it with sesame up to an hour ahead. Keep it uncovered at room temp so it stays crispy. Make the shrimp salad the day before. But don’t assemble until right before eating. That’s non-negotiable.

What if the shrimp is still frozen? Thaw it in the fridge the night before. If you’re rushed, cold water works — thirty minutes in a bowl. Then pat it really dry on paper towels. Wet shrimp ruins everything.

Can I use regular cucumber instead of Lebanese? Yeah. Just peel it and scoop out the watery seeds with a spoon. Regular cucumber’s got way more water inside. Does the same job once you deal with that.

Why not add mayo to the shrimp mixture? Because it breaks down the texture. Lime juice is acidic. Mayo can split. The salad becomes mushy. Layer the mayo separately — either on the toast under the avocado or drizzled on top. It keeps everything where it should be.

How hot does this get? Depends on the sriracha amount. Start with a tablespoon and taste it. If you want it spicier, add more. Not much else in here to balance heat, so the sriracha is the main flavor you’re adjusting.

Do I have to use Japanese mayo? No. Regular mayo works. Japanese mayo has more egg yolk and oil so it’s thicker and richer. Regular mayo is thinner — you might need slightly less so you’re not oversaturating the bread. But the tartine tastes good either way.

Can I toast the sesame seeds ahead? Yes. Toast them, cool them completely, then store them in an airtight container for a few days. They stay crisp. Whole thing takes one minute in the pan anyway so it’s not like you’re saving much time, but it works if you want.
