Spicy Crab Salad with Cucumber

This spicy crab salad is made with lump crab meat, crisp cucumber, avocado, fresh herbs and a creamy sriracha dressing. It’s fresh, a little spicy and packed with protein...and you don’t have to cook anything. My ideal summer meal, honestly.

The dressing is a mix of Greek yogurt, Kewpie mayo, sriracha, soy sauce, sesame oil and lime. It’s creamy without being too heavy, and the cucumber gives the whole thing a really good crunch. I add furikake, sesame seeds and sometimes chili crisp on top because apparently one spicy condiment is not enough for me.

You can eat this crab and cucumber salad on its own, pile it into lettuce cups or serve it with rice for a more filling meal. It also makes a great appetizer if you scoop it onto cucumber slices or crispy wonton cups.

Why You’ll Love This Recipe

• It has nearly 30 grams of protein per serving. The lump crab and Greek yogurt make this a really satisfying lunch without weighing it down.
• The dressing is so good. Kewpie mayo makes it rich, Greek yogurt keeps it light and sriracha brings the heat.

• You can serve it a bunch of ways. Eat it as a salad, spoon it into lettuce cups or turn it into a rice bowl.

Is Spicy Crab Salad the Same as Kani Salad?

Not exactly. Kani salad is usually made with shredded imitation crab, julienned cucumber and a creamy Japanese-style mayonnaise dressing. This spicy crab salad uses real lump crab meat and larger pieces of cucumber and avocado.

The flavors are definitely similar. Both usually include Kewpie mayo, sriracha, sesame and cucumber. The texture and main ingredient are what make this version different.

You can use imitation crab here if that’s what you have, but it will taste sweeter and have a firmer, more processed texture than lump crab. It will also turn this into something much closer to a traditional spicy kani salad.

Spicy Crab Salad Ingredients

You’ll only need a few simple ingredients to make this recipe. The exact measurements are listed in the recipe card below. Here’s an overview of what you’ll need:

• Lump crab meat: Look for refrigerated lump crab meat and check it carefully for any small pieces of shell. Try not to break up those nice chunks while mixing.
• English cucumbers: These are crisp, have thin skin and contain fewer seeds than standard cucumbers. You don’t need to peel them.
• Scallions and cilantro: These add freshness and keep the creamy dressing from tasting too heavy.
• Jalapeño: Totally optional, especially since the dressing already contains sriracha. Remove the seeds for less heat or leave them in if you want it spicy.
• Avocado: This adds creaminess and makes the salad more filling. Use an avocado that is ripe but still firm so it doesn’t disappear into the dressing.
• Greek yogurt: Nonfat Greek yogurt lightens up the dressing while keeping it creamy.
• Kewpie mayonnaise: Kewpie is richer and slightly sweeter than American mayonnaise. Regular or light mayo works too.
• Sriracha: One tablespoon gives the dressing a noticeable but manageable kick. Add more if you want.
• Soy sauce: This adds salt and umami. Use tamari if you need the recipe to be gluten-free.
• Rice vinegar and lime: Both add acidity, which the crab and creamy dressing really need.
• Sesame oil: A little goes a long way. Make sure you use toasted sesame oil for the best flavor.
• Garlic and ginger: I grate both directly into the dressing so there aren’t any large pieces.
• Furikake: This Japanese seasoning usually contains sesame seeds, seaweed and salt. Check the label if you need it to be gluten-free.
• Chili crisp and crispy onions: Optional, but very good if you want extra heat and crunch.

How to Make Spicy Crab Salad

Top Tip

Cucumbers release water after they’re sliced, and salt speeds that up. For the best texture, keep the dressing separate until shortly before serving.

If your cucumbers seem especially watery, spread the slices over paper towels and blot them dry before assembling the salad. This keeps the dressing creamy instead of turning it into cucumber soup.

Substitutions

• Lump crab meat: Jumbo lump crab is great if you want larger pieces, while claw meat is less expensive and has a stronger crab flavor. Imitation crab works, but the result will be closer to kani salad.
• English cucumbers: Persian cucumbers are my first substitute because they’re also crisp and have very few seeds. Use about five or six, depending on their size.
• Kewpie mayo: Regular mayonnaise or light mayonnaise both work. Kewpie is richer and has a slightly different flavor, but this is not a dealbreaker.
• Greek yogurt: Sour cream is the closest substitute. The dressing will be a little richer and less tangy.
• Soy sauce: Use tamari for a gluten-free option or coconut aminos if you want something slightly sweeter and less salty.
• Cilantro: If you hate cilantro, leave it out or replace it with chopped chives. I’m not going to tell you parsley tastes the same because it doesn’t.
• Honey: Maple syrup or a small pinch of sugar will work.
• Furikake: Use toasted sesame seeds plus a little crumbled nori.

Spicy Crab Salad Variations

• Make it extra spicy: Add more sriracha to the dressing, keep the jalapeño seeds or finish the salad with extra chili crisp.
• Turn it into a rice bowl: Serve it over sushi rice or jasmine rice with edamame, shredded carrots and nori.
• Make lettuce cups: Spoon the salad into butter lettuce leaves and top with sesame seeds and scallions.
• Add mango: Diced mango adds sweetness that works really well with sriracha, lime and crab.
• Give it more crunch: Add shredded carrots, radishes or crispy wonton strips immediately before serving.
• Make cucumber bites: Cut a cucumber into thick rounds and spoon a small amount of crab salad onto each one for an easy appetizer.

What to Serve with Spicy Crab Salad

For a light lunch, I usually eat this exactly as it is. If you want a more substantial meal, serve it with jasmine rice, sushi rice or a chilled noodle salad.

It also works with:

• Lettuce cups
• Crispy wonton chips
• Seaweed snacks
• Edamame
• Steamed rice
• Avocado toast
• A simple miso soup

Make Ahead

You can make the dressing up to three days ahead and keep it in an airtight container in the refrigerator.

The cucumbers, scallions, cilantro and jalapeño can be prepared several hours ahead, but store them separately from the dressing. Dice the avocado and assemble the salad shortly before serving.

I would add the crab no more than a few hours before serving. Keep the furikake, crispy onions and chili crisp separate until the end.

How to Store Crab and Cucumber Salad

Store leftover salad in an airtight container in the refrigerator and eat it within two days. The cucumber will release some water and the avocado may darken, so the texture is best on the day it’s made.

This salad doesn’t freeze well. Cucumbers and avocado both become soft and watery after thawing, and creamy dressings can separate.

Serve leftovers cold. There is no reason to reheat this one.

Frequently Asked Questions About Spicy Crab Salad

Can I use canned crab meat?

Yes. Drain it very well, check it for shells and gently pat it dry before adding it to the salad. Refrigerated lump crab meat usually has a better texture, but canned crab works when you need a convenient option.

Can I use imitation crab?

Absolutely. Shred or slice it before adding it to the vegetables. Imitation crab is sweeter and firmer than lump crab, so the finished salad will taste more like spicy kani salad.

Is this spicy crab salad very hot?

It has a moderate kick from one tablespoon of sriracha. For a milder version, start with one or two teaspoons and skip the jalapeño and chili crisp. If you love heat, add all three. Obviously.

Can I make it gluten-free?

Yes. Use certified gluten-free tamari instead of soy sauce and check the labels on the Kewpie mayo, sriracha, furikake, chili crisp and crispy onions.

How do I keep the salad from getting watery?

Use English or Persian cucumbers, blot the slices dry and wait to add the dressing until shortly before serving. Keep the salad cold and don’t salt the cucumbers in advance.

Can I make this ahead for meal prep?

You can prepare the components ahead, but don’t fully assemble all four servings. Store the dressing, vegetables, crab, avocado and crunchy toppings separately. Combine them when you’re ready to eat.
