Ingredients:  

  • 2 cucumbers, halved lengthwise
  • 1 cup cooked and cooled sushi rice or leftover rice
  • 1 1/2 cups chopped cooked salmon (about one fillet)
  • 2 spring onions, chopped
  • 1 tbsp sriracha
  • 1/4 cup light mayonnaise
  • 2 tbsp black sesame seeds

Instructions: 

  • Cook the rice: Rinse 1 cup sushi rice under cold water to remove excess starch. Combine with 2 cups water in a pot. Bring to a boil, reduce heat, cover, and simmer 12 minutes. Remove from heat and let steam with the lid on 5 minutes. Spread the rice on a baking sheet to cool, or use leftover cooled rice.
  • Prepare cucumbers: Slice cucumbers lengthwise and scoop out the watery center with a spoon. Pat dry with paper towels so the rice won’t get soggy.
  • Make the filling: In a bowl, combine chopped cooked salmon, light mayo, sriracha, chopped spring onions, and black sesame seeds. Mix until evenly combined. Adjust spice to taste.
  • Assemble: Wet your hands and gently press cooled rice into each cucumber half without packing it too tight. Spoon the spicy salmon mixture on top. Garnish with extra green onion and sesame seeds. Serve chilled.

Enjoy!

Spicy Salmon Cucumber Boats: A Smart Way to Use Leftovers

We all have nights when a leftover salmon fillet or a cup of rice is sitting in the fridge. This recipe turns those ingredients into something fresh and snackable. Rather than reheating a boring plate, transform leftovers into crunchy, flavorful cucumber boats that feel like a deliberate, light meal.

The sticky texture of sushi rice works especially well here because it holds together inside the cucumber. If you don’t have sushi rice, cooled jasmine or basmati rice will work—just allow it to cool before using. Rinsing rice before cooking removes excess starch and prevents clumping, which helps achieve the right texture.

Let’s Talk Cucumber Boats: The Crunch Factor

Cucumber boats are quick to prepare: slice lengthwise, scoop out the watery center, and pat dry. They act as a crisp, edible vessel that contrasts perfectly with the creamy salmon filling.

English or Persian cucumbers are the best choices because of their thin skin and small seeds. If your cucumbers are slightly curved, they’ll still hold the filling well once assembled.

Spicy Salmon Cucumber Boats: Spicy, Creamy, and Packed with Protein

The filling is a mix of cooked salmon, light mayo, sriracha, chopped scallions, and black sesame seeds. It’s creamy, spicy, and protein-rich—great for a light lunch, appetizer, or snack.

No sriracha on hand? Sambal oelek or a dash of your favorite hot sauce are fine substitutes. For a lighter or tangier option, swap mayo for Greek yogurt.

Tips for Building the Perfect Cucumber Boat

Layering tips for the best bite:

  1. Wet your hands before handling rice to prevent sticking.
  2. Press the rice gently into each cucumber half—firm enough to hold, not compressed.
  3. Top with the spicy salmon mixture and finish with extra green onion and sesame seeds.

For an attractive garnish, cut green onions into 2-inch pieces, slice lengthwise into thin strips, and toss in cold water to curl them into ribbons.
