Keto Spicy Salmon Cucumber Bites

We’ve always had a soft spot for sushi. There’s something about the creamy, spicy, salty combination of fresh fish and that perfect bite of rice that just calls to us. But when we shifted into the keto lifestyle, sushi night became one of those things we thought we had to say goodbye to. That is—until these spicy salmon cucumber bites came along and completely changed the game.

This dish came from one of those late-night kitchen brainstorms. We were craving something fresh but indulgent, something that could scratch that sushi itch without throwing our macros out the window. And then we remembered how versatile cucumber is—crisp, clean, and just the right amount of crunch. We scooped a little spicy salmon mix onto some thick cucumber slices, took a bite, and immediately knew we were onto something.

Now, this recipe has become a staple in our house. Whether we’re throwing together a quick lunch, prepping appetizers for friends, or just wanting to feel a little fancy on a Tuesday night, these bites are always a hit. They come together in under 15 minutes, they look beautiful on a plate, and they’re packed with flavor and healthy fats. It’s one of those keto recipes that feels like a treat—but actually helps us stay right on track.

These spicy salmon cucumber bites are a celebration of everything we love about sushi, with none of the carb count. Once you try them, we promise—you’ll never look at a cucumber the same way again.

1/2x 1x 2x 3x

• 6 oz sushi-grade salmon, finely diced

• 2 tbsp mayonnaise (preferably avocado oil-based)

• 1 tsp sriracha (adjust to taste)

• ¹⁄₂ tsp toasted sesame oil

• ¹⁄₂ tsp rice vinegar (no sugar added)

• ¹⁄₄ tsp sea salt

Instructions

1. Prep the salmon: Make sure your salmon is sushi-grade and has been kept cold. Dice it finely into small cubes so it mixes well and is easy to scoop.

3. Combine: Add the diced salmon and avocado (if using) to the spicy mayo mixture. Mix gently until well-coated.
4. Prepare the cucumber base: Slice the cucumber into even 1/4-inch thick rounds. Lay them out on a serving plate.
5. Assemble the bites: Scoop about 1 tablespoon of the spicy salmon mixture onto each cucumber slice.
6. Garnish: Top with black sesame seeds and chopped green onions for that extra sushi-style flair.
7. Serve immediately: These are best served fresh and cold.
