Ingredients

(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)

Cucumber

A long, firm cucumber serves as the base of the entire recipe. Its natural crunch mimics the bite of sushi while providing structure to the roll. I prefer English cucumbers because they slice cleanly and have fewer seeds.

Cream Cheese

Cream cheese adds richness and stabilizes the filling. It acts almost like the rice layer in regular sushi, binding everything together. You can soften it slightly before spreading for smoother application.

Smoked Salmon

Smoked salmon brings savoury depth and a classic sushi-inspired flavour profile. Its buttery texture works beautifully against the fresh cucumber. You may substitute with cooked shrimp or canned tuna if needed.

Avocado

Avocado adds creaminess and healthy fats essential in keto cooking. When sliced thinly, it adds body without overpowering the other ingredients.

Sesame Seeds

These provide a subtle nutty flavour and a touch of visual appeal. They give the rolls a familiar sushi aesthetic and a barely-there crunch.

Soy Sauce or Coconut Aminos

A dipping sauce is vital for rounding out the dish. Soy sauce adds saltiness, while coconut aminos are an excellent low-carb, gluten-free alternative with a touch of sweetness.

Nori Sheets (Optional)

Although not required, nori sheets can bring a traditional sushi flavour. They wrap easily around the cucumber roll and help hold everything in place.

Directions

Begin by thoroughly washing and drying the cucumber. Trim both ends and use a sharp vegetable peeler to remove alternating strips of skin, giving the roll some additional grip. Slice the cucumber lengthwise and carefully hollow out the centre with a small spoon, ensuring the walls remain thick enough to hold the filling. Pat the interior dry to prevent excess moisture.

In a small bowl, mix the softened cream cheese until smooth and spreadable. Coat the inside of each cucumber half with a thin, even layer. This will help your remaining ingredients adhere. Arrange slices of smoked salmon along the cream cheese, followed by thin strips of avocado. Press gently to remove any gaps so the roll stays compact.

Place the other half of the cucumber on top to reassemble the shape. Wrap tightly with plastic wrap and refrigerate for at least fifteen minutes; this step firms the filling and makes clean slicing easier. Once chilled, unwrap and use a sharp knife to cut the cucumber into bite-sized pieces, wiping the blade between each cut to maintain neat edges. Sprinkle sesame seeds on top and serve with soy sauce or coconut aminos for dipping.

Servings and timing

This recipe yields approximately 2 servings. Preparation time is about 15 minutes, followed by 15 minutes of chilling. No cooking time is required, making it ideal for quick meals or snacks.

Storage/reheating

Cucumber sushi is best eaten fresh, as cucumbers release moisture over time. However, you may store leftovers in an airtight container in the refrigerator for up to 24 hours. Reheating is not applicable for this recipe, as the ingredients are enjoyed cold. For best results, pat the pieces dry before serving if any moisture accumulates.

Variations and Customizations

Spicy Tuna Version

Mix canned tuna with mayonnaise and a small amount of hot sauce to create a creamy, spicy filling.

Chicken Salad Filling

For added protein, fill the cucumber with a simple chicken salad made from shredded chicken and a light keto-friendly dressing.

Vegetarian Roll

Replace salmon with thinly sliced bell peppers, carrots, or zucchini for a colourful plant-based option.

Herb-Infused Cream Cheese

Blend fresh dill, chives, or parsley into your cream cheese for a fragrant, savoury twist.

Crunchy Keto Roll

Add finely chopped nuts such as almonds or walnuts inside the roll to introduce a crunchy texture.

Nori-Wrapped Version

Wrap the cucumber roll in a sheet of nori for added umami and a more traditional sushi flavour.

Pickled Vegetable Kick

Add thin pieces of pickled radish or ginger to brighten and balance the richness of the cream cheese.

Pesto Layer

Spread a very thin line of pesto inside the roll for an unexpected burst of flavour.

Wasabi Cream Cheese

Blend a small amount of wasabi into the cream cheese for heat reminiscent of classic sushi.

Crab and Cucumber Roll

Substitute salmon with lump crab meat for a sweeter, more delicate filling.
