These are straightforward maki rolls filled with ripe avocado and crisp cucumber, wrapped in seasoned sushi rice and nori. The ingredient list is short, the flavors are clean, and the whole thing comes together in about 45 minutes once your rice is ready. If you’ve never made sushi at home before, this is the right place to start.
What makes this version work
Two things matter more than anything else here. First, the rice seasoning ratio — rice vinegar, organic cane sugar, and sea salt need to be fully dissolved and folded in while the rice is still warm, not hot and not cold. Warm rice absorbs the mixture evenly; cold rice won’t, and you’ll end up with clumps that taste flat. Second, the rolling pressure. A lot of first-timers either roll too loosely, which causes the whole thing to fall apart when sliced, or squeeze so hard the filling squirts out. Firm, even pressure across the full length of the mat — not a death grip at the ends — keeps the roll tight and the cross-section clean. Get those two steps right and everything else follows.
Keeping and reheating
Sushi rice hardens in the fridge, so these rolls are best eaten the day they’re made, ideally within a few hours of rolling. If you need to store them, wrap each roll tightly in plastic wrap before slicing and refrigerate for up to 12 hours — slicing first exposes the rice to air and speeds up drying. Do not freeze finished rolls; the rice turns grainy and the cucumber goes watery. If you have leftover seasoned rice on its own, it keeps in an airtight container at room temperature for up to 4 hours or refrigerated overnight — let it sit out for 20 minutes before using it again, since cold rice won’t roll well. There is no reheating step for finished rolls; serve them at room temperature.
Troubleshooting
- Nori tears when you roll it: This usually means the nori got damp from sitting out too long after you spread the rice. Work quickly — once the rice goes on, roll within about 60 seconds. If your kitchen is humid, keep unused nori sheets in their sealed package until the moment you need them.
- Rice sticks to everything except the nori: Your hands or the mat are dry. Wet your hands with plain water before handling rice, and lightly dampen the mat with a damp cloth. Don’t soak either — just enough moisture to prevent sticking.
- The roll unravels after slicing: The seam wasn’t sealed. After rolling, rest the finished roll seam-side down on the mat for 30 seconds before you pick it up. The moisture from the rice will seal the nori edge on its own.
- Avocado turns brown before serving: Skip the garnish — not worth the extra dish — and instead focus on cutting the avocado last, right before assembly. A very light brush of lemon or lime juice on the cut surface slows oxidation if you’re working ahead.
- Slices compress or squash when cutting: The knife isn’t wet enough or isn’t sharp enough. Wipe the blade with a damp cloth between every single cut, not every few cuts. A dull knife drags the nori and crushes the roll; if yours isn’t sharp, use a serrated bread knife as a backup — it tears slightly but compresses less.
Cucumber and Avocado Sushi Rolls
Equipment
- Sushi mat (makisu)
- Sharp knife
- Rice paddle or silicone spatula
- Medium pot with lid
- Cutting board
Ingredients
Sushi Rice
- 1 cup sushi rice short-grain Japanese rice, rinsed 3-4 times until water runs clear
- 1 ¼ cups water filtered
- 2 tablespoons rice vinegar unseasoned, high-quality
- 1 ½ teaspoons organic cane sugar
- ½ teaspoon sea salt
Filling & Assembly
- 1 whole ripe avocado peeled, pitted, and sliced into thin strips
- 1 medium English cucumber cut into thin matchsticks
- 4 sheets nori seaweed raw or toasted
- 1 tablespoon toasted sesame seeds optional, for garnish
Instructions
- In a medium pot, combine the rinsed sushi rice and water. Bring to a boil, then reduce heat, cover, and simmer for 18–20 minutes until all the water is absorbed. Remove from heat and let it sit covered for 10 minutes.
- In a small bowl, whisk together the rice vinegar, sugar, and salt until dissolved. Fold this mixture gently into the slightly cooled rice using a rice paddle. Let the seasoned rice cool to room temperature before assembling.
- Place one sheet of nori on a bamboo sushi mat, shiny side down. Wet your hands and spread a thin, even layer of rice over 3/4 of the sheet, leaving the top edge exposed to seal the roll.
- Align a few strips each of avocado and cucumber horizontally across the center of the rice-covered nori.
- Using the bamboo mat, roll the sheet tightly away from you, pressing firmly but gently. Wet the exposed nori edge to seal the roll. Repeat with remaining ingredients.
- Using a very sharp, wet knife, slice each roll into 6–8 pieces. Wipe the blade between cuts for clean slices.
- Sprinkle with toasted sesame seeds for added texture and flavor, if desired.
Notes
- For a twist, add pickled radish, shredded carrot, or vegan cream cheese inside the roll.
- You can prepare and season the rice up to a day in advance. Keep covered with a damp towel in the refrigerator and bring to room temperature before using.
- A serrated knife makes cleaner cuts if your chef’s knife isn’t sharp enough.

Common questions
Do I need a bamboo rolling mat, or can I use something else?
A bamboo mat makes rolling easier and more consistent, but a clean kitchen towel works as a substitute. Lay a sheet of plastic wrap over the towel first so the rice doesn’t stick to the fabric, then roll the same way you would with a mat.
What kind of rice do I actually need — can I use regular long-grain rice?
No — you need short-grain Japanese sushi rice specifically. Long-grain rice doesn’t have enough starch to stick together, so the roll will fall apart when you slice it. Look for bags labeled ‘sushi rice’ or ‘Japanese short-grain rice’ at most grocery stores.
My avocado isn’t ripe yet. Can I still make this today?
Not ideally — an underripe avocado is hard to slice cleanly and tastes bitter. To speed ripening, place the avocado in a paper bag with a banana at room temperature; it’s usually ready in 1 to 2 days.
What can I serve with these rolls instead of soy sauce if I’m avoiding soy?
Coconut aminos is the most straightforward swap — it’s slightly sweeter than soy sauce but works well as a dipping sauce. You can find it at most health food stores and many regular supermarkets.
Can I make the rice ahead of time the night before?
It’s not recommended — refrigerated sushi rice becomes hard and dry overnight and won’t roll properly even after resting at room temperature. Make the rice on the same day, up to 2 to 3 hours ahead, and store it covered at room temperature until you’re ready to roll.
