Easy Tuna Avocado Cucumber Sushi Rolls at Home

Homemade sushi sounds like a meal that requires a culinary degree, expensive fish, and far more patience than you have on a weeknight. This makes easy homemade tuna sushi rolls seem unattainable for many cooks.

Luckily, it’s not as challenging as you may think.

These easy homemade tuna sushi rolls are one of my favorite ways to make sushi at home without dealing with raw fish or a long list of ingredients. They’re made with seasoned sushi rice, a tuna packet, creamy avocado, crisp cucumber, and nori, then topped with Everything But the Bagel seasoning for a little extra flavor and crunch.

My favorite version uses jalapeño-flavored tuna, which adds just enough heat without requiring another ingredient or sauce. You can use another flavored tuna packet, or stick with plain tuna, or change up the fillings depending on what you have. These easy homemade tuna sushi rolls can be customized to your pantry.

Once the rice is cooked, there is no more actual cooking involved. Just assemble, roll, slice, and eat.

Why Tuna Packets Are My Favorite Shortcut for Homemade Sushi

You can absolutely make tuna sushi with canned tuna, but I prefer tuna packets because they tend to be less watery and messy.

There’s no can to drain, and the tuna generally contains less excess liquid. That’s particularly helpful with sushi because too much moisture in your filling can make your roll soggy and harder to keep together.

They’re also ridiculously convenient. Tear open the packet, add the tuna, and you’re ready to roll.

I especially love using jalapeño-flavored tuna because the seasoning is already built in. It gives the sushi a little kick without having to mix up a spicy tuna filling.

If jalapeño isn’t your thing, experiment with other flavors or use plain tuna. Plain tuna also gives you a blank canvas for whatever sauces and toppings you’re craving.

What You’ll Need for Easy Tuna Sushi Rolls

One of the best things about this recipe is how short the ingredient list is.

You’ll need:

• Sushi rice
• Nori sheets
• Tuna packets
• Avocado
• Cucumber
• Everything But the Bagel seasoning (optional)
• Your favorite sauce for dipping or drizzling (optional)

Your exact quantities and instructions are in the recipe card below, but there are a few things worth knowing before you start.

What I Use to Make Homemade Sushi Easier

You don’t need a ton of special equipment to make sushi at home, but a few basics make the whole process easier, cleaner, and a lot more enjoyable. These are the tools and extras I usually reach for.

Sushi Mat & Paddle

You can roll sushi with plastic wrap in a pinch, but a bamboo sushi mat makes it much easier to get a tight, even roll without everything sliding around. If you plan on making sushi more than once or twice, it’s worth having one.

Nori sheets

I order my nori sheets from Amazon so I can keep a pack in the pantry whenever a sushi craving hits. They’re the classic seaweed sheets that hold everything together and add that slightly salty, savory flavor that makes homemade rolls actually taste like sushi.

Or if you’d prefer to mix it all in a bowl and scoop it into bite-sized seaweed sheets, you’ll want seaweed snacks. The teriyaki is my favorite flavor, but choose your favorite! (As a bonus, they’re all gluten free!)

Seaweed snacks →

Chopsticks

Not technically necessary, obviously, but they make homemade sushi feel a little more fun. They’re also handy for picking up individual pieces without squishing them.

Wasabi

A little wasabi goes a long way. Add a small amount to your dipping sauce or dab just a touch onto each piece if you like that sharp, spicy kick.

Pickled Ginger

Pickled ginger adds a bright, slightly sweet and tangy contrast between bites. I like serving a small pile alongside the rolls so you can grab a piece whenever you want something fresh and punchy.

Soy Sauce or Coconut Aminos

Either works as a simple dipping sauce. Soy sauce gives you that classic salty sushi flavor, while coconut aminos are a slightly sweeter alternative. Use whichever one fits your taste and dietary needs.

Rice vinegar

You don’t have to use this to make your rice if you’d prefer not to, but this is what gives sushi rice that subtle tangy-sweet flavor that makes it taste like sushi rice instead of just plain rice. A little goes a long way, and it’s an easy pantry staple to keep around if you plan on making sushi at home regularly.

If you choose to make this version of sushi rice, cook 1 cup of sushi rice according to the package directions, then gently fold in 2 tablespoons rice vinegar, 1 tablespoon sugar, and ½ teaspoon salt while the rice is still warm and let it cool to room temperature before rolling.

Start With the Right Rice

If you’re going to put effort into one part of homemade sushi, make the rice.

Sushi rice is a short-grain rice that becomes slightly sticky when cooked, which is exactly what you need to keep your rolls together. Long-grain varieties won’t behave quite the same way.

Once your rice is cooked and seasoned, give it time to cool before assembling your sushi. Putting piping-hot rice directly onto your nori isn’t going to do your roll any favors.

And when you’re spreading the rice, less is more. You don’t need a massive layer.

Over-stuffing is one of the easiest ways to turn your beautiful homemade sushi roll into a pile of ingredients that vaguely remembers once being sushi.

Keep the Fillings Simple

There’s a reason tuna, avocado, and cucumber work so well together.

The tuna adds protein and savory flavor, avocado gives the roll its creamy texture, and cucumber adds freshness and crunch.

That’s really all you need.

Cut the cucumber and avocado into relatively thin strips so they’re easy to arrange across the nori. Then add your tuna in a line alongside them.

You want enough filling to get some of everything in each bite without putting so much inside that you can’t close the roll.

How to Roll Sushi at Home Without Making a Complete Mess

Your first homemade sushi roll may not look like it came from a restaurant.

That’s fine. We’re eating it, not submitting it for inspection.

A few tricks make rolling much easier:

Keep your hands damp. Sushi rice is sticky as hell. Keep a small bowl of water nearby and wet your fingertips before handling it.

Don’t pile on the rice. Spread a relatively thin, even layer rather than creating a rice mattress.

Don’t overfill the center. This is probably the biggest mistake. A smaller amount of filling makes a much tighter roll.

Roll firmly but gently. You want enough pressure to keep everything together without smashing the avocado out the sides.

Use a sharp knife. A dull knife will squash the roll instead of slicing cleanly through it.

Wet your knife between cuts. This helps prevent sticky rice from building up on the blade.

And if one roll comes out looking a little wonky? Congratulations, you’ve made homemade sushi.

Everything But the Bagel Seasoning > Plain Sesame Seeds

Traditional sesame seeds are great, but I usually reach for Everything But the Bagel seasoning instead.

You still get the sesame seeds, but you also get all the extra savory flavor from the rest of the seasoning blend. Sprinkle it over the finished rolls or add a little to the rice side of the roll before assembling.

It’s a tiny change, but it makes a very simple tuna, avocado, and cucumber roll much more interesting.

If you prefer traditional sushi, you can absolutely stick with sesame seeds. Black and white sesame seeds also look beautiful sprinkled over the finished rolls.

Make Them Spicy

Using jalapeño tuna is my favorite way to add heat, but you have plenty of options.

For an even spicier roll, add a drizzle of spicy mayo or sriracha. Fresh jalapeño slices can add both heat and crunch, while chili crisp gives you a completely different texture and flavor.

Not into spicy food?

Use plain tuna and keep everything simple. You can serve the rolls with soy sauce or tamari, or add a little mayo to the tuna before rolling if you prefer a creamier filling.

Easy Add-Ins and Swaps

Once you’ve gotten comfortable making the basic roll, this recipe is ridiculously easy to change.

Try adding cream cheese for an extra-creamy roll, green onion for more bite, shredded carrots for crunch, or mango if you like a sweet-and-savory combination.

You can also swap the tuna for cooked shrimp, crab, smoked salmon, or another protein you enjoy.

And don’t forget about toppings. Try spicy mayo, chili crisp, sliced green onion, avocado, sesame seeds, or your favorite sushi sauce.

You can essentially use the basic recipe as a template and make a different version every time.

Don’t Want to Roll It? Make a Tuna Sushi Bowl

There are days when rolling individual pieces of sushi sounds fun.

And there are days when absolutely the fuck not.

Luckily, every ingredient in this recipe works just as well in a bowl.

Add your sushi rice to a bowl and top it with tuna, chopped avocado, cucumber, strips or pieces of nori, and Everything But the Bagel seasoning. Finish it with your favorite sauce.

It’s also a great option if you have leftover ingredients that aren’t quite enough to make another full roll.

What to Serve With Tuna Sushi Rolls

These rolls can easily be a meal on their own, but they’re also easy to turn into a bigger spread.

I like simple sides that don’t require much additional work: edamame, cucumber salad, seaweed salad, miso soup, pickled ginger, or extra sliced vegetables all work well.

You can also put out a few sauces and let everyone dip or drizzle their own.

A Note for Gluten-Free Sushi

The basic ingredients in these tuna avocado cucumber rolls can be easy to adapt for a gluten-free diet, but check every packaged ingredient individually.

Pay particular attention to your tuna packet and seasonings, since flavored products can contain additional ingredients. Traditional soy sauce also commonly contains wheat, so choose a gluten-free soy sauce or tamari if needed.

The same goes for any spicy mayo, eel-style sauce, chili crisp, or other condiments you add.

My Go-To Easy Homemade Sushi

The thing I love most about these easy homemade tuna sushi rolls is that they hit that sweet spot between I made something and I really didn’t have to do that much.

The tuna packet eliminates the raw-fish prep and mess. Avocado makes everything creamy. Cucumber gives you crunch. Jalapeño tuna adds a little heat. And Everything But the Bagel seasoning gives the whole thing more flavor without requiring another step.

Once you’ve figured out the rice and rolling technique, homemade sushi becomes less of a special-occasion project and more of an easy meal you can throw together whenever the craving hits.

And if the roll falls apart?

Put it in a bowl and pretend that was the plan all along.

Frequently Asked Questions About Homemade Tuna Sushi

Can I use canned tuna instead of a tuna packet?

Absolutely. I prefer tuna packets because they contain less excess liquid and don’t require draining, which makes them a little less messy for sushi. If you’re using canned tuna, drain it really well before adding it to your roll.

Do I need a sushi mat to make sushi?

Nope! You can use plastic wrap if you don’t have a sushi mat. However, I find a bamboo sushi mat much easier for creating a tight, evenly shaped roll, especially when you’re first learning.

Which side of the nori does the rice go on?

Place the nori with the shiny, smooth side facing down and the rough side facing up. Spread your rice over the rough side so it sticks more easily.

Why does my sushi fall apart when I cut it?

Usually it’s from overfilling the roll, rolling it too loosely, or using a dull knife. Keep your fillings relatively thin, apply gentle pressure as you roll, and use a sharp knife that’s been lightly dampened before slicing.

Can I make this recipe without rolling sushi?

Yes! Put the sushi rice in a bowl and add the tuna, avocado, cucumber, and your favorite sauce. You can either mix pieces of nori or scoop them onto seaweed snacks.

How long does homemade tuna sushi last?

It’s best eaten fresh, particularly because the avocado can brown and refrigerated sushi rice changes texture. If you do have leftovers, store them covered in the refrigerator and eat them promptly.
