Ingredients for bj's ahi tuna salad
Fresh, crispy tuna meets cool cucumber—just four key ingredients transform into restaurant-style perfection.
| Ingredient | Amount | Notes |
|---|---|---|
| Ahi Tuna Steak 🐟 | 1 lb | Sushi-grade, center-cut preferred |
| Persian Cucumber 🥒 | 1 whole | Seeded, thinly sliced lengthwise |
| Ripe Avocado 🥑 | 1 whole | Pitted, peeled, cubed |
| Extra-Firm Tofu 🍫 | ½ lb | Pressed, cubed for texture |
| Fresh Cilantro 🌿 | ¼ cup | Chopped, stems removed |
| Red Bell Pepper 🌶️ | ¼ cup | Diced, seeds removed |
| Lime 🍋 | 1 whole | Juiced, zest optional |
| Sesame Oil 🫒 | 1 tbsp | Toasted, for aroma |
| Soy Sauce 🍶 | 2 tbsp | Low-sodium preferred |
| Honey 🍯 | 1 tbsp | Raw preferred for flavor |
| Rice Vinegar 💧 | 1 tbsp | Seasoned for balance |
| Toasted Sesame Seeds 🌾 | 1 tsp | For garnish |
| Avocado Oil 🫒 | 2 tbsp | High smoke point for searing |
| Diamond Crystal Kosher Salt 🧂 | ½ tsp | For seasoning |
| Freshly Ground Black Pepper 🌶️ | ¼ tsp | Coarsely ground |
The tuna is everything here. Sushi-grade ahi from the seafood counter—ask for center-cut, it's leaner and holds shape better when seared. Whole Foods or local fishmongers usually carry the best quality, but the grocery store seafood section works too if you grab it fresh. That crispy edge? It's all about the avocado oil—high smoke point means no burning, just perfect browning. Don't skip pressing the tofu either; it adds that satisfying bite that balances the tender tuna. I like mine from Trader Joe's, but any extra-firm will do if you press it for 15 minutes first.
No sesame oil? Toasted peanut oil works in a pinch, though it'll taste different. Short on cucumber? English cucumber or even zucchini can stretch it out—just slice them extra thin. The dressing is where you can get creative: swap honey for agave or maple syrup, soy sauce for tamari or coconut aminos. Want more umami? Add a dash of fish sauce or a splash of mirin. The avocado's ripeness matters too—if it's too firm, let it sit at room temp for 30 minutes before cubing. And yes, you can prep the cucumber and avocado base ahead, but hold off on mixing until serving to keep it crisp.
This keeps beautifully for 2 days in the fridge if you store the tuna and dressing separately. The cucumber base stays fresh for 3 days if you keep the avocado separate until serving. For make-ahead parties, prep everything except the seared tuna—assemble just before serving so the tuna stays crispy. The dressing? It'll last 1 week in an airtight jar, but honestly, it disappears faster than that. Garnish with sesame seeds right before serving—trust me, it makes all the difference.

Step-by-step instructions for BJ's ahi tuna salad recipe
Here's how to create crispy tuna bites with a refreshing cucumber base—simple, bold flavors that shine.
Prepare the Crispy Tuna Bites
Pat the 1 lb Ahi Tuna Steak completely dry with paper towels—this is non-negotiable for crispy results. Cut into 1-inch cubes and place them in a bowl. In a small separate bowl, whisk together 2 tbsp Soy Sauce, 1 tbsp Honey, 1 tbsp Rice Vinegar, 0.5 tsp Diamond Crystal Kosher Salt, and 0.25 tsp Freshly Ground Black Pepper. Pour this marinade over the tuna and toss gently to coat evenly.
Heat 2 tbsp Avocado Oil in a large skillet over medium-high heat until shimmering. Add the tuna cubes in a single layer, leaving space between them. Cook undisturbed for 2-3 minutes per side until the edges develop a deep golden-brown crust and the interior reaches 125°F—this ensures perfect doneness without overcooking. The tuna should look crispy on the outside while remaining tender inside. Transfer to a plate and set aside.
Create the Cool Cucumber Base
Using a sharp knife, carefully slice the 1 whole Persian Cucumber lengthwise into thin strips, removing the seeds as you go. Place the cucumber slices in a large mixing bowl and gently toss with 1 tbsp Sesame Oil, 1 tbsp Rice Vinegar, and a pinch of Diamond Crystal Kosher Salt. Let this sit for 5 minutes to allow the flavors to meld—this step is what gives the salad its refreshing, crisp texture.
While the cucumber marinates, dice the 0.25 cup Red Bell Pepper into small, even pieces and finely chop the 0.25 cup Fresh Cilantro, removing any tough stems. Add these to the cucumber mixture and toss lightly. The goal here is to keep everything bright and fresh—overmixing will bruise the cucumber and make it soggy. Squeeze the juice from the 1 whole Lime (about 2 tablespoons) over the mixture and stir gently to combine.
Add Creamy Avocado and Tofu Texture
Cube the 1 whole Ripe Avocado into ½-inch pieces and add them to the cucumber mixture. Gently fold everything together—avoid crushing the avocado, as this will release too much liquid and dilute the flavors. Press the 0.5 lb Extra-Firm Tofu between two paper towels for 10 minutes to remove excess moisture, then cut it into small cubes. Add these to the bowl and toss one last time, ensuring all components are evenly distributed.
Here's the thing—this is where the magic happens. The crispy tuna bites need a contrast of textures, so don't skip the tofu. It adds a subtle protein element that balances the richness of the avocado and the brightness of the cucumber. Taste the mixture now and adjust seasoning if needed—you might want to add a touch more lime juice or a pinch of salt to enhance the flavors.
Assemble and Garnish for Serving
Divide the cucumber-avocado-tofu mixture evenly among 4 serving bowls. Arrange the crispy tuna bites on top of each serving, fanning them out slightly for presentation. Drizzle each portion with a light stream of 1 tbsp Sesame Oil and sprinkle generously with 1 tsp Toasted Sesame Seeds. The seeds add a nutty crunch that cuts through the creaminess of the avocado and the crispness of the cucumber.
Serve immediately while the tuna is still crispy and the cucumber holds its shape. If you're serving this at a gathering, I recommend assembling the bowls just before guests arrive—this salad doesn't hold up well when made ahead due to the avocado and cucumber. Pair with warm rice or fresh baguette slices to soak up all the delicious juices. Every bite should deliver that perfect contrast: crispy tuna, cool cucumber, creamy avocado, and a hint of spice from the seeds.
Pro Tips For Making Bj'S Ahi Tuna Salad
- Sear Tuna Just 2 Minutes: High heat, cast-iron pan—no more, no less. Ahi tuna’s delicate texture turns to rubber if you overcook, but 2 minutes per side (medium-high) gives that perfect medium-rare finish. Flip only once, and resist the urge to poke it like a chicken breast.
- Cube Tofu Dry First: Pat that extra-firm tofu bone dry with paper towels before pressing or cubing. Wet tofu steams instead of searing, and this salad needs crisp edges—not soggy ones. I learned this the hard way after a batch turned out tasting like a sad, waterlogged sponge.
- Peel Cucumber Wrong: Skip the peeler—use a paring knife to slice off the top and bottom first, then shave the sides in one long strip. Persian cucumbers have edible skin, but the seeds near the ends are bitter. This keeps the texture clean while saving you from peeling 90% of the cucumber.
- Mash Avocado Last: Hold off on mashing the avocado until right before serving. The salad’s acidity (lime, maybe vinegar) makes it turn brown faster than you’d think. Toss it in at the end—even if it’s messy, the flavor’s worth the effort. (Yes, I’ve ruined a whole bowl waiting too long.)
Flavor customization for bj's ahi tuna salad
Spicy Kick
Want to turn up the heat? Add 1 tsp of Sriracha or ½ tsp of gochujang to the tuna marinade for a subtle spicy edge. For extra heat, toss in ½ tsp of finely chopped red chili flakes with the cucumber base.
I love balancing the spice with a drizzle of 1 tsp of honey on top to mellow the burn while keeping the flavor dynamic. 🌶️
Citrus Twist
Brighten the dish with a zesty citrus punch by adding 1 tbsp of orange zest to the cucumber base or swapping lime for grapefruit juice in the dressing. The bitterness of grapefruit cuts through the richness of the avocado beautifully.
For a tropical vibe, top with ¼ cup of diced mango or kiwi slices just before serving. 🍊
Umami Boost
Elevate the dish with extra umami depth by adding 1 tsp of fish sauce or 1 tbsp of miso paste to the dressing. For a smoky touch, sprinkle ½ tsp of smoked paprika over the tuna bites before searing.
If you're feeling adventurous, add 1 tbsp of finely chopped pickled ginger to the cucumber base for a tangy, briny contrast. 💡
Herb Infusion
Swap out cilantro for fresh mint or basil to give the salad a different herbal profile. Mint adds a refreshing coolness, while basil brings a slightly sweet, aromatic note. For a Mediterranean twist, toss in ¼ cup of chopped kalamata olives with the cucumber base. 🌿
Crunchy Additions
Add texture with ½ cup of toasted almonds or crushed wasabi peas for a spicy crunch. For a nutty contrast, sprinkle 1 tbsp of crushed peanuts over the top. If you want something lighter, try thinly sliced radishes or shredded carrots mixed into the cucumber base. 🥜
Sweet-Savory Balance
Enhance the dressing with 1 tsp of maple syrup or agave nectar for a sweeter profile. For a caramelized touch, lightly toast 1 tbsp of coconut flakes and sprinkle them over the top.
A drizzle of reduced balsamic glaze adds a tangy sweetness that pairs perfectly with the crispy tuna. 🍯

Frequently asked questions
Can I use canned tuna instead of fresh ahi tuna?
The recipe is designed specifically for fresh ahi tuna to achieve that perfect crispy texture and delicate flavor. Canned tuna won't give you the same satisfying crunch or fresh taste. If you absolutely must use canned, opt for high-quality sushi-grade canned ahi and pat it very dry before cooking, but expect a different texture.
How do I prevent the avocado from turning brown?
Toss the avocado cubes with a little lime juice immediately after cutting and keep them submerged in cold water until ready to use. The acidity in the lime slows oxidation, and the cold water helps maintain freshness. For extra protection, sprinkle with a pinch of salt or cover tightly with plastic wrap.
What's the best way to store leftovers?
Store the crispy tuna bites and cucumber base separately in airtight containers. The tuna will stay crispy for up to 2 days in the fridge, while the cucumber base keeps well for 3 days. Reheat the tuna gently in a dry skillet for 30 seconds before reassembling—just enough to restore crispiness without overcooking.
Can I make this salad ahead of time?
Prep the cucumber base and dressing up to 24 hours ahead, but hold off on adding the avocado until serving. The tuna should be seared fresh and added just before eating to maintain its crispy texture. If you're hosting, assemble everything except the tuna and keep it chilled until the last minute.
What's the secret to getting perfectly crispy tuna?
Three things: dry tuna (pat it thoroughly), high heat (medium-high or higher), and minimal movement while cooking. The tuna should sizzle immediately when it hits the pan. Use a meat thermometer to check for 125°F internal temp—this ensures tender centers with crispy edges.
