Ingredients for bj's brewhouse ahi tuna salad
Crispy sesame-crusted tuna meets vibrant cucumber and zesty dressing for a restaurant-quality dish at home.
| Ingredient | Amount | Notes |
|---|---|---|
| Ahi Tuna Steak 🐟 | 1 lb | Sushi-grade, 1-inch thick slices |
| Sesame Seeds 🥜 | ¼ cup | White or black, toasted |
| Japanese Mayonnaise 🥫 | ¼ cup | Kewpie preferred for authenticity |
| Wasabi Powder 🌶️ | 1 tsp | Adjust to taste for heat |
| English Cucumber 🥒 | 1 whole | Seedless, thinly sliced |
| Red Bell Pepper 🌶️ | 1 whole | Thinly sliced, seeds removed |
| Red Leaf Lettuce 🥬 | 4 cups | Butter or romaine preferred |
| Edible Flowers 🌸 | ¼ cup | Nasturtiums or pansies |
| Rice Vinegar 🍶 | 2 tbsp | Seasoned preferred for depth |
| Sesame Oil 🫒 | 1 tbsp | Toasted for aroma |
| Soy Sauce 🥫 | 1 tbsp | Low-sodium preferred |
| Honey 🍯 | 1 tsp | Substitute maple syrup if vegan |
| Vegetable Oil 🫒 | 2 tbsp | High smoke point for searing |
| Salt 🧂 | 1 tsp | Diamond Crystal preferred |
| Black Pepper 🌶️ | ½ tsp | Freshly cracked |
The ahi tuna is non-negotiable—sushi-grade quality ensures safety and tenderness. Look for bright red, firm flesh at specialty seafood markets like Whole Foods or Sprouts. If buying at a standard grocery store, Trader Joe's carries excellent pre-sliced options. For the sesame seeds, toasted white sesame adds subtle nuttiness, while black sesame offers a bolder flavor. The Kewpie Japanese mayonnaise is essential for that signature tang—don't substitute regular mayo. If unavailable, Hellmann's works in a pinch, though the flavor will differ slightly. For the wasabi, real wasabi powder (not the green paste) delivers authentic heat and aroma.
No Kewpie mayo? Hellmann's or Best Foods work, though the flavor will be milder. Substitute toasted sesame oil for the sesame seeds if needed, but the texture will differ. The English cucumber should be seedless—Persian cucumbers work if unavailable. For the dressing, rice vinegar is key; mirin can replace honey for a vegan version. The red bell pepper adds sweetness, but yellow or orange work equally well. If edible flowers aren't available, microgreens or chopped chives add freshness. The high-heat vegetable oil is critical for searing—avocado oil is another excellent choice.
Store the raw tuna on ice until ready to use—it spoils quickly. The dressing components (vinegar, soy sauce, honey) keep for 3 months in the fridge, while toasted sesame seeds stay fresh for 6 months in an airtight container. Assemble the salad last-minute to maintain crispness. The crispy tuna is best served immediately, but the vegetable components can be prepped 2 hours ahead. Garnish with extra sesame seeds and edible flowers just before serving for that restaurant touch. Leftovers? The tuna reheats poorly, but the vegetable mix holds for 1 day in the fridge.
Why You'll Love This Recipe
- No-Chop Magic: Honestly, the only prep is slicing the cucumber—thin, even strips—and toasting the sesame seeds. The ahi tuna comes pre-cooked (seared to perfection), so I just dice it, mix in the mayo and wasabi, and boom. Five minutes of actual work, and it’s ready to impress.
- Umami Bomb: That Japanese mayo? Rich, tangy, and just sweet enough to balance the wasabi’s kick. The crisp cucumber cuts through the richness while the toasted sesame seeds add this nutty crunch—every bite has layers, like a little flavor party in your mouth.
- Lunchbox Hero: Between us, this is my go-to for packed lunches or last-minute dinner guests. The salad keeps for days in the fridge (yes, even the tuna stays fresh), and I’ve served it on rice crackers, in lettuce cups, or straight from the bowl. Zero judgment.
- Budget Luxe Trick: Ahi tuna feels fancy, but buying it pre-seared and freezing portions makes it affordable. A little goes a long way—this recipe feeds four for under $20, and the leftovers? I turn them into poke bowls the next day. Frugal but feels like a splurge.
Step-by-step instructions for BJ's brewhouse ahi tuna salad
Here's how to recreate the signature crispy sesame crust and vibrant freshness from BJ's.
Create the Wasabi-Sesame Marinade
In a small bowl, whisk together the 0.25 cup Japanese mayonnaise, 1 tsp wasabi powder, 1 tbsp soy sauce, 1 tbsp sesame oil, 1 tsp honey, 1 tsp salt, and 0.5 tsp black pepper until smooth and fully combined. The wasabi will add a subtle kick that balances the richness of the tuna.
This marinade serves two purposes: it tenderizes the tuna slightly and creates that signature creamy texture you find in BJ's version. The honey helps mellow the wasabi's heat while adding a touch of sweetness that complements the umami flavors. Let the mixture sit at room temperature for 5 minutes to allow the flavors to meld.
Form the Sesame Crust and Sear the Tuna
Pat the 1 lb ahi tuna steak dry with paper towels and place it on a cutting board. Using a sharp knife, make shallow cuts about ¼ inch deep in a diamond pattern across the top surface of the tuna. This creates channels for the marinade to penetrate and helps the sesame seeds adhere better.
Spread the wasabi-sesame marinade evenly over the tuna, then press the 0.25 cup sesame seeds firmly onto the top surface. Use your fingers to work the seeds into the marinade, ensuring complete coverage. Heat 2 tbsp vegetable oil in a large skillet over medium-high heat until shimmering. Place the tuna, seed-side down, in the skillet and cook for 2-3 minutes until the crust is golden brown and crispy.
Prepare the Fresh Vegetable Components
While the tuna cooks, thinly slice the 1 whole English cucumber and 1 whole red bell pepper into ⅛-inch thick strips using a mandoline or sharp knife. Arrange the slices on a platter and lightly drizzle with 2 tbsp rice vinegar to enhance their natural sweetness. The acidity from the vinegar will brighten the flavors and prevent the vegetables from becoming soggy.
Gently separate the 4 cups red leaf lettuce into individual leaves and arrange them on a serving platter to form the salad base. Sprinkle the 0.25 cup edible flowers artistically over the lettuce leaves just before serving to add both visual appeal and a subtle floral note that complements the dish.
Assemble and Serve the Ahi Tuna Salad
Using a fish spatula, carefully flip the tuna to cook the other side for 1-2 minutes until it reaches medium-rare doneness (internal temperature 125-130°F). Let the tuna rest for 2 minutes before slicing it into ¼-inch thick pieces against the grain for maximum tenderness.
Arrange the sliced tuna over the prepared lettuce bed, then layer the cucumber and red bell pepper strips around the tuna. Drizzle any remaining marinade from the skillet over the salad and serve immediately. The contrast between the crispy sesame crust, cool cucumber, and vibrant bell pepper creates that signature BJ's experience with each bite.
Pro Tips For Making Bj'S Brewhouse Ahi Tuna Salad
- SEAR THE TUNA FAST: I learned this the hard way—ahi tuna turns rubbery if you overcook it. Hit a screaming-hot pan (no preheating needed) and sear for exactly 1 minute per side—no more. The outside should be charred, the center still pink. Let it rest 2 minutes before slicing, or it’ll fall apart when you mix it with the mayo.
- USE COLD CUCUMBER: Skip the warm cucumber—it gets soggy and dull. Peel the English cucumber, then slice it paper-thin and shock it in ice water for 10 minutes. Drain well before mixing into the salad. This keeps the crunch sharp and prevents the mayo from turning into a sad, watery mess.
- DON’T OVERMIX THE WASABI: A little goes a long way, and too much wasabi powder turns your salad into a nasal-clearing nightmare. Mix just 1 teaspoon into the mayo first, then taste. If you’re unsure, add a pinch more—but remember, you can’t take it out. The goal is a bright, subtle kick, not a sinus purge.
- TOSS SESAME SEEDS LAST: Sprinkle the sesame seeds on top right before serving, not when you’re assembling the bowl. They burn easily and lose their crunch if they sit in the mayo for more than a minute. Plus, they look way more professional when they’re fresh—like garnish, not forgotten garnish.
Flavor customization for this bj's brewhouse ahi tuna salad
Spice Level Control
The wasabi in the marinade adds a signature kick, but you can adjust it to your preference. For mild heat, reduce the wasabi to ½ tsp and add ½ tsp honey to balance.
If you love spice, increase to 1.5 tsp wasabi and add a pinch of red pepper flakes for extra depth. I find 1 tsp gives the perfect balance—just enough to awaken your palate without overwhelming the dish. 🌶️
Sweet-Tangy Balance
This salad thrives on the interplay between sweet and tangy flavors. For a more tangy profile, increase the rice vinegar to 3 tbsp and add ½ tsp lemon zest. For a sweeter touch, boost the honey to 1.5 tsp or substitute 1 tsp maple syrup.
I love the classic combo of 1 tbsp vinegar and 1 tsp honey—it mirrors BJ's signature flavor balance perfectly.
Crunchy Add-Ins
For extra texture, add ¼ cup toasted slivered almonds or crushed wasabi peas to the salad. If you prefer a nuttier crunch, sprinkle 2 tbsp chopped peanuts over the top.
I often add ½ tsp sesame seeds to the marinade for a double dose of toasty flavor. These additions elevate the dish from a simple salad to a textural masterpiece. 🥜
Protein Swaps
While ahi tuna is traditional, you can swap it for seared salmon or shrimp for a different flavor profile. For salmon, use 1 lb center-cut fillet and reduce searing time to 1-2 minutes per side.
For shrimp, toss 1 lb peeled shrimp in the marinade and cook for 2-3 minutes until pink. These swaps work beautifully while keeping the crispy sesame crust intact. 🐟
Dressing Variations
Mix up the dressing by adding 1 tsp grated ginger for warmth or 1 tbsp lime juice for brightness. For a creamy twist, replace 1 tbsp of the Japanese mayo with 1 tbsp Greek yogurt.
I also love adding ½ tsp smoked paprika to the marinade for a subtle smoky depth that pairs perfectly with the tuna. These tweaks let you customize the dish to your taste. 💫
Make-Ahead Tips
Prep the vegetables and dressing up to 2 days ahead and store them separately in airtight containers. The tuna marinade can be made 1 day ahead and refrigerated. Just before serving, sear the tuna fresh—it’s the star of the dish!
For a quick assembly, keep the components chilled until ready to plate. This ensures the salad stays crisp and vibrant. ⏰

Frequently asked questions
Can I use raw ahi tuna instead of seared?
Traditional sushi-style ahi tuna salad uses raw fish, but this BJ's-inspired version relies on the crispy seared crust for that signature restaurant texture. For a raw version, slice the tuna paper-thin and marinate in soy sauce, sesame oil, and a touch of wasabi for 10-15 minutes before assembling with the same vegetables. Just ensure your tuna is sushi-grade and handled safely.
How do I get the tuna as crispy as BJ's?
The secret is high heat and proper prep! Pat the tuna completely dry before searing, and use a clean, dry skillet over medium-high heat until it's shimmering. Press the sesame seeds firmly into the marinade before cooking—this creates the perfect crust. Cook for 2-3 minutes per side until golden brown, then rest for 2 minutes before slicing.
What if I don't have Kewpie mayo?
Japanese mayo is ideal, but you can substitute with Hellmann's or Best Foods in a pinch. For extra tang, add ½ tsp rice vinegar or a pinch of white miso paste to your regular mayo. The texture will be slightly different, but the dish will still taste delicious. For a lighter option, mix ½ mayo with ½ Greek yogurt—just reduce the honey slightly to balance the flavors.
Can I make this salad ahead of time?
Prep the vegetables and dressing 2 days ahead and store them separately in airtight containers. The tuna marinade can be made 1 day ahead, but sear the tuna fresh—it's the star of the dish! Keep all components chilled until ready to plate to maintain crispness. Assemble just before serving for the best texture and flavor.
What's the best way to serve this salad?
This dish shines when served chilled with a cold craft beer or sparkling water. For an authentic BJ's touch, plate on a wooden board or slate platter with the tuna slices fanned out over the greens. Garnish with extra sesame seeds and edible flowers for that restaurant-quality presentation. Serve immediately after assembly to enjoy the perfect contrast of warm tuna and cool vegetables.
