Fresh tuna, crisp celery crowns, and a signature tangy dressing bring BJ's flavors home effortlessly.
| Ingredient | Amount | Notes |
|---|---|---|
| Fresh Ahi Tuna Steak 🐟 | 1 lb | Sushi-grade, 1-inch thick slices |
| Romaine Lettuce 🥬 | 1 whole | Heads separated into leaves |
| Celery Stalks 🧅 | 3 whole | Fresh, crisp variety |
| Red Leaf Lettuce 🥬 | 1 cup | Shredded for texture |
| Mayonnaise 🥫 | ½ cup | High-quality, not low-fat |
| Dijon Mustard 🍯 | 1 tbsp | Mild for subtle tang |
| Honey 🍯 | 1 ½ tbsp | Light, not thick |
| Lemon Juice 🍋 | 1 tbsp | Freshly squeezed |
| Olive Oil 🫒 | 1 tbsp | Extra-virgin for richness |
| Salt 🧂 | ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ¼ tsp | Freshly ground |
| Sesame Seeds 🌾 | 1 tsp | Toasted for garnish |
| Vegetable Oil 🫒 | 2 tbsp | High smoke point |
| Garlic Powder 🧄 | ½ tsp | For celery crowns |
The tuna is non-negotiable—sushi-grade is a must for that perfect sear without overcooking. Look for 1-inch thick slices at the seafood counter, not pre-cut packages. Whole Foods or Trader Joe's carry excellent options, but ask the fishmonger for the freshest cut. The celery should be crisp and bright green, not rubbery or yellowing. For the dressing, high-quality mayo makes all the difference—Hellmann's or Duke's are reliable choices, but avoid anything labeled 'light' or 'low-fat'.
No sushi-grade tuna? Fresh salmon steak works in a pinch, though the texture will differ slightly. Substituting honey? Maple syrup at a 1:1 ratio keeps the sweetness balanced. If you're avoiding mayo, Greek yogurt with a splash of lemon mimics the creaminess. For the celery crowns, red bell pepper strips add a nice crunch alternative. Always toast your sesame seeds in a dry pan for 30 seconds—it enhances their flavor dramatically.
Tuna slices should be seared immediately and kept chilled until serving. The celery crowns stay crisp for up to 4 hours in the fridge if stored in a sealed container. The dressing keeps for 5 days in the refrigerator, though the flavor peaks within the first 2 days. For gatherings, double the dressing and make celery crowns ahead—they're the only component that doesn't improve fresh out of the fridge.
Why You'll Love This Recipe
- No-Seam Assembly: This salad comes together like a puzzle with missing pieces—just slice the tuna thin, chop the celery, and layer it all. Honestly, I’ve made it while scrolling through my phone; the hardest part is deciding whether to use the red leaf or romaine first.
- Butter-Soft Tuna Magic: That first bite of perfectly seared ahi tuna, still warm with a whisper of mayo? It’s the kind of texture that makes you pause mid-chew. The trick is searing the tuna just until it’s opaque—no overcooking, just pure, buttery satisfaction.
- Lunchbox Hero: Between us, this is my go-to for work lunches or picnics—packs like a dream, stays fresh for days, and still tastes like a restaurant meal. The red leaf adds that crunch no sad office salad ever does, and the tuna holds up better than you’d think.
- Budget Luxe Hack: Ahi tuna feels fancy, but this recipe stretches it like a pro. I’ll often buy the smaller steak, slice it paper-thin, and suddenly one portion feels like a splurge instead of a waste. Plus, mayo and celery are cheap—this is gourmet on a shoestring.
Step-by-step instructions for Bj's Brewhouse ahi tuna salad
Master the perfect sear and crispy celery crowns for restaurant-quality tuna salad at home.
Prepare the Crisp Celery Crowns
Cut the 3 whole celery stalks lengthwise into thin strips, about 1/8-inch thick, working from the base up. This creates elegant "crowns" that will crisp beautifully. In a small bowl, toss the celery strips with 2 tablespoons vegetable oil and 0.5 teaspoon garlic powder until evenly coated. Arrange them in a single layer on a parchment-lined baking sheet, spacing them evenly.
Bake at 400°F for 12-15 minutes until the edges turn deep golden brown and the celery feels crisp to the touch. Watch closely after 10 minutes—they crisp quickly and can burn if left unattended. Remove from the oven and transfer to a paper towel-lined plate to drain excess oil while you prepare the tuna.
Sear the Ahi Tuna to Perfect Doneness
Pat the 1 lb fresh ahi tuna steak dry with paper towels—this ensures maximum contact with the hot pan and a better sear. Heat 1 tablespoon olive oil in a large skillet over high heat until it shimmers. Season both sides of the tuna generously with 0.5 teaspoon salt and 0.25 teaspoon black pepper. Place the tuna in the pan and sear for 2-3 minutes per side for medium-rare (internal temperature 125-130°F).
You'll know it's ready when the edges are deep brown and the center still feels slightly cool to the touch. Remove the tuna from the pan and let it rest for 5 minutes before slicing. This resting period allows the juices to redistribute, ensuring every bite stays tender. Slice the tuna against the grain into 1/4-inch thick pieces for easy serving.
Assemble the Signature Dressing
In a medium bowl, combine 0.5 cup mayonnaise, 1 tablespoon Dijon mustard, 1.5 tablespoons honey, and 1 tablespoon lemon juice. Whisk vigorously until the mixture is smooth and fully emulsified—this creates the signature sweet-tangy balance that defines Bj's version. The dressing should be thick enough to coat the back of a spoon but still flow smoothly.
Taste and adjust seasoning if needed, adding a pinch more salt or lemon juice as necessary. Set the dressing aside while you prepare the remaining salad components. This step is where the magic happens—the perfect harmony of creamy, sweet, and tangy flavors that pairs beautifully with the seared tuna.
Build the Salad Platter
Arrange the 1 whole Romaine lettuce leaves on a large platter, overlapping slightly to create a lush bed. Scatter the 1 cup shredded red leaf lettuce evenly over the Romaine for added texture and color contrast. Gently fold the crisp celery crowns into the salad, distributing them evenly across the platter. Place the sliced ahi tuna in an attractive arrangement over the lettuce and celery.
Drizzle the prepared dressing generously over the tuna and vegetables, allowing it to pool slightly at the bottom of the platter. Sprinkle 1 teaspoon toasted sesame seeds evenly over the top for a final touch of crunch and visual appeal. Serve immediately while the tuna is still warm and the celery remains crisp.
Pro Tips For Making Bj'S Brewhouse Ahi Tuna Salad
- SEAR THE TUNA FAST: Hit that tuna steak with a screaming-hot pan—just 30 seconds per side max. Overcooking turns it rubbery, and this recipe relies on that perfect rare, buttery center. Flip once, then let it rest 2 minutes before slicing, or it’ll dry out faster than a bad date.
- CHOP CELERY SMALLER: Tiny dice, not thin sticks. The BJ’s version blends celery into the mayo mix, so if you’re keeping it chunky, cut it into 1/8-inch pieces—it makes the salad creamy and textured, not crunchy. (Yes, it takes 30 seconds extra, but it’s worth it.)
- DRESS LETTUCE LAST: Toss the romaine and red leaf with mayo right before adding the tuna. Lettuce wilts fast, and soggy greens ruin the crisp contrast this salad needs. Keep the dressing separate until the final mix—trust me, you’ll notice the difference.
- USE COLD MAYO: Straight from the fridge, always. Room-temperature mayo gets greasy and clumps when mixed with tuna juice. Cold mayo stays smooth, thick, and clings better to the slices—plus, it cuts through the richness without overpowering. No excuses.
Perfect pairings for this recipe
Signature Side Dishes
BJ's Brewhouse-style garlic bread is the perfect partner for this salad—its buttery, garlicky crust soaks up any leftover dressing. I love using a French baguette brushed with 3 tablespoons melted butter mixed with 1 minced garlic clove and ½ teaspoon parsley.
Toast it in the oven at 375°F for 10 minutes until golden and crisp. 🍞
For a lighter option, serve with their famous crispy onion strings. Toss 2 cups thinly sliced sweet onions with 1 tablespoon olive oil and ½ teaspoon smoked paprika, then bake at 400°F for 20-25 minutes until caramelized. The sweetness contrasts beautifully with the tuna's savory notes.
Dressing Variations
For a lighter dressing, swap mayo for ¼ cup Greek yogurt and add 1 teaspoon lemon zest to brighten the flavor. I also like reducing the honey to 1 tablespoon to keep it from overpowering the delicate tuna.
This version works well for those watching their fat intake while still delivering that signature tang.
Want extra heat? Stir in ½ teaspoon sriracha or 1 teaspoon hot honey into the dressing before serving. The spicy kick pairs surprisingly well with the crisp celery and creamy tuna. Trust me, your guests will love it!
Drink Pairings
A crisp Sauvignon Blanc from New Zealand is my go-to pairing—its citrus notes complement the lemon in the dressing and the freshness of the tuna. Look for wines with bright acidity like Cloudy Bay or Oyster Bay to cut through the richness of the salad. 🍷
For beer lovers, a Belgian witbier like Hoegaarden adds a refreshing contrast with its coriander and citrus flavors. The effervescence cleanses the palate between bites of the creamy salad. If you prefer something lighter, a Mexican lager like Modelo works perfectly too.
Garnish Upgrades
Add thinly sliced scallions for a fresh, oniony bite that brightens the salad. I like to slice 3 scallions on the bias and sprinkle them over the tuna just before serving. The color contrast makes the platter look even more inviting. 🌱
For a smoky twist, sprinkle ½ teaspoon smoked paprika over the tuna before adding the dressing. The subtle smokiness enhances the seared flavor without overpowering it. This works especially well if you're serving the salad at a BBQ or summer gathering.

Frequently asked questions
Can I make this Ahi Tuna Salad without searing the tuna?
Yes! For a no-sear version, simply slice the 1 lb sushi-grade tuna into 1/4-inch pieces and marinate in 1 tablespoon soy sauce, 1 teaspoon sesame oil, and 1 teaspoon honey for 10 minutes before assembling. This adds flavor without cooking, but the texture will be more delicate than seared.
How do I keep the celery crowns crisp for serving?
Bake the celery crowns just before serving and store them in an airtight container at room temperature. If prepping ahead, bake them up to 4 hours in advance and reheat at 350°F for 3-5 minutes to restore crispness. Never refrigerate baked celery—it loses crunch quickly.
What's the best way to store leftovers?
Store the tuna and dressing separately in airtight containers in the fridge for up to 24 hours. Reheat the tuna gently in a skillet for 1 minute per side before reassembling. The celery crowns should be eaten fresh or discarded after 4 hours. The dressing keeps for 5 days but tastes best within 2 days.
Can I substitute fresh tuna with canned?
Not for this recipe—fresh sushi-grade ahi tuna is essential for both safety and texture. Canned tuna lacks the delicate flavor and moisture needed for this dish. If you must use canned, try a high-quality albacore in a creamy salad with different toppings, but it won't replicate BJ's signature taste.
How do I adjust the recipe for a crowd?
Double the ingredients and use a large platter (12x18 inches). For 8 servings, you'll need 2 lbs tuna, 6 celery stalks, and 1 cup dressing. Prep the celery crowns and dressing first, then sear the tuna in batches. Keep everything chilled until serving to maintain freshness.
