If you’ve never grilled albacore tuna before, this is your invitation to try it. Traeger Grilled Albacore Tuna Loin requires only a few minutes over high heat for a fast sear, then a short chill in the refrigerator for easy slicing and serving. The quick sear locks in savory flavor while leaving a silky, nearly-rare center. A sprinkle of togarashi adds mild heat and citrusy umami, and chilled curled green onions provide crisp contrast and a fresh finish. This is a clean, cool dish that’s perfect to prep ahead and serve for a crowd.
Traeger Grilled Albacore Tuna Loin
If you live near the coast, pick up sushi-grade albacore loins while they’re fresh. Albacore is versatile and far more interesting than the usual canned-tuna options. This recipe is quick to execute and yields an elegant, restaurant-style plate without any advanced technique.
Use the freshest albacore you can find when serving it rare or nearly rare. For added safety, commercially recommended practice for raw or nearly raw fish is to hold it at -7°F (-22°C) for at least seven days prior to serving if you’re concerned about parasites.
Don’t skip the green onions: chilled, curled scallions contribute a crunchy bite, mellow their sharpness, and provide an attractive garnish.

How To Make This Recipe (Overview)
This overview gives a clear picture of the preparation. Follow the detailed steps in the full recipe card below while cooking.
- Prep the tuna: If frozen, thaw fully. Pat dry and chill briefly in the refrigerator to firm the surface.
- Season: Remove from fridge, pat dry, and season all sides with salt and togarashi.
- Quick sear: Heat a grill or a heavy pan until very hot. Add a thin layer of oil and sear the tuna briefly—just enough to color the outside while keeping the center rare. A few seconds per side is sufficient depending on thickness; do not overcook.
- Chill: Transfer the seared tuna to a plate, cover, and chill for about 30 minutes to firm and cool the fish for slicing.
- Slice and serve: Thinly slice green onions and soak in ice water for 20 minutes to curl. Slice the tuna into 1/4-inch pieces with a sharp knife and top with the curled green onions. Serve chilled with soy sauce, wasabi, and pickled ginger.
Recipe FAQ
Can I make this ahead of time?
Yes. Make it up to a day ahead, tightly wrapped and refrigerated. Slice just before serving for the freshest texture.
How should I store leftovers?
Wrap tightly in plastic or place in an airtight container in the refrigerator. Consume within 24 hours for best texture and flavor.
Can I reheat this?
No. This preparation is intended to be served cold. Reheating will overcook the tuna and ruin its delicate texture.
What is a good substitute for togarashi?
Mix chili flakes with sesame seeds and a little citrus zest for a similar spicy-citrus flavor profile.
What if I don’t like rare tuna?
If you prefer tuna cooked through, sear it slightly longer to your preferred doneness—but keep in mind the texture will change and it will no longer be sushi-style.

Ingredients
- 1 pound albacore tuna loin
- 1/2 teaspoon salt
- 1 tablespoon togarashi seasoning
- 2 tablespoons olive oil (or neutral oil)
- 1 bunch green onions (scallions)
Instructions
- If frozen, thaw the tuna completely and pat dry.
- Wrap the loin in paper towels and refrigerate for about 30 minutes to dry the surface and firm the fish.
- Remove the tuna, unwrap, and place on a cutting board. Season all sides with salt and togarashi.

- Transfer the seared tuna to a plate, cover, and refrigerate for 30 minutes to chill and set for slicing.
- While the tuna chills, slice green onions very thin (less than 1/8″ wide) lengthwise and place them in an ice bath for 20 minutes to curl and mellow their sharpness.
- With a very sharp knife, slice the chilled tuna into 1/4″ slices. Arrange on a platter and top with curled green onions.
- Serve chilled with soy sauce, wasabi, pickled ginger, and any preferred condiments.
