How to Smoke a Tuna Loin: Step-by-Step Recipe

Smoked Tuna Loin

Our Smoked Tuna Loin recipe is one you’ll return to again and again. It’s straightforward, low-effort, and rewards you with tender, deeply flavored fish that’s perfect for slicing and sharing. The process begins with a simple brown sugar and kosher salt cure, followed by a low-temperature smoke on a pellet grill until the tuna is savory, flaky, and richly aromatic.

Smoked Tuna Loin

Don’t be put off by the total time—about 14 hours from start to finish—because most of that is hands-off curing time in the refrigerator. Prepare the cure and drop the loins in before bed, let them rest overnight, rinse and pat dry the next morning, then smoke. It requires some planning but very little active work. The result is a versatile smoked albacore that’s excellent as a snack, an appetizer, or incorporated into more complex dishes.

For a quick, elegant bite, toast crostini in garlic olive oil, spread a thin layer of herbed cream cheese, then top with a generous slice of smoked tuna. It also shines in tuna melts or as a premium substitute for canned tuna in a classic tuna salad.

Before you start, gather the essentials below. For exact quantities and timing see the recipe card later in this post.

• Fresh tuna loins – Choose the freshest albacore (or another firm tuna) you can find. Freshness affects both texture and flavor.
• Dark brown sugar – Adds a touch of molasses sweetness to balance the salt and smoke.

How to Make This Recipe (Overview)

Below is a concise overview of the process so you can see the steps at a glance. Use the full recipe card for exact amounts, times, and the printable version.

1. Prep the tuna: Pat the loins dry with paper towels and trim if needed.
2. Cure the fish: Combine dark brown sugar and kosher salt. Place the loins in a large zipper bag, add the cure, and gently shake to coat. Refrigerate for about 12 hours.
3. Rinse and dry: After curing, rinse the loins under cold water to remove excess cure. Pat dry and refrigerate uncovered for 1–2 hours to form a pellicle (a tacky surface that helps smoke adhere).
4. Smoke the tuna: Preheat a pellet grill or smoker to about 175°F (80°C). Place the loins directly on the grates and smoke for approximately 1½ hours, or until the tuna flakes easily and reaches the texture you prefer.
5. Cool and serve: Chill the smoked loins before slicing. Serve thinly sliced cold, or gently warm and use in recipes.

Instructions

1. Lay tuna loins on a cutting board and wrap in paper towels. Pat dry thoroughly and remove towels.
2. Mix the dark brown sugar and kosher salt in a bowl until combined.
3. Place the loins in a large zipper-style bag. Pour the cure over the fish, seal, and gently shake to coat all sides.

8. Remove the tuna and chill in the refrigerator before slicing thinly. Serve cold on crostini, in sandwiches, or as desired.
