Grilled Albacore Tuna Kabobs Recipe: A Summer Cookout Favorite
Albacore’s firm texture works well on skewers and over direct heat. Cut the fish into even 1½-inch cubes so the pieces cook at a similar rate. For a fully cooked result, verify 145°F in the thickest cube with a food thermometer. A warm pink center is undercooked and carries additional food-safety risk.
Albacore tuna and mercury: what to know
FDA/EPA fish advice places albacore/white tuna in the “Good Choices” category. That chart is designed for people who might become or are pregnant or breastfeeding and for children; for those groups, a “Good Choice” is limited to one serving in a week. FDA notes that everyone can follow the chart. This guidance should not be rewritten as a universal one-serving-per-week rule for all adults.
Ingredients
Fish and vegetables: 1 lb albacore tuna steaks, cut into 1½-inch cubes (larger than 1 inch — smaller cubes overcook before the exterior chars properly) — 2 bell peppers (different colors), cut into 1½-inch pieces — 1 red onion, cut into 1½-inch wedges — 1 medium zucchini, cut into 3/4-inch rounds — 1 cup cherry tomatoes (separate skewer recommended — see assembly note).

Marinade: 1/4 cup good olive oil — 3 tbsp soy sauce — 1 tbsp fresh lemon juice — 1 tbsp honey or maple syrup — 2 garlic cloves, minced or grated — 1 tsp smoked paprika — 1/2 tsp black pepper — no added salt (the soy sauce provides sufficient sodium).
Method
Step 1 — Marinade. Whisk all marinade ingredients together. Place tuna cubes in a shallow dish or zip-lock bag; pour marinade over. Refrigerate 30–60 minutes. Do not exceed 2 hours: soy sauce and lemon juice are both acidic and will begin denaturing the protein on the surface of the fish beyond 2 hours, producing a mushy, mealy exterior texture. The marinade’s job is flavor penetration, not tenderizing; 30–45 minutes is sufficient.
Step 2 — Skewer assembly. The core problem with mixed fish-and-vegetable kabobs is that different ingredients cook at different rates. Bell pepper, onion, and zucchini need 4–6 minutes per side over high heat; tuna cubes need 2–3 minutes per side; cherry tomatoes need 1–2 minutes before they burst. If everything is on the same skewer, either the tuna overcooks while waiting for the vegetables, or the vegetables undercook while the tuna rests at medium. Recommended approach: separate tuna skewers and vegetable skewers. This lets you pull the tuna at the correct doneness while the vegetables continue cooking. Thread tuna cubes with small gaps between pieces — touching cubes steam rather than sear at the contact point. For the vegetable skewers, alternate bell pepper, onion, and zucchini; add cherry tomatoes to their own short skewers and grill last for 2 minutes only.

Step 3 — Prepare the grill. Heat to high (450–500°F at grate level). Clean grates and oil them with a folded paper towel dipped in neutral oil, applied with tongs. A hot, clean, oiled grate is what prevents tuna from sticking. If the grate is not hot enough when the tuna goes on, it will stick and tear when you try to turn it. If using wooden skewers, soak in water 30 minutes before use.
Step 4 — Grill. Start the vegetable skewers 2–3 minutes before the tuna. Grill the tuna over a hot, oiled grate, turning for even browning. Cooking time varies with cube size and grill temperature, so use a food thermometer rather than color or touch as the safety check. For a fully cooked result, verify 145°F in the thickest cube. A warm pink center is undercooked and carries additional food-safety risk.
Step 5 — Serve. Transfer to a platter. Squeeze fresh lemon over the tuna immediately — the acid finish brightens the soy-honey glaze. Garnish with flat-leaf parsley. Serve with garlic butter rice, quinoa, or grilled bread. Dipping sauce options: garlic aioli (see fritters recipe), spicy mayo (2 tbsp mayo + 1 tsp sriracha + 1/2 tsp sesame oil), or tzatziki.
