Ingredients (2–4 servings)
Tuna & Crust
- 2–4 sushi-grade ahi/yellowfin tuna steaks (6–8 oz each, 1–1½ inches thick)
- 1 tbsp neutral oil (avocado or grapeseed)
- 1 tbsp sesame seeds (black + white mix = gorgeous)
- 1 tsp kosher salt
- ½ tsp black pepper
- ½ tsp garlic powder
- ½ tsp coconut sugar or brown sugar
- Optional kick: ½ tsp cayenne or togarashi
Quick Dipping Sauce
- ¼ cup soy sauce or tamari
- 1 tbsp rice vinegar
- 1 tsp sesame oil
- 1 tsp honey
- Squeeze lime + pinch chili flakes
Garnish
- Sliced scallions, extra sesame seeds, wasabi mayo
Essential Tools and Equipment
- Air fryer (basket or oven style)
- Tongs
- Sharp knife for slicing
Step-by-step process
- Pat tuna completely dry — moisture is the enemy of crust.
- Mix crust — combine sesame seeds, salt, pepper, garlic powder, sugar, and cayenne in a small bowl.
- Coat — brush steaks lightly with oil → press firmly into crust mixture on all sides.
- Preheat air fryer 3 minutes at 400 °F (204 °C).
- Cook — place steaks in a single layer (no overlap). Air fry 6–8 minutes total:
- 6 min = cool red center (rare, 115–120 °F internal)
- 7 min = warm red center (medium-rare, 125 °F)
- 8 min max — do NOT go longer. No flipping needed!
- Rest 3 minutes → slice ¼-inch thick against the grain.
- Serve immediately, fanned over greens with dipping sauce.
Mistakes to avoid
- Frozen or non-sushi-grade — gray, dry disaster.
- Overcooking — 8 minutes max; tuna turns chalky fast.
- Wet steaks — no crust; dry aggressively.
- Crowding basket — air needs to circulate.
- Skipping preheat — weak sear.
Variations of the Best Air Fryer Tuna Steak
- Teriyaki — brush with teriyaki glaze last 1 minute.
- Everything Bagel — swap sesame for everything seasoning.
- Cajun Blackened — heavy Cajun spice + butter spray.
- Poke Bowl — cube after cooking + poke sauce.
- Salad Niçoise — chill & flake over greens.
Tips for better storage & make-ahead
- Leftovers — fridge up to 2 days; eat cold or room-temp (do not reheat).
- Meal prep — sear, chill, slice → instant protein all week.
- Freezer — raw steaks freeze beautifully up to 3 months.
Frequently Asked Questions
