This recipe is…
These chili-lime seared tuna steaks come from Cook Once Dinner Fix and are incredibly satisfying. If you haven’t cooked tuna before, don’t worry — the method is straightforward and quick. The steaks marinate in a tangy Thai chili–lime sauce, then are seared to form a light crust while remaining tender inside.
Ingredients Needed
Gather the following for flavorful seared ahi tuna:
- 2 tablespoons Thai chili sauce
- 2 tablespoons soy sauce (or tamari for gluten-free)
- 2 tablespoons fresh lime juice (from 1 lime)
- 2 tablespoons extra-virgin olive oil
- 1½ pounds ahi tuna steaks
- 2 tablespoons salted butter or olive oil spray
- 2 tablespoons chopped fresh cilantro, for garnish
- 1 tablespoon white sesame seeds, for garnish
- Lime wedges, for serving
Ingredient Modifications
Simple swaps and options:
- Make it dairy-free: use olive oil instead of butter for searing.
- Use another tuna variety: if ahi is unavailable or pricey, any tuna steaks will work well.
How to Sear Ahi Tuna Steak
Quick overview of the steps to prepare this dish:
- Marinate the tuna steaks — In a small bowl, whisk Thai chili sauce, soy sauce, lime juice, and olive oil. Place the tuna in a large zip-top bag, add the marinade, and refrigerate for at least 10 minutes or up to 2 hours.
- Sear the tuna steaks — Heat butter (or oil) in a skillet over medium heat. Discard the marinade, add the steaks, and cook 3–4 minutes per side until a light crust forms and the center remains slightly pink.
- Garnish and serve — Divide the tuna among plates, spoon the quinoa or rice alongside, and finish with chopped cilantro, sesame seeds, and lime wedges.
Is it hard to sear ahi tuna?
No — searing ahi is straightforward. Use a hot pan and sear for 3–4 minutes per side. The exterior develops a crust while the inside stays tender and slightly pink.
How long does it take to make the best seared ahi tuna recipe?
Searing is quick (about 3–4 minutes per side). Plan for at least 10 minutes of marinating time; total active time is short, making this a fast weeknight dinner.
How to Store and Reheat
Store leftovers in an airtight container in the refrigerator for up to 5 days. Freezing cooked tuna is not recommended because the texture often suffers. Reheat gently in a pan over low heat or briefly in the microwave until just warmed through.
Frequently Asked Questions
Yes. For most people, tuna is a lean, heart-healthy protein rich in omega-3s and B vitamins, plus minerals like selenium and zinc.
Avoid overcooking to prevent dryness. Sear 3–4 minutes per side and aim for a pink center — that texture is safe and delicious.
An internal temperature around 115°F yields a tender, slightly pink center. Use a meat thermometer for accuracy.
Quinoa, rice, farro, or other grains pair nicely. For vegetables, try roasted broccoli, steamed broccoli, oven-roasted green beans, or a simple arugula salad.
