How to Make Tuna Steaks on the Grill-Easy Step-by-Step Guide
Grilling tuna steaks is easier than you think—if you know the tricks to lock in flavor and avoid dryness.
In this guide, you’ll learn to pick the best cuts, season smartly, and grill like a pro—even if you’re a beginner.
Why Grill Tuna Steaks?
Tuna steaks on the grill cook fast, retain nutrients, and deliver a smoky flavor.
Pro Tip: Tuna is not just for sushi. Grilling caramelizes the surface, adding depth.
Choosing the Right Tuna Steaks
Prepping Tuna Steaks for the Grill
- Pat dry with paper towels to help seasoning stick.
- Season: Rub with olive oil, salt, pepper, and a dash of smoked paprika.
- Marinate (optional): 30 mins in soy sauce, ginger, and garlic for bold flavor.
Interesting Fact: Tuna’s dense flesh absorbs marinades slower than chicken—keep it under 1 hour.
Grilling Tuna Steaks: Step-by-Step
- Heat the grill: Scrape grates clean, then preheat to high (450–500°F).
- Sear: Place steaks diagonally on grates. Grill 2–3 mins per side for medium-rare.
- Rest: Let sit 5 mins to redistribute juices.
Common Mistake: Flipping too early. Wait for grill marks to form.
Serving Ideas for Grilled Tuna
- Top with: Mango salsa, wasabi mayo, or lemon butter.
- Pair with: Quinoa salad, grilled asparagus, or jasmine rice.
- Garnish: Fresh cilantro or toasted sesame seeds.
Pro Tip: Slice against the grain for tender bites.

FAQs About Grilled Tuna Steaks
Q: Can I use frozen tuna?
A: Yes! Thaw overnight in the fridge for best texture.
Q: How do I know when it’s done?
A: Aim for an internal temperature of 125°F (medium-rare).
Q: How long to grill tuna steaks?
A: Grill 1-inch-thick tuna steaks 2–3 minutes per side over high heat.
Q: Is it better to grill or fry tuna steaks?
A: Grilling is ideal for smoky flavor and charred crust, while pan-frying (in cast iron/stainless steel) offers more control. For quick searing, both work well – grill for outdoor flavor, fry for indoor convenience.
Q: What is the best method of cooking tuna?
A: For thick tuna steaks, quick high-heat methods are best:
- Grilling (2-3 mins/side) – Best for smoky flavor & char
- Pan-searing (in cast iron) – Ideal for perfect crust indoors
- Sous vide (45 mins @ 115°F) – Most precise for edge-to-edge doneness
Key Tip: Never cook past medium-rare (125°F) – tuna dries out fast!
