Ingredients
  

For the Tuna:

  • Ahi Tuna Steaks – Look for sushi-grade tuna ideally yellowfin or bigeye, for the freshest, most tender results.
  • Avocado Oil or Sesame Oil – High smoke-point oils ensure a perfect sear without burning.
  • Sea Salt & Black Pepper – Enhances the natural umami flavors of the tuna.

For the Marinade:

  • Soy Sauce or Tamari – Adds a deep savory element. Use tamari for a gluten-free option.
  • Lime Juice – A touch of acidity brightens the flavors.
  • Sesame Seeds – Optional but they add a delicious nutty crunch when searing.
  • Fresh Ginger & Garlic – Infuses warmth and boldness into the marinade.
  • Honey or Maple Syrup – A hint of sweetness balances the saltiness.
  • Sriracha or Red Pepper Flakes – For a little heat adjust to taste.

Optional Garnishes & Serving Ideas:

  • Wasabi Mayo or Spicy Aioli – A creamy spicy kick.
  • Ponzu Sauce – A citrusy soy-based dipping sauce for extra depth.
  • Pickled Ginger & Cucumber Salad – Light refreshing pairings.
  • Steamed Rice or Greens – Ahi tuna pairs beautifully with simple bases.

Instructions
 

Marinate the Tuna (Optional but Recommended)

  • For extra flavor, marinate your ahi tuna steaks in a simple blend of:
  • ✔️ Soy sauce for umami richness
  • ✔️ Fresh lime juice for brightness
  • ✔️ Garlic & ginger for warmth and depth
  • ✔️ A drizzle of honey to balance the flavors
  • Let the tuna soak up the goodness for 15-30 minutes in the fridge. If you're short on time, even a quick 5-minute soak will add a flavor boost!

Prep for the Perfect Sear

  • Pat the tuna dry with a paper towel—this helps achieve that crispy, golden crust.
  • Season both sides with sea salt, black pepper, and sesame seeds (if using).
  • Preheat a cast iron skillet or heavy-bottomed pan over high heat. Add avocado oil or another high-smoke-point oil to prevent sticking.

Sear the Tuna – Quick & Hot!

  • 🔥 Cook Time: 45-60 seconds per side 🔥
  • Place the tuna in the hot skillet and let it sear undisturbed for 45-60 seconds—this creates that beautiful crust while keeping the center rare.
  • Flip and repeat on the other side. If you prefer it more cooked, sear for an extra 30 seconds per side (but be careful not to overdo it!).
  • Once done, transfer the tuna to a cutting board and let it rest for a minute before slicing.

Slice & Serve

  • Use a sharp knife to slice the tuna against the grain into thin, even pieces.
  • Serve immediately with your favorite sauces and sides—try wasabi mayo, ponzu sauce, steamed rice, or a crisp cucumber salad.
