How to Make seared tuna
1. Whisk Together: In a bowl, whisk together 1/4 cup low sodium soy sauce, 2 tablespoons sesame oil, 1 tablespoon rice vinegar, 1 teaspoon honey, 1 clove minced garlic, and 1 teaspoon grated ginger. This marinade will pack your tuna steaks with flavor.
2. Marinate the Tuna: Place the 4 pieces of fresh, sushi-grade tuna steaks in a shallow dish and pour the marinade over them. Let these beautiful steaks marinate for about 10 minutes to absorb all those delicious flavors.
3. Heat the Skillet: Heat a skillet over high heat until it’s sizzling hot. Remove the tuna from the marinade and sear each steak for just 1-2 minutes on each side for that perfect rare finish, or longer if you prefer them cooked more.
4. Slice and Serve: Remove the tuna from the skillet and let rest for a minute before slicing against the grain. Garnish with 2 tablespoons of toasted sesame seeds and sliced green onions for an extra pop of flavor and color.
Optional: For added crunch, serve with a sprinkle of crushed chili flakes.

Pro Tips for seared tuna
- Fresh is Best: Always choose fresh, sushi-grade tuna steaks for optimal flavor and texture. This ensures your seared tuna is both delicious and safe to eat.
- Marinating Time: Don’t exceed 10 minutes for marinating; longer can make the tuna too salty. This brief soak infuses flavor without overpowering its natural taste.
- High Heat Searing: Ensure your skillet is hot enough before adding the tuna. A quick sear locks in moisture and creates a beautiful crust without overcooking.
- Rare or Well-Done: Remember, seared tuna is best enjoyed rare to medium-rare. If you prefer it more cooked, adjust searing time carefully to avoid dryness.
- Cutting Technique: Slice against the grain for tender pieces that melt in your mouth. Cutting with the grain can result in chewy bites, so pay attention!
- Garnish Wisely: Toasted sesame seeds enhance flavor and crunch. Don’t skip this step; they elevate your dish from simple to sensational!
How to Store and Freeze seared tuna
- Fridge: Store leftover seared tuna in an airtight container for up to 3 days. Make sure it’s cooled to room temperature before sealing.
- Freezer: For longer storage, wrap the tuna steaks tightly in plastic wrap and then in aluminum foil. They can be frozen for up to 2 months.
- Reheating: To reheat, gently warm seared tuna in a skillet over low heat for 2-3 minutes per side, just until heated through. Avoid overcooking to maintain tenderness.
- Marinade Storage: If you have leftover marinade, store it in the fridge in a sealed container for up to 5 days.
seared tuna Your Way
Feel free to get creative and make this dish your own with these delightful twists!
- Spicy Twist: Add a teaspoon of Sriracha or chili paste to the marinade for a fiery kick. This will give your tuna an exciting heat that dances on the palate, balancing perfectly with its natural flavors.
- Citrus Burst: Incorporate the juice of half a lime or orange into the marinade for a refreshing zing. The citrus notes will brighten the dish, bringing a vibrant contrast to the rich tuna.
- Herb Infusion: Mix in fresh herbs like cilantro or basil into the marinade for an aromatic touch. This will not only enhance flavor but also add a beautiful pop of color when served.
- Nutty Flavor: Replace sesame oil with peanut oil for a different nutty dimension. This swap offers an unexpected depth that complements the seared exterior of the fish beautifully.
- Sweet Variation: Use maple syrup instead of honey for a deeper sweetness. The maple flavor infuses warmth that harmonizes perfectly with the savory elements of the dish.
- Pickled Garnish: Top with pickled ginger instead of green onions for an added tangy crunch. This twist provides an exciting flavor contrast while maintaining the dish’s elegant presentation.
- Soy-Free Option: Substitute coconut aminos for soy sauce to keep it soy-free without sacrificing taste. This option brings a slightly sweeter note, perfect for those avoiding soy products.

How long should I marinate the tuna?
