Variations

I’m all about making this recipe your own. Over time, I’ve played with different tweaks and loved how flexible it is—so feel free to get creative.

Dairy addition: Some friends sprinkle crumbled feta or cotija cheese on top—delicious, but totally optional.
Herb swap: If you aren’t a fan of cilantro, fresh basil or mint can be a fresh twist in the ginger sauce.
Grain bowl style: Serve the seared tuna and sauce over brown rice or quinoa for a heartier meal, especially great for weeknight lunches.

How to Make Seared Tuna with Cilantro Ginger Sauce Recipe

Step 1: Whip Up That Flavor-Packed Cilantro Ginger Sauce

Start by combining your finely chopped fresh cilantro, sliced jalapeño, grated ginger, lime juice, gluten-free tamari, Bragg apple cider vinegar, sea salt, freshly ground black pepper, and two tablespoons of extra virgin olive oil in a medium mixing bowl. Stir everything together well until the sauce is vibrant and emulsified. This sauce is the soul of the dish, so take a minute to taste and tweak the seasoning—it should feel bright, tangy, and just a little spicy to complement the tuna perfectly.

Step 2: Sear the Tuna to Perfection

Heat a skillet over medium-high and add the remaining olive oil until shimmering. While it heats, season your sushi-quality tuna steak with salt and pepper on all sides—don’t be shy as this is key for flavor. Place the tuna in the skillet and sear for 1-2 minutes per side. I usually go for about 90 seconds each side to get that beautiful crust on the outside while keeping the inside tender and rare. Remember, searing too long can dry out the fish, so keep a close eye.

Step 3: Coat and Dress with Sauce & Avocado

Once both sides of the tuna are perfectly seared, spoon half of your cilantro ginger sauce into the skillet and gently tilt the pan to coat the fish—this extra time in the pan helps the flavors meld. Then, layer the sliced avocado over the tuna and drizzle the remaining sauce on top. The creamy avocado naturally mellows the zingy sauce, making every bite a perfect harmony of flavors.

Pro Tips for Making Seared Tuna with Cilantro Ginger Sauce Recipe

Quality First: Always choose sushi-grade tuna; it makes a world of difference in flavor and texture.
Don’t Overcook: Tuna is best served rare to medium-rare, so sear quickly on high heat for the best outcome.

Sauce Balance: Taste your sauce before serving and adjust acidity or saltiness—it’s all about harmony.

Garnishes

I love garnishing with a few sprigs of fresh cilantro and thin lime wedges for an added pop of color and freshness. Some toasted sesame seeds sprinkled on top add that lovely nutty crunch that complements the softness of the tuna and avocado really well.

Side Dishes

My favorite sides to go with this are simple—steamed jasmine rice or quinoa works perfectly. If you want something lighter, a crisp cucumber salad or julienned carrot slaw dressed in rice vinegar adds that lovely crunch and balances the richness.

Creative Ways to Present

For special occasions, I’ve plated this as a seared tuna salad over baby greens with the cilantro ginger sauce drizzled artistically around the plate. Or, served as individual seared tuna slices on small appetizer spoons, topped with a dab of avocado and sauce for a killer party bite. It’s always a big hit and looks stunning.

Make Ahead and Storage

Storing Leftovers

If you happen to have leftovers (which doesn’t happen often in my house!), wrap the seared tuna tightly in plastic wrap and store in the fridge for up to one day. Keep the cilantro ginger sauce separate in an airtight container to preserve its bright flavor.

Freezing

I typically avoid freezing seared tuna since it’s best fresh and freezing can affect the texture. However, you can freeze the sauce separately in an ice cube tray if you want to prep ahead—just thaw gently before serving.

Reheating

Since tuna is best served warm but not overcooked, I gently reheat leftovers by quickly warming them in a skillet over low heat for 30 seconds per side to avoid drying out. Then, add fresh sauce and avocado slices before serving.

FAQs

Can I use regular soy sauce instead of tamari in the Seared Tuna with Cilantro Ginger Sauce Recipe?

Absolutely! Tamari is just a gluten-free soy sauce alternative, so if gluten isn’t a concern, regular soy sauce works perfectly fine and will still give you that delicious umami kick.
How rare should the tuna be when searing?

I recommend aiming for rare to medium-rare, which means about 1-2 minutes per side depending on thickness. The outside should have a nice crust, while the center stays pink and tender.
Can I prepare the cilantro ginger sauce ahead of time?

Yes! The sauce actually tastes wonderful if you make it a few hours before serving—it lets the flavors meld beautifully. Just keep it refrigerated in an airtight container.
What can I substitute for avocado if I don’t like it?

If avocado isn’t your thing, thin slices of cucumber or even ripe mango provide a refreshing, creamy contrast without overpowering the dish.
