If you’re looking for a fresh, vibrant, and satisfying dish that’s full of bold flavors and texture, my Seared Tuna with Crunchy Rice and Ponzu is it. Inspired by sushi bar appetizers and modern Japanese-American flavors, this recipe combines perfectly seared tuna with golden, crispy rice cakes and a tangy, homemade ponzu sauce. It’s the kind of plate you’d expect from a trendy restaurant, but it’s simple and fun to recreate at home.
My Crispy Rice Base Adds Crunch and Contrast
I start with seasoned sushi rice, press it into a pan, chill it until firm, then pan-fry the squares until golden and crunchy. The crispy exterior contrasts perfectly with the soft interior and adds a satisfying texture to each bite. I love how the warm rice anchors the cool, delicate tuna on top.
Perfectly Seared Tuna is the Star
I use fresh, high-quality ahi tuna and give it a quick sear in a hot pan so the edges are golden but the center stays rare and silky. The result is buttery, tender slices that melt in your mouth. A little salt and pepper is all it needs, since the ponzu does the rest of the flavor work.
My Homemade Ponzu Sauce Brightens Everything
For the sauce, I whisk together soy sauce (or tamari), rice vinegar, fresh lime juice, and just a splash of mirin. Sometimes I add a few drops of sesame oil or fresh ginger for more depth. This zesty ponzu ties the whole dish together with brightness and balance.
Garnishes That Add Flavor and Flair
To finish, I like to add sliced scallions, toasted sesame seeds, and sometimes thin slices of avocado or radish. A bit of wasabi mayo on the side is a fun touch, and microgreens or shiso leaves make it pop visually. A sprinkle of flaky salt just before serving pulls all the flavors into harmony.
Why I Keep Coming Back to This Recipe
This dish hits all the marks for me. It’s light yet satisfying, savory and fresh, and always looks beautiful on the plate. It’s perfect for entertaining but also easy enough for a quick dinner. You can make the crispy rice ahead and sear the tuna at the last minute. It’s naturally gluten-free (with tamari) and full of protein and healthy fats.
Whether you’re a tuna lover or just want to try something that feels a little elevated but totally doable, my Seared Tuna with Crunchy Rice and Ponzu delivers bold flavor, satisfying crunch, and total wow factor.

Instructions
Rice
Preheat oven to 400°F. Add the rice (1 quart) to a parchment-lined baking sheet. Season with sesame oil (4 Tbsp) and soy sauce (1 Tbsp), and toss. Bake for 1 hour, tossing 1-2 times until golden brown and crunchy.
Tuna
Season the tuna steaks (1 lb) with salt. Then add the sesame seeds (1 cup) to a plate and press the tuna into the seeds firmly to make the seeds adhere. Set aside.
Preheat a large pan over high heat. Add the oil (3 Tbsp). Once hot, sear the tuna for 1 minute on each side (for rare, longer for other temperatures). Remove to a cutting board. Then slice against the grain into 1/2” thick slices. Keep in the fridge until ready to serve.
Ponzu
Mix all ingredients together in a container
Assembly
Just before ready to serve, toss the rice and assembly ingredients together. Then toss in ponzu to taste. Have people make their bowls with the tuna slices on top.
