Why You’ll Love this Tuna Appetizer
Growing up in Japan I enjoyed a lot of delicious fresh fish in my childhood and I must say, tuna is my all time favorite! I could happily eat it every day if given the chance—and I love to indulge when we visit Japan, where you can find some of the world’s best! Here in Copenhagen we also have decent fresh fish and luckily, it’s pretty easy to find delicious tuna steaks.
One of my favorite fish appetizers, always a hit with our guests, is this delicious fresh Asian salad with sesame-seared tuna steaks. The tuna is seared to perfection and served with chili and sesame sauce. This appetizer is both light and fresh, and even those who aren’t keen on raw fish can enjoy it, as the tuna steaks are cooked on the outside giving a nice crispy bite. The contrast of the crispy sesame crust with the raw center creates a fantastic texture. Combined with the spicy chili, crunchy salad, and sweet sesame sauce, it offers an incredible Asian flavor experience.
3 reasons why you’ll love this tuna appetizer

Two Delicious Asian Dipping Sauces
This tuna appetizer has two delicious Asian sauces that are wonderfully simple to make:
- Ginger sauce: Fresh and zesty with a spicy kick from finely grated ginger. Balanced with soy sauce, sesame oil, and a splash of lemon juice, it adds a wonderful bright, tangy flavor to the tuna.
- Sesame dipping sauce: Nutty, tangy, and savory with a rich roasted flavor from toasted sesame seeds, soy sauce and rice vinegar. This thick sauce is the perfect dipping sauce for the seared tuna.
Recipe Variations
Feel free to mix up the greens for this tuna appetizer. In my recipe, I pair the seared tuna with fresh mâche salad (lamb’s lettuce), spring onions, chili, and cilantro, but you could also add edamame or shredded cabbage to the mix.
You can also turn this dish into a main course by adding more vegetables such as seared bell peppers and leeks, and serving it with rice on the side.
