Soften sliced onion in a pan, add chopped tomato, then place the bonito on top and cover until cooked through. Turn the fish gently and only once if possible, so the slices stay intact.
No. Bonito is a tuna-like fish in the mackerel family, but it is not the same as the tuna commonly sold in cans. Its firm, flavorful flesh works well in slices cooked with tomato and onion.
It tastes savory and rich, with a firm, meaty fish texture balanced by sweet onion and tangy tomato. The tomato juices also make a simple sauce that keeps the bonito from tasting dry.
Use a well-heated, lightly oiled pan and pat the bonito dry before adding it. Let each slice cook undisturbed until it releases more easily, then turn it carefully rather than moving it repeatedly.
Yes. Thaw the bonito in the refrigerator, drain it well, and pat it dry before cooking. Excess moisture can water down the tomato mixture and prevent the fish from browning.
Serve it with rice, roasted potatoes, or a crisp green salad. Bread is also useful for soaking up the onion-and-tomato juices, making the meal feel complete without adding another rich dish.
The bonito is cooked when its flesh turns opaque and separates easily with a fork. Check the thickest part of a slice, and avoid prolonged cooking because bonito can become dry and firm.
Yes. Bake the onion, tomato, and bonito together in a covered ovenproof dish instead of cooking them in a pan. Uncover near the end if you want the tomato juices to reduce.
Refrigerate leftovers in a covered container once they have cooled, and eat them within a few days. Reheat only the portion you need over low heat to help keep the bonito from drying out.
Yes. Canned chopped tomatoes can replace fresh tomatoes, though they make a softer, saucier dish. Let the mixture simmer briefly before adding the bonito so excess liquid can reduce.

Pan-Fried Bonito with Tomato and Onion is a home-style fish dish made by cooking bonito with sliced onion and tomato in a pan. Bonito is especially familiar in Turkish cooking when it is in season, and the vegetables soften as they cook alongside the fish, making a simple, savoury sauce.
Serve it hot with bread and a crisp salad, or add rice for a more substantial meal. Bonito has a meaty texture and a pronounced flavour that holds up well to the sweet onion and tangy tomato. The dish is protein-rich, with 20.5 g per 100 g. For a lighter panful, use just a little oil and let the vegetables release their juices as they cook.

How many vitamins, minerals and how much fiber this food carries per calorie. A high score means a lot of nutrition for few calories.
Medium
An EatBetter score computed from fiber, protein and calorie density. A high score means staying full longer on the same calories.
Both scores are calculated per 100 g and do not change with the selected portion. The satiety score is EatBetter's own calculation, not a clinical measure.
