A maguro Boston roll is made with sushi rice, nori and tuna; some versions also include avocado, cucumber or other fillings. The exact ingredients vary by restaurant, so check the menu if you need to avoid a particular ingredient.
Not always. A maguro Boston roll may contain raw, seared or cooked tuna, depending on the restaurant. Ask how the tuna is prepared if you want to avoid raw fish.
Maguro is the Japanese word for tuna. In a maguro Boston roll, it identifies the tuna filling, while “Boston roll” refers to a style of sushi roll rather than one fixed recipe.
A maguro Boston roll uses tuna as its defining filling. A traditional Boston roll is commonly made with cooked shrimp, though ingredients vary between restaurants; check the description rather than relying on the name alone.
Spread sushi rice over a sheet of nori, add tuna and any chosen fillings, then roll it tightly with a bamboo mat. Use a sharp, damp knife to slice it, and choose sushi-grade tuna if serving it raw.
The Boston roll is named for its association with Boston-style sushi in the United States. A maguro Boston roll is a tuna variation, but restaurants may use different fillings and the name does not guarantee a standard recipe.
Soy sauce, wasabi and pickled ginger are common accompaniments to a maguro Boston roll. Use soy sauce sparingly so it does not overpower the tuna, and dip the cut side lightly to keep the rice intact.
It is best to eat a maguro Boston roll the day it is made, especially if it contains raw tuna. Refrigerate leftovers promptly in a sealed container, and discard them if they have been left out or their smell or appearance has changed.
Freezing a maguro Boston roll is not recommended. Thawed sushi rice can turn dry or mushy, and fillings such as cucumber or avocado lose their texture; eat it fresh instead.
Avoid a maguro Boston roll made with raw tuna during pregnancy, and choose a fully cooked filling instead. Tuna limits depend on the type of fish, so ask your healthcare professional for advice suited to you.

A Maguro Boston roll is a sushi roll made with tuna, rice and nori. “Maguro” means tuna in Japanese, while the Boston roll is part of the American-style sushi tradition.
Soft, lightly seasoned rice contrasts with the nori’s subtle sea flavour and the tuna’s savoury taste. It is commonly served with soy sauce and wasabi; outside sushi restaurants, it can make a convenient light lunch or snack. Rice supplies most of its carbohydrates, while tuna contributes protein: a 100 g portion has 8.1 g. For a lighter meal, pair it with a simple salad rather than adding several rich sides.
