natto cheese toast

Notoriously aromatic and slimy, natto is a fermented soybean product that people either love or abhor. Its many purported health benefits include reduced blood pressure and risk of heart disease and improved gut health.

Natto is packaged in 2-ounce containers that are sold in sets of three. Each container comes with two seasoning packets — a sauce of shoyu, mirin, and dashi and Japanese mustard. Most natto consumers use both packets. 

Typically eaten on hot rice, natto is equally appetizing on toast.


  • 2 slices bread
  • 1 package natto
  • 1/4 cup shredded Monterey jack cheese
  • Kewpie mayonnaise (optional)
  • Chopped green onion or kimchi, shichimi togarashi, or furikake to garnish

Toast bread until golden and place on a baking sheet. Using chopsticks or a fork, mix natto vigorously with seasoning packets until frothy. Spread evenly on bread slices and sprinkle with cheese. Broil in oven just until cheese melts, about 2 minutes. Drizzle with mayonnaise and garnish as desired. Makes 2 servings.
