Message from Nami( Just One Cookbook®): “Chicken Karaage (Japanese Fried Chicken) is crispy on the outside and juicy and tender on the inside. With Hikari Miso's Shio Koji, it tastes even better with the additional umami flavor. If I could only recommend one shio koji recipe, this Karaage would be it!”

Prep Time 10 minutes
Cook Time 15 minutes
Total Time 25 minutes
Servings 4


  • 1 lb (450g) boneless chicken thigh with skin cut into 1 inch pieces
  • 4 tbsp. SHIO KOJI
  • 1 tsp. grated ginger
  • 1 tsp. crushed grated garlic
  • 1 tsp. soy sauce
  • ½ cup potato starch or corn starch
  • Vegetable/canola oil for deep frying
  • Lemon wedges to serve


  • Combine the chicken with Hikari Miso Shio Koji, ginger, garlic and soy sauce in a bowl or large plastic bag and marinate for at least 30 minutes (or up to 1 day).
  • Heat up a pot of cooking oil for deep-frying. Ideal temperature is about 320-335F (160-170C).
  • When the oil is almost ready, add the potato starch in the bowl or plastic bag with the chicken. Mix and coat the chicken with the starch.
  • Gently drop each piece of chicken into the pot and deep fry until golden brown.
  • When it’s done, transfer the chicken onto a plate lined with paper towels. Continue with a new batch to deep fry. Serve immediately with slices of lemon.

Quick Tip

  • Make sure to deep fry only a few pieces at a time so the oil temperature will not drop too low. If the oil temperature is too high, Shio Koji can be easily burn before the chicken is cooked through.
  • If you are not sure if the chicken is done, use a knife to cut the thickest piece of chicken and check inside.
