Make authentic shiitake mushroom tempura at home! This easy recipe gives you light, crispy tempura every time, making it perfect as a side dish, snack, or appetizer.
Prepare the Shiitake: Remove the stems from the caps and trim off the tough stem tips.
Make the Batter: In a bowl, lightly beat the egg. Add cold water and flour, then gently mix until just combined (a few lumps are fine).
Fry the Tempura: Heat oil in a frying pan to 170°C (340°F). Lightly dust the shiitake with flour, dip them into the batter, and carefully place them into the hot oil. Fry until crisp, then transfer to a wire rack or paper towels to drain excess oil.
Serve: Arrange the tempura on a plate. Prepare the dipping sauce by diluting mentsuyu with water as directed on the bottle. Dip the tempura and enjoy right away while it’s hot and crispy!
Notes
Shiitake stems are edible and delicious when fried. Just trim off the tough tips and fry them along with the caps.
Mix the batter lightly and leave some lumps. Overmixing develops gluten, which makes the tempura heavy and chewy.
Lightly coat the shiitake with flour before dipping into the batter. This helps the batter stick better and prevents the coating from slipping off during frying.
