A comforting bowl of thick udon noodles in a savory dashi broth, topped with crispy tempura shrimp and vegetables. This recipe combines a light, umami-rich soup with perfectly fried tempura for a satisfying meal.
Prepare the broth: In a saucepan, combine dashi stock, soy sauce, mirin, sugar, and salt. Bring to a simmer over medium heat, then reduce to low and keep warm.
Cook udon noodles according to package directions. Drain and divide into two bowls.
Make tempura batter: In a bowl, whisk together flour, cornstarch, ice-cold water, and egg yolk until just combined (lumps are okay). Keep batter cold.
Heat oil in a deep pot to 350°F (175°C). Pat shrimp dry and lightly dust with extra flour. Dip shrimp into batter, letting excess drip off, and fry in batches until golden and crispy, about 2-3 minutes. Drain on paper towels.
Dip carrot slices and broccoli florets into batter and fry until crisp, about 1-2 minutes. Fry shiso leaves for 30 seconds if using.
Ladle hot broth over the noodles in each bowl. Arrange tempura shrimp and vegetables on top. Garnish with green onions and shichimi togarashi if desired. Serve immediately.
Tips
For best results, use ice-cold water and keep batter cold to ensure a light, crispy tempura.
Tempura is best served immediately; if needed, keep warm in a low oven (200°F) on a wire rack.
Substitute shrimp with chicken or vegetables for variation.
