Tempura Veggie Bowl with Sushi Rice and Tentsuyu Sauce

A tempura vegetable bowl brings the crisp, delicate texture of Japanese tempura into a complete rice-based dinner. Thin rounds of sweet potato, courgette batons and tenderstem broccoli give a mix of sweetness, freshness and tender bite, while steamed sushi rice makes the dish satisfying without weighing it down. The tentsuyu — a light dipping sauce of dashi, soy sauce and mirin — adds savoury depth, and grated daikon cuts through the fried coating with clean, peppery freshness. Best served straight after frying, it suits a relaxed dinner where the vegetables stay hot, pale golden and brittle-crisp.

Why this recipe works

  • Light, crisp coating: Ice-cold sparkling water and minimal mixing help create a delicate batter that fries up crisp rather than dense.
  • Umami-rich sauce: Dashi, soy sauce and mirin give the tentsuyu a clean savoury-sweet balance that complements the fried vegetables.
  • Balanced bowl format: Seasoned rice makes the tempura more substantial, while grated daikon keeps each bite fresh and cuts through the richness.

Texture tips

  • Keep the batter lumpy: Stop mixing as soon as the flour is moistened; a slightly uneven batter gives tempura its light, irregular crust.
  • Serve the sauce separately: Dip the tempura into the tentsuyu at the table or spoon over only just before eating to preserve the crisp coating.
  • Fry in small batches: Adding too many vegetables at once cools the oil and leads to a heavier, oilier finish.

Ingredient notes

  • Best vegetables for tempura: Thin sweet potato slices, courgette batons and tenderstem broccoli cook quickly and offer a good mix of soft, crisp and tender textures.
  • About dashi powder: Many dashi powders contain fish, so choose a vegetarian version if you want the whole bowl to remain vegetarian.
  • Use daikon for freshness: Grated daikon is mild, juicy and peppery, helping to lighten the fried vegetables and savoury dipping sauce.

Common mistakes

  • Letting the oil temperature drop: Give the oil time to recover between batches so the batter sets quickly and stays crisp.
  • Making the batter too smooth: A smooth batter usually means too much gluten development, which can make the coating tough rather than delicate.
  • Cooking the tempura too early: Tempura is at its best immediately after frying, so have the rice, sauce and daikon ready before you start.

Make-ahead tips

  • Make the sauce in advance: The tentsuyu can be prepared ahead and gently warmed before serving.
  • Prepare the vegetables early: Slice the vegetables and grate the daikon before frying so the final cooking stage moves quickly.
  • Re-crisp leftovers carefully: Tempura is best fresh, but leftovers can be reheated on a baking tray at 220°C (430°F) until hot and crisp again.

  1. Rinse the rice in cold water until the water runs mostly clear, then drain well. Cook it in a saucepan with 360 ml water: bring to the boil, cover, reduce to low and cook for 12 minutes, then rest off the heat for 10 minutes. Stir through the rice vinegar and keep covered while you cook the tempura.
  2. Make the tentsuyu: in a small saucepan, whisk the dashi powder with 200 ml water, then add the soy sauce and mirin. Bring just to a gentle simmer for 1 minute, then take off the heat. Pour into a small bowl for dipping.
  3. Prepare the vegetables: peel the sweet potato and slice into thin rounds (about 3 mm). Cut the courgette into batons, and trim the broccoli into long, bite-sized pieces. Grate the daikon and set aside for serving.
  4. Heat the vegetable oil in a large pot to 175°C (350°F). Put the plain flour in a mixing bowl and whisk in the ice-cold sparkling water until just combined; it should be lumpy, not smooth. Keep the batter cold and do not overmix.
  5. Working in batches, dip the vegetables into the batter, let the excess drip off, then fry for 2 to 4 minutes until pale golden and crisp. Turn as needed and lift out with tongs, letting excess oil drain back into the pot. Keep the oil close to 175°C (350°F) between batches for the lightest coating.
  6. Divide the rice between two bowls and top with the tempura vegetables. Add a small mound of grated daikon to each bowl. Serve with the warm tentsuyu for dipping or spooning over.

Recipe notes

Tips

  • For the crispest tempura, keep the sparkling water very cold and mix the batter only until the flour is just moistened.
  • Fry in small batches so the oil temperature does not drop, and let the oil return to 175°C (350°F) before adding the next batch.
  • If you are pregnant, elderly, or immunocompromised, choose a vegetarian dashi powder that does not contain fish.

Substitutions

  • Replace Courgette with Broccoli for an all-broccoli tempura bowl; keep the total vegetable amount similar so the batter quantity still works.
  • Replace Rice vinegar with Mirin for a slightly sweeter rice seasoning, using the same amount.

Storage

  • Refrigerate up to 2 days
  • Store rice and sauce in separate airtight containers in the fridge for up to 2 days. Tempura is best eaten straight away; if you must keep it, refrigerate and reheat on a baking tray at 220°C (430°F) for 8 to 10 minutes until hot and re-crisped.
