Servings and timing
- Servings: 2 bowls
- Prep time: 10 minutes
- Cook time: 15 minutes
- Total time: 25 minutes
Variations
- Vegetable tempura: Add battered shrimp alternatives like sweet potato, broccoli, or bell pepper for extra variety.
- Spicy twist: Add sliced chili or a few drops of sriracha.
- Protein swap: Use tempura chicken or tofu instead of shrimp.
- Broth boost: Stir in a teaspoon of miso paste for deeper richness.
- Noodle choice: Substitute soba or ramen noodles for a different texture.
Storage/Reheating
- Broth: Store leftover broth in the fridge (up to 3 days) or freezer (up to 1 month).

- Noodles: Store separately from broth; reheat in hot water briefly to refresh.

FAQs
1. Can I make the tempura batter ahead?
Yes—mix batter and keep covered and cold, but fry shrimp immediately for best crispiness.
2. What’s the best oil for frying?
Use a neutral high-smoke oil like canola or vegetable oil.
3. How do I know when oil is at 350 °F?
Use a fryer thermometer or test by dropping a little batter—if it sizzles and floats, it’s ready.
4. Can I use frozen shrimp?
Yes—thaw and pat them dry thoroughly before battering to prevent splatter.
5. Can I use instant dashi?
Absolutely—just follow packet instructions to make broth.
6. Why rinse udon after cooking?
Rinsing stops cooking and prevents noodles from sticking together.
7. Can I cook everything in advance?
Make the broth and noodles ahead, but cook tempura just before serving for optimal texture.
8. Is this gluten-free?
Use gluten-free tempura batter and tamari in place of soy sauce to adapt.
9. Why add radish slices?
They add a crisp, peppery freshness that contrasts with the rich broth.
10. Can I double the recipe?
Yes—adjust ingredient quantities and cook in larger batches for more servings.
