Total Time 15 mins


Homemade Dashi

Garnish & Topping

  • 1 stalk green onion , thinly sliced
  • Large eggs (optional)



  • Prepare Ingredients:
    Shrimp: We used 16/20 headless tiger prawns. Peel and devein the shrimp.
    *Pro Tip: Don't throw away the shrimp shells! We'll add them to the dashi to give the broth a little extra flavor boost.
    Dashi Stock:
    For Homemade Dashi: make dashi stock with this dashi recipe
    For Instant Dashi: Mix 6g dashi powder (HonDashi) with 4 cups (1L) of water.

  • Cook Shrimp in Dashi: Bring the dashi stock to a bare simmer. Cook the shrimp in dashi stock until they're fully cooked. Set aside the shrimp once they're fully cooked.
    *Note: 16/20 extra-jumbo shrimp take roughly 4 to 5 minutes to cook in the dashi.
    *When to Add Shrimp Shells:
    If Using Homemade Dashi: Add in shrimp shells with kombu.
    If Using Instant Dashi: Add in shrimp shells with shrimp.

  • Cook Soft Boiled Eggs: Bring 7 cups (1750ml) of cold water to a full boil in a pot. Boil the eggs in boiling water for 5.5 to 6 minutes. Drain & place eggs in ice-cold water to stop the residual heat from further cooking them.

  • Season Dashi Broth: Add 2 to 2½ tbsp (30ml - 37.5ml) Japanese soy sauce to your dashi broth. Please don't add them all at once! Mix and bring your soy sauce dashi broth to a full boil.
    *Note: If you're using the Instant Pot, use the "Saute" button.
    *Pro Tip: Aim to have a slightly more salty dashi broth because the udon noodles will dilute the saltiness a bit. If you're using Instant dashi, use less soy sauce. Please taste and adjust accordingly.

  • Cook Frozen Udon: Place the frozen udon noodles in your pot of boiling water. Cook for roughly 40 seconds to 1 minute. Once cooked, remove udon from the water immediately. Drain well and place udon in a serving bowl.
