I cooked and served my seafood udon noodle soup directly in a shallow donabe (Japanese earthern claypot). It definitely helps the dish to look more attractive :p

Assorted Seafood (For One Pax)

Assorted seafood pack for one pax. I vacuumed sealed a few of these lonely WFH-friendly packs for the freezer. Whenever needed, just thaw the pack for cooking. My seafood pack consists of asari clams, tiger prawn and a shell-on scallop. With this preparation beforehand, I can enjoy a variety of seafood anytime, even though I am cooking for only one or two persons.

Rest of the ingredients. Napa cabbage, shiitake & enoki mushrooms, scallion and fresh udon noodles. The lone tofu is a freeze-dried version which enables me to add 1-2 tofu cubes in my meal without buying a whole tofu block every time. I used about 1/3 packet of udon each time I cook, as I prefer to be full on ingredients and eat lesser carbs.



Seafood Udon Noodle Soup Base

I tried something new for the soup base with ready ingredients in my pantry. I used 2 spoons of pork (or chicken) ramen soup sauce, 1/4 bouillon cube and 2 slices of ginger. It turned out to be good!

Add water and bring the soup to a boil, making sure that the bouillon cube is fully dissolved.

Side note: I boiled the scallop and prawn for one minute in the soup base, because they couldn’t fit into my clay pot.

This recipe serves one (ideal solo or WFH lunch), but feel free to adjust the ingredients and the size of the claypot used to cook for more.

(A) Soup Base

Suggested Garnishes


  • Donabe or clay pot for one person can use any pot and dish out to a bowl if not available


  1. Prepare soup base by bringing (A) to a boil, making sure the soup cube is entirely dissolved. Season to taste.
  2. Prepare the donabe (clay pot) and cook. Line the base of the pot with napa cabbage. Arrange the rest of the ingredients on top of the cabbage. Pour prepared soup base into the pot, and cover with lid to simmer until the cabbage and mushrooms are cooked, about 3 minutes. Discard any clams which remained closed after cooking. Garnish with ramen egg & spring onions. Serve immediately.

Cooking Note(s):

  1. I made this pork ramen soup base as they are ready ingredients in my pantry. You can make dashi soup base, or an even simpler one made with instant soba sauce.
  2. To have variety in a bowl in a jiffy when cooking for one or two (ideal for those still working from home), I used the following:
  • single-pax assorted seafood pack (see pic) for the freezer: mine contains scallop, clams and prawn.
  • freeze-dried tofu (see pic) just soak in water, squeeze out excess water and it’s ready for cooking.
