Instructions
Make the Pork Wontons
In a bowl, mix ground pork, green onion, ginger, soy sauce, sesame oil, sugar, and white pepper until well combined and slightly sticky.
Place about 1 tsp filling in the center of each wonton wrapper. Moisten edges with water, fold into a triangle, and pinch to seal. Optionally bring corners together to form a “boat” shape.
Set aside on a floured tray and cover with a damp towel to prevent drying.
Simmer the Broth
In a large pot, combine chicken broth, water, garlic, ginger, soy sauce, mirin, and sesame oil.
Bring to a boil, then reduce to a gentle simmer for 10–15 minutes. Taste and adjust seasoning. Remove garlic and ginger before serving.
Cook the Wontons & Udon
Bring a separate pot of water to a gentle boil. Cook wontons for 4–5 minutes, or until they float and are fully cooked. Remove with a slotted spoon.
Cook udon noodles in the same or separate pot according to package instructions (about 2–3 minutes for fresh or frozen). Drain and set aside.
Assemble the Bowls
Divide udon noodles among 4 bowls.
Top with 5–6 wontons per bowl.
Ladle hot broth over noodles and wontons.
Add a generous handful of spinach—let it wilt in the hot broth.
Finish with green onions and any optional toppings.
For the best flavour-packed wonton udon noodle soup, gently simmer the broth instead of boiling it hard—this keeps the ginger and garlic clean and aromatic rather than bitter. Cook wontons separately and add them at the end so they stay plump and intact, and always add spinach just before serving so it wilts perfectly into the hot broth without overcooking.
Notes
Add chili oil or a soft-boiled egg for extra richness and flavour.
Swap spinach for bok choy or napa cabbage if preferred.
Frozen wontons work perfectly for a quick, weeknight version.
To meal prep, freeze uncooked wontons on a tray, then store in a bag for later use.
