Sara Udon — Nagasaki Crispy Noodles with Thick Ankake Gravy
Sara udon (皿うどん) is one of Nagasaki’s great gifts to Japanese comfort food — a nest of thin, crackly fried noodles buried under a thick, glossy ankake gravy loaded with pork, seafood, and vegetables. The noodles soften just where the sauce touches them and stay crisp everywhere else, so every bite is part crunch, part slurp. Here in Kyushu it’s a genuine local favorite, and it’s exactly the kind of thing we make at home on a night when we want something a bit special without much fuss.
I’ll be honest: I used a supermarket sara udon kit (Marutai, a Fukuoka brand) for this one — the crispy noodles and the ankake soup base come in the pack, and you just add your own meat, seafood, and vegetables. That’s how most people actually make sara udon at home in Japan, and it’s genuinely good. Here’s how I put it together.

What is Sara Udon?
Sara udon literally means “plate udon,” though despite the name it’s usually made with thin, crisp-fried noodles rather than thick udon. It comes from Nagasaki and is a close cousin of champon — same idea of pork, seafood, and vegetables, but where champon is a noodle soup, sara udon piles the toppings as a thick ankake (starch-thickened) gravy over fried noodles. It’s Chinese-influenced Japanese food, born in Nagasaki’s port kitchens, and now a beloved staple all over Kyushu.

The easiest way in is a sara udon kit, which gives you the hard-to-find crispy noodles and a ready ankake base. After that it’s just a stir-fry, so a good frying pan is all the equipment you need. The beauty of sara udon is you can use whatever meat, seafood, and vegetables you have.
How to Make Sara Udon
Step 1: Gather Everything
Prep your meat, seafood, and vegetables so everything is ready — the stir-fry moves quickly. The kit gives you the crispy noodles and the ankake soup packets; the rest is up to you.
Step 2: Mix the Ankake Sauce
Whisk the ankake soup base with water according to the kit instructions. Mixing it smooth now means no lumps when it thickens in the pan later.
Step 3: Cut the Pork and Seafood
Cut the pork into bite-sized pieces and prep the seafood. I used a mix of scallops, shrimp, and squid, but any combination works.
Step 4: Stir-Fry the Meat and Vegetables
Heat the oil in a pan over medium-high heat. Start with the pork and firmer vegetables (carrot, onion), then add the cabbage and any quicker-cooking vegetables.
Add the seafood and fish cake and stir-fry until everything is just cooked through and the vegetables are tender-crisp.
Step 5: Add the Sauce and Thicken
Give the ankake mixture another stir, then pour it into the pan. Bring it to a simmer over medium heat, stirring, and let it cook until the sauce turns glossy and thick enough to coat the vegetables.
Keep simmering until it’s thick and glossy — it should mound on a spoon, not run off like soup.
Step 6: Pour Over the Noodles
Loosen the crispy noodles onto plates, then ladle the hot ankake gravy generously over the top. Serve right away, while the noodles still have their crunch — some people add a splash of Worcestershire sauce or vinegar at the table.
Tips and Variations
- Serve immediately. The noodles soften fast once the sauce is on, so plate and eat right away.
- Use what you have. Sara udon is forgiving — any mix of pork, seafood, and vegetables works.
- Add Worcestershire or vinegar. A splash at the table is the traditional Nagasaki finish.
- Don’t have a kit? Crisp-fried thin ramen noodles and a soy-based sauce thickened with potato starch get you close.
What to Serve It With
Sara udon is a full meal on its own, but a couple of light sides round it out:
- A crisp cold side like tataki ume kyuri or daikon salad.
- Gyoza on the side, diner-style.
- A cold beer — it’s that kind of dish.
Storing
Sara udon is best eaten fresh — once the sauce sits on the noodles they lose their crunch. If you have extra, store the ankake gravy and noodles separately: keep the gravy in the fridge for 1–2 days, reheat it, and pour over freshly loosened noodles. The gravy alone is also great over rice the next day.
Frequently Asked Questions
What is sara udon?
Sara udon (皿うどん) is a Nagasaki dish of crisp fried noodles topped with a thick, savory ankake sauce full of pork, seafood, and vegetables. Sara means plate — it’s served on a plate rather than in a bowl. Despite the name it doesn’t use udon noodles at all.
What noodles do I need?
The thin, crisp pre-fried noodles sold specifically for sara udon, found in Japanese groceries. There’s also a soft thick-noodle version of the dish. If you can’t find either, crisp chow mein noodles are the closest substitute.
What is ankake?
Ankake is a sauce thickened with potato starch slurry into a glossy, clinging consistency. It holds heat well and coats the noodles slowly, which is why the bottom layer softens while the top stays crisp — that contrast is the whole point of the dish.
How do I stop the sauce going lumpy?
Mix the potato starch with cold water into a smooth slurry, stir the sauce well, then pour the slurry in gradually while stirring, with the pan at a gentle simmer. Dumping starch straight in or adding it to a rolling boil is what makes lumps.
Should I pour the sauce over just before serving?
Yes, right at the table. The noodles start softening the moment the sauce lands, and eating it involves both crisp and softened noodles. Sauce poured too early gives you a plate of soggy noodles.
