   Heat the pan

   Heat vegetable oil in a large frying pan or wok over a medium-high heat until shimmering, about 1 minute.

4. 4

   Stir-fry vegetables

   Add the bell peppers, carrots, broccoli and snap peas. Stir-fry for 4–5 minutes, until tender-crisp.

5. 5

   Toss with sauce

   Lower the heat to medium. Add the drained noodles and prepared sauce, then toss gently for 2–3 minutes until evenly coated.

6. 6

   Finish and serve

   Divide the hot noodles between bowls. Top with green onions, toasted sesame seeds and fresh coriander, then serve immediately.

What is veggie udon?

Udon are thick, chewy Japanese wheat noodles often served in soups or stir-fries. This version brings them together with a mix of crisp vegetables and a quick soy, sesame and ginger sauce.

The method combines familiar Asian-inspired flavours rather than representing one specific traditional dish. Cooking the noodles separately and adding them to the pan at the end helps keep their texture while they take on the sauce.

Nutrition and macros by portion

The nutrition label shows one serving as written: 450 calories, 12g protein, 60g carbs, 18g fat.

The udon and brown sugar provide most of the carbohydrates, while sesame oil contributes much of the fat. The noodles, vegetables and sesame seeds contribute some protein, though this is a vegetable-focused bowl; serve it with tofu or edamame if you would like a more substantial protein accompaniment.

Choosing the vegetables

Bell peppers: Mixed colours add a sweet, fresh flavour and make the panful varied. Slice them evenly so they cook at a similar pace.

Carrots and broccoli: Thinly sliced carrots and small florets are easier to stir-fry quickly. Keep the broccoli pieces fairly uniform for even cooking.

Snap peas: Add them with the other vegetables, but watch their texture; they are best tender with a little bite remaining.

Getting the sauce right

Sauce base: Soy sauce brings saltiness, while brown sugar softens its edge. Sesame oil adds a nutty note, and garlic and ginger give the mixture its aromatic flavour.

Chilli: The red chilli flakes are optional, so leave them out for a milder bowl or use them for a little heat. Whisk the sauce before adding it to distribute the sugar and seasonings.

Keeping the noodles chewy

Boiling: Fresh or frozen udon need only 2–3 minutes in boiling water here. Follow the timing in the recipe and stop when the noodles are tender but still chewy.

Finishing: Drain the noodles well and toss them with sesame oil to help prevent sticking. Once they go into the pan, toss gently for 2–3 minutes rather than letting them sit and catch.

Timing the stir-fry

Hot pan: Heat the vegetable oil until shimmering before adding the vegetables. Stir-fry them for 4–5 minutes, moving them around so they cook without becoming too soft.

Final toss: Add the noodles and sauce only after the vegetables are tender-crisp, then reduce the heat to medium. The final 2–3 minutes are enough to coat and warm everything together.

Serving the bowls

Finish each bowl with green onions, toasted sesame seeds and chopped fresh coriander for freshness and texture. A little extra sesame oil can be drizzled over the top if desired.

Serve the noodles straight away while they are hot and the vegetables still have some bite. The dish works well as a meal on its own or alongside a simple, lightly dressed salad.

Recipe notes & tips

• Slice the vegetables before you start cooking so they can go straight into the hot pan.
• Cut the broccoli florets into similar-sized pieces to help them cook evenly.
• Drain the udon thoroughly so excess water does not dilute the sauce.
• Taste the sauce before adding it and adjust the chilli to suit your preference.
• Keep the vegetables moving in the pan to encourage even cooking.
• Serve the finished noodles promptly for the best chewy texture.

Variations

• Add tofu: Stir-fry cubed firm tofu until golden, then set it aside and return it to the pan with the noodles.
• Use other vegetables: Swap in thinly sliced cabbage or mushrooms for some of the listed vegetables.
• Make it milder: Leave out the red chilli flakes.
• Add a citrus note: Finish the bowls with a squeeze of lime.
• Boost the crunch: Add extra toasted sesame seeds just before serving.

Common mistakes to avoid

• Overcooking the udon: It can turn soft in the final toss, so drain it while it is still chewy.
• Uneven vegetable pieces: They cook at different speeds; slice or cut them to a similar thickness.
• Crowding the pan: The vegetables may steam rather than stir-fry; use a large pan or wok and keep them moving.
• Adding wet noodles: Excess water can thin the sauce; drain the udon thoroughly first.
• Leaving the noodles in the pan too long: Toss only for 2–3 minutes after adding the sauce to preserve their texture.

How to store

Refrigerate leftovers in an airtight container and use within 3 days. Reheat in a frying pan over a medium heat, stirring until hot; add a small splash of water if the noodles seem dry.
