Yaki Udon (Japanese Stir-Fried Udon Noodles)

Share this recipe!

There’s something about a plate of steaming stir-fried noodles that instantly feels like home. On busy weeknights, when I’m staring at the fridge wondering what to make, Yaki Udon has saved me more times than I can count. Thick, chewy noodles tossed with crisp vegetables, a bit of protein, and a savory sauce — it’s the kind of meal that’s quick enough for a Tuesday but tasty enough to serve to guests. I’ve made this for casual family dinners, packed it into lunch boxes, and even whipped it up for friends who popped by unexpectedly. It’s comfort food with a touch of Japanese street food charm.

Why You’ll Love This Yaki Udon

• Quick to make – You can get this on the table in under half an hour.
• Incredibly satisfying – Those chewy noodles and savory sauce hit the spot every time.
• Flexible ingredients – It’s perfect for using up leftover vegetables or whatever protein you’ve got in the fridge.
• Easy to adapt – Works just as well for meat lovers as it does for vegetarians or vegans.

A little personal note — my daughter adores udon noodles, so I keep a stash of frozen ones in the freezer. On nights when I’m tired but still want a hot, homemade meal, I can have this ready before she’s even finished setting the table.

Ingredients You’ll Need

• Udon Noodles – Fresh or frozen are best for that chewy texture.
• Protein – Sliced pork belly is my go-to, but chicken, beef, shrimp, or tofu work beautifully.
• Vegetables – I love using green cabbage, carrot, onion, green onions, and shiitake mushrooms, but feel free to mix it up.
• Neutral Oil – For stir-frying without overpowering the flavor.
• Seasoning Option A – Dashi powder, soy sauce, sake, and mirin (or a pinch of sugar).
• Seasoning Option B (my favorite) – Mentsuyu plus soy sauce for a rich, ready-in-seconds flavor.

Ingredient Tip: If you’re cooking for a vegetarian or vegan crowd, swap the dashi for kombu dashi powder and skip the pork. Fried tofu or tofu puffs add a great bite.

How to Make Yaki Udon at Home

Step 1 – Prep Your Ingredients

Slice the onion, carrot, and shiitake mushrooms. Cut the cabbage leaves into bite-sized pieces. Chop the pork belly into small pieces and the green onions into short lengths.

Step 2 – Blanch the Noodles

If you’re using frozen cooked udon, just drop them into boiling water for 30–40 seconds to loosen. Dried udon will need a few minutes more, so cook according to the package. Drain and set aside.

Step 3 – Stir-Fry the Protein and Veggies

Heat a large skillet or wok, cook the pork belly until it’s no longer pink, then toss in the vegetables. Cover and let them steam for about 3 minutes so they soften while keeping their crunch.

Step 4 – Add the Noodles and Sauce

Toss the noodles into the pan with your chosen seasonings. Use tongs to mix everything well — it’s so much easier than spatulas. Taste and adjust with salt or pepper if needed.

Step 5 – Serve and Garnish

Dish up onto plates and top with optional bonito flakes and pickled red ginger for that authentic touch.

My Best Cooking Tips

• Don’t overcook the noodles – Frozen udon is already cooked; it just needs heating through.
• Use a large pan or wok – More surface area means better stir-fry flavor.
• Steam the veggies – Covering them briefly helps soften them without losing color or crunch.
• Keep mentsuyu in the pantry – It’s a quick shortcut for flavor-packed sauces.
• Always have udon on hand – Frozen or dried noodles mean you’re never far from a satisfying meal.

Easy Variations

• Swap the protein – Chicken, beef, shrimp, mixed seafood, or tofu all work well.
• Change the vegetables – Bell peppers, bok choy, broccoli, or snap peas make great additions.
• Go fully plant-based – Extra veggies and fried tofu make a hearty vegetarian version.

What to Serve with Yaki Udon

While it’s filling on its own, I sometimes pair it with:

• Edamame for a simple starter.
• Japanese cucumber salad or spinach with sesame dressing for a fresh side.
• Agedashi tofu or gyoza for extra protein.
• Miso soup for a warm, comforting bowl alongside.

Storage

• Fridge – Store in an airtight container for up to 3–4 days.
• Freezer – Keeps for about a month. Reheat in a pan with a splash of water or broth to freshen it up.

Final Thoughts

Yaki Udon is one of those recipes that feels like a weeknight lifesaver and a special treat all at once. The chewy noodles, savory sauce, and mix of textures make every bite satisfying. It’s flexible enough to suit whatever’s in your fridge, and with just 25 minutes from start to finish, it’s faster than ordering takeout. Once you’ve made it a couple of times, it’ll become one of those “I can make this with my eyes closed” dishes — and you’ll be glad to have it in your back pocket.
