Ingredients

1 bunch scallion
100 gram mushroom
60 gram kale
1/2 red chili pepper
100 gram bean sprouts
1 teaspoon dark soy sauce
2 tablespoon light soy sauce
1 teaspoon sesame oil
1 pinch sesame seeds
1 pinch crushed red pepper flakes
1 tablespoon olive oil
2 packages udon noodles

Instructions

Step 1: Cut the scallion into white and green parts, then slice them separately. Set aside.
Step 2: In a small bowl, mix dark soy sauce, light soy sauce, sesame oil, sesame seeds, and crushed red pepper flakes. Set aside.
Step 3: Heat olive oil in a large non-stick frying pan. Add the white parts of the scallion and fry for one minute until edges turn slightly golden.
Step 4: Add mushrooms, kale, and red chili pepper to the pan. Stir-fry for 4–5 minutes until vegetables are tender.
Step 5: Add the udon noodles to the pan.
Step 6: Pour the sauce mixture over the noodles and toss well so the sauce coats everything evenly. Cook for 3–4 minutes.
Step 7: Turn off the heat. Stir in the bean sprouts and green parts of the scallion, mixing for 30–40 seconds.
Step 8: Sprinkle extra sesame seeds on top and serve immediately.

Tips & Variations

For a protein boost, add sliced chicken, tofu, or shrimp during step 4.
Adjust the amount of chili pepper or crushed red pepper flakes to control the spice level.
Use fresh udon noodles for the best texture, or thaw frozen ones before cooking.
Try adding other vegetables like bell peppers or snap peas for extra color and crunch.

Storage

Store leftover stir-fried udon noodles in an airtight container in the refrigerator for up to 2 days. Reheat gently in a pan or microwave, adding a splash of water to prevent drying out.

FAQs

Can I use dried udon noodles instead of fresh?

Yes, but cook the dried udon noodles according to package instructions before stir-frying, as they require boiling to become tender.

How spicy is this dish?

This recipe has a mild to medium heat level due to the red chili pepper and crushed red pepper flakes, but you can adjust the spice to your preference by adding more or less.
