So, real talk: I have never given udon noodles a fair chance. Why? I don’t know! When it comes to creating a good noodle recipe, my mind always jumps to soba noodles or ramen noodles over udon noodles, and I don’t know why that is. But for this particular noodle recipe, I decided to give udon noodles the chance they so deserve. This udon with spicy peanut sauce is the definitive (and delicious!) quick dinner night recipe.
I actually developed a vegetarian udon recipe and a meat-based udon recipe. I have to say, I actually give the vegetarian udon recipe a star or two higher than the meaty counterpart. The finished product is just so spicy and and filled with peanutty goodness. My other favorite part of this udon recipe is the spicy peanut sauce AND the crunchy radish garnish which is just freshly sliced radishes and scallions tossed with a bit of sesame oil and flaky sea salt.

Ingredients for Vegetarian Udon Noodles with Spicy Peanut Sauce
16 ounces dry udon noodles
4 scallions, divided
2 stalks celery, with leaves
4 small radishes (I used French breakfast but red radishes or daikon radishes will be fine!)
⅓ cup creamy peanut butter
⅓ cup soy sauce
⅓ cup unseasoned rice vinegar
2 tablespoons, plus 2 teaspoons sesame oil, divided
2 teaspoons chili oil (more or less to taste, depending on spice preference)
1 teaspoon toasted sesame seeds
Salt to taste
More chili oil, optional
Prepare Ingredients: Bring a large pot of salted water to a boil and cook the udon according to package instructions. Drain and rinse well and set aside. Trim and thinly slice the scallions, keeping the white and light green parts separate from the dark green parts. Trim and thinly slice the radishes into rounds. Trim and thinly slice the celery on an angle. Roughly chop the celery leaves.
Prepare the Peanut Sauce: In a bowl, whisk the peanut butter, soy sauce, rice vinegar, 2 tablespoons sesame oil, and 2 teaspoons chili oil until smooth and creamy. Taste and adjust ingredients as necessary. Set aside.
Prepare the Soft-Boiled Eggs: Bring a small saucepan of water to a boil. Add the egg and cook for exactly 6 minutes. Drain and rinse the egg under cold water. Carefully peel and cut in half.
Prepare the Garnish: In a bowl, combine the dark green parts of the scallions with the radishes. Drizzle with two teaspoons sesame oil and toss to coat. Season with flaky sea salt and the toasted sesame seeds and toss. Set aside.
Finish the Udon Noodles: In a large bowl, combine the noodles with the white parts of the scallions, the sliced celery, and the roughly chopped celery leaves and toss to combine. Pour the spicy peanut sauce all over and toss to coat. Taste and season according to your tastes.
To Serve: Divide the udon noodles between bowls and pile the radish garnish on top of each bowl of noodles. Serve with a soft-boiled egg, a sprinkle of toasted sesame seeds, and a drizzle more of chili oil if desired. Enjoy!
