by veganpreps.com

Ingredients
- 1 (225 g / 8 oz) package udon noodles
- 4 tablespoons roasted peanut oil (or 3 tablespoons sesame oil + 1 tablespoon vegetable oil)
- 1 (340 g / 12 oz) package firm tofu, pressed and cut into 12 pieces
- 3/4 teaspoon kosher salt, divided
- 1/4 teaspoon freshly ground black pepper
- 1 (310 g / 11 oz) package Asian cooking greens or baby spinach
- 1 bunch scallions, thinly sliced on the diagonal
- 1/4 teaspoon red pepper flakes
- 3 tablespoons soy sauce
- 1/2 teaspoon sugar
Instructions
- 1Cook udon noodles according to package directions in well-salted boiling water. Reserve 240 ml (1 cup) of the cooking water before draining. Drain and set noodles aside.
- 2Pat tofu pieces dry with paper towels and season on all sides with 1/2 teaspoon salt and black pepper. Heat 2 tablespoons of the oil in a large non-stick skillet or wok over medium-high heat until shimmering. Add tofu in a single layer and sear undisturbed for 3-4 minutes per side until deep golden and crisp. Transfer to a plate.
- 3Add remaining 2 tablespoons oil to the same pan over medium heat. Add scallion whites and red pepper flakes and cook 1 minute. Add greens and toss with tongs for 1-2 minutes until just wilted.
- 4Add the drained noodles to the pan along with 180 ml (3/4 cup) of the reserved noodle water, soy sauce, sugar, and remaining 1/4 teaspoon salt. Toss everything together over medium heat for 1-2 minutes until the broth is absorbed and noodles are coated.
- 5Return crispy tofu to the pan and toss gently to combine. Divide into bowls and top with scallion greens. Serve immediately.
Notes
- Store leftovers in an airtight container in the fridge for up to 4 days.
- This recipe freezes well for up to 3 months. Thaw overnight in the fridge before reheating.
- Adjust seasoning to taste after reheating, as flavors can mellow during storage.
Use firm tofu instead of silken tofu, since it’ll keep its shape when you’re searing it and get that nice crispy outside you’re after. Choosing between peanut oil and the sesame oil mix will change how your dish tastes at the end – peanut oil gives you a more neutral flavor, while sesame oil brings more aromatic richness. Fresh Asian greens or baby spinach work fine depending on what you can find and what you like, though the cooking time might shift a bit depending on what type you pick.
Cook Udon Without Mushiness

Begin by cooking an 8-ounce package of udon noodles according to the package directions, being careful not to overcook them or they will become mushy. Once cooked, drain the noodles and reserve about 1/3 cup of the cooking water, which you’ll use later to make the broth for the dish.
While the noodles cook, heat 2 tablespoons of roasted peanut oil (or a mixture of 3 tablespoons sesame oil and 1 tablespoon vegetable oil) in a medium skillet over medium heat. Pat a 12-ounce package of firm tofu dry and season all over with kosher salt and freshly ground pepper. Add the tofu pieces to the skillet and sear until golden brown, about 2 minutes per side, then set aside and keep warm. Add 1 tablespoon of oil and an 11-ounce package of Asian cooking greens or baby spinach to the skillet, tossing until just wilted.
To finish the dish, add the scallions (from 1 bunch, thinly sliced diagonally), a large pinch of red pepper flakes, the remaining 1 tablespoon oil, 3 tablespoons soy sauce, and a pinch of sugar to the greens. Pour in the reserved cooking water and heat to make a broth. Divide the noodles and greens among 4 bowls and top each with three pieces of the seared tofu.
Try Different Asian Greens
While the recipe calls for Asian cooking greens or baby spinach, you can easily swap in other leafy vegetables to match your taste and what’s available at your market. Try bok choy, which wilts quickly and has a mild flavor. Gai lan offers a slightly bitter edge that pairs well with the soy sauce. Mustard greens bring peppery notes, while tatsoi provides tender leaves that cook in seconds. Even regular spinach works great if Asian varieties aren’t stocked nearby. The key is choosing greens that wilt easily, since you’re cooking them fast in the skillet. Whatever you pick, you’ll create a delicious, personalized bowl.
Pair With Pickled Ginger Slices
To bring a bright, tangy kick to your udon bowl, add pickled ginger slices on the side or right into the broth. The acidity cuts through the richness of the peanut oil and tofu, while the ginger’s warmth works well with the red pepper flakes. You can buy quality pickled ginger at any Asian market, or make your own by marinating thin ginger slices in rice vinegar and sugar. Layer a small handful into each bowl just before serving, letting the flavors blend with the hot broth. This addition makes your simple udon into something more interesting and hard to stop eating.
Final Thoughts
This easy udon recipe works because it builds flavor through simple, quality ingredients rather than complicated techniques. You’re combining crispy tofu, wilted greens, and chewy noodles in one bowl without fussy steps. The soy sauce and reserved cooking water create a light broth that ties everything together. You don’t need fancy equipment – just a skillet and a pot. Each component tastes good on its own, but together they’re better. You can prep the tofu while noodles cook, making this a genuinely quick weeknight dinner that feels intentional and satisfying.
