When you press that tofu for a full thirty minutes, you’re not just removing water – you’re creating crispy edges and a tender interior. I marinate the cubes in soy sauce and sriracha, which seasons them deeply while the acid starts breaking down the surface. Then I bake at 350 degrees until the edges turn golden and slightly crispy. Press your tofu thoroughly for the best results – rushing this step means soggy tofu that won’t satisfy. When you bite into these cubes, you’ll get that satisfying crunch combined with a tender interior, plus all those savory flavors locked inside. For best results, invest in a quality tofu press* to ensure even water removal and consistent texture throughout your block.

Ingredients
- 8 oz firm tofu, pressed 30 minutes and cut into 3/4-inch cubes
- 1 tablespoon vegetable oil (for tofu)
- 2 tablespoons soy sauce (for marinade)
- 1 tablespoon sriracha (or 1.5 teaspoons for medium heat)
- 1 tablespoon rice wine vinegar (for marinade)
- 1 tablespoon cornstarch
- 9.5 oz (1 package) fresh or frozen udon noodles
- 1 bunch broccolini (about 8 oz), cut into 2-inch pieces
- 3 tablespoons vegetable oil (for stir-fry)
- 2 tablespoons sesame oil, divided
- 1 tablespoon peeled fresh ginger, minced
- 2 garlic cloves, minced
- 2 tablespoons soy sauce (for sauce)

- 1 bunch radishes (about 8-10), thinly sliced
- 1/3 cup roasted cashews
- 3 scallions, thinly sliced
Instructions
- 1Press tofu 30 minutes, then cut into 3/4-inch cubes. In a bowl, toss tofu with soy sauce, sriracha, 1 tablespoon rice wine vinegar, 1 tablespoon sesame oil, and cornstarch until evenly coated. Spread on a parchment-lined baking sheet and bake at 400°F (200°C) for 25-30 minutes, flipping halfway, until golden and crispy.
- 2Cook udon noodles according to package directions (2-3 minutes for fresh, 4-5 minutes for frozen). Drain and toss with 1 teaspoon sesame oil to prevent sticking. Set aside.
- 3Blanch broccolini in boiling salted water for 2 minutes until bright green and just tender. Drain and set aside.
- 4Heat vegetable oil in a large wok or skillet over high heat. Add garlic and ginger, stir-fry 30 seconds. Add broccolini and cook 2 minutes. Add 2 tablespoons soy sauce and 2 tablespoons rice wine vinegar, toss to combine.
- 5Add cooked udon noodles to the wok and toss everything together over high heat for 1-2 minutes. Remove from heat. Stir in remaining 2 teaspoons sesame oil.
- 6Divide noodles into bowls. Top with crispy tofu, sliced radishes, and cashews. Garnish with scallions and 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.
When shopping for these ingredients, grab firm tofu rather than silken varieties, as it holds its shape better during the pressing and baking process. To achieve the best results, invest in a stainless steel tofu press* for efficient water removal before cooking. Quality sesame oil and fresh ginger will boost the final dish’s flavor profile. The sriracha level can be adjusted based on personal heat preference, and fresh broccolini should be vibrant green without yellowing. Consider purchasing pre-sliced radishes if time is limited, and raw cashews can be swapped for roasted if preferred for added depth of flavor.
Marinating Tofu For Maximum Flavor

To begin preparing Spicy Udon With Crispy Tofu & Cashews, start by draining your 8 ounces of firm tofu. Cut the tofu into slices and place them on paper towels, then cover with additional paper towels and let stand for 30 minutes, pressing down occasionally to remove excess moisture. Once thoroughly drained, remove the paper towels and cut the tofu into cubes. Getting the tofu really dry is key for getting that crispy texture that makes this dish so good.
Preheat your oven to 350 degrees Fahrenheit and begin preparing the marinade. Combine 2 tablespoons of vegetable oil with 2 tablespoons of soy sauce and 1.5 teaspoons of sriracha, whisking them together until well incorporated. Add your tofu cubes to this mixture and let them stand for 15 minutes, allowing the flavors to soak in. After marinating, remove the tofu while reserving the marinade – this liquid will be used as the base for your final sauce.
Place the marinated tofu on a foil-lined baking sheet coated with cooking spray and bake for 10 minutes or until lightly golden. While the tofu crisps in the oven, cook your 1 packet of udon noodles according to package directions, then drain and rinse with cold water. Blanch 1 bunch of broccolini in salted boiling water for 3 minutes, remove to an ice bath, and chop. Once the tofu is ready, combine the reserved marinade with the remaining 1 tablespoon of vegetable oil, 2 tablespoons of sesame oil, 1 teaspoon of sesame oil, remaining 1/2 teaspoon of sriracha, 3 tablespoons of rice wine vinegar, and 1 tablespoon of peeled, chopped ginger. Toss together the baked tofu, noodles, broccolini, and 1 bunch of sliced radishes in this marinade, top with 1 handful of cashews, and serve.
Try Cashew Butter Instead
If you’d like a richer, more indulgent version of this dish, you can swap the whole cashews for cashew butter, which will coat your noodles in a creamy sauce that brings all the flavors together. Stir two to three tablespoons of cashew butter into your finished bowl, mixing thoroughly so it spreads evenly throughout. The butter creates a luxurious texture that works well with the crispy tofu and tones down the sriracha’s heat. You can thin it with a splash of sesame oil if it’s too thick. This version delivers restaurant-quality results while keeping prep time minimal.
Pair With Jasmine Iced Tea
Since this spicy udon dish has bold, warming flavors from the sriracha and ginger, you’ll want a drink that works with those tastes instead of fighting them, and jasmine iced tea does exactly that. The floral notes in jasmine won’t take over your meal but instead give you a nice break from the heat. I recommend brewing strong jasmine tea, then chilling it completely before serving alongside your noodles. The tea’s delicate sweetness calms your mouth between bites, while its subtle complexity brings out the dish’s aromatic qualities without clashing with the sesame oil or tofu’s earthiness. It’s the perfect pairing for this restaurant-quality meal.
Final Thoughts
With jasmine iced tea on the side, you’ve now got all the knowledge you need to pull together an impressive meal that balances crispy textures with bold, complex flavors. This dish works because you’re pressing the tofu to remove moisture, which lets it crisp up beautifully in the oven instead of steaming. The marinade’s acidity cuts through richness, while the cashews add satisfying crunch.
