Super Spicy Cold Noodles Recipe

Combine rice vinegar, water, sugar, and salt in a jar or bowl and stir until sugar dissolves. Add thinly sliced red onion, press under liquid, cover, and chill at least 30 minutes (can be made ahead 1–2 days).

Cook noodles

Bring a large pot of salted water to a boil. Add ramen noodles and cook according to package until just tender (about 2–4 minutes for fresh, 3–5 minutes for dried). Drain and rinse under cold water until cool. Toss with a drizzle of neutral oil to prevent sticking. Chill in fridge while preparing other components.

Prepare katsu chicken (if using)

Pat chicken dry, season both sides with 1/2 tsp salt and 1/4 tsp pepper. Set up three shallow bowls: flour, beaten egg, and panko. Dredge each chicken breast in flour, shake off excess, dip in egg, then press into panko until well coated. Heat neutral oil in a skillet (or deep fryer) to 350°F (175°C). Fry chicken until golden and internal temp reaches 165°F (approx. 4–6 minutes per side depending on thickness). Drain on a rack or paper towel, rest 5 minutes, then slice into strips.

Prepare crispy tofu (alternative protein)

Press tofu for at least 20 minutes to remove moisture. Cut into slabs. Lightly season with 1/2 tsp salt. Dredge tofu in flour, then egg wash (or cornstarch slurry for vegan), then panko. Fry in 350°F (175°C) oil until golden and crisp, about 3–4 minutes per side. Drain on paper towel and keep warm or cool briefly if serving cold.

In a medium bowl, whisk together peanut butter, tahini, soy sauce, black vinegar (or rice vinegar), sesame oil, doubanjiang, Sichuan chili oil, toasted sesame seeds, sugar, grated ginger, minced garlic, five-spice (if using), and 1/4 tsp salt. Gradually whisk in warm water, 1–2 tablespoons at a time, until you reach a pourable, creamy consistency that clings to noodles (about 1/2 cup total). Taste and adjust heat with more chili oil or doubanjiang and seasoning with salt or a teaspoon more sugar if it needs balance.

If sauce thickens when chilled, thin with additional warm water or a splash of soy sauce before tossing with noodles.

Prepare vegetables: julienne cucumber, slice scallions on a bias, chop cilantro, and toss slaw mix with a pinch of salt and 1 tsp rice vinegar to lightly season. Chop roasted peanuts coarsely.

Divide chilled noodles among 4 bowls (about 3 oz noodles per serving).

Spoon 2–3 tablespoons of the Sichuan sesame-peanut sauce over each portion of noodles and toss gently to coat evenly. Add more sauce to taste (reserve extra in case guests want more).

Arrange protein: place 3–4 slices of katsu chicken or 3–4 crispy tofu slabs on top of each bowl.

Top with julienned cucumber, a small mound of slaw, pickled red onion (about 2 tablespoons), chopped scallions, cilantro, and a generous sprinkle of chopped roasted peanuts.

Finish with an extra drizzle of Sichuan chili oil for more heat, a squeeze of lime, and optional extra toasted sesame seeds or red pepper flakes. Serve immediately cold. Provide extra sauce and chili oil on the side for super spicy preference.
