Spicy miso cucumber salad is a quick Japanese-style side dish that turns crisp cucumbers into a bold and refreshing recipe in just 5 minutes. The cucumbers are usually sliced, smashed, or cut into bite size pieces so the spicy miso dressing can cling well while the inside stays juicy and crunchy. A simple sauce made with miso paste, chili oil, sesame oil, rice vinegar, soy sauce, garlic, ginger, or a little sugar gives the salad a balanced mix of heat, tang, sweetness, and umami. Sesame seeds, green onion, shichimi, nori, or bonito flakes can add extra aroma and texture. The final cucumber salad is cool, spicy, and savory without needing cooking, making it easy to serve with rice bowls, noodles, grilled meat, tofu, gyoza, karaage, or other Japanese home-style meals.
