Korean Spicy Cold Noodles Ingredients
For the Noodles

For the Sauce
• Gochujang – Essential Korean chili paste that adds the perfect heat and depth to the sauce.
• Gochugaru – Korean red pepper flakes that enhance flavor and deliver an extra kick to your Korean Spicy Cold Noodles.
• Soy Sauce – Offers saltiness and umami; consider using gluten-free soy sauce as a substitution if needed.
• Sesame Oil – Imparts a rich, nutty aroma; olive oil can be used for a lighter touch.
• Rice Vinegar – Balances the richness of the sauce; substitute with apple cider vinegar if desired.
• Garlic – Freshly minced for a potent flavor; pre-minced or powdered garlic can work in a pinch.
• Honey – Adds a touch of sweetness to the sauce; for vegan options, you can swap with maple syrup.
For the Garnish
• Thinly Sliced Cucumber – Provides a refreshing crunch; radishes can be used as a fun alternative.
• Soft-Boiled Egg – Adds protein and a creamy texture; can be omitted for vegan-friendly preparations.

Step‑by‑Step Instructions for Korean Spicy Cold Noodles
Step 1: Make the Sauce
In a medium bowl, combine 3 tablespoons of gochujang, 1 tablespoon of gochugaru, 2 tablespoons of soy sauce, 1 tablespoon of sesame oil, 1 tablespoon of rice vinegar, 1 minced garlic clove, and 1 tablespoon of honey. Stir the mixture well until smooth and homogenous, ensuring there are no clumps of gochujang. Set this vibrant gochujang sauce aside while you prepare the noodles.
Step 2: Cook the Noodles
Bring a large pot of water to a rolling boil over high heat. Add the somyeon noodles and cook according to the package instructions, usually around 4-6 minutes, until they become tender yet firm (al dente). Once cooked, drain the noodles and immediately rinse them under cold water, using your fingers to separate them gently. This step cools the noodles down quickly, making them perfect for your Korean Spicy Cold Noodles.
Step 3: Combine Ingredients
In a large mixing bowl, add the chilled somyeon noodles you just prepared. Drizzle the gochujang sauce over the noodles and toss them thoroughly with tongs or your hands. Ensure the noodles are evenly coated with the vibrant sauce, turning them a glossy red color. This mixing process infuses the noodles with the delightful heat and sweetness of the sauce.
Step 4: Serve
Divide the sauced noodles into serving bowls. Garnish each bowl with thinly sliced cucumber, a soft-boiled egg (if using), a sprinkle of toasted sesame seeds, and a dollop of kimchi for an extra flavor punch. Serve immediately and enjoy your refreshing bowl of Korean Spicy Cold Noodles, best enjoyed cold to highlight their vibrant flavors.

Serve chilled for the best experience!
What if my gochujang sauce is too spicy?
No worries at all! If you find your gochujang sauce is a bit too spicy for your taste, simply reduce the amount of gochujang in the recipe. Start with 1 tablespoon, taste it, and gradually add more until you reach your desired heat level. Sweetening it with a bit more honey or maple syrup can also help balance the spice!
Are there any dietary considerations for this recipe, especially for allergies?
This recipe is quite adaptable! If you have a soy allergy, you can substitute the soy sauce with coconut aminos or a homemade sauce using tamari. For a vegan alternative, you can omit the soft-boiled egg or substitute it with silken tofu or additional veggies.
