It tastes almost like spicy naengmyeon. If you’re a naengmyeon lover, you won’t want to miss today’s recipe.

Tomato Gochujang Bibim Guksu in 6 Easy Steps

Step 1: Blanch and Peel the Tomato

Score a shallow cross on the bottom of the tomato. Blanch it in boiling water for 90 seconds and the skin will peel right off. Peel the tomato and set it aside.

Step 2: Prepare the Toppings

Julienne the cucumber into thin strips. Boil the egg for 9 minutes, then cut it in half. Halve the cherry tomato as well.

Step 3: Make the Tomato Gochujang Sauce

This is the heart of the bibim guksu recipe. Cut the peeled tomato in half, add it to a blender along with garlic, gochujang, plum syrup, vinegar, soy sauce, and sugar, then blend until smooth. Taste and adjust to your liking.

Step 4: Cook and Rinse the Noodles

Bring water to a rolling boil and cook the buckwheat noodles according to the package directions. Once cooked, rinse several times under cold water, using your hands to wash off the starch. This is what gives spicy Korean cold noodles their satisfying chewy texture.

Step 5: Assemble the Bowl

Place the noodles in a bowl and pour the blended gochujang tomato noodles sauce generously over the top.

Step 6: Top and Serve

Arrange the boiled egg, julienned cucumber, and cherry tomato on top. Sprinkle with sesame seeds and drizzle with sesame oil. Give it a good mix before eating, one bite and you’ll be surprised at how this tastes like a premium version of gochujang bibim guksu! 🤤

🚫 Don’t Do This! or You’ll Ruin Your Gochujang Bibim Guksu

Mistake 1: The first time I made gochujang bibim guksu, I threw the tomato into the blender with the skin on. The sauce came out gritty with bits of skin in every bite. For this recipe, always peel the tomato first.

Mistake 2: Not rinsing the noodles enough. If you just drain the water and pour the sauce on, the noodles won’t be chewy. Rinsing under cold water while rubbing the noodles with your hands is the secret to that perfect spicy Korean cold noodles texture.

Mistake 3: Adding too much gochujang. When making this bibim guksu recipe, adding extra gochujang makes the sauce heavy and overpowering.

Mistake 4: Forgetting the sesame oil. That final drizzle of sesame oil is what completes the flavor balance of this gochujang tomato noodles dish.
