Bibim Guksu (Korean Spicy Cold Noodles) Recipe

If you love bold flavors and dishes that are quick to pull together, this is the noodle bowl you’ll crave again and again.

Ingredients You’ll Need

You’ll only need a handful of simple, everyday ingredients to whip up Bibim Guksu (Korean Spicy Cold Noodles). Each one plays a key role in building that signature flavor and texture—don’t worry, if you’re missing something, I’ll share swaps and tips below!

• Somyeon (thin wheat noodles): These Korean-style noodles are quick-cooking and deliver the perfect soft-but-chewy bite.
• Fermented kimchi + brine: Adds a deep, tangy flavor and lots of crunch—don’t toss that brine, it’s the secret to bright sauce!
• Gochujang (Korean chili paste): The heart of the sauce—choose extra spicy if you dare, or mild if you’re heat-sensitive.
• Fine gochugaru (Korean chili flakes): Gives the sauce bold color and a layer of roasty heat you can’t get anywhere else.
• Sugar (any kind): Just a touch to balance all that spice and acidity. White sugar is classic, but you can use brown or raw if you wish.
• Plum vinegar (or rice vinegar): Plum vinegar shines in this sauce with an extra burst of fruitiness, but rice vinegar is just as tasty.
• Sesame oil: A drizzle of this nutty oil ties the whole dish together with a gorgeously fragrant punch.
• Soy sauce: Adds depth and savoriness—Korean soy sauce is ideal, but any light soy works.
• Fresh garlic: Finely grated or minced, it bloomed right in the sauce for a zesty kick (leave this out if making ahead for later).
• Crushed sesame seeds: A sprinkle on top and in the sauce for rich, toasty flavor and texture.
• Optional Toppings – Hard boiled egg, cucumber: These classic garnishes cool down the spice and add that perfect fresh crunch.

Variations

Bibim Guksu is happiness in a bowl, and it begs to be customized! Whether you need it vegan, gluten-free, or are just raiding your fridge for fun textures, there’s a tweak for everyone.

• Make it vegan: Leave out the egg and double down on crunchy cucumbers, carrots, or even julienned radish for extra bite.
• No kimchi? No worries—simply add another splash of soy sauce and pump up the vinegar for that classic tang.
• Add protein: Top your bowl with poached or shredded chicken, tofu, or even canned tuna to turn it into a satisfying meal.
• Swap the noodles: Try soba, rice noodles, or even spaghetti—they’ll all work with this flavor-packed sauce.
• Lower the heat: Omit the gochugaru or use a mild gochujang for a gentler, kid-friendly version of Bibim Guksu (Korean Spicy Cold Noodles).

How to Make Bibim Guksu (Korean Spicy Cold Noodles)

Step 1: Grind & Prep the Sesame Seeds and Toppings

Start by grinding your toasted sesame seeds until about half of them turn powdery—you want a mix of sesame “dust” and crunchy bits. Slice your cucumber into thin matchsticks for extra crunch, and boil your eggs to your preferred doneness if you’re using them as a topping.

Step 2: Mix the Sauce

Combine the kimchi brine, gochujang, gochugaru, soy sauce, sesame oil, vinegar, half of the crushed sesame, sugar, and garlic in a bowl. Stir until the sauce reaches a smooth, glossy consistency. If you’re prepping ahead, skip the garlic and sesame oil for now—they taste best when added right before serving.

Step 3: Stir in the Kimchi

Once your sauce is perfectly blended, stir in the chopped kimchi. This adds both vibrant texture and a fermented, punchy flavor that makes Bibim Guksu (Korean Spicy Cold Noodles) truly sing.

Step 4: Boil and Cool the Noodles

Bring a pot of water to a rapid boil and add your somyeon noodles. They cook lightning fast—just 3 to 3½ minutes! As soon as they hit perfect tenderness, strain and rinse them under icy water, rubbing gently to wash away starch. Trust me, extra rinsing keeps your noodles delightfully bouncy, never sticky.

Step 5: Dress and Toss

Add the noodles and sauce to a mixing bowl and toss until evenly coated. The vibrant red sauce clings to each strand, promising flavor in every bite.

Step 6: Serve & Top

Divide the sauced noodles into serving bowls. Top generously with the sliced cucumbers, hard boiled egg halves, and a sprinkle of the reserved crushed sesame seeds. Dive in immediately for maximum flavor and refreshment!

Garnishes

The classic finish for Bibim Guksu is a tumble of icy cucumber, a hard-boiled egg cut in half, and an extra shower of crushed sesame seeds. If you want even more crunch or color, toss on thin strips of carrot, red radish, or scallions. A few extra kimchi pieces on top never hurt anyone, either!

Side Dishes

Pair your noodle bowl with crispy fried Korean dumplings (mandu) or a cool, simple banchan lineup—think pickled radish, sautéed spinach, and, of course, extra kimchi. Even just a bowl of cold barley tea alongside makes Bibim Guksu (Korean Spicy Cold Noodles) into a complete, satisfying meal.

Creative Ways to Present

For summer gatherings, serve these noodles mounded over a nest of crushed ice in a shallow bowl—guaranteed to keep things frosty. Individual portions look beautiful garnished with a swirl of cucumber, bright microgreens, or edible flowers. For a “build your own” bar, set out sauces, noodles, and all the toppings for guests to customize their own Bibim Guksu bowls.

Make Ahead and Storage

Storing Leftovers

If you have extra noodles, store them undressed in a sealed container in the fridge for up to 2 days. Keep any unused sauce separate—just mix together when you’re ready to eat for the freshest taste and texture.

Freezing

Freezing Bibim Guksu isn’t recommended, as the texture of the noodles and vegetables just isn’t the same after thawing. It’s a dish best enjoyed fresh, with every component crisp and snappy!

Reheating

Since Bibim Guksu (Korean Spicy Cold Noodles) is meant to be eaten cold, you don’t need to reheat it! If your noodles clump in the fridge, rinse them quickly with cold water to loosen and refresh before dressing with sauce.
