Easy Kimchi Bibimguksu Instructions:
Boil somyeon according to package instructions. Rinse well under cold water to stop the cooking and remove excess starch. Drain thoroughly.
Air fry eggs at 300°F (150°C) for about 12 minutes. Transfer immediately to an ice bath for easy peeling.
In a large mixing bowl, mix together gochujang, rice vinegar, soy sauce, sugar, kimchi juice, sesame oil, water, garlic, and gochugaru until smooth.
Add the cooled noodles to the sauce and toss until evenly coated.
Chop the kimchi (a trick: use kitchen scissors inside a glass to avoid staining your cutting board). Slice cucumbers thinly.
Add the sauced noodles to a bowl. Top with chopped kimchi, cucumber slices, halved soft-boiled eggs, and a sprinkle of sesame seeds.
Storage Tips
Store bibiguksu in an airtight container in the fridge for up to one day. It is best to eat it fresh.
Substitutes
Somyeon → Substitute with angel hair pasta or Japanese somen noodles. While the texture will be slightly different, they work well in a pinch.
Rice Vinegar → Apple cider vinegar or white vinegar can be used instead.
Soy Sauce → Tamari is a great gluten-free alternative.
Cooking Tips
Rinse the noodles thoroughly under cold water to stop the cooking process and wash away excess starch. This helps prevent them from becoming clumpy.
Adjust the sauce to suit your taste: add more sugar for sweetness, extra kimchi juice for a tangy kick, or a splash of sesame oil for a richer, nuttier flavor.
Serve well chilled—I like to toss in a few ice cubes for an extra refreshing touch.
Frequently Asked Questions
Are these noodles very spicy?
The spice level is moderate, but it is easy to adjust. Reduce or remove the gochugaru for a milder version, or add more if you prefer extra heat.
Can I add protein?
Absolutely. Shredded chicken, canned tuna, grilled beef, shrimp, tofu, or a soft-boiled egg are all great additions.
Can I serve these noodles warm?
They are traditionally served cold, but you can enjoy them at room temperature or slightly warm.
Common Mistakes
Not rinsing the noodles properly: You need to rinse the noodles to remove the excess starch, or the noodles will become too gummy.
Not chilling ingredients. This dish tastes best cold because it is refreshing.
