Korean Food: 4 Cold Noodle Recipes Locals Swear By

Forget Naengmyeon: The Real Summer Noodles Koreans Actually Make at Home

Last time, I introduced you to the cold noodle royalty of Korea: Makguksu and Naengmyeon. Today, I'm pulling back the curtain on something different. This is Korean food on a whole other level — the stuff Koreans actually make in their own kitchens when the sun turns merciless and the last thing anyone wants to do is stand over a boiling pot for hours.

These dishes don't demand a broth simmered for half a day to build depth. They demand nothing but a blender, a few minutes, and your own taste buds. Today, I'm handing you four of Korea's real summer survival weapons.

1. The Creamy Protein Bomb: Kongguksu (Soybean Noodle Soup)

You can make a noodle dish as smooth as cream and as nutty as a good espresso, using nothing but a blender. Kongguksu is the protein source Koreans crave most when summer hits. And the method? Almost insultingly simple.

The basic method

First, you boil yellow soybeans that have been soaked in water. You strip away every last bit of skin. Then you toss those beans into a blender with water and grind them until smooth. What comes out is a thick, savory, unsweetened soy milk broth for noodles — nothing like the sweet soy milk you're picturing. Pour it over cooked thin wheat noodles (somyun), and you're done.

Garnish and seasoning

Top it with thin slices of cucumber. Season lightly with salt. That's it. That's the whole move.

The shortcut every local knows

Korean supermarkets have already solved this problem for you. Every summer, they stock cold, pre-made unsweetened soy milk broth in plastic bottles, sitting right there in the refrigerated section. All you have to do is boil your noodles and pour. No blender required. No excuses left.

2. Mom's Secret Recipe: 5-Minute Naengguksu (Cold Noodle Soup)

There's no fixed formula for Naengguksu. Everyone has their own cold-noodle religion. Sometimes you'll even spot "Naengramyeon" — a chilled version of instant ramen — showing up in summer. But today, I'm giving you something better: the exact recipe my mother passed down to me.

The garnish, made in two minutes

Julienne some zucchini and onion. Throw them in a pan with cooking oil and a pinch of salt. Sauté lightly. That's your entire topping, finished.

Prepping the noodles

Boil thin wheat noodles (somyun). Rinse them under cold water until they're completely chilled. Set them aside.

The "magic broth" that isn't really magic

Building a proper noodle broth is usually the most time-consuming, labor-intensive part of the whole process. My mother's version breaks that rule entirely. For one serving, mix 350ml of cold water with two spoonfuls of Korean tuna liquid extract (a savory, umami-rich seasoning made from smoked tuna, closer to a concentrated dashi than Southeast Asian fish sauce). That's the entire broth. Adjust the amount to match your own taste.

A personal touch

My daughter hates onions, so she skips the garnish entirely. She just uses water and three spoonfuls of tuna liquid extract, and calls it a day.

You might doubt a dish this simple can actually taste good. Take one bite. No further explanation necessary.

3. The Spicy-Sweet Seduction: Bibimguksu (Spicy Mixed Noodles)

Do you want your taste buds slapped awake with something spicy and tangy? Bibimguksu is your answer. And once again, you're free to throw in whatever ingredients call to you.

The classic sauce

The most traditional formula combines chopped kimchi, gochujang (Korean chili paste), vinegar, and sugar. Mix these together with your cooked thin wheat noodles right in the bowl. Done.

Enter the world of Bibim Ramyeon

If even making a sauce sounds like too much effort, meet Korea's true soulmate: Bibim Ramyeon — instant spicy mixed noodles. Korean supermarkets carry a staggering number of brands, and newcomers are aggressively fighting for shelf space with big advertising budgets. But Paldo Bibim Myun, Korea's original bibim ramyeon, remains the undisputed standard that most Koreans still reach for first.

4. The Ultimate Refresher: Dongchimi Guksu (Radish Water Kimchi Noodles)

Last but not least: Dongchimi Guksu, built on Korea's traditional watery radish kimchi. If you remember the refreshing punch of Makguksu I described last time, this is the easiest way to recreate that exact sensation.

The method

Prepare well-fermented, ice-cold dongchimi (radish water kimchi) broth. Add cooked thin wheat noodles. That's the entire recipe.

The sharp, tangy chill of the dongchimi broth will drop your body temperature faster than any air conditioner in the room.
