• Toasted sesame seeds for garnish – A small touch that adds nutty flavor and visual appeal to your bowl.
• Optional: mustard paste – Lets you amp up the zing if you want an extra kick.
• Optional: white vinegar or apple cider vinegar – Helps adjust the acidity for a personalized taste.
• 4 cups water – Forms the base of the broth, ensuring it’s light and easy to chill.
• 150 g beef brisket – Infuses the broth with rich, savory notes, though it can be swapped for other options.
• 20 g onion, peeled – Adds subtle sweetness and depth to the broth without overpowering other flavors.
• 5 g green onion, white part – Contributes a mild oniony aroma that enhances the soup’s freshness.
• 10 whole black peppercorns – Brings a hint of spice for a well-rounded broth.
• 2 cups dongchimi (radish water kimchi) brine – The star for that tangy, fermented kick, making the soup truly authentic.
• 2 tablespoons white vinegar or apple cider vinegar – Boosts the sourness, helping to create that icy, refreshing effect.
• 1 tablespoon Korean or nashi pear juice (from grated pear strained) – Adds natural sweetness and ties the flavors together.

Special Dietary Options

• Vegan: Swap the 150 g beef brisket for mushrooms or tofu to keep it plant-based, and use a vegetable stock instead of beef for the broth.
• Gluten-free: Ensure the 200 g dried naengmyeon noodles are made from 100% buckwheat, as some varieties might contain wheat.
• Low-calorie: Opt for less of the 1 hard boiled egg or skip it, and reduce the sugar to lower the carbs while maintaining the dish’s freshness.

How to Prepare the Perfect Korean Naengmyeon Cold Noodle Soup: Step-by-Step Guide

Preparing the Broth

To start your mul naengmyeon, begin with the broth as it needs time to chill. Soak 150 g beef brisket in water for 10 minutes to draw out blood, then drain it. In a medium pot, add 4 cups water, the brisket, 20 g onion, 5 g green onion white part, and 10 whole black peppercorns.

Boiling and Simmering

Boil everything covered over high heat and skim off any scum that rises. Reduce the heat to medium-low and simmer for about 1 hour until the brisket is tender. Once done, strain the broth and let it cool for 30 minutes. Remove the meat, cool it, trim any fat, and thinly slice it for toppings.

Mixing the Broth

Combine the beef stock with 2 cups dongchimi brine. Add 2 tablespoons white vinegar or apple cider vinegar, 1 tablespoon pear juice, 1 1/2 tablespoons fine sugar, 1/2 teaspoon fine sea salt, and 1/4 teaspoon mustard powder. Mix well and adjust the seasoning to your taste. Cover and freeze it lightly for 3-4 hours until it’s icy and slushy, or freeze overnight and thaw before serving.

Cooking the Noodles

Boil 200 g dried naengmyeon noodles according to the package instructions until they’re bouncy. Drain them and rinse under cold running water multiple times, adding ice if possible, to make them refreshing. Drain quickly and portion into bowls.

Assembling and Serving

Pour the chilled broth over the noodles in each bowl. Top with the sliced beef, 40 g pickled radish, 40 g julienned cucumber, 50 g sliced pear, and 1 halved hard-boiled egg. Sprinkle toasted sesame seeds on top and serve immediately with optional mustard paste and vinegar. This process takes about 1 hour 25 minutes total, including prep, cooking, and freezing, making it a breeze for busy schedules. As noted in external resources like Maangchi’s naengmyeon recipe, chilling is key for the best flavor.

Dietary Substitutions to Customize Your Korean Naengmyeon Cold Noodle Soup

Protein and Main Component Alternatives

If beef isn’t your thing, swap the 150 g beef brisket for tofu or seitan to keep things vegetarian. For a lighter option, use mushrooms instead, which add an earthy flavor without the heaviness. These changes make the soup adaptable for different tastes or availability.

Vegetable, Sauce, and Seasoning Modifications

Swap the 40 g cucumber for zucchini if it’s in season, or use kale for added nutrients in your toppings. For the sauce, reduce the 2 tablespoons vinegar if you prefer less tang, or add more 1/4 teaspoon mustard powder for extra spice. This lets you tailor the dish to seasonal finds or dietary limits, like low-sodium versions by cutting back on salt.
