Why This Recipe Has a Cult Following
This dish’s popularity lies in its ingenious use of everyday staples—no specialty sauces required. Using just a handful of ingredients, it delivers layers of flavor and a unique texture in every bite. Cold noodles are tossed in a silky, spicy sauce made from peanut butter and kimchi, making it ideal for hot weather, but equally comforting any time you need a pick-me-up. Flexibility is key here: use whatever noodles you have on hand, any style of kimchi, and customize the heat and tang to taste.
Ingredients: Simple, Bold, and Adaptable
- Kosher salt (for the noodle water and to taste)
- Long noodles (such as spaghetti, linguine, soba, or ramen; about 1/2 pound or 225 grams for 2 large servings)
- Unsweetened peanut butter (1/3 cup; both creamy and crunchy varieties work)
- Kimchi (1 cup, chopped—divided, with brine reserved)
- Optional add-ins and toppings: sliced cucumbers, scallions, cilantro, crushed peanuts, sesame seeds, or chili oil for extra zing
Directions: How to Make Spicy Peanut Butter & Kimchi Noodles
- Cook the noodles.
Bring a large pot of salted water to a boil. Add your chosen noodles and cook until they’re just shy of done—think toothsome yet tender (al dente). Start tasting a few minutes before the recommended cooking time. Drain the noodles and rinse thoroughly under cold water to prevent further cooking and to achieve a cool, springy texture. Shake off excess water.
- Make the creamy spicy sauce.
While the noodles cook, blend together peanut butter and 1/2 cup chopped kimchi in a food processor or blender until mostly smooth. Add about 3 tablespoons of liquid (kimchi brine, water, or a mix—adjust for your preferred balance of spice and tang) and blend again until creamy. Season with salt to taste. Transfer the sauce to a large heatproof bowl.
- Toss and adjust.
Add the cooled, well-drained noodles to the sauce. Toss until every strand is coated, adding a little extra brine or water if the sauce seems too thick. The consistency should be lush and enough to cling to the noodles without clumping.
- Finish and serve.
Top with the remaining 1/2 cup of kimchi and any optional garnishes you crave. If you’re making this ahead, keep in mind that the sauce will thicken further in the fridge—simply adjust with more brine or water as needed when serving. The noodles are delicious right away, at room temperature, or cold—making them perfect for meal prep or picnics.
What Makes This Noodle Dish Special?
- Minimal ingredients, maximum impact: Just peanut butter and kimchi (plus noodles and water) create deep complexity; you don’t need soy sauce, sesame oil, or exotic pantry items.
- Customizable heat and tang: Adjust the ratio of kimchi brine to water to control the spiciness and acidity.
- An easy weeknight winner: One pot, one bowl, one blender—cleanup’s a breeze.
- Perfect hot or cold: Serve straight from the bowl or enjoy leftovers chilled; both are equally delicious.
Step-by-Step Guide: Detailed Instructions
- Cook Noodles
- Fill a large saucepan with water and bring to a boil. Season it generously with salt.
- Add 1/2 pound noodles and cook until tender but still pleasantly chewy. This usually takes 8–10 minutes for spaghetti; adjust if using another noodle type.
- As soon as the noodles reach an al dente texture, drain and immediately rinse under cold water. Toss gently to cool all strands. Shake the colander to remove water; this step ensures you’ll have slippery, separated noodles perfect for tossing.
- Prepare the Sauce
- In a food processor or blender, combine 1/3 cup unsweetened peanut butter with 1/2 cup chopped kimchi (reserve brine and remaining kimchi for later).
- Pulse until mostly smooth, occasionally scraping the sides down.
- Start by adding 3 tablespoons of liquid—ideally half kimchi brine and half water for balanced heat and tang. Blend to create a creamy, pourable sauce. Taste. Adjust salt or liquid as needed (add more water or brine for a thinner sauce).
- Combine and Adjust Texture
- Transfer the sauce to a large heatproof bowl.
- Add the cooled noodles. Toss thoroughly until each strand glistens with sauce. If it feels gloopy, thin out with more liquid a tablespoon at a time.
- Garnish and Serve
- Pile the remaining 1/2 cup kimchi on top. Finish with fresh toppings like cucumber, scallion, cilantro, or toasted peanuts. Enjoy immediately or let rest at room temperature up to 2 hours; these noodles also taste amazing cold. Store leftovers in the fridge, remembering to thin the sauce before eating if it’s become thick.
Tips, Tricks, and Ingredient Substitutions
- No peanut butter? Try almond or cashew butter for a different nutty note; just avoid sweetened versions.
- Allergy-friendly? Sunflower seed butter can stand in for peanut butter to make this nut-free.
- Different kimchi? Napa cabbage kimchi yields the best results for this dish, but radish or cucumber kimchi also work well.
- No food processor? Chop the kimchi as finely as possible and mix by hand; the sauce will still taste great, with a chunkier texture.
- Make it a meal: Add shredded rotisserie chicken, tofu cubes, or a handful of blanched greens to the noodles before tossing with sauce for added protein and heft.
Table: Sauce Customization Tips for the Perfect Bowl
| Sauce Component | Effect | Tip |
|---|---|---|
| More Kimchi Brine | Increases spicy, sour notes | Boost for a tangier finish |
| More Water | Mellows overall flavor | Use when sauce tastes too intense |
| Chunky vs. Creamy Peanut Butter | Changes texture | Choose creamy for silky smooth, or chunky for added crunch |
| Extra Kimchi | More crunch and fermentation complexity | Pile on as a topping for bonus flavor and texture |
| Thick vs. Thin Sauce | Affects how well it coats noodles | Thin with water/brine as needed just before tossing noodles |
Noodle Choices: What to Use (And What to Avoid)
- Spaghetti or Linguine: Reliable pantry staples, chew in every bite, and carry bold sauce well.
- Asian wheat noodles: Such as udon or ramen noodles; provide a springy bite and authentic character.
- Soba: Their nutty buckwheat flavor complements this sauce beautifully.
- Avoid: Rice noodles or glass noodles, which lack the structure to hold onto the rich peanut-kimchi sauce.
Meal Prep & Serving Suggestions
- Toss noodles and sauce together just before serving to keep flavors punchy.
- Great make-ahead: store undressed noodles and sauce separately up to a day in advance and combine when ready to eat.
- This dish holds well at room temperature for 1–2 hours, making it a picnic and potluck favorite. Refrigerated, it keeps for 2 days, though you may need to thin the sauce on day 2.
- Leftovers are delicious cold or gently refreshed with a splash of water or kimchi brine.

Frequently Asked Questions (FAQs)

A: Store leftovers in an airtight container in the fridge. Thin the sauce with a splash of water or brine before serving, as it thickens when chilled. Enjoy within two days.
Q: Can I prep the sauce ahead of time?
A: Absolutely. The sauce keeps in the fridge for up to 3 days. Stir before using and thin with water or brine as needed.
Q: Which brands of kimchi and peanut butter should I use?
A: Any good-quality, unsweetened peanut butter works. For store-bought kimchi, look for brands with clean labels that taste bright, spicy, and crunchy—avoid overly fishy or soft styles for the best fresh flavor.
