Step‑by‑Step Instructions for 15-Minute Kimchi Udon Stir Fry
Step 1: Prep Noodles
Begin by soaking the frozen udon noodles in hot water for about 1 minute. Using chopsticks, gently loosen the noodles, ensuring they separate well. Once loosened, drain them, rinse briefly under cold water, and set aside to stop the cooking process. This prepped base will hold up beautifully in your flavorful kimchi udon stir fry.
Step 2: Cook Protein
In a large skillet or wok, heat 1 tablespoon of vegetable oil over medium heat. Once hot, add the sliced pork belly, spreading it evenly in the pan. Fry the pork for about 4-5 minutes, or until it turns golden brown and crispy. Stir occasionally for even cooking. The sizzling of pork belly adds an irresistible aroma to your 15-minute kimchi udon stir fry.
Step 3: Saute Aromatics
Next, add the sliced onion and green onion to the pan with the pork. Stir-fry for about 2-3 minutes, allowing the onions to soften and become fragrant. You want the onions to become translucent and slightly caramelized, enhancing the overall flavor of your stir fry. This step sets a tasty foundation for the kimchi to shine.
Step 4: Add Kimchi
Stir in the diced aged kimchi along with a sprinkle of sugar. Cook everything together for an additional 2 minutes, allowing the kimchi to soften and release its tangy juices. At this point, the vibrant colors and bold scents will fill your kitchen, elevating your anticipation for the final dish.
Step 5: Build Sauce
Pour in the gochugaru, kimchi juice, oyster sauce, and water into the pan, mixing well to combine. Let the mixture simmer for about 1 minute, allowing the sauce to thicken slightly. As it cooks, the savory and spicy aromas will deepen, showcasing the unique flavors of your kimchi udon stir fry that will coat the noodles beautifully.
Step 6: Combine Noodles
Add the prepped udon noodles to the skillet, tossing them gently to coat in the delicious sauce. Stir everything for about 2 minutes, ensuring the noodles absorb the flavors while warming through. Check the seasoning, adding salt if necessary to enhance the taste of your quick kimchi udon stir fry.
Step 7: Finish with Sesame Oil
Finally, drizzle sesame oil over the stir fry and mix gently to combine. Let it rest for a minute off the heat to allow the flavors to meld together. This finishing touch adds a lovely aroma and depth to your kimchi udon stir fry, making it tempting to dig in right away!

15-Minute Kimchi Udon Stir Fry Recipe FAQs
How do I select the right kimchi for my stir fry?
Absolutely! For the best flavor, always opt for aged kimchi. Aged kimchi has a deeper, more complex taste and packs a punch in your dishes. However, if you’re in a pinch, fresh kimchi can work, but I recommend letting it sit at room temperature overnight for some natural fermentation to add that extra depth.

How should I store leftovers of the kimchi udon stir fry?
Leftovers can be stored in an airtight container in the refrigerator for up to 2 days. Be sure to let it cool completely before sealing to avoid excess moisture. When reheating, I suggest using the stovetop over medium heat, adding a splash of water or broth to bring back its delicious texture.
Can I freeze my kimchi udon stir fry?
Yes, definitely! You can freeze your stir fry (without garnishes) for up to 1 month. To do this, let the stir fry cool completely, then portion it into freezer-safe containers. When you’re ready to eat, simply thaw in the fridge overnight and reheat on the stovetop, adding a bit of water to keep it moist.
What if my udon noodles turn mushy during cooking?
The key to achieving that perfect udon noodle texture is to use frozen noodles. Frozen udon noodles hold their shape better during stir-frying. If you accidentally overcook them, try to pull them out of the hot water sooner next time, keeping them just loose enough to easily separate. Keeping a close eye during the sautéing step will also help maintain their chewiness.
Are there any dietary concerns I should keep in mind?
Very! This dish contains pork belly, which may not be suitable for everyone. If anyone in your family has dietary restrictions or avoids certain foods, feel free to substitute with chicken, tofu, or additional vegetables. Always check your kimchi for allergens, as some brands may contain seafood or other ingredients to be mindful of.
How can I adjust the spice level in my kimchi udon stir fry?
The more the merrier when it comes to flavors! Start with a small amount of gochugaru and taste as you go. If you find it too spicy, you can add more sugar or even a little soy sauce to balance it out. Alternatively, swap out gochugaru for a milder chili powder if you’re cooking for people who prefer gentle heat. This customization will help everyone enjoy the 15-Minute Kimchi Udon Stir Fry!
