What you will need
This recipe uses 6 simple ingredients that you can find at any grocery store:
- 400 g fresh jjajangmyeon noodles or udon
- 250 g pork belly cut into 1cm cubes
- 5 tbsp chunjang fermented black bean paste
- 2 medium zucchini diced into 1cm cubes
- 1 large white onion diced
- 2 tbsp potato starch or cornstarch
Step by step instructions
Step 1: Fry the Black Bean Paste
Heat 3 tablespoons of neutral oil in a wok or large pot over medium heat. Add the chunjang black bean paste and fry it in the oil, stirring constantly for 3 minutes until it becomes fragrant and slightly less bitter. Remove and set aside. This step significantly improves the flavor of the paste.
Step 2: Cook the Pork and Vegetables
Increase heat to high. Stir-fry the pork belly cubes until lightly browned, about 4 minutes. Add diced onion and zucchini and cook for 3 more minutes until the vegetables soften slightly but retain some texture. Season lightly with salt.
Step 3: Make the Sauce
Return the fried black bean paste to the wok and stir to coat the pork and vegetables. Add 400ml of water and bring to a boil. Mix potato starch with 3 tablespoons of cold water and drizzle in while stirring to thicken the sauce to a glossy gravy consistency. Simmer for 5 minutes.
Step 4: Cook Noodles and Serve
Cook fresh noodles in boiling unsalted water for 2 to 3 minutes until tender. Drain well and divide between bowls. Ladle the black bean sauce generously over the noodles. Serve with sliced raw cucumber and yellow pickled daikon radish on the side. Mix vigorously before eating.
Easy substitutions
Missing an ingredient? Here are some swaps that work perfectly:
- chunjang fermented black bean paste → Chinese dried black bean paste tian mian jiang for a sweeter and slightly different but compatible flavor
- pork belly → diced chicken thighs or firm tofu for a lighter version that still works beautifully with the sauce
Common mistakes to avoid
Watch out for these pitfalls that can affect your results:
- Skipping the step of frying the chunjang paste in oil which leaves a raw bitter metallic taste in the final sauce
- Not thickening the sauce enough with starch which produces a watery result instead of the characteristic glossy coating sauce
