Jajangmyeon (Korean Black Bean Noodles)

Why You’ll Love This Recipe

I love how flavorful and filling this dish is while still being surprisingly simple to prepare. The black bean sauce becomes thick, savory, slightly sweet, and deeply rich after simmering with pork, garlic, ginger, and vegetables.

Another reason I enjoy making jajangmyeon is how customizable it can be. I can swap the pork for chicken or seafood, adjust the sauce consistency, or add extra vegetables depending on what I have available.

I also appreciate how quickly it comes together, making it perfect for weeknight dinners when I want something warm and comforting.

Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

• ⅔ cup Korean black bean paste (chunjang)
• ¼ cup neutral oil
• 1 pound boneless pork shoulder, diced
• 3 tablespoons garlic, minced
• 1 tablespoon ginger, minced
• 1 medium yellow onion, diced
• 10 ounces green cabbage, chopped
• 1 Korean zucchini, diced
• 2 cups water
• 3 tablespoons oyster sauce
• 2 tablespoons granulated sugar
• 3 tablespoons cornstarch
• 3 tablespoons water, for slurry
• 4 bundles Korean fresh noodles
• English cucumber, julienned
• Kimchi, optional
• Danmuji (pickled yellow radish), optional

Directions

1. I begin by heating oil in a small saucepan over medium heat and stir-frying the black bean paste for about 2 minutes until fragrant.
2. I remove the black bean paste from the heat and set it aside.
3. In a large pot or saucepan, I lightly coat the bottom with oil and heat it over medium-high heat.
4. I add the diced pork and stir-fry until browned and fully cooked.
5. I reduce the heat slightly and add the minced garlic and ginger, cooking briefly until fragrant.
6. I add the onion, cabbage, and zucchini and cook until the cabbage starts to soften.
7. I stir the fried black bean paste into the vegetables and pork until everything is evenly coated.
8. I pour in the water, oyster sauce, and sugar, then bring the sauce to a boil.
9. I lower the heat and let the sauce simmer for 10 to 15 minutes until rich and flavorful.
10. While the sauce cooks, I boil the noodles according to the package instructions and drain them well.
11. If using fresh Korean noodles, I rinse them briefly with water to remove excess starch before draining again.
12. I divide the noodles into serving bowls.
13. I mix the cornstarch with water to make a slurry, then slowly stir it into the simmering sauce until thickened and glossy.
14. I ladle the hot black bean sauce over the noodles and top with julienned cucumber.
15. I serve the jajangmyeon immediately with kimchi and pickled radish on the side if desired.

Variations

I sometimes replace the pork with chicken, shrimp, or tofu for different variations of the dish. Pork belly also creates an extra rich and flavorful sauce.

For added spice, I like serving the noodles with spicy kimchi or a drizzle of chili oil. I also enjoy adding mushrooms, potatoes, or peas for more texture and flavor.

When I want a seafood-inspired version, I add squid or shrimp while simmering the sauce.

storage/reheating

I store leftover sauce and noodles separately in airtight containers in the refrigerator for up to 3 days. Keeping them separate helps the noodles stay chewy instead of becoming overly soft.

For reheating, I warm the sauce gently in a saucepan over medium heat and add a splash of water if it becomes too thick. I quickly reheat the noodles in hot water or the microwave before serving.

I do not usually freeze the noodles, but the sauce freezes well for up to 2 months.
