Spicy Fermented Korean Kimchi (Printable)

Fermented napa cabbage seasoned with spicy chili paste creates this tangy Korean staple packed with probiotics and bold umami flavor.

# What You Need:

→ Produce

01 - 1 large napa cabbage, approximately 2.5 lbs, cut lengthwise into quarters then chopped into 2-inch pieces
02 - 1 medium daikon radish, approximately 7 oz, julienned
03 - 4 scallions, sliced
04 - 1 medium carrot, julienned (optional)

→ Salt & Water

05 - ⅓ cup coarse sea salt
06 - 6 cups cold water

→ Spice Paste

07 - 6 cloves garlic, minced
08 - 1 thumb-sized piece fresh ginger, peeled and minced
09 - 1 small onion, roughly chopped
10 - 3 tablespoons fish sauce or soy sauce for vegan preparation
11 - 1 tablespoon sugar
12 - 3 to 5 tablespoons Korean red chili flakes (gochugaru), adjusted to taste preference
13 - 2 tablespoons rice flour
14 - ⅔ cup water

# How-To:

01 - Cut the napa cabbage lengthwise into quarters, then chop into 2-inch pieces.
02 - Dissolve sea salt in 6 cups cold water in a large non-reactive bowl. Add cabbage pieces, tossing to coat evenly. Place a plate and weight on top to keep submerged. Let sit for 2 hours, tossing every 30 minutes.
03 - Rinse the salted cabbage thoroughly under cold water 2 to 3 times to remove excess salt. Drain well and set aside.
04 - Whisk rice flour with ⅔ cup water in a small saucepan over medium heat, stirring constantly until thickened, approximately 1 to 2 minutes. Transfer to a bowl and let cool completely.
05 - In a blender, combine cooled rice paste, minced garlic, minced ginger, chopped onion, fish sauce or soy sauce, and sugar. Blend until smooth and uniform. Transfer to a bowl and stir in gochugaru to reach desired spice intensity.
06 - In a large bowl, combine drained cabbage, julienned daikon radish, carrot if using, and sliced scallions. Add spice paste and, wearing kitchen gloves, massage thoroughly to coat all vegetables evenly with the seasoning mixture.
07 - Pack the kimchi tightly into clean glass jars or a fermentation crock, pressing down firmly to eliminate air pockets. Leave at least 1 inch headspace at the top to allow for gas expansion during fermentation.
08 - Seal the jars and leave at room temperature out of direct sunlight for 1 to 2 days, burping the jars daily to release accumulated gas.
09 - Taste after 48 hours. Once the kimchi reaches desired sourness and tangy flavor, transfer to refrigerator storage. Kimchi will continue to ferment slowly and develop deeper, more complex flavors over several weeks.

# Expert Advice:

01 -
  • You'll actually taste kimchi come alive as it ferments, way more complex than anything store-bought could offer.
  • Once you master this, you'll stop buying expensive jars and become the person everyone asks for kimchi.
  • The whole process feels like kitchen magic—watching plain cabbage transform into something that makes everything taste better.
02 -
  • If your kimchi tastes too salty after rinsing, you skipped one of those rinses or didn't rinse thoroughly enough—don't skip the rinsing step no matter how eager you are.
  • The smell during fermentation will be intense and funky; this is completely normal and means the bacteria are doing exactly what they should, so trust the process.
  • Room temperature matters—fermentation happens fastest between 65–70°F, and will be slower in a cold kitchen, so adjust your timeline expectations based on your environment.
03 -
  • Use a clean glass jar that's never held anything strongly scented; any lingering odor will interfere with the fermentation and your flavor.
  • If white fuzz appears on the surface, that's harmless mold and you just skim it off, but if you see pink or orange discoloration, discard the batch—that means bad bacteria won.
  • Keep extra jars going on a rotation; once you finish one, immediately pack another so you always have kimchi aging to the perfect level.
