Why You’ll Love this Authentic Korean Kimchi

If you’ve never made kimchi at home before, you’re probably thinking it’s one of those intimidating fermented foods that requires a PhD in microbiology or at least a Korean grandmother on speed dial.

But here’s the thing: this recipe proves otherwise. I love that it’s fundamentally just cabbage, salt, and time doing their magic together.

The process is forgiving, the ingredients are straightforward, and the payoff is incredible. You get tangy, spicy, crunchy perfection that transforms everything from rice bowls to burgers.

Plus, making your own means controlling the heat level and customizing flavors exactly how you want them.

What Ingredients are in Authentic Korean Kimchi?

The beauty of this kimchi recipe is that it doesn’t require a massive shopping list or weird ingredients you’ll never use again. Well, except maybe the kimchi sauce, which comes in a bottle that could last you until the next ice age.

But honestly, most of what you need is probably already hanging out in your kitchen or easily found at your regular grocery store. The star of the show is Chinese cabbage (which, yes, has a confusing name for a Korean recipe, but let’s not overthink it), and from there it’s mostly about building layers of flavor with aromatics, heat, and a good amount of salt to get the fermentation party started.

For the kimchi base:

  • 2 Chinese cabbages
  • 100 g sea salt or other non-iodized salt (at least 100 g)
  • 5-10 spring onions

For the flavor paste:

  • 4 tablespoons Korean chili powder (about 20 g)
  • 2-3 garlic cloves, crushed
  • 5 g fresh ginger, crushed, or 1 teaspoon powdered ginger
  • 2 tablespoons sugar (any kind works)
  • 1/2 onion
  • 1 tablespoon kimchi sauce (optional but recommended)

Now, about that salt situation. You absolutely need non-iodized salt here, whether that’s sea salt or plain table salt without the iodine. The iodine messes with fermentation, and nobody wants sad, funky-in-the-wrong-way kimchi.

The Korean chili powder is another ingredient worth seeking out at an Asian market because it has that distinctive bright red color and the right level of heat, but if you can’t find it, you can substitute with other chili powders or even fresh peppers. Just adjust the amount if you’re using something spicier.

And that kimchi sauce, the one that comes in the intimidatingly large bottle? You mightn’t want to know what’s in it (hint: probably fish or oysters), but it does add depth to the flavor. That said, you can skip it if you’re vegetarian or just can’t track it down. The kimchi will still work, it just might take a bit longer to develop that complex fermented taste.

How to Make this Authentic Korean Kimchi

ferment cabbage with salt

The first step is all about getting those 2 Chinese cabbages prepped and properly salted, which is honestly where the magic starts to happen. Rinse them off, quarter them lengthwise, toss out the stems (they’re not doing anyone any favors), and then chop the quarters laterally so you end up with pieces that are about 5 cm on a side. Don’t go all perfectionist chef with your knife skills here, we’re making fermented vegetables, not competing on a cooking show.

Once you’ve got your cabbage pile, grab a clean plastic bag without holes (important detail, trust me) and start layering the cabbage with that 100 g of sea salt or non-iodized salt. Here’s where it gets a little hands-on, and I mean that literally. Sprinkle salt on your wet hands and really work it into the cabbage pieces, squeezing out as much water as you can. This creates a brine with the cabbage juice, which is exactly what we’re going for. Tie up that bag and let it sit for 5-6 hours, checking around the three-hour mark to give it a stir if things look uneven.

After your cabbage has done its salty time, rinse it off if it tastes too salty and squeeze out the extra water. It should feel way softer now, almost wilted. Toss it into a sealable plastic container and add your 5-10 spring onions, chopped into small pieces.

Then comes the flavor bomb: crush those 2-3 garlic cloves and 5 g of fresh ginger (or 1 teaspoon powdered if that’s what you’ve got) using a press, and mix them in. You can also dice up that 1/2 onion and add it if you want, or skip any of these if you’ve got allergies or strong feelings about certain aromatics. Add the 1 tablespoon of kimchi sauce if you managed to find it, though the kimchi will still work without it.

Now dump in those 4 tablespoons of Korean chili powder and 2 tablespoons of sugar, and get ready for another workout. You’ll want to mash and squish that chili powder into the cabbage leaves, kind of like you did with the salt earlier, working it in until everything looks nice and red. Wearing gloves is a smart move here unless you enjoy the sensation of chili powder under your fingernails for the next three days, and hey, if you’ve got a friend around, this is a great time to tag-team the squishing. Your hands will thank you.

Once everything is thoroughly mixed and massaged, seal up your container and stash it in a cool spot, not the fridge yet, for about three or four days. I know it’s tempting to peek and taste, but resist the urge and let the fermentation do its thing.

After those few days are up, move it to the refrigerator where it’ll continue to develop flavor. When it’s finally ready to eat, the kimchi should be soft but still have a little crunch in the bigger pieces, with that perfect balance of salty, spicy, tangy, and just a hint of sweet. You can eat it straight from the container, toss it into a stir fry, or apparently put it on hamburgers if you’re feeling adventurous. If you’re planning to cook with your kimchi in larger batches, a professional casserole baking dish can really elevate dishes like kimchi stew or kimchi fried rice.

Authentic Korean Kimchi Substitutions and Variations

While Sang Mi’s recipe is pretty much perfect as-is, let’s be real, not everyone has access to a Korean grocery store, and sometimes your pantry is just missing that one essential ingredient at the exact moment you’re elbow-deep in cabbage.

No Korean chili powder? Regular chili flakes work, though you’ll lose that signature bright red color.

Can’t find kimchi sauce? Honestly, I’d just skip it rather than substitute something weird.

The garlic and ginger are flexible too—hate one, leave it out.

And here’s a fun twist: swap cabbage for radish cubes to make kakk du gi instead. Same method, different crunch.

What to Serve with Authentic Korean Kimchi

Once you’ve got this tangy, fermented masterpiece ready to go, you’re probably wondering what the heck to actually eat it with—because let me tell you, kimchi isn’t exactly the kind of thing you just fork into your mouth straight from the container.

(Well, I mean, you *can*, but your coworkers might give you some looks.) Koreans traditionally serve it as a banchan, which is just a fancy word for those little side dishes that come with literally every Korean meal, sitting there in cute tiny bowls alongside your rice and main dish.

But honestly, kimchi works with almost anything. Toss it into stir-fries, pile it on hamburgers, or mix it with fried rice.

Final Thoughts

Making kimchi at home might seem intimidating at first, what with all the salt-squeezing and cabbage-mashing and waiting around for fermentation to do its thing, but honestly, once you’ve done it a couple times, you’ll wonder why you ever bothered buying those overpriced jars at the grocery store.

The process becomes second nature, and you can tweak the recipe however you want—more garlic, less ginger, whatever suits your taste.

Plus, there’s something satisfying about opening your fridge to see those containers of homemade kimchi waiting for you.

Trust me, your future self will thank you.
