Is kimchi soup the same as kimchi jjigae?
They are close cousins, but not exactly the same thing. Kimchi jjigae is part of the Korean stew category and is often served bubbling hot (frequently in a stone pot). It commonly includes pork or tuna and can be made with anchovy-kelp stock for a deeper, more savory base. This kimchi soup is a lighter, soupier take with a clean, brothy vibe, but it still delivers that classic tangy, spicy kimchi comfort.
How spicy is it?
It depends on your kimchi and your gochujang brand. Start with the amounts listed, then taste the broth before serving. If you want more heat, add a little extra gochujang or a pinch of gochugaru. If you want it milder, start with 1 tablespoon gochujang and add a touch more broth.
What kind of kimchi should I use?
Use well-fermented napa cabbage kimchi (baechu kimchi) for the best flavor. If your kimchi is newer and still mild, let it simmer a few extra minutes. If you still want more tang, you can add 1 to 2 teaspoons rice vinegar as a modern, preference-based boost. (Not traditional, just helpful in a pinch.) If your kimchi is very salty, you may need less soy sauce.
Can I make it vegetarian?
Yes. Use vegetable broth, swap pork for mushrooms, and make sure your kimchi is vegetarian (some contain fish sauce or shrimp).
Why does my soup taste flat?
Usually it needs one of these: more kimchi, a spoon of kimchi juice, a pinch of salt, or a tiny bit of sugar to round out the sour. Taste, adjust, repeat. That is the whole game.
Can I use a more traditional broth?
Absolutely. If you have it, swap the broth for anchovy-kelp stock (dashima and dried anchovy). It adds that deeper, savory Korean soup-shop flavor without extra work.
