Prep
Prepare ingredients
Chop kimchi into bite-sized pieces if not already chopped. Thinly slice pork belly or press and cube tofu. Slice onion, mushrooms, zucchini (if using), and separate scallion whites from greens; slice both.
Measure out kimchi juice from the kimchi jar; reserve 1 cup. Gather stocks and seasonings so they are ready.
Build the Soup
Sear protein
Heat 1 tablespoon oil in a large pot over medium-high heat. Add the thinly sliced pork belly in a single layer; cook, stirring occasionally, until the edges begin to brown and some fat renders, about 4–5 minutes. If using tofu, gently brown cubes on all sides for 3–4 minutes, then remove and set aside.
Deglaze & add liquids
Pour in kimchi juice, dashi stock, water, and optional additional stock. Scrape the bottom of the pot to lift browned bits. Bring the mixture to a gentle boil over medium-high heat.
Season & simmer
Stir in soy sauce, fish sauce, sugar, kosher salt, and black pepper. Reduce heat to medium-low and simmer uncovered for 15–20 minutes so the flavors meld and kimchi softens further. Taste and adjust salt or chili: add up to 1 tablespoon more gochugaru or 1 teaspoon more fish sauce if desired for extra heat/umami.
Finish with protein & tofu
If you browned pork earlier, ensure it is cooked through in the simmering broth (pork slices will be tender after 5–7 minutes simmer). If using tofu, gently fold the reserved browned tofu cubes into the simmering soup for the last 3–4 minutes to heat through without breaking.
Serve & Garnish
Ladle the soup into bowls, making sure to include kimchi, pork or tofu, mushrooms, and broth. Sprinkle sliced scallion greens on top, drizzle with 1/2 teaspoon sesame oil per bowl, and finish with a pinch of toasted sesame seeds and an optional dusting of gochugaru for extra color and heat.
Serve hot with steamed rice and banchan (side dishes) if desired. Leftovers keep well refrigerated for up to 3 days; reheat gently and add a splash of water or stock if the soup concentrates.
