Korean Soup Austin: Spicy Kimchi Jjigae for Dinner

Korean kimchi jjigae is a bubbling, savory soup-stew made with kimchi, broth, tofu, and often pork; it is served hot with rice. Versions vary by household and region, and this practical Austin-friendly recipe uses ingredients that are easy to find in many U.S. grocery stores, with swaps for specialty Korean ingredients.

Ingredients

8 ounces (225 g) ground pork
1 tablespoon (15 ml) neutral cooking oil, such as canola
1 medium yellow onion, about 1 cup sliced (150 g)
2 cups (300 g) well-fermented napa cabbage kimchi, roughly chopped
1/4 cup (60 ml) kimchi brine, taken from the jar
4 garlic cloves, finely chopped (about 12 g)
1 tablespoon (6 g) gochugaru, Korean red pepper flakes
1 tablespoon (18 g) gochujang, Korean chili paste
4 cups (950 ml) low-sodium chicken broth or water
1 tablespoon (15 ml) fish sauce
1 teaspoon (4 g) granulated sugar, optional, to balance very sharp kimchi
14 ounces (400 g) medium-firm or firm tofu, drained and cut into 1-inch (2.5 cm) pieces
2 scallions, thinly sliced (about 30 g)
1/4 teaspoon (0.5 g) black pepper
Cooked rice, for serving, optional

Instructions

Prepare the ingredients. Slice the onion, chop the kimchi into bite-size pieces, mince the garlic, and cut the tofu. Keep the kimchi brine; it brings concentrated seasoning and acidity to the pot. Set out the broth, fish sauce, gochugaru, and gochujang so they can be added without interrupting the cooking.
Brown the pork. Heat the oil in a medium heavy pot over medium-high heat. Add the ground pork and break it into small crumbles with a wooden spoon. Cook for about 6 to 8 minutes, stirring regularly, until no pink remains. Check the thickest crumbles with a food thermometer: USDA FSIS lists 160°F (71°C) as the safe minimum internal temperature for ground meat. If the pork releases a lot of fat, spoon off some, leaving about a tablespoon in the pot for flavor.
Soften the onion. Add the sliced onion and cook for 3 minutes, stirring, until it begins to turn translucent. Stir in the kimchi, garlic, and gochugaru. Cook for 3 minutes, letting the kimchi heat through and the garlic smell fragrant. Avoid letting the garlic or pepper flakes scorch; lower the heat if the bottom of the pot begins to darken quickly.
Season and add broth. Stir in the gochujang until it coats the pork and kimchi. Pour in the broth and kimchi brine, then add the fish sauce and black pepper. Add the optional sugar only if your kimchi is particularly sour. Scrape the bottom of the pot to loosen browned bits, then bring the liquid to a gentle boil, about 3 minutes.
Simmer the soup. Lower the heat so the soup bubbles steadily but does not boil hard. Partially cover the pot and simmer for 15 minutes, stirring once or twice. This gives the pork and kimchi time to share their flavor with the broth. Taste near the end: if it needs more salt, add fish sauce a teaspoon at a time; if it is too intense, add a splash of water or broth.
Add tofu and finish. Nestle the tofu pieces into the soup and simmer gently for 3 minutes, just until warmed through. Stir carefully so the tofu stays in pieces. Taste once more, then scatter the sliced scallions over the top. Serve right away while the broth is hot.

Tips

Choose ripe kimchi. Well-fermented kimchi gives jjigae its characteristic tang and depth. Fresh, mild kimchi can still work, but the soup may taste less complex; add a teaspoon of rice vinegar near the end if you want more brightness, then taste before adding more.
Adjust the heat in small steps. Gochugaru provides warmth and color, while gochujang adds chili flavor, sweetness, and body. If you are sensitive to spice, start with half the gochugaru and use mild kimchi. You can add more flakes at the simmer stage, but it is harder to correct a pot that is already too hot.
Keep the broth balanced. Kimchi, its brine, and fish sauce can all be salty. Use low-sodium broth or water, then season at the end. A little sugar can round out sharp acidity, but it should not make the broth taste sweet.
Handle tofu gently. Medium-firm tofu holds its shape while absorbing broth; firm tofu is easier to portion. Silken tofu is a possible substitute, but it will break apart more readily and make the soup softer and cloudier.

Serving Suggestions

Serve kimchi jjigae in individual bowls with steamed short-grain rice, which makes the spicy, salty broth easier to enjoy and turns the soup into a filling meal. For a simple rice preparation, rinse 1 cup (185 g) of short-grain rice until the water is less cloudy, then cook it according to the package directions while the soup simmers. Spoon the soup beside or over the rice, depending on how you like to eat it.

Small Korean-style side dishes make a good contrast, especially crisp cucumber, seasoned bean sprouts, or a mild vegetable banchan. If you do not have those on hand, serve sliced cucumber or a lightly dressed green salad. Put extra scallions on the table for anyone who wants a fresher onion note. Because the stew is already boldly seasoned, keep sides fairly simple rather than adding several salty or spicy dishes.

For a casual meal, bring the pot to the table on a heat-safe trivet and ladle portions into bowls. Make sure each serving gets some pork, kimchi, and tofu. Offer water and rice alongside; the broth can be quite spicy, particularly if the kimchi and pepper flakes are both hot.

Variations

Use a traditional anchovy-kelp broth. Replace the chicken broth with 4 cups (950 ml) of anchovy-kelp stock for a more distinctly Korean savory base. Dried anchovies and dried kelp, also called dashima, may be less familiar in an Austin pantry. If you cannot find them, water or low-sodium chicken broth is a dependable substitute; the flavor will be less ocean-savory, but the kimchi still gives the soup plenty of character. Avoid simmering kelp for a long time, since it can make stock bitter.

Make it vegetarian. Leave out the pork and fish sauce, and use vegetable broth or water. For extra substance, add 6 ounces (170 g) of sliced mushrooms with the onion and season with 1 tablespoon (15 ml) soy sauce instead of fish sauce. Check that the kimchi itself contains no fish sauce or salted seafood if you need the whole pot to be vegetarian; recipes and brands differ.

Change the protein or vegetables. Thinly sliced pork belly is a common alternative to ground pork; cook it until browned before adding the onion. For a seafood version, add peeled shrimp near the end and cook until opaque and firm. Add greens such as napa cabbage or spinach during the last few minutes, or add sliced mushrooms with the kimchi. These changes affect texture and saltiness, so taste the broth before serving. If using shrimp, check that it reaches 145°F (63°C), the USDA FSIS safe minimum temperature for fish and seafood.

Make a milder pot. Reduce the gochugaru to 1 teaspoon (2 g), omit the gochujang, and choose mild kimchi. The result will be less red and less spicy, but still savory and tangy. Keep extra gochugaru on the table so each diner can adjust an individual bowl.

Storage and Reheating

Refrigerate leftovers within 2 hours of cooking. Transfer the soup to shallow, covered containers so it cools promptly, and keep it refrigerated for 3 to 4 days. The broth will continue to take on kimchi flavor as it sits, while tofu may become softer. If you expect leftovers, you can store some tofu separately and add it when reheating, though it is also fine to store everything together.

For longer storage, freeze the cooled soup in airtight freezer-safe containers for up to 2 to 3 months for best quality. Leave a little space at the top because liquid expands as it freezes. Thaw overnight in the refrigerator for the most even reheating. The tofu may turn slightly more porous or chewy after freezing, a texture change rather than a sign that it has spoiled.

Reheat only the portion you plan to eat in a saucepan over medium heat, stirring occasionally, until steaming throughout and at least 165°F (74°C). Add a splash of water or broth if the soup has thickened. You can also microwave a portion in a covered, microwave-safe bowl, stirring halfway through and checking that the center reaches 165°F (74°C). Avoid repeatedly cooling and reheating the whole pot.

Frequently Asked Questions

What is Korean kimchi jjigae?
Kimchi jjigae is a Korean stew-like soup built around kimchi and its brine. Pork and tofu are common additions, though ingredients differ across home and regional versions. It is generally served hot with rice, and its taste can range from gently tangy to quite spicy depending on the kimchi and seasonings.

Can I make this without gochujang?
Yes. Leave it out and add a little extra gochugaru if you want more heat. Gochujang contributes sweetness and a thicker, rounded chili flavor, so the broth will taste cleaner and less full-bodied without it. Do not replace it with a large amount of hot sauce, which can add vinegar and salt in proportions that throw off the soup.

How do I make the soup less sour?
Use less kimchi brine, choose a less fermented kimchi, or stir in the optional teaspoon of sugar. A small amount of broth or water can also soften the overall intensity. Adjust one thing at a time and taste after each addition so the soup does not become bland or unexpectedly sweet.

Can I prepare kimchi jjigae ahead?
Yes. You can chop the vegetables and tofu and measure the seasonings a day ahead, keeping them covered in the refrigerator. The soup itself can also be cooked ahead and refrigerated for 3 to 4 days. Reheat it to 165°F (74°C) and expect the kimchi flavor to deepen slightly as it rests.

Is kimchi jjigae gluten-free?
It can be, but check the labels on gochujang, fish sauce, broth, and kimchi because ingredients vary. Some chili pastes and prepared broths contain wheat or other additives. Choose products labeled gluten-free when needed, or omit the gochujang and use a suitable broth; the soup will have a different but still enjoyable flavor.
