Add the Tofu

Carefully add the soft silken tofu to the pot. Use a spoon to gently break it into large chunks. This is where the soup starts to get its signature texture.

Season the Soup

Stir in a bit of sesame oil for that nutty background note. Then, taste your soup and adjust the seasoning with salt, pepper, and a pinch of sugar if needed. It’s all about creating a balanced flavor profile.

Final Touches

Bring the soup to a rolling boil before adding the sliced shiitake mushrooms. Let them cook until soft, then carefully crack an egg into the pot right before you’re ready to serve. The egg adds a rich, creamy texture to the soup.

Garnish and Serve

Sprinkle red pepper flakes and green onions on top for a pop of color and flavor. Serve your Korean Tofu Soup hot, and get ready to enjoy a bowl of comfort.

Recipe Notes and Expert Tips

Here are some insider tips to make your Korean Soft Tofu Soup even better:

  • Keep it fresh: Use fresh, high-quality ingredients for the best flavor, especially when it comes to the tofu and kimchi.
  • Spiciness: Adjust the spiciness to your liking. Add more or less red pepper flakes based on your preference for heat, or add powdered Korean red pepper flakes (gochugaru) to dial up the heat to your liking.
  • Runny egg tips: Don’t boil the soup after adding the egg if you want it to remain slightly runny and enrich the broth.
  • More veggies: Add extra vegetables! It’s a great way to use up what’s in your fridge.
  • Seasoning: Taste as you go and remember that the saltiness of kimchi can vary, so adjust your seasoning accordingly. If you need a little more saltiness, a splash of soy sauce is ideal.
  • Kimchi: To keep this recipe vegetarian, double-check the ingredients in your kimchi. Some kimchi brands include seafood or fish sauce.
  • Make it vegan: This particular recipe is vegetarian, but you can easily make it vegan by making sure you use vegan kimchi (some brands include fish sauce) and skipping the egg. Adding seaweed or dried kelp can mimic the umami flavors while keeping it plant-based.
  • Can I make Korean Tofu Soup without kimchi? Yes, you can! While kimchi adds a distinctive flavor, you can substitute it with a dash of vinegar and a pinch of chili flakes for a similar tang and heat.

How to Store Leftover Korean Tofu Soup

Storing your leftover Korean Soft Tofu Stew is easy, and it tastes just as good the next day. Here’s how to keep it fresh:

  • Cool & Airtight: Let it cool before storing, and then use an airtight container to store the soup in the refrigerator. 
  • Shelf life: Consume within 3-4 days for the best taste and quality. The flavors will continue to meld and develop over time.
  • Reheating: Reheat gently over medium heat until it’s warm throughout. Be careful not to bring it to a boil, especially if there’s an egg in the soup, to maintain the texture.
  • Can I freeze Korean Tofu Soup? Freezing is possible, but the texture of the tofu may change, becoming spongier. It’s best enjoyed fresh or stored in the refrigerator if you plan to eat it within a few days.

What to Serve with Korean Tofu Soup

Pairing your Korean Tofu Soup with the right sides can turn it into a feast. Here are some great ideas that complement the flavors of the soup:

Steamed Rice

A bowl of fluffy, steamed rice is a must-have with Korean Tofu Soup. It balances the soup’s spiciness and makes the meal more satisfying. Plus, it’s great for soaking up the delicious broth.

Banchan (Korean Side Dishes)

Korean meals often come with an assortment of side dishes known as Banchan. Think of small plates like seasoned vegetables, kimchi, or pan-fried tofu. These sides add a delicious variety of flavors and textures to your meal. Our Korean Cucumber Salad is ideal!

Grilled or Roasted Vegetables

For a healthier option, serve your soup with roasted or grilled vegetables. Zucchini, bell peppers, and mushrooms make excellent choices. Grilling them adds a smoky flavor that pairs wonderfully with the soup’s depth.
