Ingredients
- 1 tablespoon olive oil
- 1 medium yellow onion, diced
- 2 medium carrots, peeled and diced
- 2 celery stalks, diced
- 3 garlic cloves, minced
- 1-inch piece fresh ginger, peeled and minced
- 1 cup dried brown or green lentils, rinsed
- 1 cup napa cabbage kimchi, chopped (plus more for garnish)
- 4 cups low-sodium vegetable broth
- 2 cups water
- 2 tablespoons gochujang (Korean chili paste) or 1 tablespoon sriracha
- 1 tablespoon soy sauce or tamari
- 1 teaspoon toasted sesame oil
- 1 teaspoon ground cumin
- 1 teaspoon smoked paprika
- 1/2 teaspoon ground black pepper
- 1 cup baby spinach (optional)
- 2 scallions, thinly sliced (for garnish)
- 1 tablespoon toasted sesame seeds (for garnish)
- Salt, to taste
Instructions
- Heat the olive oil in a large soup pot or Dutch oven over medium heat. Add the diced onion, carrots, and celery. Sauté for 5-7 minutes, stirring occasionally, until the vegetables are softened and onions are translucent.
- Add the minced garlic and ginger. Cook for 1-2 minutes, stirring frequently, until fragrant.
- Stir in the rinsed lentils, chopped kimchi, gochujang (or sriracha), soy sauce, sesame oil, cumin, smoked paprika, and black pepper. Cook for 1-2 minutes to let the flavors combine.
- Pour in the vegetable broth and water. Stir well and bring the mixture to a boil over high heat.
- Once boiling, reduce the heat to low and cover. Simmer for 25-30 minutes, or until the lentils are tender and the soup has thickened. Stir occasionally and add more water if you prefer a thinner consistency.
- Taste and adjust the seasoning with salt, more soy sauce, or a splash of kimchi juice for extra tang.
- If using baby spinach, stir it in during the last 2-3 minutes of cooking until wilted.
- Ladle the soup into bowls. Garnish with extra kimchi, scallions, and toasted sesame seeds. Serve hot.
Tips
- Lentil types: Brown or green lentils hold their shape best, but you can use red lentils for a softer, creamier texture. Adjust cooking time if using red lentils (15-20 minutes).
- Kimchi heat: Choose mild or spicy kimchi based on your preference. If your kimchi is very spicy, reduce the gochujang or sriracha as needed.
- Make it gluten-free: Use tamari instead of soy sauce and double-check that your gochujang is gluten-free.
- Common mistake: Avoid adding kimchi too early or cooking it for too long, as prolonged boiling can diminish its probiotic benefits and flavor. Add half the kimchi at the start for flavor, and stir in extra at the end for crunch and live cultures.
Serving Suggestions
- Serve the soup with a side of steamed jasmine or brown rice for a more filling meal.
- Top each bowl with a soft-boiled or poached egg for extra protein (omit for vegan).
- Add a drizzle of chili oil or a dash of rice vinegar for extra flavor depth.
- Pair with a crisp green salad or pickled vegetables to balance the warm, spicy flavors.
Variations
- Protein boost: Add cubed firm tofu in the last 10 minutes of simmering for a heartier, plant-based soup.
- More veggies: Stir in sliced mushrooms, zucchini, or bell pepper along with the carrots and celery for extra texture and nutrition.
- Grain swap: Replace lentils with cooked quinoa or farro for a different texture and nutritional profile; reduce simmering time accordingly.
- Meaty version: Add shredded rotisserie chicken or cooked ground turkey during the last few minutes for a non-vegan option.
Storage and Reheating
Kimchi lentil soup stores well and often tastes even better the next day as the flavors meld. Allow the soup to cool completely before transferring to airtight containers. Store in the refrigerator for up to 4 days. For longer storage, freeze individual portions for up to 3 months. To reheat, warm gently on the stovetop over medium heat, stirring occasionally until hot. If reheating from frozen, thaw overnight in the refrigerator or defrost in the microwave before reheating. Add a splash of water or broth if the soup has thickened too much during storage.
Frequently Asked Questions
- Can I use canned lentils instead of dried?
Canned lentils can work in a pinch; simply drain and rinse them, and reduce the simmering time to 10-15 minutes since canned lentils are already cooked. Add them after the vegetables have softened and simmer just long enough to blend the flavors. The texture will be softer, but the soup will still be tasty. - Is this soup vegan and gluten-free?
The base recipe is vegan as long as you use vegetable broth and omit any egg garnish. For gluten-free, be sure to use tamari instead of soy sauce and confirm that your gochujang or chili paste is certified gluten-free, as some brands contain wheat. - How spicy is kimchi lentil soup?
The heat level depends on your kimchi and the amount of gochujang or chili paste you use. For a milder soup, use mild kimchi and reduce the chili paste. For more heat, add extra sriracha or a pinch of red pepper flakes at the end. - Can I make this in an Instant Pot or slow cooker?
Yes! For the Instant Pot, use the sauté function for steps 1-3, then add all ingredients except spinach and garnishes. Cook on high pressure for 10 minutes, natural release for 10 minutes, then quick release and stir in spinach. For a slow cooker, sauté the aromatics first, then add all ingredients and cook on low for 6-7 hours or high for 3-4 hours. Add spinach near the end. - What if I don’t have gochujang?
If you don’t have gochujang, substitute with sriracha, sambal oelek, or another favorite chili paste. Each has a slightly different flavor profile, so start with less and adjust to taste. You can also add a small spoonful of miso paste for extra umami if desired. - Can I freeze kimchi lentil soup?
Yes, this soup freezes very well. Let it cool completely, then portion into freezer-safe containers. Freeze for up to 3 months. When ready to eat, thaw overnight in the fridge or use the defrost setting on your microwave. Reheat gently and add a splash of water or broth if needed to loosen the soup.
