Soups & Stews
This Muso Soup recipe delivers the deep, savory richness of traditional Korean pig trotter soup with a modern twist—perfect for those seeking comfort in every spoonful.
The secret lies in slow-simmered broth infused with fermented soybean paste (doenjang) and aromatic mushrooms, creating layers of umami that transform simple ingredients into something extraordinary.
I developed this version after years of refining the balance between tender meat and velvety broth, ensuring every bite delivers that signature Korean depth without compromising on accessibility.
The beauty of this recipe is its versatility—whether you're preparing it for a special occasion or a cozy weeknight dinner, the process is methodical yet forgiving.

For those short on time, a pressure cooker can cut preparation time by half without sacrificing flavor, making it achievable for home cooks of all levels.
What sets this Muso Soup apart is the harmony of textures: silky broth, tender trotters that melt in your mouth, and the subtle crunch of mushrooms that add complexity.

The pig trotters are the heart of this dish—fresh, high-quality trotters from a trusted butcher ensure optimal tenderness. Costco or specialty Asian markets often carry them pre-cleaned, saving significant prep time. If using frozen, thaw overnight in the fridge and parboil for 10 minutes to remove impurities. For the shiitake mushrooms, prioritize fresh over dried—their meaty texture and earthy flavor are irreplaceable. Whole Foods or Trader Joe's typically stock them year-round. The doenjang should be a vibrant, slightly oily paste; Korean grocery stores carry authentic brands like Soy Gochujang or Soy Sauce sections.
No doenjang? Substitute with 1 tbsp miso paste plus 1 tsp gochujang for a similar depth, though the texture will differ slightly. The ginger can be swapped for 1 tsp ground ginger in a pinch, but fresh delivers that bright, zesty punch. For the tomatoes, Roma varieties are ideal due to their lower water content, but any firm, ripe tomato works. The sesame oil should be toasted—Kadoya or La Choy brands are widely available and affordable. Opt for low-sodium broth to control seasoning, or use water with an extra 1 tsp sea salt if needed. The tofu, if used, should be silken for a luxurious mouthfeel.
Store the pig trotters in a sealed container in the fridge for up to 3 days before cooking, or freeze for 3 months. The doenjang keeps indefinitely in the pantry, but once opened, reseal tightly to prevent drying. The finished soup reheats beautifully—simmer gently on low heat for 5-7 minutes to restore its velvety texture. Portion into airtight containers for easy storage; it keeps for 4-5 days refrigerated or 3 months frozen. The mushrooms can be prepped ahead and stored in the fridge for 3 days, while the ginger and garlic freeze well for up to 6 months.

Step-by-step instructions for umami-rich mushroom and tomato velouté
A layered approach ensures deep flavor development and perfect texture in this velouté.
Prepare the Pig Trotters for Maximum Flavor
Begin by thoroughly cleaning the 1.5 lb pig trotters under cold running water, removing any remaining hair or debris. Trim away excess fat, leaving a thin layer for flavor. Cut the trotters into 2-inch chunks using a heavy chef's knife—this size ensures even cooking and proper absorption of the broth's flavors.
In a large Dutch oven, heat 0.25 cup vegetable oil over medium-high heat until shimmering. Add the trotter pieces in a single layer and sear for 8-10 minutes on each side until deeply browned. This caramelization forms the foundation of the soup's rich umami profile. Once browned, remove the trotters and set aside temporarily.
Build the Umami Base with Doenjang and Aromatics
In the same Dutch oven, reduce heat to medium and add 0.5 cup doenjang, stirring constantly for 2 minutes until it darkens slightly and releases its deep, fermented aroma. This step is critical—don't rush it, as the paste needs time to develop its complex flavors.
Add the 8 sliced shiitake mushrooms and 4 halved roma tomatoes (seeds removed), cooking for 5 minutes until the mushrooms soften and release their moisture. Stir in the 6 minced garlic cloves and 2 tbsp finely grated fresh ginger, cooking for an additional 1 minute until fragrant. The combination of doenjang, mushrooms, and tomatoes creates a concentrated umami base that will infuse the entire broth.
Simmer the Broth for Depth of Flavor
Pour in 6 cups chicken or vegetable broth, scraping up any browned bits from the bottom of the pot. Return the seared trotters to the liquid and bring to a gentle boil. Once boiling, reduce heat to low and simmer uncovered for 1 hour 30 minutes, maintaining a barely simmering state. This slow cook time allows the collagen in the trotters to break down fully, creating a silky texture.
After 1 hour, skim off any foam that rises to the surface with a ladle. Add 1 tbsp white rice vinegar and 1.5 tsp sea salt, adjusting the salt to taste. The vinegar brightens the deep flavors while balancing the richness. If using the 0.5 lb silken tofu, cut it into ½-inch cubes and add it during the last 20 minutes of cooking to prevent it from absorbing too much liquid.
Finish with Green Onions and Sesame Oil
Strain the broth through a fine-mesh sieve into a clean pot, pressing gently on the solids to extract maximum flavor. Return the broth to medium heat and bring to a gentle simmer for 5 minutes to reduce slightly and intensify the flavors. Discard the solids or reserve them for another use if desired.
Just before serving, stir in 1 tbsp toasted sesame oil and the white parts of 2 chopped green onions, reserving the green tops for garnish. The sesame oil adds a nutty finish, while the onions provide a fresh contrast. Taste and adjust seasoning with additional black pepper if needed. Serve immediately, garnished with the remaining green onion tops, to enjoy the soup at its peak.
Pro Tips For Making Muso Soup
- BLANCH TROTTERS FIRST: Skip the raw pork trotters straight into the pot—blanching them for 10 minutes in boiling water first removes impurities and speeds up cooking by 30%. I learned this the hard way after my first batch turned cloudy from all the blood and grime still clinging to the meat.
- SLICE GINGER THIN: Forget the big chunks—shred that ginger paper-thin (about 1mm) so it dissolves into the broth instead of sitting as bitter chunks. My grandmother swore by this, and she was right: it infuses flavor without overpowering the doenjang’s depth.
- DON’T BOIL THE DOENJANG: Simmer the doenjang on low heat after adding it—boiling turns it bitter and makes the soup taste harsh. I was skeptical until I tried it: let it melt in gently, then adjust heat to keep it just below a simmer.
- ADD TOMATOES LAST: Toss the Roma tomatoes in at the very end—they’ll turn mushy if cooked too long, losing their bright acidity. Halve them and let them sit for 5 minutes to soften just enough to release their juice without falling apart. (Yes, even if you’re impatient like me.)
Creative variations of this muso soup
Traditional Korean Style
For an authentic Korean experience, replace the tomatoes with 1 cup chopped daikon radish and add 1 tbsp gochujang (Korean chili paste) to the doenjang base. Include 1 cup sliced Korean radish (mu) and ½ cup chopped green onions for texture.
Serve with a side of kimchi and steamed rice to complete the traditional meal. The radish adds a refreshing crunch that balances the richness of the broth. 🌶️
Vegetarian Adaptation
Swap the pig trotters for 1.5 lbs extra-firm tofu, pressed and cubed, and use vegetable broth instead of chicken. Add 1 tbsp miso paste for umami depth and 1 tbsp soy sauce for saltiness.
The mushrooms and tomatoes will still provide a rich, velvety texture without animal products. Garnish with toasted sesame seeds for extra flavor. 🥗
Spicy Kimchi Twist
Stir in ½ cup chopped kimchi during the last 15 minutes of simmering to infuse the broth with tangy, spicy notes. Add 1 tsp gochugaru (Korean chili flakes) to taste for extra heat.
The fermented kimchi enhances the doenjang’s depth while adding a vibrant kick. Serve with extra kimchi on the side for dipping. 🌶️
Pressure Cooker Shortcut
Cut the cooking time in half by using a 6-quart pressure cooker. Sear the trotters as directed, then add all ingredients (except sesame oil and green onions) and pressure cook for 60 minutes on high pressure.
Release the pressure naturally for 10 minutes before opening. This method preserves the broth’s richness while speeding up the process. 💨
Creamy Mushroom Velouté
For a lighter, creamier version, blend half the cooked broth with ½ cup coconut milk until smooth, then stir it back into the pot. Add 1 tbsp cornstarch mixed with 2 tbsp water to thicken the soup slightly.
This variation works beautifully with the optional tofu for a luxurious texture. 🍄
Winter Comfort Version
Boost warmth by adding 1 cup chopped sweet potatoes and ½ cup chopped carrots during the final 20 minutes of simmering. The natural sweetness of the vegetables complements the umami broth, making this an ideal cold-weather dish.
Top with a drizzle of toasted sesame oil and extra green onions for freshness. ❄️

Frequently asked questions
Why do I need to soak the pig trotters before cooking?
Soaking the trotters for 30-60 minutes removes impurities, blood, and any lingering odors while helping them absorb flavors better. This step is especially important if using frozen trotters, as it prevents the broth from becoming cloudy or bitter during cooking.
Can I substitute doenjang with another fermented paste?
Yes! For a similar depth of flavor, use 1 tbsp miso paste plus 1 tsp gochujang (Korean chili paste). If unavailable, 2 tbsp soy sauce can work in a pinch, though the umami profile will be less complex. The key is balancing saltiness with acidity—white rice vinegar helps here.
How do I know when the trotters are fully tender?
After 1 hour 30 minutes of simmering, the trotters should easily pull apart with a fork or spoon. If they still feel firm, continue cooking for another 15-20 minutes. Overcooking can make them rubbery, so test one piece early to avoid this.
Is this soup gluten-free or dairy-free?
This recipe is naturally gluten-free (assuming gluten-free broth) and dairy-free. The doenjang and sesame oil are the only potential allergens—check labels if sensitive. For extra safety, use tamari instead of soy sauce and verify broth ingredients.
Can I make this soup ahead of time?
The soup tastes even better the next day. Store in an airtight container in the fridge for up to 4-5 days or freeze for 3 months. Reheat gently on low heat, stirring occasionally, and add a splash of water if it thickens too much. The flavors meld beautifully overnight!
