Radish soup might not be the first thing that comes to mind when you think of comfort food, but it should be. I first tried a version of this soup at a friend’s house years ago, and I’ve been hooked ever since. It’s warm, filling, and comes together faster than you’d think for something that tastes this good.
What I love about this recipe is how simple it is. You’ve probably got most of these ingredients already – beef, radish, mushrooms, and a few basic seasonings. The radish cooks down into something soft and mellow, completely different from the crunchy salad topping you might be used to. And the broth? It gets this deep, savory flavor that makes it hard to stop at just one bowl.
This is one of those soups I make on a weeknight when I want something hearty without spending an hour in the kitchen. It’s also great for using up that radish sitting in your fridge. You know the one I’m talking about.
Why You’ll Love This Radish Soup
- Quick and easy – This soup comes together in just 30-45 minutes, making it perfect for busy weeknights when you want something warm and satisfying without spending hours in the kitchen.
- Light yet filling – The combination of tender beef and radish creates a comforting soup that’s hearty enough to satisfy without feeling heavy.
- Simple ingredients – You only need a handful of basic ingredients to make this flavorful soup, and most of them are probably already in your pantry or easy to find at your local grocery store.
- Healthy comfort food – This soup is naturally low in calories and packed with nutrients from the radish and mushrooms, so you can feel good about what you’re eating while still enjoying a cozy, warming meal.
What Kind of Radish Should I Use?
Korean radish is the traditional choice for this soup and has a slightly sweeter, milder flavor than regular radishes, but daikon radish works just as well and is easier to find at most grocery stores. Both varieties hold up nicely during cooking and won’t turn mushy, which is exactly what you want in a soup like this. If you can’t find either one, you could even use regular red radishes in a pinch, though they’ll have a bit more peppery bite to them. When shopping, look for radishes that feel firm and heavy for their size, and avoid any that have soft spots or look dried out.
Options for Substitutions
This soup is pretty forgiving when it comes to swaps, so here are some options if you need them:
- Korean radish or daikon: Korean radish is really the star here, so I’d recommend sticking with it if possible. If you can’t find it, daikon is your best bet as it has a similar texture and mild flavor. Regular red radishes won’t work well since they’re too small and have a different taste.
- Beef brisket or chuck: Both cuts work great because they get tender during cooking. You can also use short ribs or even pork shoulder if you prefer. Just keep the cooking time the same to let the meat get nice and tender.
- Sesame oil: Regular vegetable oil or olive oil can work in a pinch, but you’ll lose that nutty, toasted flavor that sesame oil brings to the soup.
- Shiitake or cremini mushrooms: Since these are optional anyway, feel free to skip them or use whatever mushrooms you have on hand – button mushrooms or oyster mushrooms both work fine.
- Low-sodium soy sauce for soups: Regular soy sauce works too, but start with less (about 1 tablespoon) since it’s saltier. You can always add more to taste.
Watch Out for These Mistakes While Cooking
The biggest mistake when making radish soup is skipping the step of browning the beef properly – if you rush this part or overcrowd the pot, the meat will steam instead of sear, which means you’ll miss out on the deep, savory flavor that makes this soup special.
Another common error is not removing the foam that rises to the top during cooking, as leaving it in can make your broth cloudy and give it a slightly bitter taste.
Don’t add the soy sauce too early in the cooking process – wait until the end so you can taste and adjust the seasoning properly, since the broth reduces as it cooks and you might end up with an overly salty soup.
Finally, cut your radish pieces evenly so they cook at the same rate, and remember that radish should be tender but still have a slight bite to it, not mushy.
What to Serve With Radish Soup?
This radish soup is hearty enough to be a meal on its own, but I love serving it with a bowl of steamed white rice on the side – it’s perfect for soaking up all that savory broth. If you want to make it a bigger spread, add some Korean side dishes like kimchi, seasoned spinach, or cucumber salad to round out the meal. A simple egg roll or some pan-fried dumplings also pair really well with this soup, especially on a cold day when you want something warm and filling. For a lighter option, serve it alongside a crisp lettuce salad with a sesame dressing that complements the soup’s Asian flavors.
Storage Instructions
Store: This radish soup actually tastes even better the next day after all the flavors have had time to mingle. Keep it in an airtight container in the fridge for up to 4 days. The radish will continue to soak up the broth, making it even more flavorful.
Freeze: You can freeze this soup for up to 3 months in freezer-safe containers. Just leave a little room at the top since liquids expand when frozen. I like to portion it out into individual servings so I can grab just what I need for a quick meal.
Reheat: Warm the soup gently on the stovetop over medium heat, stirring occasionally until heated through. You can also microwave it, but I prefer the stovetop since it heats more evenly. Add a splash of water if it’s gotten too thick after storing.

Ingredients
- 1 1/2 tbsp sesame oil
- 8 oz beef (sliced into thin 1/8-inch bite-sized strips)
- 12 oz radish (peeled and cut into 1-inch squares, about 1/4-inch thick)
- 7 cups water
- 1 1/2 tbsp garlic (freshly minced)
- 6 oz mushrooms (Baby Bella preferred)
- 2 green onions (sliced diagonally into 1-inch pieces)
- 2 1/2 tbsp soy sauce
- 1 tsp fish sauce
- 1/4 tsp ground black pepper
- salt to taste
Step 1: Prepare Mise en Place
- 12 oz radish
- 8 oz beef
- 1 1/2 tbsp garlic
- 6 oz mushrooms
- 2 green onions
Peel the radishes and cut them into 1-inch squares approximately 1/4-inch thick.
Slice the beef into thin 1/8-inch bite-sized strips.
Mince the garlic freshly.
Slice the mushrooms into bite-sized pieces.
Cut the green onions diagonally into 1-inch pieces.
Having everything prepped before cooking ensures smooth execution and prevents the soup from overcooking while you’re still cutting ingredients.
Step 2: Sear the Beef
- 1 1/2 tbsp sesame oil
- 8 oz beef
Heat the sesame oil in a large pot over medium-high heat until shimmering.
Add the sliced beef and cook for 2-3 minutes, stirring occasionally, until the meat is mostly cooked through but still slightly pink in the center.
The beef will finish cooking in the broth, so don’t overcook it at this stage.
I find that searing the beef first builds a deeper flavor foundation for the entire soup.
Step 3: Build the Broth Base
- 12 oz radish
- 8 oz beef
- 7 cups water
- 1 1/2 tbsp garlic
Add the prepared radish squares from Step 1 to the pot with the seared beef and stir constantly for 2-3 minutes to lightly toast them.
This helps develop the radish’s subtle sweetness.
Pour in the 7 cups of water and bring to a boil over high heat.
Once boiling, add the minced garlic, reduce heat to medium, and gently simmer for 15-20 minutes, skimming off any foam that rises to the surface.
This simmering time allows the radish to become tender and infuses the broth with deep flavor.
Step 4: Add Mushrooms and Green Onions
- 6 oz mushrooms
- 2 green onions
Add the sliced mushrooms and green onions to the pot and simmer for 5-7 minutes until the mushrooms are tender and cooked through.
The mushrooms will absorb the aromatic broth and release their umami-rich flavors into the soup.
Step 5: Season and Finish
- 2 1/2 tbsp soy sauce
- 1 tsp fish sauce
- 1/4 tsp ground black pepper
- salt to taste
Remove the pot from heat and stir in the soy sauce and fish sauce until fully combined.
Season with ground black pepper and taste, adding salt as needed.
I like to add the soy and fish sauce at the end rather than during cooking because it allows me to adjust the saltiness to my preference without the flavors becoming muted through prolonged simmering.
Serve hot and enjoy the clean, savory broth.
