This crispy radish cake is a delightful twist on a classic dim sum favorite. Made with shredded radish and rice flour, it’s pan-fried to golden perfection for a crunchy outside and tender inside. Great for brunch or a cozy snack!
Introduction
I first tried radish cake at a dim sum restaurant years ago, and I was hooked instantly. It’s this beautiful balance of soft, slightly savory cake with a crispy golden crust that makes it so addictive. Over time, I experimented with making it at home, and what I love about this version is how simple the ingredients are and that you don’t need any fancy equipment. The trick I learned is to squeeze out excess moisture from the shredded radish before mixing it into the batter—this helps the cake hold together and crisp up perfectly when pan-fried. Also, using a mix of rice flour and cornstarch gives just the right texture—soft but firm enough to slice easily. When it’s done, you get this lovely contrast between the crunchy outside and the tender, flavorful inside. It’s perfect for a weekend brunch or a comforting snack any time of day. Honestly, it’s become a favorite in my family, and I think you’ll love it too!
What You'll Need
Approximately 8-inch cake, 4 servings
- 2 cups shredded daikon radish (about 1 medium radish)
- 1 cup rice flour
- 2 tablespoons cornstarch
- 1 ½ cups water
- 2 green onions, finely chopped
- 1 teaspoon salt
- ½ teaspoon white pepper
- 2 tablespoons vegetable oil for frying
How To Do It
Step 1
Start by peeling and shredding the daikon radish. Once shredded, place it in a clean kitchen towel or cheesecloth and squeeze out as much moisture as possible. This step is crucial because too much water in the radish will make the cake soggy and prevent it from setting properly. You want the radish to be damp but not dripping. Removing excess liquid ensures the cake holds together during cooking and crisps up nicely when fried.
⏱ Time: 10 minutes
✓ Doneness: Radish feels damp but not wet; no dripping liquid when squeezed
Step 2
In a mixing bowl, combine the rice flour, cornstarch, salt, and white pepper. Gradually add water while stirring to form a smooth, lump-free batter. The batter should be pourable but thick enough to coat the radish evenly. If you add water too quickly or skip stirring, lumps can form, which will affect the texture of your cake.
⏱ Time: 5 minutes
✓ Doneness: Smooth batter with no lumps, consistency like thick pancake batter
Step 3
Add the shredded radish and chopped green onions into the batter. Mix thoroughly to ensure the radish is evenly coated. This step ensures every bite has a good balance of radish and batter, giving the cake a uniform texture and flavor. Avoid overmixing, which can make the cake tough.
⏱ Time: 3 minutes
✓ Doneness: Evenly coated radish strands with batter, no dry spots
Step 4
Lightly oil an 8-inch round pan or cake pan and pour the mixture in, spreading it evenly. Steam the cake over boiling water for about 25 minutes. Cover the pan with foil to prevent water droplets from dripping onto the cake. Steaming cooks the batter gently, allowing it to set without drying out, which is key for the soft interior texture.
⏱ Time: 25 minutes
✓ Doneness: Cake is firm to the touch and a toothpick inserted comes out clean
Step 5
Once steamed, let the cake cool completely in the pan before removing. Cooling helps the cake firm up and makes it easier to slice without crumbling. If you try to slice it while still warm, it might fall apart.
⏱ Time: 30 minutes
✓ Doneness: Cake feels firm and cool to the touch
Step 6
Carefully invert the cake onto a cutting board and slice into 1-inch thick pieces. Use a sharp knife and clean the blade between cuts to keep slices neat. Even slices ensure consistent frying and texture.
⏱ Time: 5 minutes
✓ Doneness: Clean, even slices with no crumbling
Step 7
Heat vegetable oil in a non-stick skillet over medium heat. Once hot, add the radish cake slices in a single layer. Fry for about 3-4 minutes per side until golden brown and crispy. Don’t overcrowd the pan, or the slices will steam instead of crisp. The hot oil creates the Maillard reaction, giving the cake its signature crunch and color.
⏱ Time: 8 minutes
✓ Doneness: Golden brown crust with crispy texture on both sides
Step 8
Remove the fried radish cake slices and place them on a paper towel-lined plate to drain excess oil. This keeps the cakes crispy rather than soggy. Let them rest for a minute before serving.
⏱ Time: 2 minutes
✓ Doneness: No visible oil pooling, cakes remain crisp
Step 9
Serve the crispy radish cake warm with soy sauce or chili sauce on the side. The dipping sauces complement the mild savory flavor and add a little zing. Enjoy immediately for the best texture and flavor!
⏱ Time: Immediate
✓ Doneness: Warm, crispy, and flavorful bites with dipping sauce
Pro Tips
Always squeeze out excess water from the shredded radish before mixing.
Removing moisture prevents the cake from being soggy and helps it hold together during steaming and frying. Excess water can make the texture gummy and cause the cake to fall apart.
Use a mix of rice flour and cornstarch for the batter.
Rice flour provides tenderness while cornstarch adds firmness and crispness. This balance is key to achieving a soft interior with a crispy crust.
Steam the cake covered with foil to avoid water droplets falling on the surface.
Droplets can cause uneven texture and sogginess on the cake’s surface. Covering keeps the cake smooth and prevents water from diluting the batter.
Let the steamed cake cool completely before slicing.
Cooling firms up the cake, making it easier to slice cleanly without crumbling. Warm cake tends to be fragile and messy.
Fry the cake slices in hot oil without overcrowding the pan.
Crowding lowers the oil temperature and causes the cake to steam rather than crisp. Proper heat ensures a golden, crunchy crust.
Use a non-stick skillet for frying to prevent sticking and breaking.
A non-stick surface allows easy flipping and helps maintain the cake’s shape and texture during frying.
Serve the radish cake with soy sauce or chili sauce for added flavor.
Dipping sauces complement the mild, savory cake and add a spicy or salty kick, enhancing the overall eating experience.
Common Mistakes to Avoid
Not removing enough water from the radish
Why it happens Many cooks underestimate how watery daikon radish can be and skip or rush this step.
Fix Take the time to thoroughly squeeze the shredded radish in a clean towel. This ensures the cake sets firmly and crisps well, avoiding a soggy texture.
Skipping cornstarch or using too little
Why it happens Some think rice flour alone is enough, but it can lead to a cake that’s too soft and fragile.
Fix Include cornstarch as specified to add structure and crispness. It’s essential for slicing and frying success.
Steaming without covering the pan
Why it happens Not everyone knows that water droplets can fall onto the cake during steaming.
Fix Cover the pan with foil or a lid to prevent condensation from dripping onto the cake, which can cause uneven texture.
Trying to slice the cake while still warm
Why it happens Impatience or rushing can lead to the cake crumbling apart.
Fix Let the cake cool completely to firm up, making slicing neat and easy.
Overcrowding the pan when frying
Why it happens Trying to cook all slices at once to save time lowers oil temperature.
Fix Fry in batches with enough space to maintain heat, ensuring a crispy crust instead of greasy, soggy slices.
Variations
Vegetable Radish Cake
Add finely diced carrots and shiitake mushrooms to the batter for extra texture and flavor. This variation adds sweetness and umami, making the cake more complex and colorful.
Note: Adjust steaming time slightly to ensure the added vegetables cook through; the cake may be a bit moister so squeeze radish well.
Spicy Radish Cake
Mix in chopped fresh chili or a teaspoon of chili flakes into the batter for a spicy kick. Serve with a chili soy dipping sauce for heat lovers.
Note: Be cautious with chili quantity to balance heat without overpowering the mild radish flavor.
Gluten-Free Radish Cake
Use only rice flour and tapioca starch instead of cornstarch to keep it gluten-free. Tapioca starch helps maintain the crispness in frying.
Note: Texture may be slightly different—softer inside but still crisp outside when fried properly.
Vegan Radish Cake with Mushroom Broth
Replace water with mushroom broth for steaming and mixing to add depth of flavor. This adds earthiness and richness without changing the texture.
Note: Ensure broth is well strained to avoid lumps or sediment in the batter.
Pan-Fried Radish Cake Bites
Cut the steamed cake into small bite-sized squares and fry for a crispy appetizer perfect for parties or snacks.
Note: Fry on medium heat to avoid burning the small pieces; they cook faster than larger slices.

Storage & Tips
Room Temperature
The cooked radish cake can be kept at room temperature for up to 2 hours if covered to avoid drying out. Beyond that, it’s best refrigerated to maintain freshness and safety.
Refrigerator
Store leftover steamed or fried radish cake in an airtight container for up to 3 days. The texture will firm up and may lose some crispness if cold. Reheat in a skillet over medium heat to restore crispiness before serving.
Freezer
Freeze steamed radish cake wrapped tightly in plastic wrap and foil for up to 2 months. Thaw overnight in the refrigerator before frying. Avoid freezing after frying as texture degrades significantly.
Reheating
Reheat fried slices in a non-stick pan over medium heat for 3-5 minutes per side until hot and crispy again. Avoid microwaving, which makes the cake soggy. Adding a splash of oil helps restore crispness.
Make Ahead
You can steam and cool the radish cake 1-2 days ahead, then slice and fry fresh before serving. This saves time and ensures the best texture and flavor.
FAQ
Can I use regular flour instead of rice flour?
Regular wheat flour will change the texture, making the cake denser and less tender. Rice flour provides the characteristic soft but slightly chewy texture essential to radish cake. If you must substitute, use a mix of all-purpose flour and cornstarch, but expect a different result.
What if my radish cake falls apart when frying?
This usually means there’s too much moisture or not enough binder. Make sure to squeeze out excess water from the radish and use the correct ratio of rice flour and cornstarch. Also, let the cake cool completely before slicing and frying to help it hold together.
Can I make this recipe gluten-free?
Yes! Using rice flour and tapioca starch instead of cornstarch keeps it gluten-free. Tapioca starch helps maintain the crispiness when frying. Just avoid any added soy sauce that contains gluten or use tamari as a substitute.
How do I know when the cake is steamed fully?
The cake will be firm to the touch and a toothpick inserted in the center should come out clean without wet batter. Steaming too briefly results in a sticky, unset cake, while oversteaming can dry it out.
Can I bake the radish cake instead of steaming?
Baking isn’t traditional and will produce a different texture, likely drier and less tender. Steaming provides gentle, even cooking that preserves moisture and softness inside the cake.
What dipping sauces go best with radish cake?
Soy sauce, chili sauce, or a mix of soy and chili oil are classic choices. You can also try hoisin sauce or a garlic soy vinaigrette for different flavor profiles.
How do I store leftover fried radish cake?
Store fried slices in an airtight container in the fridge for up to 3 days. Reheat in a skillet to regain crispiness. Avoid microwaving as it makes the cake soggy.
Can I add other vegetables to the radish cake?
Yes, finely diced carrots, mushrooms, or dried shrimp are common additions that add flavor and texture. Just adjust steaming time slightly and ensure added ingredients are cooked or softened before mixing.
