Sweet & Spicy Korean Fried Cauliflower
Korean fried cauliflower turns a humble vegetable into something you’ll want to make again and again. Crispy battered florets get tossed in a sticky gochujang sauce that’s equal parts sweet, savory, and gently spicy.
It all happens in one pan on the stovetop, and the sauce comes together in about two minutes. Serve it over rice for a fast weeknight dinner or pile it on a platter as a shareable appetizer.
Why I Keep Coming Back to This Korean Fried Cauliflower
The batter stays light and shatteringly crisp, thanks to a splash of sparkling water. Even after the sauce hits, the florets hold their crunch for a few gloriously messy minutes at the table.
That sauce is the real reason I make this. Gochujang gives it a deep, fermented warmth, honey rounds out the edges, and a tiny pour of sesame oil pulls everything together without making it greasy.
It’s one of those dishes that feels like a treat without a long ingredient list. I always have the staples on hand, so it’s my go-to when I want something bold but don’t want to leave the house.
Ingredients
- 1 large head cauliflower (about 2 lbs): cut into bite-sized florets
- ¾ cup all-purpose flour: spooned and leveled, not scooped
- ¼ cup cornstarch: keeps the batter light
- 1 tsp baking powder: for extra lift
- ½ tsp kosher salt
- ¾ cup cold sparkling water: the carbonation makes the coating airy
- Vegetable oil, for frying: about 1 inch deep in your pan
- 3 tbsp gochujang (Korean chili paste): the heart of the sauce
- 2 tbsp low-sodium soy sauce
- 1½ tbsp honey: or maple syrup for vegan
- 1 tbsp rice vinegar
- 2 tsp toasted sesame oil
- 2 cloves garlic, finely grated
- 1 tsp grated fresh ginger
- Toasted sesame seeds and thinly sliced scallions, for garnish
Variations / Substitutions
- Make it gluten-free: Swap the flour for a 1-to-1 gluten-free blend and use tamari instead of soy sauce. The batter will still fry up crisp.
- Dial the heat up or down: Use a mild gochujang (or even sriracha) for less warmth, or add a pinch of gochujang if you like more kick.
- Go fully vegan: The honey is the only non-vegan ingredient here. Maple syrup or agave both work beautifully.
- Try a different vegetable: This same batter and sauce are great on broccoli florets or quartered small mushrooms. Adjust the fry time slightly for each.

How to Make Korean Fried Cauliflower
Step 1: Stir Together the Sauce
In a small bowl, whisk together the 3 tbsp gochujang, 2 tbsp soy sauce, 1½ tbsp honey, 1 tbsp rice vinegar, 2 tsp sesame oil, the grated garlic, and the grated ginger. Set it near the stove so it’s ready when the cauliflower comes out of the oil.
The sauce should be thick enough to cling but thin enough to coat everything without glooping. If it feels too stiff, a teaspoon of warm water loosens it right up.
Step 2: Cut and Dry the Cauliflower
Trim the leaves and core from the cauliflower, then cut it into florets about the size of a golf ball. Lay them out on a clean towel and pat very dry. Any water left on the surface will steam in the oil and ruin the crisp shell you’re about to build.
Don’t skip the drying step, even if the florets look dry. That little bit of surface moisture is the number one enemy of crunchy fried food.
Step 3: Whisk the Batter
In a mixing bowl, combine the ¾ cup flour, ¼ cup cornstarch, 1 tsp baking powder, and ½ tsp salt. Pour in the ¾ cup cold sparkling water and whisk just until smooth. A few small lumps are fine; overmixing can make the batter tough.
The batter should be slightly thinner than pancake batter and fall in ribbons from the whisk. If it thickens as it sits, stir in another tablespoon of sparkling water before dipping.
Step 4: Fry the Florets
Pour enough vegetable oil into a heavy-bottomed pot or deep skillet to reach about 1 inch up the side. Heat it over medium-high until it reaches 350°F (180°C). If you don’t have a thermometer, drop in a tiny bit of batter; it should sizzle and rise to the top immediately.
Working in batches, dip the dry florets into the batter, letting the excess drip off, then carefully lower them into the hot oil. Fry for 3 to 4 minutes, turning once, until deep golden and impossibly crunchy. Lift them out with a slotted spoon and drain on a wire rack or paper towels. Keep finished batches warm in a 200°F (95°C) oven while you fry the rest.
Step 5: Coat and Serve
While the cauliflower is still hot from the oil, transfer it to a large bowl. Pour the gochujang sauce over the top and toss gently with a spatula until every piece is glazed. Sprinkle generously with toasted sesame seeds and sliced scallions, then get it to the table immediately.
Serve it over steamed rice for a full meal, or mound it on a plate with extra napkins. The coating is at its loudest crackle right after tossing, so that first bite is a quick race.
Tips for the Crunchiest Cauliflower
- Keep the batter cold and the oil hot.: Sparkling water right from the fridge and a steady 350°F (180°C) give you the crispest shell. If the oil temperature dips, the florets soak up grease instead of frying.
- Use a wire rack instead of paper towels for draining.: Air can circulate underneath and prevent the bottom from going soggy while you fry the next batch.
- Don’t crowd the pot.: Fry in two or three rounds so the oil temperature doesn’t plummet. Too many florets at once means pale, greasy cauliflower.
- Make the sauce a day ahead.: It keeps well in the fridge, and the garlic and ginger actually mellow and deepen overnight.
Storing and Reheating Korean Fried Cauliflower
Leftovers lose their crunch, but they’re still delicious. Store any extra in an airtight container in the fridge for up to 3 days. To bring back some crispness, spread the sauced florets on a baking sheet and reheat in a 400°F (200°C) oven for 5 to 7 minutes, or air fry at 375°F (190°C) for 3 to 4 minutes.
What to Serve with Korean Fried Cauliflower
A bowl of short-grain white rice is the simplest side, soaking up any extra sauce. Quick cucumber pickles cut through the richness with their sharp, cold crunch. For a full spread, add a fried egg with a runny yolk and a spoonful of kimchi on the side.
Frequently Asked Questions
Can I bake this instead of frying?
You can, but the texture will be softer. Bake battered florets on a greased sheet at 425°F (220°C) for 20 to 25 minutes, flipping halfway, then toss with the sauce.
How do I get the batter to stick?
Thoroughly dry the cauliflower and dip it immediately before it hits the oil. Even a little moisture will cause the batter to slide off in the pan.
Is there a way to make this less spicy?
Gochujang varies in heat. Use a mild variety or reduce the amount to 2 tablespoons and add an extra drizzle of honey to balance it out.
Can I use an air fryer?
Yes. Spray the battered florets with oil and air fry at 400°F (200°C) for 12 to 15 minutes, shaking the basket once. Toss in sauce right after.
