Takenoko Tempura — Fresh Bamboo Shoot Tempura from the Garden
Takenoko Tempura — Fresh Bamboo Shoot Tempura from the Garden
Every spring in Kyushu, bamboo shoots push up through the ground and need to be harvested before they get too big. This year I dug up a batch from our garden — and the first thing I made with them was tempura.
Takenoko tempura (たけのこの天ぷら) is one of the best ways to eat fresh bamboo shoots. The outside gets light and crispy, while the inside stays tender with that distinctive bamboo flavor — slightly sweet, earthy, and completely unlike the canned version. It’s a seasonal dish that only works properly with fresh bamboo shoots, which makes it feel special every time.
Starting from Fresh Bamboo Shoots
If you’re using fresh bamboo shoots, you need to remove the bitterness before cooking — this is called aku-nuki (アク抜き), or removing the harshness. Fresh bamboo shoots contain oxalic acid which makes them bitter and slightly astringent if you cook them straight.
The traditional method is to boil them with rice bran (糠, nuka) and dried chilli peppers. The bran absorbs the bitterness and the chilli helps neutralise it.
How to Boil Fresh Bamboo Shoots
- Peel the outer layers of skin from the bamboo shoots
- Place in a large pot and cover with water
- Add a large handful of rice bran (nuka) and 1–2 dried chilli peppers
- Bring to a boil, then simmer for 1–1.5 hours until a skewer goes through easily
- Leave to cool in the water, then rinse well
After boiling, the bamboo shoots are mild, tender, and ready to cook with. Slice them in half to check — the inside should be pale yellow and completely soft all the way through.
If you can’t get fresh bamboo shoots, use vacuum-packed or water-packed bamboo shoots — skip the boiling step and go straight to slicing.
Ingredients (Serves 2)
- 300g bamboo shoots (boiled fresh, or water-packed)
- 1 tablespoon plain flour (for dusting)
- Vegetable oil, for frying
- Salt, to serve (optional)
Batter
- 3 tablespoons plain flour (or use pre-mixed tempura flour)
- 2 tablespoons potato starch (katakuriko)
- 80ml cold water
How to Make It
Step 1: Slice and Dust
Slice the bamboo shoots into pieces about 1cm thick. Pat them dry thoroughly with paper towels — any moisture on the surface will make the batter fall off and cause the oil to splatter.
Dust each piece lightly with plain flour. This helps the batter stick to the surface of the bamboo shoot.
Step 2: Make the Batter
Mix the flour, potato starch, and cold water together until just combined. Don’t overmix — lumps are fine. The batter should be thin and runny, not thick. Cold water is important: it keeps the batter light and prevents it from becoming heavy and doughy.
Step 3: Fry
Heat the oil to 170–180°C (340–355°F) — a deep-fry thermometer takes the guesswork out of this. Dip each piece in the batter and lower it carefully into the oil. Fry for 2–3 minutes, turning once, until the batter is light golden and crispy. Bamboo shoots are already cooked, so you’re just frying the coating — don’t over-fry or the batter will get too dark.
Fry in small batches so the oil temperature stays stable.
Step 4: Serve
Drain on a wire rack. Serve immediately with a pinch of salt or a dipping sauce (tentsuyu — a mix of dashi, soy sauce, and mirin — is traditional). The tempura is at its best right out of the oil while the coating is still crispy.
Tips from My Kitchen
- Dry the bamboo shoots thoroughly. Moisture is the enemy of crispy tempura. Pat them dry before dusting with flour.
- Use cold water for the batter. This is the key to light, crispy tempura. Some cooks use ice water or even sparkling water.
- Don’t overmix the batter. A lumpy batter is actually better — overmixing develops the gluten and makes the coating heavy.
- Fresh is completely different from canned. If you ever get access to fresh bamboo shoots in spring, use them. The flavor and texture are in a different league.
- Serve immediately. Tempura softens quickly as it sits. Eat it straight from the oil.
If you enjoy this style of light, crispy frying, try my tori ten (Oita-style chicken tempura) next — it uses the same batter technique with chicken. Agedashi tofu is another excellent option that uses a similar dashi-based dipping sauce. For crispy fried fish, my fish karaage is worth a try too.
Where to Buy Japanese Ingredients
If you can’t find these at a local Asian grocery store, here’s what I use:
- Potato starch (katakuriko) — adds crispiness to the batter that plain flour alone can’t achieve
- Soy sauce — for the dipping sauce
- Mirin — for the dipping sauce

Frequently Asked Questions
Do I have to boil fresh bamboo shoots first?
Yes, always. Raw bamboo shoots are bitter and harsh, and boiling them — traditionally with rice bran and a dried chili — removes that. If you’re using vacuum-packed or canned pre-boiled bamboo shoots, that work is already done and you can go straight to slicing.
What makes tempura batter light?
Cold water, minimal mixing, and using it immediately. Lumps in the batter are fine and even desirable — overmixing develops gluten and gives you a heavy, bready coating. Some people add a spoonful of vodka or use sparkling water, both of which work by the same logic.
Why is my tempura soggy?
Oil that isn’t hot enough, or a crowded pot. Each piece dropped in lowers the oil temperature, so fry in small batches and let the oil recover between them. Drain on a rack rather than paper towels so steam escapes from underneath.
Can you make tempura in an air fryer?
Not really — proper tempura batter needs to hit hot oil to set. An air fryer gives you a dry, patchy coating. If you want a lighter version, use a thin dusting of starch rather than a wet batter.
What do you serve tempura with?
A dipping broth (tentsuyu) with grated daikon, or simply salt — a good sea salt or matcha salt suits bamboo shoots particularly well, since the flavor is delicate and a heavy broth can bury it.
