In brief: First stabilize the pumpkin: cut a thin slice from the bottom so it rests on a flat surface, and cut by pressing down from above, never by prying. You don’t need to peel kabocha; its skin softens when cooked. Warm a hard Muscat pumpkin in the microwave or oven for a few minutes before cutting. A creamy soup made with one kabocha weighing around 1 kg serves 4 and is ready in 45 minutes.

Why pumpkins are tricky to cut
A pumpkin is round, hard, and likes to roll around on the table. Anyone who cuts it like a cucumber risks two things. The knife can slip on the hard rind and head toward your fingers. Or the blade can get stuck in the flesh, and you may start prying it sideways. Prying can break off a hard blade, and a thinner blade may even bend.
Safe cutting comes down to three rules: the pumpkin must sit steadily, pressure must be applied straight down from above, and the blade must not twist while cutting.
Kabocha, butternut, Muscat pumpkin: how they differ
Botanically, kabocha belongs to the species Cucurbita maxima, butternut and Muscat pumpkins to Cucurbita moschata, and spaghetti squash to Cucurbita pepo. In the kitchen, rind thickness matters more: the thicker it is, the more important the method below becomes.
What you’ll need
- A knife with a blade longer than 20 cm and tall enough not to twist while cutting. A small knife isn’t enough for a pumpkin and can get dangerously stuck in it.
- A large, stable cutting board, with a damp cloth underneath.
- A spoon for scooping out the seeds. The edge of an ordinary soup spoon is enough.
- A peeler, if peeling a butternut or Muscat pumpkin.
How to cut a pumpkin step by step
- Wash the pumpkin and, most importantly, dry it. A wet rind can slip under the blade and your fingers.
- Place a damp cloth under the cutting board so it doesn’t move on the counter.
- Cut off the stem and a thin slice from the opposite end so the pumpkin can stand on a flat surface.
- Place the blade in the middle of the pumpkin and press the handle straight down with your palm, smoothly and without jolts. Hold the pumpkin from the side with your other hand, away from the blade’s path.
- If the blade gets stuck, don’t pry or twist it. Pull it out in the same plane it went in, then cut from the other side or a little farther along.
- Scoop the seeds and fibrous center out of the halves with a spoon.
- Place the halves cut-side down so they sit steadily, then cut them into wedges 3–4 cm wide.
- Place the wedges on their sides and cut them into cubes. For soup, 2–3 cm is enough.

When the pumpkin is too hard
With a nutmeg pumpkin or an older pumpkin with wood-hard skin, it’s worth softening it first. Warm the whole pumpkin by pricking it several times with a fork to prevent steam pressure from building up inside, then microwave it for 2–3 minutes. Alternatively, bake it for 10 minutes at 180 °C. The skin will soften, letting the blade pass through without forcing it. The inside will stay raw; only the skin and the thin layer beneath it will soften.
What to use to cut pumpkin
Pumpkin knife: SARACEN® PRO
SARACEN® is a kitchen knife with a saber-shaped blade made of 67-layer Damascus steel. Its handle and center of gravity are shifted toward the center of the knife, above the blade. This directs hand pressure straight down into the blade rather than at an angle, and keeps your knuckles from hitting the cutting board as you slice.
For pumpkin, you need a blade long enough to pass through its full width and tall enough not to lean sideways while cutting. SARACEN® PRO has a wider, taller blade designed for both slicing and chopping. For a whole Hokkaido pumpkin, choose the 218 mm length; the shorter 175 mm version is enough for wedges and cubes. Because the handle sits above the blade, pressure from your palm goes straight down into the cut, so you don’t need to press the spine of the blade near the tip with your other hand, as you would with a classic knife.
One caveat: hard 60 ± 2 HRC steel holds its edge for a long time, but doesn’t tolerate twisting while cutting. Prying could chip the edge, just like striking a bone, so follow the rule in step five.
The article Why the SARACEN® knife has a handle positioned differently from other knives explains why SARACEN has a handle above the blade and how this changes the pressure applied.
Recipe: Creamy Hokkaido Pumpkin Soup
Hokkaido pumpkin has sweet, slightly nutty flesh, and since it doesn’t need to be peeled, this soup comes together quickly. Ginger adds freshness, while coconut milk or cream makes it smooth.
4 servings · prep 20 minutes · cook 25 minutes · total 45 minutes
Ingredients
- 1 Hokkaido pumpkin (about 1 kg)
- 1 large onion (about 150 g)
- 1 carrot (about 100 g)
- 2 cloves of garlic
- a piece of fresh ginger (about 2 cm)
- 2 tablespoons butter or olive oil
- 1 L vegetable stock
- 200 ml coconut milk or cooking cream
- salt and freshly ground pepper
- a pinch of ground nutmeg
- for garnish: pumpkin seeds and a few drops of pumpkin oil
Method
- Cut the pumpkin as described above, scoop out the seeds, and cut it, skin and all, into 2–3 cm cubes.
- Finely chop the onion (see the article How to finely chop an onion for instructions), slice the carrot, and finely chop the garlic and peeled ginger.
- Melt the butter in a large pot and sauté the onion in it for about 5 minutes, until translucent. Add the garlic and ginger and sauté them with the onion for a minute.
- Add the pumpkin and carrot, sauté for 2–3 minutes, pour in the stock, and cook covered for 15–20 minutes, until the pumpkin is completely soft.
- Blend the soup until smooth with an immersion blender.
- Stir in coconut milk or cream and heat the soup through, but don’t let it boil. Season with salt, pepper, and nutmeg.
- Serve with toasted pumpkin seeds and a few drops of pumpkin seed oil.
Tips and variations
- Don’t throw away the pumpkin seeds. Rinse and dry them, toss with a little oil and salt, and bake for 12–15 minutes at 180 °C.
- For a more intense flavor, roast the pumpkin and carrot first. Toss the cubes with oil and roast for 25 minutes at 200 °C, then add them to the pot instead of frying them.
- Adjust the consistency with stock. Thin out thick soup, or let watery soup simmer uncovered for a while.
- The soup will keep in a sealed container in the fridge for 3 days. It’s best frozen without cream or coconut milk; add those when reheating.
- If you don’t like ginger, replace it with a pinch of curry powder or smoked paprika.
Frequently asked questions
Does Hokkaido pumpkin need to be peeled?
Not necessarily. Hokkaido pumpkin skin is thin and softens when cooked, so it blends into the soup and is edible. It’s worth peeling butternut and nutmeg pumpkins, as their skin stays tough.
How do you cut up a hard pumpkin?
First stabilize the pumpkin by slicing off the bottom, then cut straight down, applying pressure from above without twisting the blade. For a very hard pumpkin, pierce it all over and warm it for 2–3 minutes in the microwave or 10 minutes in the oven at 180 °C; the skin will soften.
What kind of knife should you use to cut pumpkin?
Use a knife with a blade longer than 20 cm and tall enough not to twist while cutting. For example, the SARACEN PRO 218 mm has a wider blade for slicing and chopping. A small knife gets stuck and slips in the pumpkin.
What should you do if the knife gets stuck in the pumpkin?
Don’t pry or twist. Pull the blade out along the same path it went in, then cut from the other side or a little way over. Prying can chip the hard blade.
How long does pumpkin soup take to cook?
After adding the stock, cook for 15–20 minutes, until the pumpkin softens. The whole hokkaido pumpkin soup takes about 45 minutes, including chopping.
What can you use instead of cream in pumpkin soup?
Coconut milk, which goes well with pumpkin and ginger. If you use oil instead of butter and vegetable stock, the soup contains no animal products.
Can you freeze pumpkin soup?
Yes, ideally without cream or coconut milk. Add those when reheating so the soup doesn’t separate after thawing.
One pumpkin weighing around a kilogram is enough to make soup for four, and it takes 45 minutes. Only the hard-shell nutmeg pumpkin takes longer; it’s best to warm it for a few minutes before cutting.
