This easy roasted kabocha squash recipe is a delicious fall side dish! Sesame seeds, scallions, and a nutty sesame ginger dressing top the sweet squash.
Last fall, my brother-in-law, Josh, made the most amazing roasted kabocha squash for Thanksgiving. He cut it into wedges and cooked it with the skin still on. When it came out of the oven, the dense, bright orange flesh was smooth and creamy, with a sweet, nutty, and caramelized flavor. “What did you do to this?” I asked. “I just roasted it,” he said.
Also known as Japanese pumpkin, kabocha squash is a wonderfully versatile winter squash variety. In Japanese cooking, it’s often simmered in a flavorful dashi stock to make Kabocha no Nimono or fried and served as part of vegetable tempura. In Korea, it’s cooked into porridge and mashed into salad. Previously, I’ve blended it into pasta sauce and simmered it into soup.
But it wasn’t until I tried Josh’s Thanksgiving side dish that I really fell in love with roasted kabocha squash. It’s so simple to prepare, and it has such a rich flavor. Earlier this fall, I started topping it with sesame seeds, scallions, and my sesame ginger dressing to make a composed side dish, and I’m still obsessed with the combination. I hope you love it too!
How to Roast Kabocha Squash
If you’re not a fan of chopping and peeling winter squash, I don’t blame you. It’s not my favorite thing to do either! I do have good news, though: there’s no need to peel kabocha squash, as the skin is entirely edible. If your squash is particularly nubbly, you may want to trim away any brown, dry spots, but feel free to leave on the orange or green skin.
I also have a trick to make the squash easier to cut. Instead of attempting to slice it raw, I pop the whole, unpeeled squash in the oven for 10 minutes. This pre-bake makes it so much easier (and safer!) to slice.
After you pre-bake the squash, use a sharp knife to slice it in half lengthwise and scoop out the seeds.
Then, cut the seeded halves into 1 1/2-inch wedges.
Spread them in an even layer on a parchment-lined baking sheet and toss with generous drizzles of olive oil, salt, and pepper.
Transfer to a 425°F oven and roast the squash until it’s tender and golden brown, flipping halfway. That’s it!
Kabocha Squash Recipe Tips
- Save the seeds! Like pumpkin seeds, kabocha squash seeds are entirely edible. When roasted, they’re a delicious, protein-rich appetizer or snack. After you remove the seeds from the squash, pull off any orange, stringy flesh, rinse and dry the seeds, and toss them with a bit of olive oil and sea salt. Roast at 300°F for 35-45 minutes, stirring halfway, until golden brown and crisp. Yum!
- Don’t skimp on the oil. When roasted, different kabocha squash can vary in texture. Some are super-soft and creamy, sort of like a baked sweet potato, while others are a bit more dry and chalky. To prevent these squash from becoming too dry in the oven, make sure to coat them generously with oil. I use about 2 tablespoons for one medium kabocha squash.
Roasted Kabocha Squash Serving Suggestions
My favorite way to eat roasted kabocha squash is with sprinkles of sesame seeds, sliced scallions, and sesame ginger dressing. If I happen to have some on hand, I also add microgreens for a colorful finishing touch. Together, they create a simple side dish with a delicious mix of sweet, nutty, and savory flavors. Serve it with a bowl of miso soup and steamed rice, crispy sesame tofu, or whatever protein you like.
Not in the mood for sesame ginger? This roasted kabocha squash would be fantastic with one of these sauces instead:
- Gochujang Sauce
- Chipotle Honey Vinaigrette
- Easy Peanut Sauce
- Cilantro Lime Dressing
- Apple Cider Vinegar Dressing
Enjoy!

- 1 kabocha squash
- 2 tablespoons extra-virgin olive oil
- Sea salt and freshly ground black pepper
- Sesame Ginger Dressing, for drizzling
- ¼ cup chopped scallions
- Sesame seeds
- Microgreens
Instructions
- Preheat the oven to 425°F and warm the squash (whole) in the oven for 10 minutes, so that it’s easier to slice.

Divide the slices among the baking sheets, drizzle with the olive oil, sprinkle with salt and pepper, and roast for 25 to 30 minutes, flipping halfway, until golden brown and tender. (Note: the skin should be tender and it’s edible too.)
- Arrange the roasted squash on a shallow platter. Drizzle with the dressing, and sprinkle with the scallions, sesame seeds, and microgreens. Season to taste with more salt and pepper and serve.
Thank you for including the oven temperature and roasting time, as well as the instruction to use parchment paper. I purchased a package of pre-cut pieces of squash, and roasted them in olive oil at 425 degrees for 26 minutes, turning the squash half-way through. It came out so succulent, with “grill marks.” I only used olive oil, but the flavor and texture were outstanding!
Hi Kathy, that’s great to hear! I’m so glad you loved the squash.
The tip of pre-baking the kabocha squash prior to cutting is GOLD. Delicious!
A friend gave me a kabocha and this recipe sounded so good. Unfortunately, I didn’t love it.
This was very tasty. Thanks for the tip about precooking it before slicing, too! Genius!!
Hi Cindy, great to know that tip was helpful. I’m glad you enjoyed the squash!
Very tasty. I ate some right out of the oven. I sprinkled on top of the squash pieces with olive oil, salt and pepper, Baharat spice – an Arabic grouping of spices including paprika, Lampong pepper, cinnamon, cayenne, coriander, cumin, ginger, cloves, nutmeg and cardamom.
Hi Barb, that sounds delicious!
Awesome! This is definitely worth a try! I love the quality of the roasted kabocha squash. Thank you for sharing the recipe.
I hope you enjoy!
Dressing was delicious, presentation with micro greens and sesame seeds beautiful, roasted kombocha squash…yuck! The squashed turned out crumbly , as per your warning, despite using oil as directed and adding extra at the half way mark when flipped. I think I just picked a terrible squash. However do you pick a good one? This dish was made for Christmas dinner and was tossed after we all tried it. Everyone agreed the accompanying flavors were good but the texture of squash was awful. Would steaming the squash pre roasted have made a difference?
Oh darn! Getting a bad squash is so disappointing. My best tip for selecting one is to choose one that’s heavy for its size and has no visible soft spots or blemishes. I’m not sure how steaming, then roasting would work, but I think steamed kabocha squash would be lovely with this preparation! You could steam it until it’s fully tender and then top it with the dressing, etc.
Great way to cook kubocha, the sauce was amazing! Went very well with salmon.
So glad you loved it!
Absolutely delicious with the sesame ginger dressing. Huge hit at a dinner party!
Hi Tiffany, I’m so glad the recipe was a hit!
Great recipe !
It tastes amazing
This makes the absolute best squash I have ever had. The pre baking tip makes it so much easier and faster to chop up the squash. I didn’t have the ingredients to make the sauce, but still it was delicious and creamy so you just want to keep eating it.
I’m so glad you loved the squash!
This is my absolute favourite way to cook winter squash! We sprinkle sesame seeds and fresh thyme on the wedges.
I made it and it was amazing. I made a miso dressing since that’s all I had. It turned out perfect. I’ll make it again soon!
really nice way to treat squash! really like the scallions and sesame seeds, thank you
Perfect timing! I look forward to trying this!
Perfect timing! I got a kabocha in my subscription veggie box and it’s been staring at me from the counter for a couple of weeks. The sesame ginger dressing sounds great. I look forward to trying this!
