Kabocha (pronounced Kab-BOH-chah), often called Japanese pumpkin, is a winter squash with a mildly sweet flavor and smooth texture. Roasted kabocha resembles butternut squash or sweet potato, but its orange flesh is a bit denser and more substantial. Leaving the peel on saves time and boosts fiber and nutrients.
This recipe is low-effort and high-reward: halve the squash, remove seeds, slice into wedges, toss with olive oil, salt, pepper and herbs, and roast for about 25 minutes until fork tender. Use the base savory version or try the sweet maple-cinnamon variation in the Variations section below. The velvety flesh and mild nutty sweetness make roasted kabocha a favorite for fall and winter meals.

Ingredients

Kabocha squash
Use a whole kabocha: halve it, remove seeds, and slice into wedges. The peel becomes tender and edible when roasted. If you prefer, peel before or after roasting.
If kabocha isn’t available, substitute with butternut, acorn, delicata, or delica squash.
Garlic
Use crushed fresh garlic for a subtle aroma or garlic powder for an even coating and milder texture.
Herbs
Fresh rosemary, sage, or thyme pair wonderfully with kabocha—choose one or combine a couple for depth.
Salt and Pepper
Sea or kosher salt and freshly ground black pepper are the basic seasoning. Add red pepper flakes or chili powder if you like a little heat.
Olive oil
Use good quality extra virgin olive oil for flavor and stability at oven temperatures. Regular olive oil or avocado oil are acceptable alternatives.

Instructions
Preheat the oven to 400°F (200°C). Line a baking sheet with parchment paper.
Wash and scrub the kabocha, dry it, and carefully cut it in half. Scoop out the seeds with a spoon.
Place a squash half cut-side down on a cutting board and slice into about 1/3 inch (0.8 cm) wedges with a sharp knife.

Arrange the slices in a single layer on the prepared baking sheet without overlapping. A standard sheet fits roughly 2 pounds of squash.

Drizzle with olive oil and season with garlic powder (or crushed garlic), salt, black pepper, and chopped herbs such as rosemary and sage. Toss gently to coat.

Bake at 400°F (200°C) for about 25 minutes, until the slices are fork tender and lightly browned at the edges.

Serve warm as a side, or use the roasted squash in soups, pasta, gnocchi, ravioli, salads, or grain bowls.

Variations
Peeled roasted kabocha squash
After halving and seeding, lay the squash flat and remove the peel with a sharp knife. Cut into slices or cubes, toss with oil, salt, pepper, crushed garlic, sage and rosemary (or chopped onion), and roast at 400°F (200°C) for about 25 minutes.

Cinnamon and maple syrup roasted kabocha
For a sweet version, toss slices with olive oil and maple syrup, then sprinkle a teaspoon of cinnamon, a pinch of grated nutmeg, a bit of salt and pepper. Roast 25 minutes until tender — perfect for holiday sides or a cozy weeknight treat.
Serving suggestions
Serve roasted kabocha as-is or finish with fresh herbs or a squeeze of lemon. It pairs well with protein-rich mains and grain bowls.
Ideas to serve alongside:
- Pan-fried tofu with mushrooms
- Lentil pasta with fresh herbs
- Tofu with pizzaiola sauce and sautéed greens
- Marinated tofu over rice or cauliflower rice
As a light lunch, add kabocha wedges to salads such as chickpea salad, lentil tabbouleh, cauliflower-lentil salad, or a green bean salad for holiday menus.
For a quick 5-minute lunch, serve roasted kabocha with a tofu scramble on toasted bread for a balanced, protein-rich meal.
Storage
Store leftover roasted squash in an airtight container in the refrigerator for up to 3 days. Reheat gently in a preheated oven, air fryer, or microwave.
