My roasted kabocha squash gets a tamari-maple-ginger glaze halfway through roasting — first you get color on the wedges, then the glaze turns glossy and caramelized in the final 10 minutes. I fell for kabocha on a layover in Japan years before it showed up in every US grocery store, and this is the recipe that stuck.
Double roast + 3-ingredient glaze = the most delicious kabocha!
I first had kabocha squash in a Japanese curry during a layover from Asia. Locals call it Japanese pumpkin, and it shows up everywhere there — roasted with soy glaze, simmered in miso broth, tempura-fried in bento boxes. The dense, creamy texture and chestnut-like sweetness hooked me immediately.
Back home, I wanted that same balance: earthy caramelized squash with something salty, gingery, and just sweet enough on top.
The technique is a double roast. Ten minutes at 400°F to get color on the wedges, then brush with a quick glaze of tamari, maple syrup, and ground ginger, and back in for another 10 minutes. The glaze lacquers onto the already-hot surface and turns glossy without burning. I tried glazing from the start and the sugars scorched before the squash was tender. The two-stage approach fixes that.

Key ingredients and why they matter
To roast kabocha squash, you’ll need: kabocha squash (approximately a pound) and olive oil. I’ve seasoned this recipe with maple syrup, tamari, ground ginger, sesame seeds (for garnish), and salt and black pepper.
Full ingredient list and detailed instructions in the recipe card.
- Kabocha squash: The star — sweet, buttery, and a little nutty. Look for one that’s deep green and heavy for its size; that means it’s ripe and full of flavor.
- Olive oil: Helps caramelize the edges and carry the glaze’s flavor. You don’t need a fancy bottle, but avoid anything too bitter.
- Soy sauce: Adds savory depth and balances the squash’s natural sweetness. Use tamari to keep it gluten-free.
- Maple syrup: A touch of sweetness that amplifies the kabocha’s natural sugar and creates that golden, lacquered finish.
- Ginger: Fresh or ground, it cuts through the richness and adds warmth — don’t skip it.
- Sesame seeds: Toasted and scattered at the end for crunch and a hint of nuttiness.
- Variations:
- Japanese-inspired flavor profile with soy sauce, ginger, and sesame seeds (which is what this recipe uses). You can also try roasted kabocha squash with my Japanese sesame dressing! Absolutely delicious.
- Korean-inspired flavor profile with a gochujang + tahini marinade. Check out the marinade used in my roasted whole cauliflower recipe!
TIPS & TRICKS
Shruthi’s top tips
Don’t glaze from the start. The sugars in maple syrup will scorch before the squash is tender. Roast plain for 10 minutes first, then brush the glaze on for the final 10.
Leave the skin on. Kabocha skin is edible and softens completely during roasting. It also helps the wedges hold their shape.
Toast the sesame seeds separately if yours aren’t pre-toasted — raw sesame seeds on top of hot squash won’t toast enough to develop flavor.
Picking the right kabocha squash
Look for one that’s round with hard, dark green skin — it may have a yellow spot where it ripened on the ground, and that’s fine. Pick it up: it should feel heavy for its size, which means it’s ripe and dense inside. Check the stem for mold. Bumpy skin is normal; soft spots are not. Find it at Asian grocery stores or increasingly in the regular squash section at most supermarkets in fall.
How to cut kabocha squash
Kabocha squash is NOT.OH.RIOUS. for its hard outer shell. So, please be careful while you’re cutting it in half!
A few things that help: use a sharp, heavy chef’s knife — not a paring knife. I’ve had this chef’s knife for almost 10 years and it’s the single best kitchen investment I’ve made. Slice off the top and bottom first so you have flat, stable surfaces. Cut in half top to bottom, scoop out the seeds, then slice into 1½-inch wedges.
If the shell is really fighting you, poke a few holes in the surface and microwave for 1–2 minutes until it softens slightly. Then cut. This trick has saved me more than once.
How to roast kabocha squash
- Use a sharp knife to cut the squash in half down the middle carefully. Then use a spoon to take off the seeds inside each half.
- Slice into thick slices (~1 ½ inch wedges).
- Preheat the oven to 400°F. Use a medium to a large bowl to toss the squash, olive oil, salt, and pepper.
- Place the slices on the baking sheets and roast for about 10 minutes.
- Use a small to medium bowl to combine tamari, maple syrup, and ginger. Then use a kitchen brush to spread the glaze over the slices.
- Roast for about 10 minutes or until golden brown and fork-tender. Garnish with sesame seeds, serve, and enjoy!

Storage and reheating suggestions
Fridge: Airtight container, 3–4 days.
Freezer: Up to 3 months — texture softens slightly but works well blended into soups.
Reheating: Oven at 375°F for 5–8 minutes to re-crisp the glaze. Microwave works but you lose the caramelized edges.
Uncut squash: Keeps 3–4 months in a cool, dry pantry. Discard if it goes soft or moldy.
