Cinnamon-spiced roasted kabocha squash is a quick and delicious sheet pan side dish that’s not butternut squash, lol! Bite-sized chunks of kabocha are tossed with olive oil, cinnamon, and salt and roasted until caramelized and tender. Finished with a drizzle of rosemary maple butter, this nutrient-dense veggie side is perfect for holiday meals and easy enough for a busy weeknight.

If a pumpkin and a sweet potato had a baby, it would be kabocha squash (aka Japanese pumpkin)! It has a naturally sweet and nutty flavor, but the texture is slightly denser and drier than that of other winter squash varieties. So while everyone else is roasting up butternut squash during the fall and holiday season, I’ll be over here whipping up my cinnamon-spiced kabocha squash.

Not only is it insanely delicious (and lower in carbohydrate than most other winter squash varieties) but it’s also one of the easiest to work with. Why, you ask? Because the skin gets super soft and tender once cooked, it’s completely edible – meaning there’s no peeling required! #yourwelcome😉

Sometimes I’ll roast my kabocha squash chunks with curry powder, and my husband often requests this velvety, nourishing kabocha soup — but when I want something extra special, I go straight for this recipe! Is it the cinnamon that makes me swoon? Or is it the drizzle of rosemary maple butter right at the end? I think it’s probably both… but you’ll have to decide for yourself.

Trust me when I tell you that this simple side dish deserves a spot on your holiday table, but it’s also easy enough for a Tuesday night.

Ingredients You’ll Need

If you’re like me and you like a visual before you jump into a recipe, here it is! Most of these ingredients you probably have on hand. Just make sure ot grab fresh rosemary and your kabocha next time you pop into the grocery store.

Prepping Your Kabocha

After testing multiple ways of cutting into a kabocha squash, I have discovered the two most important steps to make this process as easy as possible.

  1. Pop the squash in the microwave for 2–3 minutes to soften the skin slightly. This will make cutting much easier because you won’t have to wrestle with a hard exterior.
  2. You must use a high-quality, sharp chef’s knife for cutting. This isn’t the time to reach for a dull, whimpy knife. You need something strong and reliable. This 7-inch chef’s knife is my go-to whenever I’m working with Kabocha. You want to use something like this, trust me!

Slice it in half from top to bottom or horizontally and scoop out the seeds with a spoon.

Then Ilike to cut it into wedges before chopping it into these fun bite-sized chunks.

Toss those playful chunks with avocado oil, cinnamon, and salt – and pop them into the oven.

This is the secret sauce my friend! Combine the butter and maple syrup in a small bowl and microwave for 20–30 seconds, or until melted. Stir in the freshly chopped rosemary and then right before serving…

Drizzle the maple butter over the top and finish with a generous pinch of flaky sea salt (Maldon is my go-to choice for flaky sea salt). Holy cow!! Sit back and swoon because it’s just SO good.

Ways to Serve Your Squash

This winter squash is a beautiful side dish on any holiday table! But when I’m looking for a quick, no-brainer healthy dinner for my family, I pair it with cast-iron chicken thighs. It’s the perfect cozy combo.

If I’m lucky enough to have leftovers, I eat them for breakfast right alongside scrambled eggs with hidden cauliflower rice. Kabocha and eggs are the perfect combo, and this veggie, fiber, and protein-packed breakfast is to-die-for.

Thanks so much for reading! If you make this recipe, I would love you to give it a ★ rating below. Follow me on YouTube, Instagram, and Facebook for more healthy food inspiration. Cheers!

Author: Dani Spies
Prep Time10 minutes mins
Cook Time25 minutes mins
Servings: 6 servings
Calories: 129kcal

Ingredients

  • 3-3.5 pound Kabocha squash seeded and cut into 1-inch cubes (about 8-10 cups chopped)
  • 1 tablespoon avocado oil
  • 1 heaping teaspoon cinnamon
  • 1/2 teaspoon sea salt plus more for finishing
  • 2 tablespoons butter
  • 2 tablespoons maple syrup
  • 2 teaspoons fresh chopped rosemary

Instructions

  • Preheat your oven to 425°F and adjust the rack to the center position. On a rimmed baking sheet, toss the squash with olive oil, cinnamon, and salt until evenly coated. Spread the squash out in a single layer, leaving a little space between each piece—this helps them brown and roast evenly on all sides.

  • Roast for 25 minutes (no need to flip!) or until the bottoms are golden brown and the squash is fork tender.

  • While the squash is cooling, add the butter and maple syrup into a small bowl and pop into the microwave for 20-30 seconds or until melted. Stir in the fresh chopped rosemary.

  • Transfer the roasted squash to a serving dish and drizzle with maple butter. Top with a fat pinch of sea salt and enjoy!

Notes

Storing Leftovers
  • To store leftovers: Let the squash cool completely, then transfer it to an airtight container and refrigerate for up to 4 days. Reheat in the oven or air fryer to bring back some of that roasted texture.
