Creamy Kabocha Squash Mash
Meet your new favorite fall and winter side dish! Kabocha Mash is creamy, cozy, and naturally sweet. This simple recipe transforms roasted kabocha squash into a velvety mash infused with rosemary, warm cinnamon, a touch of maple syrup, and bright orange zest. It’s an effortless way to elevate any weeknight dinner—and it’s special enough for the holiday table!
I’ve been a huge fan of kabocha squash since the first time I tried it in cooking school. It is a Japanese pumpkin with a dark green rind that’s completely edible, and it has a sweet, nutty flavor and rich, starchy texture.
Its special flavor and texture is what prompted me to try roasting it and mashing it, and the recipe for this Creamy Kabocha Squash Mash was born.
The kabocha squash is roasted in the oven until tender, then the flesh is scooped into a bowl and mashed with softened butter, half and half, orange zest, a bit of maple syrup and freshly chopped rosemary.
The flavors are slightly reminiscent of my sweet potato casserole with streusel, but with a lot less sweetener and ingredients.
This is a delicious change of pace from my family’s favorite yukon gold mashed potatoes, and I promise nobody will miss the potatoes! 🙂

How to cut and roast kabocha squash
I’ve included some tips on how to cut kabocha squash in my produce guide and collection of kabocha squash recipes, but below is an in-depth tutorial on the different methods to cut and roast it for this recipe.
Method 1: Microwave First (Safest & Easiest for Slicing)
Microwaving the kabocha for a few minutes before cutting it minimizes the risk of slipping while cutting. There’s no struggling with the hard rind, and it shortens roasting time a bit.
If you’re comfortable cutting through the hard rind, simply skip the first step below.
Method 2: Roast the Squash Whole (Zero Knife Work Upfront)
This is the safest and most hands-off method. No knife is needed until the squash is soft after roasting, and it’s the easiest way to remove seeds.
- Place the whole squash on a foil lined baking sheet.
- Roast 45–60 minutes at 400 degrees, depending on size, until the tip of knife is inserted very easily.
- Allow the kabocha to cool until it’s comfortable enough to handle.
- Slice it open, scoop out the seeds, then scoop out the flesh with a large spoon.
How to make kabocha mash
Mashed kabocha squash is very easy to make, especially once the squash has been roasted using one of the methods above.
Pro tip: Roast kabocha 1-2 days in advance to make prep go faster on busy nights. Simply reheat before adding the other ingredients.
