What Is Kabocha Squash?

Kabocha squash is a Japanese winter squash with a deep green exterior and bright orange flesh. It’s naturally sweet and has a dense, starchy texture that makes it especially delicious when roasted.

When cooked, kabocha becomes tender and creamy on the inside while the edges can become lightly caramelized and crisp.

If you’ve never tried kabocha before, this is a great recipe to start with. The cinnamon or pumpkin pie spice highlights the squash’s natural sweetness and makes it especially delicious during the fall and winter months.

Liquid Egg Whites

Liquid egg whites are the secret ingredient that makes this recipe high in protein without adding oil. They coat the squash and help the spices stick while adding protein to every serving.

Cinnamon Or Pumpkin Pie Spice

Use cinnamon for a simple, naturally sweet flavor or pumpkin pie spice if you want even more fall flavor.

How To Make Oil-Free Roasted Kabocha Squash

Start by cutting your kabocha squash into bite-sized pieces.

Add the squash to a bowl along with the liquid egg whites and cinnamon or pumpkin pie spice. Toss everything together until the squash is evenly coated.

Line your air fryer basket with parchment paper and add the coated squash in an even layer.

Air fry at 400°F for 14 minutes.

Carefully toss the squash, then return it to the air fryer for another 6 minutes, or until the squash is tender and lightly browned.

That’s it! Your high-protein roasted kabocha squash is ready to enjoy.

Tips For The Best Air Fryer Kabocha Squash

Cut the squash into similar-sized pieces. This helps everything cook evenly and prevents smaller pieces from becoming overcooked while larger pieces are still firm.

Don’t overcrowd the air fryer. Spread the squash into as even a layer as possible for better browning. This is the air fryer I use!!

Use parchment paper. Since we’re not using oil, parchment helps prevent the egg-white coating from sticking to the air fryer basket.

Adjust the spices to your taste. Cinnamon gives the squash a simple sweet flavor, while pumpkin pie spice makes it taste even more like fall.

Toss halfway through cooking. This helps the squash cook and brown more evenly.

How To Serve Roasted Kabocha Squash

This easy roasted kabocha squash is incredibly versatile. Enjoy it as a healthy side dish alongside your favorite protein, add it to a fall-inspired grain bowl, or eat it straight from the air fryer as a protein-packed snack.

You can also pair it with Greek yogurt or your favorite high-protein dip for an extra boost of protein.

For a sweeter option, add a sprinkle of cinnamon after cooking and serve it warm.

How To Store Leftover Kabocha Squash

Store leftover roasted kabocha squash in an airtight container in the refrigerator for up to 3 to 4 days.

To reheat, place the squash back in the air fryer at 350°F for a few minutes until warmed through. This helps bring back some of the roasted texture.
