Pumpkin is an incredibly versatile fruit—yes, it’s technically a fruit. It can be transformed in numerous ways, such as into:
- pumpkin puree,
- flavourful savory pumpkin soups,
- pumpkin spice lattes,
- pumpkin muffins,
- pumpkin pies,
- pumpkin cake,
- pumpkin cheesecakes.

Is Pumpkin a Fruit or a Vegetable?
From a botanist’s point of view, a pumpkin is a fruit because it comes from the seed-bearing structure of flowering plants. Vegetables are the edible parts of plants like leaves, stems, roots, bulbs, flowers, and tubers. However, since pumpkins are less sweet and more savory, they’re often categorized as a vegetable in the culinary world.

Back To Our Keto Pumpkin Dessert
Growing up, my grandparents cultivated their own pumpkins, along with other fruits and vegetables. I was quite spoiled, always having access to homegrown, organic pumpkins.
And naturally, this led to an abundance of pumpkin-flavored desserts.
Roasted pumpkin was the staple dessert. It’s simple to prepare and can be flavored to your liking.
In this keto pumpkin dessert recipe, I’m excited to share my personal favorite flavor.
Watch me make this recipe in my quick video – it’s like cooking together in the kitchen!
Tips for Choosing Pumpkin for Keto Roasted Pumpkin
Different pumpkin varieties yield varying purée textures and flavors. While any pumpkin can be used for purée, the results will differ.
Consider trying different types of winter squash:
- Butternut squash, with its orange flesh, dense texture, and sweet taste,
- Kabocha (Japanese squash), which has yellow flesh, an earthier flavor, and becomes fudgy when cooked.
- The common orange pumpkins seen at Halloween often lack flavor and can be watery.
- The orange pumpkins, which we see everywhere at Halloween, usually don’t have much flavor and can have watery flesh.

Ingredients
- Pumpkin
- Sweetener
- Cinnamon
How to Make Keto Roast Pumpkin
How to cook fresh pumpkin?
This dish is incredibly easy to make.
Start by washing your pumpkin and removing any packaging or labels.
Then, slice the pumpkin into your preferred shape. I tend to cut mine into hearty chunks.
Now for the fun part – flavoring!
Season your roasted pumpkin dessert to taste. I highly recommend trying a simple blend of cinnamon and sweetener—it’s delicious and fills your kitchen with a wonderful aroma!
Alternatively, you can flavor your low-carb pumpkin dessert with just sweetener. I prefer granulated Stevia, which melts over the pumpkin, creating a delightful taste.
Another option for flavoring your pumpkin dessert is to use pumpkin spice.
There are plenty of ideas for a pumpkin dessert. However, you might also opt to make a savory snack—stay tuned for that post.
Preheat your oven to 400°F (200°C). Arrange the pumpkin slices on an oven-proof tray and roast for 20 to 30 minutes. Adjust the time based on the size of your slices.
And that’s it! Enjoy your keto-friendly treat!

Substitution Suggestions
If you’re out of cinnamon, warm spices like nutmeg or allspice will do the trick.
Feel free to use any sweetener that suits your taste or dietary needs, whether it’s Stevia or Swerve, the choice is yours to make this dessert as sweet as you like!
Serving Suggestions
Serve this delicious roasted pumpkin dessert straight from the baking pan with a dollop of cool whip or cream cheese frosting for an easy dessert that’s sure to impress.
If you’re feeling fancy, a drizzle of sugar free maple syrup or sugar free honey. And don’t forget, a pumpkin spice latte is the best way to wash down this comforting recipe—it’s a great idea for any time of year, especially during those cozy autumn months.
Storage Tips
Keep your pumpkin treats fresh! Store any leftovers in an airtight container in the refrigerator for up to three days.
For longer storage, freeze individual servings wrapped in cling film. When you’re ready for more, let it thaw at room temperature or give it a quick warm-up in the oven. It’s the easiest way to enjoy your delicious treat the next time you crave it.
