Once you know the type of fresh pumpkin to use, it is as easy as roasting then making your own puree.

This time of year you can find a sugar pie pumpkin just about everywhere from the grocery store to farmer’s markets.

Stock up during the autumn season and then use your own homemade puree for pumpkin pie filling and other seasonal goodies.

What Pumpkin Should I Use for Baking?

Leave the large carving pumpkins for jack o lanterns and choose a small sugar pumpkin (also called a pie pumpkin) that is about 2-3 pounds in weight.

These smaller pumpkins are specifically grown for baking. They are less fibrous than big pumpkins and also are more flavorful. Sweet pumpkins can be found in the produce section during fall, often near other winter squashes.

After roasting whole pumpkin, soft flesh can be pureed to use in your favorite recipes, anything from pumpkin pie to healthy pumpkin pie bars and even pumpkin spice chia pudding.

How to Cook a Whole Pumpkin

My preferred method if I am planning to puree it later, is to bake the pumpkin whole without cutting it first. As a bonus, you also don’t have to cut through the hard outer shell!

This allows the inside to steam vs. caramelize and the bright orange flesh is easy to make into your own homemade pumpkin purée.

Let me show you how to bake a pumpkin whole. It’s such an easy recipe!

Person showing step by step how to roast whole pumpkin in the oven.
  1. Preheat oven to 400 degrees F and line a large baking sheet pan with parchment paper.
  2. Wash and dry your pumpkin. Using a sharp knife, pierce entire pumpkin about 10 times to allow steam to escape.
  3. Place on a baking sheet and cook for 60 minutes. The actual cook time will depend on the size of squash and your oven. Your pumpkin is ready when it’s skin is darker and can be easily pierced with a fork.
  4. Remove it from the oven, place on a cutting board and let cool for 20 minutes. Then wearing oven mitts cut pumpkin in half then proceed to scrape out seeds and stringy bits with a large spoon.

Recipe Tip

Save your seeds for making pumpkin seeds in the air fryer!

How to Cut a Pumpkin for Cooking?

To cut a pumpkin there are two popular methods. You can cut crosswise or lengthwise, very similar to how to cut spaghetti squash in half.

  1. Cut crosswise: Cutting through the middle of raw pumpkin will leave one half with stem and other without stem.
  2. Cut lengthwise: Make a cut right next to the stem, as close to the center of the pumpkin as possible. One half your pumpkin may be slightly larger, but should still bake evenly.

How to Bake Pumpkin Halves

There are two benefits of cutting your pumpkin first before cooking. The two halves will cool faster and the raw seeds are easier to clean for roasting later.

  1. Cut the pumpkin, remove seeds and other fibrous strings. Save seeds for other use, for example try to air fry pumpkin seeds.
  2. Brush the inside and edges of the pumpkin with olive oil, then arrange them on a large baking sheet, with halves cut-side-down. To save on clean up time, line the pan with parchment paper.
  3. Roast at 350 degrees F for 45 minutes or until fork tender. This is based on the average 2-3 pound sugar pumpkin, yours may take longer if it is larger in size.
  4. Cool, then proceed to scoop out the flesh and make your own pumpkin puree.

How Long to Roast a Pumpkin?

How long to bake a pumpkin will depend if you are cooking a whole pumpkin or roasting pumpkin halves.

To bake whole pumpkin will take 60 minutes. Roasted sugar pumpkin halves will take around 45 minutes. The size of your pumpkin as well as your oven could increase the time it takes to bake.

Your pumpkin is done when you can easily pierce the skin with a knife.

How to Make Homemade Pumpkin Puree

Transforming your baked whole pumpkin or pumpkin halves into puree is so simple and it tastes so much more fresh than canned pumpkin puree! Just follow the easy steps listed here.

  2. Then scoop out soft pumpkin flesh and add it to a blender or food processor.
  3. Process into a smooth puree, stopping and scraping the sides as needed, about 2-3 minutes.

Afterwards, you could also freeze it in portions in freezer bags to be used in your favorite pumpkin recipes year round.

How to know when the pumpkin is done roasting?

You should be able to pierce the skin easily with a knife. Sometimes though, you may have a pumpkin with an incredibly thick skin. If it’s been over an hour, odds are that it’s roasted enough to proceed with the recipe.
