Learn how to cook pumpkin for pie using your Instant Pot! This easy method turns a whole pie pumpkin into silky, fresh purée in under 15 minutes—no oven required. Perfect for pumpkin pie, cookies, cheesecake, lattes, breads, and more. Yields 3–4 cups.
Rinse the pumpkin and pat dry. Slice off the stem end. Stand upright and cut in half from top to bottom.
Scoop out seeds and strings with a spoon (the strings more easily come off once the pumpkin is cooked). Save seeds for roasting if desired.
Cut each half in half again for easier fitting.
Pour 1 cup water into the Instant Pot. Insert the trivet.
Arrange pumpkin pieces skin-side down on the trivet.
Secure lid, set valve to SEALING. Cook on HIGH pressure for 6 minutes.
Natural release for 10 minutes, then quick release remaining pressure.
Let cool 5 minutes. Peel off skins—they should slide off easily.
Before discarding the skins, lightly scrape the inner surface of each cooked piece with a spoon. That thin, bright-orange layer is pure gold—it instantly gives you deeper color and a noticeably thicker, more flavorful purée. Takes 10 seconds and makes a huge difference!
Transfer flesh to a bowl. Blend with immersion blender or food processor until smooth.
(Optional) Press through a fine-mesh sieve for ultra-smooth texture.
Notes
Pumpkin Varieties: Only use pie pumpkins (small, sweet) or buttercup squash, not jack-o'-lantern varieties.
Don't Peel: No need to peel before cooking—skins remove effortlessly after pressure cooking.
Thicker puree: Drain excess liquid or simmer on Sauté mode.
Pumpkin Amount for Pie: 1 standard 9-inch pumpkin pie uses 1¾ cups purée.
Scrape for better purée: After removing the skin, gently scrape the inside of each cooked chunk. This captures the most vibrant, flavorful layer and results in richer color + thicker texture with zero extra effort.
