FAQ’s re: Instant Pot Mashed Butternut Squash

What’s the best way to soften butternut squash?

Our go-to before this recipe was always oven roasting to get really good flavour, but that heats up and ties up your whole oven for a long time.

Microwaving is also an option but can produce uneven cooking if you don’t keep rotating the squash. Using the Instant Pot gets it done fast and cooked evenly.

Can you overcook butternut squash?

It depends on what texture you are aiming for.

If you want the squash to keep its shape, like with small chunks in a Thai curry, you can have it cooked in as little as 10-15 minutes depending on the size. Cook it beyond that and it goes mushy and you lose the texture you were aiming for.

However, in most other uses (mashed, like this recipe or for soup), cooking squash longer makes it soft and easy to eat. If you’re using this Instant Pot Mashed Butternut Squash recipe, you should be able to avoid overcooking because the Instant Pot does all the timing!

Is it necessary to peel butternut squash before cooking?

Again, depending on the use, it might be. Most recipes that require the squash to keep its chunk shape, like this sheet pan recipe, would need peeling ahead of time.

When oven roasting, microwaving or cooking in the Instant Pot, you can leave the skin on and remove the flesh from it after it is cooked and softened!
