Ingredients to make Mashed Butternut Squash

  • Butternut squash — Make sure to use a ripe squash. The butternut squash will turn a light tan colour when it’s ripe, and once roasted, it becomes tender, soft, and buttery.
  • Olive oil — or an oil of your choice.
  • Garlic Cloves — Freshly minced garlic is perfect for this roasted butternut squash mash.
  • Ghee or butter — ghee will keep this mash whole30-friendly. Be sure to use unsalted butter.
  • Salt and black pepper
  • Cayenne pepper — a pinch for garnishing the top of the mash.
  • Optional – if you can eat dairy, you can add parmesan cheese and even 1 tablespoon of heavy cream for more flavor. 
  • You can also garnish your mashed butternut with rosemary or sage leaves.

Instructions to make Mashed Butternut Squash

This is one of the easiest ways to make butternut squash mash. You just need to follow the few steps below to have a yummy and smooth mash to serve at dinnertime.

  • First, preheat the oven to 400ºF. Prepare the baking sheet by lining it with parchment paper or aluminum foil. Wash the butternut squash and cut it in half lengthwise.
  • Then, using a spoon, scoop out the seeds.
  • Place both halves face up on the prepared baking sheet. Drizzle with olive oil. Pour as much olive oil on as you want. It will add lots of flavour to this dish. Then, season with salt, pepper, and garlic.

  • Roast in the oven for 45-60 minutes until fork tender. The time depends on the size of the butternut squash. Remove the squash from the oven, and let it cool for about 5 minutes. Using a large spoon, remove all the squash flesh from the skin.

  • Place the squash flesh into a large mixing bowl for mashing. Add the ghee, sea salt, and pepper, and mash them well with a potato masher, food processor, or hand blender until fluffy and smooth. Sprinkle with some cayenne pepper and add ghee for extra flavour before serving.

Recipe tips

  • While you can boil or steam the squash before mashing, roasting is my go-to method as it takes less work. No need to peel and dice the squash when you’re roasting it! You also risk the mash being watery if you boil the squash as it’ll retain water whereas when roasted, excessive moisture leaves the squash.
  • If you’re having difficulty cutting the butternut squash, prick the squash all over with a fork. Then, microwave the squash for about 3 minutes. Doing so will soften the skin and make it easier to cut the squash in half.
  • Be generous with the salt and pepper on the squash before roasting. This way the squash is more flavourful.
  • For some sweetness, sprinkle some brown sugar over the butternut squash before roasting it. This gives the roasted butternut squash a caramelized layer that adds a layer of sweetness to the mash.
  • Cinnamon and nutmeg make for a great addition to the mash.
  • Season with more salt and pepper if needed.

What’s the best way to mash butternut squash?

You can use either using a hand masher, food processor, or an electric hand or stand mixer. Similar to mashed potatoes, using a mixer will give you a creamy smooth consistency.

If you don’t have any of these in your kitchen, mashing the squash with a fork is will work as well. It’ll just take longer.

Can I make this ahead of time?

Yes, you can make this butternut squash mash ahead of time! Just leave off the cayenne pepper and place the mash in an airtight container in the fridge for up to 4 days.

I recommend reheating in short bursts in the microwave or in a pot on the stove. Alternatively, you can cut the squash in half and store it in the fridge for up to 1 day in advance.
