In this post, I share my white squash mash potato recipe.  This is a fun and beautiful dish to create with a white squash you can grow in your home garden.

White Squash Mash Potatoes

The other day I was on the phone with my sister in law.  YES … I said on the phone meaning we were actually talking.  She told me about this new white squash she spotted locally at a farmers market.   You know me, I immediately had to find myself a few of these white Squash vegetables so I could make up my own mash ‘potatoes’.  I LOVE potatoes but I don’t always like the carbs ( empty carbohydrates) they come with.

About the White Squash

The flesh when baked and fluffed has the consistency of mashed potatoes and is low in sugars. The fruit set close to the crown of the plant and hold their color late into fall.  This is a hybrid so I will have to find the seeds from one of my favorite growers in order to add it to my home garden.  After trying this dish I may just grow my own in the year to come – it was super tasty with just a dab of butter.

Cooking Information

To cook the acorn squash basically pierce the washed whole squash several times.  You can microwave the white squash for about 15 minutes on about 7-8 power. Be sure to flip the squash halfway through cooking time.  If using the oven to bake it will take about 45 minutes at 350*F.  Once the white squash has cooled cut in half and remove the seeds.  Season with garlic, butter or whatever you like on your potatoes.


  • 1-2 white squash
  • butter
  • garlic salt ( I like garlic salt with parsley got from Aldi)

How to Make

  • Follow the baking directions at the top of this post.
  • Carefully remove the seeds and scoop the flesh to a mixing bowl
  • Fluff the cooked insides of the white squash for about 1-2 minutes with a hand mixer
  • Stir in butter and garlic salt.
  • Serve nice on hot!
