Instant Pot Acorn Squash recipe

I love Acorn Squash, and my family does, too.  It’s so sweet and tender cooked in the Instant Pot.  And, it has fewer calories than Butternut Squash or potatoes, and even more fiber, making it more like a vegetable than other winter squashes.   In this recipe, I suggest adding some additional sweetness with maple syrup and cinnamon, which my kids love.   Makes it really tasty, and they get all that vegetable goodness, too!

A full cup of acorn squash contains only about 115 calories, 40% of the RDA of Vitamin C,  26% of the RDA of potassium and 22% RDA of magnesium.  And almost 40% of your RDA of fiber!  Fiber helps to regulate blood sugar eliminate excess cholesterol in the body    Acorn squash also has significant levels of Vitamin A (good for your eyes and skin), and thiamin, pantothenic acid, and other B vitamins.  And it provides lots of good-for-you minerals, too:  potassium, magnesium, manganese, iron, copper, phosphorus, and calcium.    And last but not least, it also has loads of anti-oxidants!   I love that this Instant Pot Acorn Squash is so easy, so yummy, and so healthy!   And of course, its gluten-free, and paleo and whole30 friendly!

Pressure Cooker Acorn Squash

Tips:  Vegans, use a little coconut oil!    Serve with a spoon to eat – you’ll get all the succulent flesh without tearing through the skin.  Or, scoop the flesh out after cooking, and mash up with the butter and whatever seasonings or spices you want.   Maple Syrup and cinnamon are a favorite in my house, and if you have a little bacon left over from breakfast (cook an extra slice or 2), crumble or chop that up as a garnish – talk about sweet and savory goodness!

No maple syrup?  Add a sprinkle of brown sugar.    You can also add a splash of orange juice for something a little different. Or sprinkle with chili powder for a spicy version!

  1. THANK YOU! Perfect to cooking whole. Way too much work to cut. I scoop (AND SAVE) the seeds and throw the flesh (so easy to get rid of the paper-thin skin) into a large bowl with farro, onions, and garlic and that will be a very nice little meal. Roast the seeds (marinated with avocado oil and seasonings) in 400 degree oven until clearly crunchy. Soooo good!

  2. 5 stars
    The video made it so easy to follow. Thank you! The instructions are also very clear. The acorn squash after 15 min in High Pressure had a perfect consistency. I’m bookmarking this recipe. I’m planning to add it as part of on my regular meal prep.
