Thai Acorn Squash Soup is a great vegetarian soup for fall, made with acorn squash, coconut milk, lime juice and red curry paste.
There are tons of recipe out there making a Thai flavored soup using butternut squash, but my fall CSA box came with two acorn squashes. As I love Thai flavors, I figured it was worth a shot to use acorn squash instead and I am SO GLAD I did. Not only is this squash recipe healthy, it's delicious!
What is an acorn squash?
An acorn squash is a green, winter squash that kind of looks like an enormous acorn. Creative name, right? Acorn squash can be served savory or sweet. Most savory recipes call for stuffing the squash with ingredients like sausage, rice and veggies and then roasting it in the oven. Sweet recipes will coat in it brown sugar or maple syrup and cinnamon, then roast it.
Like most varieties of squash, acorn squash has a mild flavor and requires other ingredients to really make it shine.

FAQ's about acorn squash
- Is acorn squash healthy? It is full of fiber and potassium so it's pretty healthy
- How do I know if acorn squash is ripe? The squash will remain green, usually with one large orange spot. If it is more orange than green, it's very ripe. As long as there is no mold or rot, it is still safe to eat.
- Can I microwave acorn squash? Absolutely! Winter squashes are really hard to cut through, so pierce it with a fork a few times and microwave for a minute or two to soften that harder outer skin, making it easier to slice.
- How long does acorn squash last? Unlike other winter squashes that can hang out in your kitchen for weeks and weeks, an acorn squash is best eaten within 2 weeks.
