Thai Coconut Crab Acorn Squash Soup

This acorn squash soup is a fall-inspired adaptation of Tom Kha Gai – a Thai coconut sweet, spicy and sour soup. We’ve been ordering a local, organic bin of fruits and veggies to our door for the last year and it’s been nothing short of perfection.

Towards the end of the week we were left with a few different peppers, some bok choy and an acorn squash. I’d also bought a couple crab cakes from Seaport Merchants. I’d been trying to think of a creative way to combine squash and crab all week.

Since October has greeted us with some chilly, rainy weather, I decided to harvest most of our apartment’s back garden. While cutting down copious amounts of lemongrass, I immediately thought of the cans of coconut milk in our cupboard and everything started to come together. I had also picked the last of our carrots. Add a few aromatics and pantry items – bam! Thai Coconut Crab Acorn Squash Soup! (Are you starting to notice how much I love Thai everything?)

This soup is an amazing base for any kind of protein that you like, doesn’t need to be crab cakes! You could use shrimp, fish, chicken, tempeh, tofu or even just a variety of colourful vegetables and you’ll be bound to impress. I served this on a bed of rice, but you could do noodles or have it as a light soup.

  • 1 acorn squash, quartered + seeds removed
  • 2 cans of coconut milk
  • 2 crab cakes (can substitute fresh crab, shrimp or omit)
