Sandra’s Pro Tips

Here are a few tips that you can use when you are making this easy side dish recipe to ensure that it turns out perfectly for you every time that you make it! 

  • You will need a very sharp knife to cut the outer skin because it is very hard to cut.  See my tips under the equipment list above.
  • Once the 5-minute natural release time has finished, use a quick release of the remaining steam so that your squash doesn’t overcook. 
  • Be careful when releasing the pressure after cooking — steam can burn! 
  • Once the squash has finished cooking there are so many different ways that you can serve this easy side dish. Drizzle it with maple syrup, or olive oil, and top with your favorite spices, black pepper, or even a sprinkle of brown sugar and cinnamon for a sweet taste. 
  • Wanting to scoop out the flesh for a soup recipe? A large spoon or an ice cream scoop is the easiest way to remove all the fresh.
