How to Cut, Peel and Cube Butternut Squash

Steps showing how to cut butternut squash.

  1. Start by using a quality chefs knife and a sturdy cutting board. Carefully cut off both ends of the squash. Note: Make sure to use a sharp knife when cutting butternut squash. Taking a few minutes to sharpen it before starting will save a world of hassle. 
  2. Cut the squash in half at the point where it curves. 
  3. Using a comfortable vegetable peeler, peel off the skin.
  4. Cut each half in half again.
  5. With a spoon remove the seeds and the stringy inner core.
  6. Cut sections into strips by placing them facing down and then cutting.
  7. Cut the strips into 3/4- 1-inch cubes. 


Ingredients Needed

Ingredients for Roasted Butternut Squash laid on a white countertop.

  • Butternut Squash– Choose a butternut squash that is medium to medium-large in size. Here is a helpful guide to pick the best butternut squash.
  • Olive Oil– A good quality olive oil makes a huge difference in achieving delicious results. Look for olive oil that have an estate or mill name on the bottle along with a harvest date. This is because real olive oil has a short life span.
  • Salt– I originally started using this gourmet salt because of its low iodine levels. However, I fell in love with the flavor and now use it as both a finishing salt and for cooking. 
  • Smoked Paprika– Adds sweet and smokey undertones to the butternut squash. 
  • Black Pepper
  • Garlic Powder– Unfortunately, fresh garlic when heated sometimes turns either blue or green. It is still fine to eat when it does turn colors but is can be unappealing. The easiest solution to prevent this is to use garlic powder. 
  • Rosemary– The distinctive earthy flavor of rosemary works incredibly well with  with vegetables like butternut squash and also soup, crackers,  beef and chicken.

Variations For This Roasted Butternut Squash Recipe

The secret to incredible recipes is to personalize them to your taste preferences. Changing up herbs and spices is one of the easiest ways to do this. Here are a few ideas to personalize this Roasted Butternut Squash for your dinner table. 

Spicy Roasted Butternut Squash

Instead of using smoked paprika try using 1/2-1 teaspoon of either chipotle powder, cayenne pepper or real chili powder. Additionally, cumin would be a tasty replacement for the rosemary when raising the heat. 

Sweet Roasted Butternut Squash

Replace the smoked paprika with cinnamon and add in a few tablespoons of maple syrup or brown sugar for a sweet alternative.

More Herb Options 

Ground sage, rosemary (dried and ground rather than fresh) and dried or fresh thyme, marjoram and oregano would all be delicious with butternut squash. Additionally, it is important to use less of the dried ground herbs since they are much more potent than fresh. Because of this, use no more than 3 teaspoons of dried in total. You can use either a single herb or combination of herbs.
