1 butternut squash medium-sized, mine was 2.5 lbs. and made 2 lbs. of squash cubes
1 tbsp olive oil + 1-2 tsp. olive oil to brush pan
2 tsps fresh rosemary I used 2 tsp. but you might want less if you don't love rosemary. You can use a smaller amount of dried rosemary, but be sure it's finely chopped or ground.
