To cut: First wash and dry the squash. Using a sharp knife, cut ends off. Peel the skin using a vegetable peeler. Cut in half and scoop out the seeds. Then cut the flesh into half moon shapes.
Place water in a pot, add steamer basket, and bring to a boil. Add the squash, cover, reduce heat to medium, and cook for 15-20 minutes, until fork tender.
Let it sit covered for 5 minutes to continue steaming. Cut into desired size.
Roasted
To cut: First wash and dry the squash. Place on a study cutting board (recommend placing a kitchen towel underneath) and trim the stem and bottom of the squash. Carefully cut in half lengthwise. Remove the seeds using a spoon.
Preheat oven to 400°F. Line a large baking sheet with parchment paper or baking mat.
Brush both halves with oil and seasoning(s) of choice. Place the squash cut side down on the baking sheet. Roast until the flesh is soft and fork-tender, about 30-45 minutes, for 1 ½ to 2 pound squash.
Turn the squash over and allow to cool. Cut according to your baby's age. The skin should easily peel back.
