To make butternut squash baby food, cut a whole butternut squash in half and scoop out the seeds. Bake the butternut squash halves in the oven until they're tender, and then scoop out the flesh from the skin. Place the softened squash in a blender or food processor, and blend until it is completely smooth, adding a small amount of water if necessary.
- Wash the butternut squash
Rinse the butternut squash under cold running water. Use a vegetable scrubber if necessary to remove any dirt.
- Remove the seeds
Slice the butternut squash in half lengthwise using a sharp chef's knife. Scoop out the seeds with a spoon.
- Bake the squash
Brush the cut sides of the butternut squash halves with olive oil, then place them cut-side down on a baking sheet. Bake them in the oven at 400 degrees Fahrenheit for 30 to 45 minutes, until the squash is tender. Remove the squash halves from the oven, and allow them to cool.
- Puree the squash
Scoop out the butternut squash flesh, leaving only the skin, and place it in a blender or food processor. Blend or process the butternut squash until it reaches a smooth, pureed consistency. Add about a tablespoon of water for a thinner consistency.
