Butternut Squash Puree

Why This Butternut Squash Puree Works

In the hot oven, the squash slowly softens all the way through. Sitting cut side down traps a bit of steam between the squash and the pan, so the inside cooks gently instead of drying out. The olive oil on the cut surface keeps the flesh from sticking and lets the edges brown a little, which makes the squash taste sweeter as it cooks. By the time a fork slides in easily, the tough raw texture is gone and the inside is very soft and mashable.

After roasting, the squash rests for a bit, which lets some steam escape so the puree doesn’t end up watery. Once the soft flesh goes into the blender with a small amount of water, the already-tender pieces break down quickly into a smooth puree. Adjusting the water at the end controls how thick or thin it is, so the final texture stays silky and easy for a baby to eat.

Mistakes To Avoid

Pulling the squash from the oven too early leaves the flesh firm and stringy, so it doesn’t blend smoothly. The blender then has to work harder, and the puree ends up with little lumps and fibers instead of a soft, even texture for a baby.

Letting the squash roast way past tender can dry it out and darken the edges. Once blended, this over-roasted squash turns into a thicker, pastier puree that can taste slightly bitter and needs a lot more water to loosen, which can make the texture uneven.

Cutting the squash into uneven halves or leaving one side much thicker than the other causes one half to cook faster. The thinner side can start to dry and brown while the thicker side stays a bit hard, so the final puree swings between mushy and slightly chunky.

Blending the squash while it is still very hot traps steam in the blender. This can thin the puree too much at first and also creates a looser texture that thickens oddly as it cools, making it harder to judge the right consistency.
