Butternut Squash Soup

Yes, prepare through step 9 (before adding spices) and refrigerate up to 3 days, or freeze up to 2 months. Thaw overnight in the refrigerator, reheat gently over medium-low heat on the stovetop, then stir in the spices and cream at the end.

Kabocha squash, acorn squash, or sugar pumpkin work well—use the same weight (about 3 pounds). Roast exactly the same way. Avoid pre-cut squash from the grocery store, which dries out quickly; buy whole if possible.

Under-roasting the squash, so the flesh is still watery and pale, resulting in thin, bland soup. Roast until the flesh is completely tender and the edges begin to caramelize (40–45 minutes). Properly roasted squash has concentrated, slightly sweet flavor.

Canned pumpkin (which is actually squash puree) works in a pinch: use 1.5 cups canned puree instead of roasted squash, whisking it into the stock. Reduce stock to 3.5 cups. It's more convenient but less flavorful than roasted fresh squash.

Roast the squash in the oven as directed (this step cannot be rushed), then blend it with stock and cream on the stovetop. Do not try to cook raw squash in a pressure cooker or slow cooker; the flavor will be watery. Roasting is essential.

Refrigerate in an airtight container up to 3 days. Reheat gently over medium-low heat on the stovetop, stirring occasionally and adding a splash of stock or cream if it has thickened. Do not microwave, as it can scorch; gentle stovetop reheating preserves the silky texture.
