Roast a butternut squash at 375 degrees for 1 hour. We have a lot more about how to prepare the squash for roasting in our post.
Mince a small yellow onion. Measure out ½ cup.
Cooking Instructions
Melt the butter in a saucepan large enough to make soup. A 2½ quart saucepan is big enough. Add the minced onion and cook them down slowly on medium heat. Do not let the onions brown, but a little golden brown in the butter is perfect. (the bottom of a saucepan usually tells you how much it holds)
Add the mashed butternut squash, cinnamon, nutmeg and salt. Stir until combined.
Add the chicken broth, evaporated milk and pure maple syrup. Stir to incorporate.
Bring to a boil and then reduce the heat. Cover and simmer for 20 minutes.
For a smoother soup, use an emulsion blender, counter blender, food processor or hand mixer. This step is not necessary. It just effects the texture, not the taste.
