Ingredients

1 ounce (2 tablespoons) unsalted butter

1 medium onion, finely chopped (1 cup)

2 small garlic cloves, minced (2 teaspoons)

Coarse salt and freshly ground pepper

2 stems fresh rosemary

4 fresh sage leaves

2 pounds buttercup, butternut, Hubbard, or kabocha squash, peeled, seeded, and cut into 2-inch cubes

1 pound Yukon Gold potatoes (about 2 medium), peeled and cut into 2-inch cubes

3 cups homemade or store-bought low-sodium chicken stock, plus more if needed

2 cups water, plus more if needed

Herbed Crostini

Preparation

Melt butter in a medium stockpot over medium heat. Add onion, garlic, and 1 teaspoon salt. Cook, stirring occasionally, until onion is translucent, about 5 minutes.

Place rosemary and sage on a small square of cheesecloth, and tie with kitchen string. Stir in the herb sachet, squash, potatoes, stock, and water. Bring to a boil, then reduce heat to a simmer, and cook until vegetables are soft, about 15 minutes. Discard herb sachet. Let cool slightly.

Working in batches, puree soup in a blender until smooth. Adjust to desired consistency with stock or water. Season with salt and pepper. Serve with crostini.
