- 1 tablespoon unsalted butter
- 1 small onion, peeled and diced
- 4-3/4 pounds pumpkin, peeled, seeds removed and diced
- 1 small potato, peeled and diced
- 5 cups water
- Sea Salt
- 3/4 cup Gruyère or Comté cheese, grated
- Melt the butter in a large heavy saucepan over medium-high heat. Add the onion and cook, stirring, until it begins to turn translucent, about 5 minutes.
- Add the pumpkin, the potato, and the water; stir, and then season lightly with salt. Cover and bring to a boil. Reduce the heat to medium and cook, covered, until the pumpkin is so soft that it comes apart, 25 minutes. Remove from the heat and purée the mixture in a food processor or with a wand mixer until smooth and uniformly blended.
- Taste for seasoning, and serve with the cheese alongside.
