- Heat butternut, chicken broth, and milk in a saucepan until steaming hot, but not boiling
- Transfer to a blender, and blend until completely smooth
- Add remaining ingredients and blend until smooth
- Serve hot as you would any other cheese sauce
Note: You can also do the entire thing in a sauce pan using an immersion blender. Just add the cheese after blending your butternut and milk, and stir until smooth rather than blending again.
