Step 2
Melt the butter in a large saucepan over medium heat. Once hot and sizzling, add the flour, then whisk constantly until it turns a golden color and smells nutty. Add the garlic and cook for 30 seconds. Slowly pour in the milk a few splashes at a time, whisking constantly to smooth any clumps. Increase the heat to medium-high, then let cook, stirring constantly, until the sauce bubbles and thickens about 8 to 10 minutes. Remove the pan from the heat, then stir in the pumpkin, cream cheese, half of the chopped sage leaves, salt, pepper, cinnamon, nutmeg, and cayenne. Continue whisking until the cream cheese melts and you have a smooth, rich sauce. Taste and add additional salt and pepper as desired.
