4 lb.

Russet potatoes (about 4 large potatoes), peeled

Nonstick cooking spray

Step  1 In a large skillet, heat 2 tablespoons of the butter over medium heat.


Add the onion and cook, stirring occasionally, until softened, 4 to 6 minutes. Add the garlic and cook, stirring occasionally, until fragrant, about 1 minute. Step  2 Add the remaining 3 tablespoons of the butter to the skillet over medium low heat. Add the flour and cook, stirring constantly, until smooth and very lightly browned, about 1 minute. Gradually whisk in the cream until smooth and well combined. Whisk in the salt, thyme, and pepper. Bring the mixture to a simmer, whisking constantly, over medium heat.
