Ingredients

• 2 pounds russet potatoes, peeled and cut into 1-inch cubes

• 1/2 cup low-fat milk
• 2 tablespoons all-purpose flour

Bring a large pot of salted water to a boil. Add the potatoes and cook until just tender, about 8 minutes. Drain and set aside.

In a medium saucepan, melt the butter over medium heat. Add the milk and whisk to combine. Add the flour, garlic powder, onion powder, salt, and pepper and whisk until thickened.
