Calories:
- 4 tablespoons butter divided
- 4 cups russet potatoes thinly and evenly sliced
- 3 tablespoons flour
- 2 cups whole milk
- 1 teaspoon lemon zest
- 2 cloves garlic grated
- 1 teaspoon fresh thyme finely minced
- 1/2 cup onions finely chopped
- 1 teaspoon salt or to taste
- 1 cup white cheddar cheese shredded
- 1 cup smoked gouda shredded
Preheat the oven to 375° then butter a 2 quart baking dish using one tablespoon of the softened butter.
Peel and thinly slice the potatoes then set them aside then shred the cheeses and combine in a small bowl.
In a small sauce pan melt the remaining 3 tablespoons of butter then sprinkle in the flour and cook 1 minute. Whisk in the milk then add the lemon zest, grated garlic, thyme, onions and salt. Simmer 2-3 minutes or until the sauce is smooth, stirring occasionally and allowing the sauce to thicken.
Reduce the heat and stir in 1 1/2 cups of the cheeses.
Place half of the potatoes in the buttered baking dish overlapping them, then pour half of the cheese sauce over the top.
Repeat with a second layer of overlapping potatoes and the remaining cheese sauce then sprinkle the remaining grated cheese. Bake uncovered 45-60 minutes or until the potatoes are tender and lightly golden.
