Ingredients

3 pounds Yukon Gold potatoes
4 tablespoons butter unsalted
4 cloves garlic minced
½ medium yellow onion diced
3 tablespoons all-purpose flour
2 cups whole milk room temperature
½ teaspoon ground mustard
¼ teaspoon cayenne pepper
1 teaspoon salt
½ teaspoon black pepper
1 ½ cups Cheddar cheese shredded
1 cup Parmesan cheese shredded

Instructions

Preheat the oven to 375º Fahreneheit and grease a 9x13” baking dish.
Peel the potatoes and cut them into thin (about ⅛” thick), uniform slices.
Melt the butter over medium-high heat in a medium-large saucepan. Add the garlic and onion and sauté until the onions are translucent - about 3 minutes.
Add the flour and continuously stir for about 3 minutes or until the mixture is bubbly. Gradually add the milk. Stir continuously and add the ground mustard, cayenne pepper, salt, and pepper.
Let the sauce simmer for about 5 minutes or until it starts to thicken. Once it has thickened, remove it from heat.
Layer half of the sliced potatoes in the bottom of the prepared 9x13” baking dish.
Pour half of the sauce over the potatoes and gently spread it into an even layer. Sprinkle half of the Cheddar cheese and half of the Parmesan cheese over the sauce.
Layer the rest of the potatoes over the cheese then top with the remaining sauce and cheeses.
Cover the baking dish with foil and bake for 35 minutes. Remove the foil and bake for another 25-30 minutes or until the potatoes are tender and the top starts to brown.
Let the dish rest for about 15 minutes before serving.
Optional: Garnish with freshly chopped parsley just before serving.

Notes

If prepping ahead of time, you can keep the potatoes from turning brown by slicing and then adding to a bowl of cold water.

You can also add a splash of lemon juice or vinegar to keep them fresh even longer if you want to slice the potatoes the night before. Cover the bowl tightly and keep it in the fridge until you're ready to use.
