Instructions
Grease a 9 x 13 inch dish with butter, and set aside. Preheat the oven to 350F.
Melt the butter in a large heavy-bottom saucepan. Add the flour, and stir well, until it's completely incorporated and smooth.
Add 3 cups half and half, and whisk until smooth. Add the garlic salt and a dash of Tabasco Sauce, and stir well. Add another cup of half and half if you want a thinner sauce as well as any optional add-ins (see notes). Bring sauce to a boil and turn heat to low, stirring constantly for about 1 minute.
Stir in the shredded cheeses, reserving about ¼ cup of each to sprinkle on top of the dish.
Place about half of the sliced potatoes into the creased dish, and spoon about half the sauce over the potatoes. Place the remainder of the potatoes in the dish, and spoon the remainder of the sauce over the second layer of potatoes. Sprinkle the shredded cheese over the top layer of potatoes, and place the dish in the oven.
Bake at 350 for about an hour, or until the potatoes are fully cooked. Keep watch on the potatoes, making sure the cheese on top doesn't burn. If the cheese gets too dark, cover loosely with foil and continue baking until the potatoes are fully cooked and a fork pierces them easily.
Cool slightly before serving. Top with minced parsley. Enjoy!
Notes
Scalloped potato add-ins to try:
Chives or scallions, or even finely chopped fresh onion
Sprinkle with breadcrumbs on top during the last 15 minutes of baking
Add finely diced sage, thyme, or rosemary to the sauce
Stir in some salsa to the sauce for a fun twist
MORE cheese (try a three-cheese combo!)
Feta and wilted baby spinach
Bacon bits
Diced ham
More hot sauce
Fresh tomatoes baked right into the dish for a burst of flavor and nutrients (small grape or cherry tomatoes work great, as well as thinly sliced large tomatoes - add these with the potatoes, don't stir them into the sauce!)
