Preheat the Oven: Begin by preheating your oven to 375°F (190°C). A properly heated oven ensures even cooking.
Prepare the Cream Mixture: In a mixing bowl, combine heavy cream, milk, minced garlic, salt, and pepper. Stir well until blended.
Grease the Baking Dish: Take a baking dish and grease it with butter to prevent sticking and add a bit of extra flavor.
Layer the Ingredients: Place half of the sliced potatoes in the dish, then pour half of the cream mixture over them. Follow this with half of the cheddar and Parmesan cheese.
Repeat the Layers: Next, layer the remaining potatoes, cream mixture, and top with your remaining cheeses. If you want a little extra crunch, sprinkle some breadcrumbs on top.
Bake: Cover your dish with foil and bake for about 45 minutes. Then, remove the foil and continue baking for an additional 15-20 minutes until the top is golden and the potatoes are tender.
Cool and Serve: Allow the dish to cool slightly before serving. Enjoy this comforting delight with your favorite main course
