- Preheat your oven to 375°F (190°C) and butter a 9x13-inch baking dish.

- Melt 4 tablespoons of butter in a saucepan over medium heat, whisk in flour until smooth and golden.
- Gradually add 1 cup of whole milk and 1 cup of cream, whisking until the mixture thickens (about 5-7 minutes).
- Season the sauce with onion powder, garlic powder, salt, and black pepper; simmer for about 3 minutes.
- Remove from heat and stir in mozzarella and cheddar until melted and smooth.
- Pour half of the cheese sauce over the potato slices, spreading evenly.
- Cover with aluminum foil and bake for 30 minutes.
- Remove foil, drizzle remaining cheese sauce on top, and bake uncovered for an additional hour.
- Check for doneness with a fork; let sit for 10 minutes before garnishing with parsley or dill.

Notes
