Step-by-Step Method
Preheat and prep the dish
Heat the oven to 375°F (190°C). Lightly grease a medium baking dish so nothing sticks.
Slice the potatoes
Peel the potatoes and slice them thinly. Keeping the slices similar in thickness helps them bake evenly.
Whisk the creamy sauce
In a bowl, whisk together mayonnaise, sour cream, milk, eggs, and mustard until smooth. Stir in parsley, salt, and pepper if you’re using them.
Coat the potatoes
Add the sliced potatoes to the baking dish, pour the sauce over, and gently toss so the slices are well coated.
Add the cheeses
Sprinkle the shredded melting cheese over the top, then finish with the grated Parmesan.
Bake and rest
Bake for 30 minutes, until set and lightly browned on top. Let it rest for 5 minutes, then slice and serve warm.
