Ingredients

4 tablespoons salted butter divided
1 medium onion thinly sliced
1 garlic clove peeled and minced
1 cup ritz crackers roughly crushed (
4 cups mashed potato 1 ¾ pounds
½ cup grated parmesan cheese
¼ teaspoon kosher salt
¼ teaspoon freshly ground black pepper
1 cup 8 ounces shredded sharp cheddar cheese
3 tablespoons minced fresh parsley

Instructions

Preheat the oven to 400°F and lightly grease a 9-by-13-inch baking dish.
Heat a skillet over medium heat and add 2 tablespoons of the butter and the sliced onion. When butter is melted, stir and reduce the heat to low. Cook for 2 minutes then add the garlic cloves and cook, stirring occasionally, for 8 minutes. Remove the skillet from the heat and stir in the cracker crumbs.
While onions are cooking, melt the remaining 2 tablespoons of butter.
In the baking dish, combine the mashed potato and the parmesan cheese in the baking dish. Season with salt and pepper. Spread the potato mixture into an even layer in the baking dish and sprinkle the cheddar on top.
Bake in the oven until the cheese melts and is nicely browned, about 15 minutes.
Remove the casserole from the oven and top with the cracker and caramelized onion topping.
Garnish with the parsley and serve hot.

Notes

If you're wondering what type of potatoes to use for mashing and turning into this decadent casserole, the best choices are Yukon gold potatoes or Russet potatoes because they make the best mashed potatoes.
You can make this casserole several days ahead. Store it covered in the refrigerator for up to 5 days. You can even freeze itfor up to 1 month, but be warned that potatoes can become grainy when they're frozen.
