Thinly slice the onions. Dice the ham into bite-sized pieces. Peel the potatoes and cut them into slices that are no more than 1/4 inch thick. (If you're not going to assemble the casserole right away, keep potato slices in a bowl of water to prevent them from turning brown, then pat them dry with paper towels before layering them with the other ingredients.) Grate the cheese on the largest holes of your box grater. Mince the parsley.

Tip

A mandoline makes quick work of all the slicing required. Get a mandoline with a variety of attachable blades, so you can slice the potatoes and onions and even shred the cheese with the same tool. Always be exceedingly careful and wear safety gloves when working with a mandoline to prevent cuts.

Pour the mushroom soup and milk into the bowl you used for the onion, cheese and ham. Add the salt, pepper, garlic salt and all of the parsley except for about 1/2 teaspoon; reserve this to sprinkle on top when the dish is finished. Whisk everything together until it's smooth.

Tip

The quality of mushroom soup you choose will affect every bite of the finished casserole. When in doubt, opt for the classic: Campbell's Cream of Mushroom. Since the cheese and ham should already be quite salty, low-sodium Cream of Mushroom soup may be a better choice if you're trying to limit your salt intake. Alternately, create a different flavor profile by using mushroom and roasted garlic soup, or use a different condensed soup like cream of onion.

5. Cook the Casserole

6. Let rest and serve

The potatoes will be piping hot, so allow them to sit for at least 10 minutes after turning off the cooker. This also gives all those juices one last chance to soak into the potatoes. Serve in bowls or on plates, and enjoy!
