A lightened up version of my favorite Cheesy Potato Casserole so I don’t have to feel so guilty about loving it!

Healthier Cheesy Potato Casserole | Persnickety Plates

The older I get, and the more cooking I do, I try to avoid making dishes that involve canned soup. I just don’t like it. It kinda gives me the creeps actually. It’s so jiggly. ha. But, once a year, I do, very much, enjoy eating my aunt’s cheesy potato casserole (it’s actually the first thing I blogged). It’s so good, but I feel so guilty after I eat it. It’s butter, cheese, sour cream, potato chips…all together. In one beautiful dish.
This is a lightened up version of that recipe that you don’t have to feel so guilty for eating. The original recipe called for adding corn flakes to the top but I never have those on hand so I used Special K Cracker Chips. (Have you tried them? They’re really good.) I served it with some panko crusted chicken breasts and green beans. Next time I make this recipe, I’ll cut it in half. This makes a family size tray – way too much for just the two of us.

  • While the potatoes are cooking, in a large saucepan, combine the milk and cornstarch and whisk together. Over medium high heat, bring to a boil, whisking often, until it is bubbly and thick. It comes together quickly.

  • Spread the coated potatoes into the prepared baking dish evenly.

  • Bake for about an hour, until the potatoes start to brown and the edges are bubbling. Let cool for about 20 minutes before serving.
