Before we start into this delectable side dish, I need to make the following disclaimer.

Calories don’t exist on holiday feast day.

They just don’t. They can’t really. 😉

I’m teasing…there are ways to be smart about calories at a holiday feast…but I like to pretend they don’t count or exist. (hehe)

Making this calorie disclaimer is important with this recipe…but so is this one: this cheesy potato casserole goes a long way. Like, it will make 12 to 16 side dish servings, from a 9×13 inch baking dish. The more you divide, the smaller the servings, and then the fewer the calories…

There I go with the calories again.

Seriously, if you are counting calories and fat, use light sour cream and a little less cheese on top.

But, remember…they don’t count at holiday meals. 😛

OK…I’ll stop…and we’ll just move onto the recipe. K?

This one is inspired by my mom-in-love. She makes something similar for holiday meals. And boy, oh boy…

Here’s my version…
