So here’s the deal — potatoes are always welcome. It doesn’t matter the meal or the occasion, there’s always a place for potatoes. How many foods can you say that about? Not many!

Of course, when paired with cheese they’re probably even more welcome and that’s just what this casserole does — pairs those delightful little tubers with a cheesy, creamy, savory sauce and uses the magic of the oven to make them as bubbly and comforting as can be.

This is an ideal side dish for potlucks and company because it’s so crowd-pleasing. It’s homey and unfussy but it still has layers of nice flavor and that’s because it’s not just potatoes and cheese, it’s a whole lot of other stuff too. Like onions and garlic that you soften in a skillet first before you stir in some flour that will later thicken the sauce. That sauce is largely made up of chicken broth so it’s not too creamy but there’s half and half to keep the creamy balance.

Once that’s thick, you remove it from the heat and stir in the sour cream and then mix that creamy goodness with the potatoes, some sharp cheddar, and green onion and then it’s time to bake. It’ll be bubbly and golden, with bite-sized cubes of tender potato surrounded by creamy cheddar. Heaven in a baking dish, more or less.
