This Sour Cream and Onion Smashed Potato Casserole is one of those recipes you’ll reach for over and over again. It just goes with everything so well and rounds out most any meal. It sort of celebrates the flavor combo of creamy sour cream with the tangy taste of onion and smothered potatoes. What could possibly be wrong with that? I particularly love it because it can be made in advance and chilled until I’m ready to bake it. There’s no meat in this dish so I can easily serve this when vegetarians are dining at my table and know they’ll be satisfied, too.
If this potato casserole is assembled in advance, you’ll need to bring it to room temperature prior to baking. If you’re in a hurry, add 10 minutes or so to the baking time. Have fun with the cheese using white or yellow cheddar, swiss, gruyere, muenster or whatever you have handy. This dish is low stress all the way around. At our house there’s no wrong cheese. Ever. Keep in mind when smashing the potatoes you’ll need to leave some bite size chunks behind for the scrumptious texture of these smashed potatoes. When I want to top these with a crispy topping, I sprinkle crushed crush sour cream and onion potato chips over the cheese on top. So simple, tasty and tummy filling it’s guaranteed there won’t be a spoonful left over.
