💭Mashed Potato Casserole without Sour Cream
If you don't like the flavor of sour cream, you can definitely leave it out of this recipe. The casserole will still be flavorful! You could try adding the same amount of Greek plain yogurt. It will give you the same richness to the dish without the flavor of sour cream.
The yogurt will help add moisture and richness to the casserole so that it stays creamy while it's baking in the oven. It's a simple addition that makes a big impact!
