This post originally appeared in December 2012 but I’ve updated it with newer pictures and updated recipe formatting. All the delicious flavors of this easy Garlic Herb Mashed Potatoes Casserole remain the same–still one of our favorites!
It’s been a long time since I’ve written a make-it-ahead post but this is one I can’t wait to share with you. It is one of our family’s favorites and I finally remembered to take pictures so I could share with you. This is a recipe I found several years ago on the forum for the Cooking Among Friends cookbook page (which it looks like the forums no longer exist)
By the way, you can read my review of that book here—it’s what helped me decide to start my freezer meal exchange group! Or check out my list of favorite freezer cooking cookbooks here.
Ok, back to the potatoes. My family loves mashed potatoes and we love garlic mashed potatoes even more! Who would have thought that you could not only make mashed potatoes ahead of time but that you could freeze and reheat them for later? Yes indeed you can! I have made this recipe more times than I can count and have shared it often also with my freezer exchange group members. It is always a huge hit!
The garlic herb cheese spread can actually be made up and frozen separately to use in all sorts of other ways if you like. I pretty much always just make it for these mashed potatoes. The nice thing is that it makes too casserole size dishes so there it plenty to go with your favorite entrée. It makes 8 servings per container so you can divide it up in half again to make four casseroles instead of two.
Y’all, you HAVE to make this recipe. Once you do, you’ll want to keep a casserole on hand in the freezer at all times. Now on to the recipe:
