Scalloped Potato Gratin

Recipe Description

The secret ingredient of my delicious Scalloped Potato Gratin is the mushroom soup, which adds oodles of creamy mushroom flavor. You might remember my ongoing hunt for great potato sides to satisfy my little ones’ potato cravings! Well, I discovered another treasure!

This scalloped potatoes with mushrooms soup recipe is creamy, tasty and the ultimate comfort food. It might sound a bit strange using mushroom soup, but I was thinking of gratin recipes, and then trying to make them easier! And it really works – the potatoes soften in the soup and absorb all the wonderful mushroom flavor (used a condensed soup for an even richer taste).

To make my Scalloped Potato Gratin, you will need the following ingredients:
