Creamy Potato and Zucchini Au Gratin – Italian Style!

Creamy Potato and Zucchini Au Gratin ~ is made with sliced potatoes, sliced zucchini, cheese, herbs and cream, then baked to create an Italian Style Au Gratin!  This is a creamy version for a gratin and a twist on our Mom’s recipe for her roasted potatoes and zucchini side dish.  Since everyone loves potatoes, I wanted to turn her recipe into a creamy version, making this the ultimate creamy potatoes and zucchini au gratin super easy!  The best part is, I cut the time in half than most recipes out there!

This recipe was posted a few years ago and I wanted to revive this one since it’s one of our all time favorite! I even updated the photos as well. I don’t know about you, but if you love zucchini, I thought this would be a great way to use zucchini with this recipe.  And to offer you another idea for a delicious casserole to serve this Thanksgiving!

Creamy Potato and Zucchini Au Gratin is quick and super easy to make.  All you need is potatoes, zucchini, some cream, parmigiana cheese and fresh herbs.  Then bake it to perfection!  This Italian style gratin makes a delicious side dish that pairs very nicely with any meat or fish entree!

When I get home, I have about an hour (if I’m lucky) to get dinner on the table. So instead of layering the potatoes and zucchini, I just mix all the ingredients together and pour it into the baking dish.

Nothing fancy, but it works very well and you get the same creamy and tender texture results!

Also, to cut the time in half, I recommend to use a handheld mandolin slicer for slicing the potatoes and zucchini. It’s faster, easier and it rinses off clean in seconds.

Creamy Potato and Zucchini Au Gratin always turns out great!  One taste and you’ll be asking for seconds!

Here’s a Tip:   To make my life easier, I buy fresh herbs when I need them for a recipe, then put them into a zip lock bag and place them into the freezer.  This allows me to have fresh herbs anytime I need them.  They last in your freezer for about 1 month.
