Creamy Potato and Zucchini Au Gratin

Sharing is caring!

Creamy Potato and Zucchini Au Gratin is made with sliced potatoes, sliced zucchini, cheese, herbs, and cream. Then it is 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.  The best part? I cut the time in half than most recipes out there!

 

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! 

This recipe was posted a few years ago and I wanted to revive this one since it’s one of our all-time favorites! I even updated the photos as well. 

I don’t know about you, but if you love zucchini, this would be a great way to add some zucchini with this recipe. 

And to offer you another idea for a delicious casserole to serve for any weeknight or weekend dinner!

This Creamy Potato and Zucchini Au Gratin…

• makes a quick and super easy casserole.  

• all you need is potatoes, zucchini, some cream, parmigiana cheese, and fresh herbs.

• no need to layer the potatoes or anything… just mix it all together.

• easily bakes to perfection!  

• an Italian-style gratin makes an excellent side dish that pairs very nicely with any meat or fish entree.

• it’s pure comfort food.

Options to Serve with Creamy Potato and Zucchini Au Gratin…

This is an awesome side dish that goes perfectly with our:

• Oven-Baked Brisket
• Parmesan Crusted Chicken Cutlets (+Video)
• Baked Halibut and Sea Bass Oreganata
• Roasted Boneless Turkey Breast
• Easy Baked Swordfish
• Pork Tenderloin
• Perfect Filet Mignon Roast

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 them into the baking dish.

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

Here’s a Few Great Tips!   

• To cut the time in half, I also recommend using a handheld mandolin slicer for slicing the potatoes and zucchini. It’s faster, easier and you slice these veggies in minutes.
• Plus, as I mentioned, no need to layer the potatoes, just combine everything and transfer to a baking dish and bake.

• I prefer to use fresh herbs for this recipe. When I bring the herbs home I place them into a ziplock bag and pop them into the freezer. They freeze well, and for up to 1 month.
