Creamy Potato and Zucchini Au Gratin
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.

Notes
If you use smaller potatoes, use more of them. Otherwise, you will have to reduce the amount of salt added to this recipe. Fresh herbs really makes the flavors pop in this casserole, so don't skip on them.

Can you prepare. Then freeze and cook from frozen state
Hi Barb, That is a good question. We prefer to prepare and bake the gratin first, then allow it to cool, cover it with aluminum foil, and freeze it. Then when you want to serve it, allow the gratin to fully thaw on your counter or the night before in your refrigerator. Reheat in the oven until it’s thoroughly heated through. I hope this helps! Thanks for making our gratin recipe, it’s our favorite! ENJOY!! 🙂
This is the perfect side dish to serve with an Easter ham.
Yes, we agree. Thanks so much for stopping by! Have a great week. 🙂

What a scrumptious way to eat zucchini. I need to remember your tip on freezing fresh herbs, seems like I'm always wasting them.
Hi! We are so happy and excited to hear that our creamy potato and zucchini casserole worked for you and now you are using it as part of your catered meal for October. That's so exciting and terrific news for us! We thank you for stopping by and hope you continue to try our recipes in the near future!
Warmly, Anna and Liz
We found this quite by accident. The posting is almost 2 years old, so no one will ever see our comment. But, it is a real winner and we loved it! On the first trial, I had the time so I arranged the slices, but you're right; it is not necessary. Most importantly, this potato zucchini dish also made the final cut for our self-catered, LGBT wedding to he held in early October. We're also serving trout, we've tested them together and we could not be more pleased. And all from a web-surfing accident while looking for something wholly unrelated. We thank you and our guests thank you.
