Rich, creamy, flavorful, cheesy and so satisfying, this Potato and Zucchini Gratin is an ultimate comfort food side dish for any type of meal or occasion. Very easy to make and so delicious! 
Potato Zucchini Gratin
One of my favorite way to use zucchini is to transform it into a gratin. A few years ago I’ve shared with you my foolproof Eggplant Gratin that is still in top of my best performing posts.
Today’s recipe is another winning dish. After trying it once, my husband couldn’t stop complimenting me. It was that good.
The secret to my Baked Potatoes And Zucchini is a simple sauce made with cream, garlic, herbs de Provence and a sprinkle of Gruyere cheese. This garlic enriched sauce penetrates the vegetables making them flavorful, soft and luscious.
And just like my Cauliflower Gratin or creamy Chicken Gratin which is one of my recently discovered comfort foods, this Potato and Zucchini Gratin will also fill your kitchen with warm and comforting flavors.
And one thing you can be sure of. Once you try my scrumptious Potato And Zucchini Casserole , you’re gonna want seconds.
Imagine the side dish that goes with everything. This Potato And Zucchini Gratin is the recipe that pairs great with meat, fish and can also be prepared ahead for the potlucks.
The zucchini potato recipe takes minutes to put together which is especially handy during holidays when you need to prepare lots of food but don’t wish to spend the whole day in the kitchen.
How To Make Potato Zucchini Gratin
For this recipe I used 5 smaller potatoes and about 1 1/2 zucchini. You can slice them with a knife but for the even slices I recommend a mandolin. Slice the potatoes into 1/8 inch slices and zucchini into 1/4 inch slices.
Grease 8 x 6 baking dish and arrange sliced vegetables in a circular pattern in a dish, overlapping slightly. 
In a tall measuring glass combine half and half (you can also use cream if you like), herbs de Provence, salt, pepper and garlic pushed through a garlic press. Give everything a nice whisk.
Pour sauce over the vegetables. 
Sprinkle with grated Gruyere or Parmesan cheese.
For these types of recipes I prefer using Gruyere as it melts nicely and has a beautiful nutty and earthy flavor. 
Now all you have to do is cover the dish with a foil, pop it in the oven and bake for 40 minutes and then remove the foil and bake for 10 more minutes.
If you plan to make Potato And Zucchini Gratin for the holidays table, you can arrange everything in the baking dish in the morning, cover with a foil and refrigerate for a few hours or until you’re ready to bake it.
