🔪 How To Make Potato And Zucchini Au Gratin

1. For this easy zucchini au gratin recipe I used 5 smaller potatoes and about 1 ½ zucchini. You can slice them with a knife but for the even slices I recommend to use a mandolin slicer. Slice the potatoes into ⅛ inch slices and zucchini into ¼ inch slices.

2. Grease 8 x 6 baking dish and arrange sliced vegetables in a circular pattern in a dish, overlapping slightly. 

3. 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.

4. Pour the mixture evenly over the vegetables. 

5. Sprinkle with grated Gruyere or Parmesan cheese.

6. Now all you have to do is cover the easy Zucchini Au Gratin with a foil, pop it in the oven and bake for 40 minutes. Then remove the foil and bake for 10 more minutes.

🧀 Best cheese for Zucchini Au Gratin

For the gratin recipes I prefer using Gruyere as it melts nicely and has a beautiful nutty and earthy flavor. 

As an alternative, you can use Mozzarella cheese or Monterey Jack. Provolone cheese would be another good option.

👩🏻‍🍳 Chef's Tip to make this recipe perfect

Several readers commented that their Courgette Gratin comes out watery because zucchini releases too much liquid.

I've never had this issue before, but to be on the safe side, I recommend salting zucchini before cooking. This will help to pull a little bit of water out of zucchini. 

Here's how to do it:

After you sliced the zucchini, sprinkle them with about ¾ teaspoon of salt and let them rest for about 10 minutes in a colander. Set the colander over a sink or a bowl.

After that, pat dry the zucchini with a paper towel and proceed to the next cooking step.

💭 Frequently Asked Questions

📋 Make Ahead instructions

If you plan to make Potato Zucchini Gratin Bake for the holiday table or potluck, 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.

If you follow these make-ahead instructions, just make sure to pre-salt the zucchini. Otherwise, as the vegetables sit in a creamy sauce, they might release lots of liquid even before baking and it will result in soggy casserole.

📖  Scalloped Zucchini Casserole Variations

This is such a simple recipe and it's delicious as is. However, if you want to spruce things up, here's what I recommend:

• squash. In this recipe you can use different types of squashes: butternut squash, yellow or green squash. If you use butternut squash, there's no need to pre-salt it.
• bread crumbs. Sprinkle some Panko breadcrumbs on top of cheese and drizzle with one tablespoon of melted unsalted butter. Delicious crispy top is guaranteed;

♨️ Storing And Reheating

You can store this easy Zucchini Au Gratin covered in a refrigerator for 2-3 days. Reheat in a microwave.

Since, it's a potato and cream-based dish, I wouldn't advice to freeze it.
