A gratin dish or an 8×8 inch baking dish is a must. You’ll also want a large bowl for tossing veggies. A small bowl for mixing the topping helps too. Simple tools, big results!

Crafting Your Perfect Zucchini and Summer Squash Gratin
Making this gratin is a joyful process. It’s truly easier than you think! First, get your oven ready. Preheat it to 375°F (190°C). Then, lightly grease your gratin dish. An 8×8 inch baking dish works perfectly too.
Next, grab a large bowl. Toss your thinly sliced zucchini and summer squash in there. Add the olive oil, minced garlic, salt, and pepper. Make sure everything is nicely coated. This step adds so much flavor to your Zucchini and Summer Squash Gratin.
Now, let’s build those beautiful layers. Arrange half of the squash mixture in a single layer in your prepared dish. Try to make it even. Pour half of the heavy cream over these vegetables. Then, sprinkle with half of the Parmesan and Gruyere cheeses. Oh, the cheesy goodness!
Repeat these layers. Add the remaining squash, then the rest of the cream. Finish with the remaining cheeses. This layering creates that wonderful texture. It makes every bite delicious. In a small bowl, combine your panko breadcrumbs and chopped fresh parsley. Sprinkle this evenly over the top. This will give us that perfect golden crust.
Bake your gratin for 25-30 minutes. You want the vegetables to be tender. The topping should be golden brown and bubbly. Keep an eye on it! Once it’s ready, take it out. Let it rest for a few minutes before serving. This resting time is important. It helps the gratin set. Enjoy your amazing Zucchini and Summer Squash Gratin!
Expert Tips for a Flawless Zucchini and Summer Squash Gratin
Want your gratin to be absolutely perfect? Here are my best tips. First, slice your squash uniformly. This helps everything cook evenly. A mandoline slicer makes this super easy. For an extra layer of flavor, try adding a tiny pinch of nutmeg to the cream. It’s a secret ingredient! To get that perfect golden-brown topping, you can finish it under the broiler for a minute or two. Just watch it closely so it doesn’t burn. These little touches make your Zucchini and Summer Squash Gratin truly shine.
Storing and Reheating Your Zucchini and Summer Squash Gratin
Sometimes there are leftovers, which is a good thing! To store your Zucchini and Summer Squash Gratin, let it cool completely. Then, cover it tightly with plastic wrap or foil. You can keep it in the refrigerator for up to 3 days. For longer storage, you can freeze individual portions. Wrap them well in freezer-safe containers. They’ll last for up to 2 months.
To reheat, thaw frozen portions in the fridge overnight. Then, warm in a preheated oven at 350°F (175°C). Cover it loosely with foil. This keeps it from drying out. Bake until heated through. You want to maintain that lovely texture. Enjoy your delicious gratin even days later!

Common Questions About Zucchini and Summer Squash Gratin
I get a lot of questions about this gratin. Here are some of the most common ones. I hope these answers help you too!
Can I make Zucchini and Summer Squash Gratin ahead of time? Yes, absolutely! You can assemble the entire gratin. Just cover it tightly. Keep it in the refrigerator for up to 24 hours. Then, bake as directed when you’re ready to serve. Let it come to room temperature first for even cooking.
What can I substitute for Gruyere cheese? If you don’t have Gruyere, don’t worry. Swiss cheese or even a sharp white cheddar would work nicely. They offer a similar nutty flavor. The goal is a good melting cheese. It adds that lovely gooeyness to your Zucchini and Summer Squash Gratin.
Can I add other vegetables to this Zucchini and Summer Squash Gratin? Of course! This recipe is very flexible. Thinly sliced potatoes, bell peppers, or even mushrooms would be delicious. Just make sure they are sliced thinly. This helps them cook at the same rate as the squash. Experiment and make it your own!
