Timing
Preparing this Zucchini and Yellow Squash Au Gratin takes about 15 minutes, followed by 30 minutes of baking time, totaling 45 minutes. This is approximately 20% less time than the average gratin recipe. With minimal effort, you can bring a delicious dish to the table that’s worthy of a place in any gathering!
Step 1: Preheat and Prepare Your Baking Dish
Begin by preheating your oven to 375°F (190°C). While it heats up, grease a medium-sized baking dish with olive oil to prevent sticking.
Step 2: Layer Your Vegetables
Arrange a layer of zucchini and yellow squash slices at the bottom of the baking dish, alternating them to create a beautiful pattern. This not only looks appealing but also helps even cooking.
Step 3: Make the Cream Mixture
In a mixing bowl, combine the heavy cream, minced garlic, salt, pepper, thyme, and half of the cheddar cheese. Whisk until blended. This mixture will give your dish a rich, creamy texture.
Step 4: Assemble the Gratin
Pour half of the cream mixture over the first layer of vegetables. Add another layer of zucchini and yellow squash, followed by the remaining cream mixture. Top with the rest of the shredded cheddar and all the grated Parmesan cheese. Don’t hold back on the cheese; this is what makes it truly decadent!

Step 5: Bake the Gratin
Cover the baking dish with aluminum foil and place it in the preheated oven. Bake for 20 minutes, then remove the foil and let it bake for an additional 10 minutes until the top turns golden brown and bubbly. This final step adds that delightful crispness.
