- 1 cup whole milk
- 2 cloves garlic, minced
- 1 teaspoon fresh thyme leaves

Instructions
- Preheat your oven to 375°F (190°C). Butter a large baking dish generously to ensure nothing sticks.
- In a saucepan over medium heat, combine the heavy cream, milk, minced garlic, and thyme. Allow the mixture to come to a simmer, stirring occasionally, and then set aside.
- Arrange a layer of potato slices in the prepared baking dish, slightly overlapping them. Follow with a layer of squash slices.
- Pour a third of the cream mixture over the top, and sprinkle with a bit of Gruyère and Parmesan cheese.
- Repeat the layering process twice more, ending with a generous sprinkle of cheese on top.
- Season each layer lightly with salt and black pepper, keeping in mind that the cheese will add additional saltiness.
- Cover the dish with aluminum foil and bake for 30 minutes. Then, remove the foil and bake for another 20-25 minutes, or until the top is golden brown and bubbly.
- Let the gratin cool for at least 10 minutes before serving. This allows the flavors to meld and makes it easier to serve.
As you prepare this dish, remember my grandmother’s advice — cook with your senses. Listen to the gentle bubble of the cream, watch for that perfect golden hue, and savor the aroma that fills your kitchen.

Tips for Making the Best Rustic Harvest Squash & Potato Gratin
To achieve the perfect gratin, slice your vegetables uniformly for even cooking. A mandoline slicer can be a handy tool for this task. Also, don’t skimp on the cheese; it’s what gives the gratin its irresistible crust. If you’re feeling adventurous, add a dash of nutmeg to the cream for a subtle warmth that pairs beautifully with the squash.

Storage and Reheating Tips
If you have leftovers (though I doubt you will!), store them in an airtight container in the refrigerator for up to three days. To reheat, cover the gratin with foil and warm in a 350°F oven until heated through. Avoid using the microwave, as it can make the texture less creamy.
