Instructions

Preheat the oven

Preheat your oven to 375°F (190°C).

Pro tip: A properly preheated oven ensures even cooking.

Prepare the baking dish

Lightly grease a 9x13-inch (23x33 cm) baking dish with butter or cooking spray.

Layer the vegetables

Arrange half of the potato slices in a single layer on the bottom of the dish. Follow with layers of zucchini, carrots, and bell pepper. Repeat the layering with the remaining vegetables.

Pro tip: Overlap the slices slightly for even coverage.

Prepare the sauce

In a saucepan, combine the heavy cream, milk, minced garlic, thyme, salt, and pepper. Heat over medium heat until just beginning to simmer, then remove from heat.

Pro tip: Avoid boiling the mixture to prevent curdling.

Pour the sauce

Evenly pour the cream mixture over the layered vegetables, ensuring even distribution.

Pro tip: Gently shake the dish to help the sauce settle between the layers.

Add the cheese

Sprinkle the grated Gruyère cheese over the top of the vegetables.

Pro tip: For extra flavour, mix in some Parmesan cheese.

Bake the gratin

Place the baking dish in the preheated oven and bake for 40-45 minutes, or until the top is golden brown and the vegetables are tender when pierced with a fork.

Pro tip: Let the gratin cool for 5 minutes before serving.

Serving Suggestions

Serve the vegetable gratin warm, straight from the oven, as a delightful side dish to roasted meats or as a vegetarian main course. Pair it with a crisp green salad and a glass of white wine for a complete meal. This gratin can be prepared ahead of time and refrigerated for up to two days before baking. Store leftovers in an airtight container in the refrigerator for up to three days, and reheat in the oven to maintain its delightful texture.
