Hearty Swiss mountain vegetable gratin: layered broccoli, carrots, cauliflower, and sliced potatoes baked in seasoned garlic herb cream under a golden crust of aged Appenzeller cheese.
Parboil carrots, cauliflower, and broccoli in salted water for 4 minutes until tender-crisp; drain.
In a buttered gratin dish, layer the parboiled sliced potatoes and colourful vegetables.
Whisk cream, broth, minced garlic, nutmeg, salt, and pepper together and pour over the vegetables.
Scatter the grated Appenzeller cheese heavily across the top. Bake at 190°C (170°C fan) for 30 minutes until bubbling and golden.
