A comforting and flavourful gratin featuring vibrant purple sprouting broccoli, creamy Jersey milk, and tender potatoes.
Preheat oven to 180°C (350°F). Grease a 9x13 inch baking dish.
Heat olive oil in a large pan over medium heat. Add the garlic and sauté for 1 minute until fragrant.
Add the purple sprouting broccoli to the pan and sauté for 5 minutes, until slightly softened. Season with salt and pepper.
In a separate saucepan, melt the butter over medium heat. Add the Jersey milk and nutmeg. Bring to a simmer, then remove from heat. Season with salt and pepper.
Arrange a layer of potato slices in the prepared baking dish, slightly overlapping. Season with salt and pepper.
Top with half of the sautéed broccoli. Pour half of the milk mixture over the broccoli and potatoes.
Repeat with another layer of potatoes, seasoning, the remaining broccoli, and the remaining milk mixture.
Sprinkle the grated Parmesan cheese evenly over the top.
Bake in the preheated oven for 40 minutes, or until the potatoes are tender and the top is golden brown and bubbly. Let it rest for 5-10 minutes before serving.

For a crispier top, broil the gratin for the last 2-3 minutes of cooking, watching carefully to prevent burning.
You can substitute other cheeses for the Parmesan, such as Gruyère or mature cheddar.
Add a pinch of chili flakes to the milk mixture for a little bit of heat.
If the potatoes are very dry, you can soak them in cold water for 30 minutes before layering to help prevent them from drying out during baking.
