Preheat your oven to 180°C (160°C fan/ Gas Mark 4).
Melt the Jersey butter in a large saucepan over medium heat. Add the chopped shallots and cook until softened, about 5 minutes. Add the minced garlic and cook for another minute until fragrant.
Stir in the plain flour and cook for 1-2 minutes, stirring constantly to form a roux.
Gradually whisk in the Jersey milk, a little at a time, until the sauce is smooth and thickened. Stir constantly to prevent lumps from forming.
Stir in the double Jersey cream, chopped fresh thyme, a pinch of grated nutmeg, salt, and black pepper. Bring to a gentle simmer and cook for 5 minutes, stirring occasionally.
Lightly grease an oven-safe dish.
Arrange a layer of sliced Jersey Royal potatoes on the bottom of the dish, overlapping slightly. Top with a layer of quartered artichoke hearts.
Pour about one-third of the creamy sauce over the potatoes and artichokes.
Repeat layers of potatoes, artichokes, and sauce until all ingredients are used, finishing with a layer of sauce.
Sprinkle the grated Parmesan cheese over the top (optional).
Bake in the preheated oven for 30-40 minutes, or until the potatoes are tender and the top is golden brown and bubbly.
Remove from the oven and let it rest for 5-10 minutes before serving.
Dollop spoonfuls of pesto over the gratin just before serving.

For extra flavour, add a bay leaf to the creamy sauce while simmering, then remove it before layering the gratin.
If the top of the gratin is browning too quickly, cover it loosely with foil during the last 10-15 minutes of baking.
The gratin can be prepared ahead of time and stored in the refrigerator for up to 24 hours. Add an extra 10-15 minutes to the baking time if baking from cold.
Use seasonal vegetables like asparagus or broad beans alongside or in place of artichokes.
For a richer flavour, use grated Gruyère cheese in place of or in addition to Parmesan.
