Instructions

1. 1

   Heat the oven to 200 °C. Peel the potatoes, slice them thinly, parboil in salted water for 8 minutes and drain.

2. 2

   Break the broccoli into florets and blanch it with the potatoes for the last 3 minutes so it stays green and firm.

3. 3

   Finely dice the onion. Whisk the cream, milk, pressed garlic, diced onion, mustard and salt into a savoury sauce.

4. 4

   Layer the potatoes and broccoli in a baking dish, pour over the sauce and scatter with the grated cheese.

5. 5

   Bake for 25 to 30 minutes until the cheese is golden and the top is crisp. Let it rest briefly before serving.
