This Broccoli and Cauliflower Gratin is one of my all-time favorite Christmas side dish recipes. It is not only easy to make, it’s really tasty too. I love this because I can make it in advance and simply cook it in the hot oven when I am ready to serve dinner.
Start by making a roux from butter and flour. Carefully whisk in milk. Simmer until the sauce thickens slightly. Remove from heat. Add nutmeg and cheese. Season to taste and pour over the vegetables in a prepared breaking dish. Sprinkle remaining cheese on top. Bake in the oven until golden brown on top and leave to stand for 10 minutes before serving.
To make my Broccoli and Cauliflower Gratin, you will need the following ingredients:
Preheat the oven to 375 °F. Lightly butter a baking dish.
Place the cauliflower and broccoli in the baking dish.
Melt 4 tablespoons of butter in a saucepan. Add 6 tablespoons of flour to the saucepan and stir to make a paste. Continue to cook for about 2 minutes.
Gradually whisk in 3 cups of milk. Simmer for 3-4 minutes, while whisking occasionally, until the sauce thickens slightly. Remove the saucepan from the heat.
Add ¼ teaspoon of nutmeg and 1¼ cups of the Gruyère cheese. Season to taste with salt and pepper.
Pour the sauce over vegetables in the baking dish and scatter the remaining ¾ cup of cheese over the top.
Cover the baking dish loosely with aluminum foil. Bake for 15 minutes. Remove from the oven and take off the foil. Return to the oven and bake for 20-25 more minutes until the vegetables are tender and the top is golden brown.
Leave to stand for around 10 minutes before serving alongside your Christmas dinner.
