How to Make Potato and Celeriac Gratin
Infuse the cream mixture: In a saucepan, combine the milk, double cream, butter, halved garlic bulb, thyme, and bay leaves. Heat gently and let infuse for 1 hour, allowing the flavors to meld beautifully. Strain the mixture and reheat to prepare for the next step.
Slice the potatoes and celeriac: While the cream is infusing, finely slice the potatoes and celeriac using a sharp knife or mandoline. This step helps them cook uniformly and absorb the creamy goodness.
Simmer the vegetables: Add the sliced potatoes and celeriac to the hot cream mixture. Simmer gently for 10 minutes, stirring occasionally to prevent sticking and ensure even coating.
Transfer to the baking dish: Pour the creamy mixture into a large buttered ovenproof dish. Neatly arrange the top of the bake for an inviting presentation that will impress your guests.
Bake in the oven: Place in a preheated oven at 180°C (fan 160°C/gas 4) and bake for 30 minutes or until golden brown on top. Afterward, reduce the temperature to 140°C (fan 120°C/gas 1) and cook for an additional 30 minutes until fully tender.
Optional: For an added crunch, top with freshly grated Parmesan before the final bake.

Additionally, slice the potatoes and celeriac a day ahead; store them submerged in cold water to prevent browning. When you’re ready to cook, simply reheat the cream mixture and follow the original cooking instructions for the gratin. This way, you ll save precious time on busy weeknights while still enjoying a dish that s just as delicious as if made from scratch!
