Root Vegetable Gratin
Made with a medley of fresh root vegetables, this is a real comfort dish. Each bite is a burst of flavour, with the smoothness of the rich sauce complementing the root vegetables. Whether you’re a vegetarian or simply looking to add more vegetable goodness to your meal, our root vegetable gratin is a must-try baked on the Big Green Egg.
The first time we cooked this, we used parsnips, sweet potato and beetroot. Â The second time, we added some celeriac. Â The choice of vegetables is endless; you could use swede, turnips, or carrots. Â Just ensure the vegetable rounds are all approximately the same size.

Ingredients
- 1 large sweet potato, peeled
- 3 parsnips, peeled
- 3 small beetroots, peeled
- 1 clove of garlic
- 1 tbsp thyme, fresh
- 200ml double cream
- 110g parmesan
- 25g gruyere cheese
- salt and ground black pepper to taste
Method
- Setup your Big Green Egg for an indirect cook with the stainless steel grid on top of your ConvEGGtor. To that, add your baking stone. Set your Egg to 180°C.
- Take each of your vegetables, trim the ends off and slice into very thin rounds. Â You could use a mandoline but if you’re cutting by hand just aim to cut them all to a similar thickness to allow even cooking.
- Place each vegetable rounds into its own bowl and pour over 50ml of double cream and some grated parmesan with a bit of thyme. Â Add salt and pepper to season. Â Give it a stir; you’re looking for the vegetables rounds to be well coated. Â Be slightly less generous with the cream when coating the beetroot as this will ensure that the pink colour does not bleed as the beetroot cooks.
- Take the first vegetable and create a stack, place them in the baking dish, repeat this with the remaining vegetables, creating rows of vegetables until your dish is full.
- Pour the remaining cream and sprinkle the remaining parmesan over the vegetable rows. Â Cover with foil.
- Place in the Egg and cook for about 40 minutes or until vegetables are soft.
- Uncover the dish and sprinkle over the grated gruyere. Â Bake for a further 20 minutes, until vegetables are ready and the top of the gratin has lightly browned.
- Remove from the heat and sprinkle with some fresh thyme leaves.
