Root Vegetable Gratin Food

HERBY ROOT VEGETABLE GRATIN

Steps:

• Heat oven to 180C/160C fan/gas 4. Melt half the butter in a large saucepan, add the onion and cook until soft. Pour in the cream and milk, and add lots of seasoning. Add the sliced vegetables and gently simmer for 10 mins until the potatoes start to soften.
• Meanwhile, blend the herbs, garlic, most of the Parmesan and some seasoning in a food processor. Add the oil and blend again to form a paste.
• Tip a third of the creamy veg into a buttered baking dish, dollop over half the herb mix and spread out a little. Top with another third of the veg, followed by the remaining herb mix, then the rest of the vegetables. Dot the surface with the remaining butter and scatter over the reserved Parmesan. Bake for 1-1½ hrs until bubbling and golden, covering with foil for the final 30 mins if it's becoming too brown. Leave to rest for 10-15 mins before serving.

GRATIN OF CARROTS & ROOT VEGETABLES

Steps:

• Preheat the oven to 180C/gas 4/fan 160C and butter a shallow ovenproof dish. Layer the potatoes, then the parsnip in the bottom of the dish with two of the sliced garlic cloves and sprinkle over a little salt and half the rosemary. It's best to keep the potatoes buried under the other vegetables because they go black if they are on top of the gratin.
• Pour the cream and milk into a large saucepan, add the rest of the rosemary and garlic, the carrots and a little seasoning. Bring to the boil, then turn the heat to the lowest it will go and simmer for 3 minutes.
• Pour the carrots and cream over the other vegetables, and spread the carrots out. Sprinkle over the parmesan, cover with foil and bake for 40 minutes. Remove the foil and bake a further 20 minutes until golden and bubbly.

Steps:

• Peel the vegetables (or leave the potatoes unpeeled for more vitamin content). Slice all vegetables into rounds no more than 1/8" thick. Mince the garlic fine. Rub the bottom and sides of a large oval glass or ceramic casserole pan with some of the butter. Now lay the sliced vegetables in layers in the pan, using one type of vegetable per layer. Sprinkle each layer with salt and pepper to taste, then with minced garlic and grated Gruyere; dot each layer with pieces of butter. When all the veggies have been layered, pour in the milk to come halfway up the vegetable layers. Cover with foil and bake 30 minutes at 350 degrees. Remove the foil, dot the top of the casserole with the goat cheese, and bake 30 minutes more, or until vegetables are soft, cheese has turned golden, and the casserole is bubbly. Let it sit for 10 minutes, then sprinkle with the parsley and serve directly from the casserole.
