Butternut Squash And Yukon Gold Gratin With Gruyere Cheese Recipes

Steps:

• Preheat oven to 350F degrees.
• Butter a 9X13 baking dish.
• Melt butter in large skillet over med-high heat- add onions and saute until deeply carmelized- about 20-30 minutes.
• Lay alternating layers of squash and potatoes in pan.
• Layer onions on top.
• Mix 1/2 and 1/2 and salt and pepper, pour over top.
• Cover tightly with foil and bake 90 minutes.
• Increase oven temp to 400F degrees.
• Mix breadcrumbs, sage and cheese in bowl.
• Sprinkle over Gratin.
• Bake uncovered until top is golden brown and crisp, about 30 minutes.

Steps:

• Heat the butter and oil in a large frying pan. Add the onions and cook slowly over a low-medium heat, stirring every now and then, for 10-15 mins until golden and soft.
• Meanwhile, put the garlic and half the sage in a saucepan, add the cream and milk, and heat gently, not allowing the mixture to boil, for 5 mins. Remove from the heat and set aside to cool for 10 mins, then fish out the sage and garlic. Stir in the mustard and season well.
• If cooking straight away, heat oven to 180C/160C fan/gas 4. Layer the pumpkin slices, onions, most of the cheese and the infused cream into a large baking dish, finishing with a layer of cream. Once you've used the ingredients up, scatter with the remaining cheese and put the remaining sage leaves on top. Cover the dish with foil and bake for 45 mins.
• Uncover the dish and increase the heat to 200C/180C fan/gas 6. Cook for a further 20-30 mins until golden brown and tender all the way through. Leave to cool for 10 mins before serving.
