Carrots and Onions Au Gratin

01Method

1. 1

   Heat the oven to 350°F (175°C).

2. 2

   Add the carrots and onions to a pot, cover with lightly salted water, and bring to a boil. Cook for about 5 minutes until just tender. Drain well, then arrange half the vegetables in a baking dish. Scatter about three-quarters of the cheese over them, add the remaining vegetables, and finish with the rest of the cheese.

3. 3

   In a saucepan, melt the larger portion of butter over medium heat. Whisk in the flour until a smooth paste forms, then gradually pour in the milk, stirring continuously until the sauce thickens. Season with salt and pepper. Pour the sauce evenly over the layered vegetables and cheese.

4. 4

   In a small pan, melt the remaining butter and stir in the bread crumbs until combined. Distribute the mixture evenly over the top of the baking dish.

5. 5

   Bake for 20 minutes until the topping is golden and the dish is bubbling around the edges.
