• Meanwhile, in a large bowl, combine the onion mixture, sweet potatoes, celery root, Yukon Gold potatoes, cream, chicken stock, Gruyere, thyme, 1 tablespoon salt and 1 1/2 teaspoons pepper. Pour the mixture into the prepared baking dish and press lightly so the vegetables lie flat all the way to the edge.

Bake uncovered for 1 1/2 hours, until the vegetables are very tender when tested with a small knife and the top is browned and bubbly. Allow to set for 15 minutes and serve hot.

Steps:

• Roast the vegetables: Preheat the oven to 400 degrees. Place the cauliflower, carrots, and broccoli on a large baking sheet. Drizzle olive oil and sprinkle salt and pepper over the vegetables. Give them a toss to evenly coat them in seasoning and oil. Roast the vegetables for 15 minutes.
• Prepare the cheese sauce: While the vegetables are roasting, melt the butter in a large saucepan or French oven over medium heat. Once melted, add the onion and garlic and cook for 2 minutes, stirring occasionally. Stir in the flour until the mixture forms a clump. Gradually pour in the milk, whisking the mixture to incorporate it. Turn the heat up to medium-high heat and continue to whisk for 1-2 minutes until the sauce thickens. Turn the heat to low and stir in the cheese until melted. Add in the salt, pepper, and pinch of nutmeg and stir to incorporate.
• Bake the casserole: Add the roasted vegetables to the pan of cheese sauce. Stir to incorporate. Pour the vegetables in a casserole dish and sprinkle the breadcrumbs on top. Bake in the oven for about 10 minutes or until the breadcrumbs are golden brown.
