Preheat your oven to 400Β°F (200Β°C).
Cut the cauliflower into small florets and spread them on a large baking sheet. Drizzle with olive oil, and season with salt and black pepper. Toss to coat.
Roast the cauliflower for 20 minutes or until tender and slightly caramelized. Set aside.
In a medium saucepan, melt the butter over medium heat. Whisk in the flour and cook for 1-2 minutes until it forms a smooth paste, known as a roux.
Slowly pour in the milk, whisking constantly to avoid lumps. Cook over medium heat, stirring frequently, until the sauce thickens (about 5-7 minutes).
Stir in the prepared horseradish, Dijon mustard, and Gruyere cheese. Continue stirring until the cheese melts, then taste and adjust seasoning if needed.
Lower the oven temperature to 375Β°F (190Β°C).
In a greased 2-quart baking dish, layer the roasted cauliflower. Pour the cheese sauce evenly over the top.
In a small bowl, combine the Panko breadcrumbs, Parmesan cheese, and chopped parsley. Sprinkle the breadcrumb mixture evenly over the cauliflower and sauce.
Bake the gratin in the oven for 15-20 minutes, or until the top is golden brown and crispy.
Allow the gratin to cool for a few minutes before serving. Garnish with additional parsley if desired.
