Preheat your oven to 375°F (190°C) and grease a 9x13-inch baking dish or equivalent-sized casserole dish.
Cut the cauliflower into bite-sized florets and rinse them thoroughly under running water.
Fill a large pot with water, bring it to a boil, and lightly salt it. Add the cauliflower florets and boil for 5-7 minutes, or until slightly tender. Drain the cauliflower and set it aside.
In a medium saucepan, melt 3 tablespoons of butter over medium heat. Once melted, whisk in the flour to form a smooth paste and cook for 1-2 minutes, stirring constantly to remove the raw flour taste.
Gradually pour in the milk while whisking to ensure no lumps form. Continue to cook and stir the sauce for 4-5 minutes, or until it thickens to a creamy consistency.
Stir in the salt, black pepper, and nutmeg (if using). Remove the saucepan from heat and mix in the cheddar cheese and Parmesan cheese, reserving a handful of cheddar for topping. Stir until the cheeses are fully melted and the sauce is smooth.
Spread the cooked cauliflower evenly in the prepared baking dish. Pour the cheese sauce over the cauliflower, ensuring all the florets are coated.
In a small bowl, combine the breadcrumbs with 1 tablespoon of olive oil and the remaining tablespoon of butter (melted). Mix well, then sprinkle the breadcrumb mixture evenly over the top of the casserole.
Sprinkle the reserved cheddar cheese over the breadcrumbs for an extra cheesy topping.
Bake in the preheated oven for 25-30 minutes, or until the top is golden and bubbly.
Remove from the oven and let the gratin cool for a few minutes before serving. Garnish with freshly chopped parsley if desired.
