Step-by-Step Guide to Making Cheesy Cauliflower Bake

1. Preheat the Oven:
   • Preheat your oven to 400°F (200°C). This will ensure that the cauliflower roasts to perfection.
2. Prepare the Cauliflower:
   • Wash the cauliflower thoroughly and cut it into bite-sized florets.
   • Place the florets on a baking sheet and drizzle them with olive oil.
   • Season with salt and pepper, then toss the florets to coat them evenly.
3. Roast the Cauliflower:
   • Spread the cauliflower out on the baking sheet in a single layer.
   • Roast in the preheated oven for 20-25 minutes, or until the florets are tender and have a golden-brown edge.
4. Make the Cheese Sauce:
   • While the cauliflower is roasting, melt the butter in a medium saucepan over medium heat.
   • Add the flour to the melted butter, whisking constantly to create a roux. Cook for about 1-2 minutes, until the mixture is lightly golden.
   • Gradually add the milk to the roux, whisking continuously to prevent lumps. Bring to a simmer and cook until the sauce thickens, about 3-5 minutes.
   • Remove the saucepan from the heat and stir in the cheddar, mozzarella, and Parmesan cheeses until melted and smooth.
   • Add the garlic powder, onion powder, smoked paprika, and cayenne pepper (if using). Stir well to combine.
5. Combine and Bake:
   • Once the cauliflower is roasted, transfer it to a large baking dish.
   • Pour the cheese sauce over the cauliflower, ensuring all florets are well-coated.
   • Place the dish in the oven and bake for an additional 10-15 minutes, or until the cheese is bubbly and golden.
6. Garnish and Serve:
   • Remove the bake from the oven and let it cool slightly.
   • Garnish with fresh chopped parsley before serving.
