    • Choose a firm, fresh cauliflower head. Make sure it is not too small or too large. As this will affect the cooking time. Avoid cauliflower that is soft, mushy, or has brown spots.
    • Blanch the cauliflower florets in boiling, salted water for 2-3 minutes, then drain and rinse with cold water. This will help the cauliflower become tender and ensure it cooks evenly in the oven.
    • Add milk gradually. Whisk in warm milk into the roux, stirring constantly to prevent lumps from forming. Cook the mixture over medium heat, whisking constantly until it thickens to a creamy consistency.
    • Use a good melting cheese, such as Gruyere, cheddar, or Parmesan. This will help creamy texture. For more, check out our ‘Types of Cheeses’ article.
    • You can make cauliflower gratin without cheese. Simply omit the cheese from the recipe or substitute it with a dairy-free cheese alternative to make this recipe vegan.
    • Make a creamy sauce. To make the creamy cheese sauce, use a combination of milk, cream, and cheese. You can also add in some garlic and herbs like thyme or rosemary to add more flavor to the sauce.
    • If the sauce is too thick, add more milk.
    • If the dish is too watery, you can try draining off the excess liquid or baking it for a few more minutes to evaporate the liquid.
    • Layer the cauliflower and sauce. In a baking dish, layer the cauliflower florets and pour the cheese sauce over them. Make sure to coat all the florets evenly.
    • Top the cauliflower with a mixture of breadcrumbs and grated cheese. This will create a crispy and golden-brown crust on top of the cauliflower.
    • Don't overcook the cauliflower. Otherwise, this will become mushy and lose its texture. Blanch the cauliflower for just 2-3 minutes before adding it to the sauce.
    • Let the cauliflower gratin rest for a few minutes after baking to allow the cheese sauce to settle and thicken. This will make it easier to serve and also enhance the flavor.
    • Serve the cauliflower gratin hot and garnish with some fresh herbs like parsley or chives.
