Cauliflower Gratin, or Gratin de Chou-Fleur, is a classic comfort dish originating from France. It combines tender cauliflower florets enveloped in a creamy cheddar and Gruyère béchamel sauce, topped with a crispy breadcrumb crust. This dish is perfect for showcasing the versatility of cauliflower, transforming a simple vegetable into a decadent, cheesy delight. Whether served as a side dish or a main course, its rich flavours and textures will have everyone asking for seconds.

Instructions

Prepare the cauliflower

Bring a large pot of salted water to a boil. Add the cauliflower florets and blanch for 3-4 minutes, until tender-crisp. Drain well and set aside.

Pro tip: Ensure the cauliflower is drained thoroughly to prevent a watery gratin.

Make the béchamel sauce

In a medium saucepan over medium heat, melt the butter. Stir in the flour and cook for 1 minute. Gradually whisk in the milk, continuing to whisk until the sauce thickens, about 5 minutes.

Pro tip: Whisk constantly to avoid lumps forming in the sauce.

Add cheese to the sauce

Remove the béchamel from heat and stir in the cheddar and Gruyère until melted. Season with nutmeg, salt, and pepper.

Pro tip: Taste and adjust seasoning as needed.

Combine cauliflower and sauce

In a large mixing bowl, combine the drained cauliflower with the cheese sauce. Mix until the florets are well coated.

Prepare the topping

In a small bowl, combine breadcrumbs, olive oil, and parsley. Mix until breadcrumbs are evenly coated.

Pro tip: Use your hands to ensure even distribution of oil.

Assemble and bake

Preheat the oven to 190°C (375°F). Transfer the cauliflower mixture to a greased baking dish and spread the breadcrumb topping evenly over the top. Bake for 25-30 minutes until golden and bubbly.

Pro tip: Check the gratin halfway through baking to ensure the top isn't browning too quickly.
