Blissed-Out Crispy Cheesy Broccoli Gratin

This crispy cheesy broccoli gratin is a sophisticated way to serve a family favourite, transforming the humble floret into a decadent side dish. By roasting the broccoli at a high temperature on a preheated tray, you achieve a wonderful depth of flavour and a slight char that pairs perfectly with the savoury topping. It is an excellent alternative to a traditional boiled side, offering a satisfying crunch that even the most reluctant vegetable eaters will enjoy.

Ideal for a Sunday roast or as a quick midweek accompaniment, this vegetarian-friendly dish combines sharp Cheddar and salty Parmigiano Reggiano with golden garlic butter breadcrumbs. The recipe is simple to prepare and focuses on texture, ensuring the broccoli remains tender while the topping provides a rich, brittle crust. Serve it immediately while the cheese is bubbling and the panko crumbs are at their absolute crispest.

Ingredients for Blissed-Out Crispy Cheesy Broccoli Gratin

  • 575g broccoli florets (I like leaving about 1 inch of the stem attached)

  • 2 tablespoons extra-virgin olive oil

  • 1 teaspoon kosher salt

  • 2 tablespoons unsalted butter

  • 2 garlic cloves, minced

  • 40g panko bread crumbs

  • 90g grated Cheddar cheese

  • 30g finely grated Parmigiano Reggiano cheese

Adjust one oven rack to the upper-middle position and another rack to the position. Place a rimmed sheet pan on the middle rack and preheat the oven to 204°C.

Toss the broccoli florets with the olive oil and salt in a medium-size bowl. Turn the broccoli out onto the hot sheet pan (it should sizzle!) and roast until the bottom of the florets are nicely browned, about 15 minutes.

Meanwhile, combine the butter and garlic in a ramekin and place it in the oven until the butter melts, 5 minutes. (Alternatively, combine them in a microwave-safe bowl and microwave on high power in 15-second increments, swirling between each, until the butter melts, 45 seconds to 1 minute.)

Place the bread crumbs in a medium-size bowl, add the butter-garlic mixture, and toss with a fork. Add the Cheddar and Parmigiano Reggiano cheeses and toss to combine.

Remove the sheet pan from the oven and sprinkle the broccoli with the cheesy bread crumb mixture. Turn the grill to high and place the sheet pan on the upper rack. Grill until the cheese is melted and browned, 1 to 2 minutes (watch the bread crumbs closely as grill intensities vary and you don’t want them to burn). Remove from the oven, transfer to a platter—making sure to scrape up all of the crispy, crunchy cheesy bits—and serve.
