Ingredients
- Cauliflower and Broccoli: Fresh heads cut into florets to get the perfect tender bite without mushiness.
- Sharp Cheddar and Gruyère: A blend that melts smoothly and brings a deep cheesy flavour.
- Dijon Mustard and Nutmeg: Tiny additions that lift the sauce beyond ordinary comfort food.
- Parmesan and Breadcrumbs Topping: Gives that crave-worthy crisp golden finish every gratin deserves.
Instructions
- Get Everything Ready:
- Preheat your oven to a welcoming 200°C (400°F), gently greasing a 2-liter baking dish to keep the gratin from sticking.
- Prepare the Vegetables:
- Boil salted water until it sings, then immerse your cauliflower and broccoli florets briefly so they soften just right, still holding their shape.
- Make the Cheese Sauce:
- Melt butter till it gently bubbles, whisk in flour to form a smooth paste, then gradually add milk, stirring constantly until thick and creamy with the scent of warmth starting to build.
- Blend in Flavor:
- Off the heat, fold in cheddar and Gruyère cheese along with Dijon mustard and freshly grated nutmeg, stirring until melted into a luscious sauce that promises richness.
- Assemble the Gratin:
- Arrange your perfectly drained veggies in the dish, pour over the velvety cheese sauce, and sprinkle the Parmesan and breadcrumb mixture on top with a drizzle of olive oil ensuring a golden crust.
- Bake to Perfection:
- Slide it into the oven for 25 to 30 minutes until you see bubbling cheese beneath a crust that’s kissed by golden color. Let it rest briefly so every bite settles into cheesy comfort.

Keeping It Fresh
When making this gratin ahead, I tightly cover the unbaked dish with foil and refrigerate it. On baking day, add a few extra minutes to ensure everything is warmed through and the top crisps beautifully.
