Creamy vegetable gratin

Gratin (oven-baked dish) is a celebration of vegetables: vegetables steam and roast simultaneously in creamy cheese sauce. The goal is for vegetables to be tender but not mushy, with cheese browned to a crisp on top. Works with any seasonal vegetable, the key is thin slicing and harmonious seasoning.

Instructions

1

Clean vegetables. Cut potato and carrot into wafer-thin slices, break broccoli into small florets.

Tip: Uniform cutting (e.g. with mandoline) ensures all vegetables cook at same time.
2

Throw broccoli and carrot into boiling salted water for 3 mins (blanching), then drain.

Tip: These vegetables are harder than courgette, pre-cooking helps even out the difference.
3

Mix cream with crushed garlic, oil, salt, and pepper.

Tip: Garlic flavour dissolving in fatty cream will permeate the whole dish.
4

In a bowl toss all vegetables with cream sauce and half the cheese, then pour into buttered baking dish.

Tip: No need to layer precisely, rustic arrangement allows sauce to penetrate pieces better.
5

Sprinkle top with remaining cheese. Cover with foil, bake at 180°C for 30 mins, then remove foil and brown until golden (another 10-15 mins).

Tip: Steam under foil softens vegetables, dry heat after removal caramelises cheese.

Recipe FAQ

The potato remained hard.
Potato softens harder in acidic medium (sour cream/cream). Cut very thinly, or parboil for 5 mins in salted water.
Too much liquid.
Courgette releases lots of water. Salt courgette slices beforehand, let stand 10 mins, then squeeze out excess water.
