Step by step recipe

Step 1 - ⌛ 30 min.

Wash 800 g potatoes, cut them into pieces and cook in a large pot of salted water until they are tender.

I used new potatoes here, if you don't have any, use the classic ones, but peel them.

Step 2 - ⌛ 4 min.

Drain the potatoes, then pour them into a salad bowl.

Add 4 tablespoons olive oil and mix well.

Preheat your oven to 200°C (390°F).

Step 3 - ⌛ 3 min.

Place a sheet of baking paper in a baking tray.

Spread the oiled potatoes on top, and place the cauliflower (here a small one) next to it, which you will also coat with olive oil with a brush.

Add salt and pepper.

Step 4 - ⌛ 30 min.

Bake for about 30 minutes, until the vegetables are golden brown.

Do not turn off the oven.

Step 5 - ⌛ 1 min.

Butter a casserole dish, and pour the potatoes in the bottom.

Step 6 - ⌛ 3 min.

Chop 1 spring onion (scallion)...

Step 7 - ⌛ 1 min.

...and place it on the potatoes.

Step 8 - ⌛ 2 min.

Add the roasted cauliflower cut into pieces.

Step 9 - ⌛ 2 min.

Pour the béchamel sauce on top.

Step 10 - ⌛ 3 min.

Finish by 50 g grated cheese and put in the oven...

Step 11 - ⌛ 25 min.

...for about 25 minutes.

Remarks

If you don't have a spring onion at step 6, replace it with a shallot or remove it.

As always with gratins, the proportions are very indicative, so feel free to adapt.

Keeping: 1 or 2 days in the refrigerator, protected by a stretch film.
