Potato, leek and pea gratin

Thin potato slices get a brief head start on the hob, then bake with leek, peas and a gentle milk-and-cream-cheese sauce. Soft inside, lightly golden on top.

Why it works for children & what’s in it

Times are estimates for the base recipe. Larger quantities may take longer.

Step by step

Here’s how.

0 / 5
An easier way today.

Cut potato slices evenly to reduce differences in cooking time. A shallow dish cooks more predictably than a small, deeply filled one.

What you can prepare ahead

Promptly portion and refrigerate the finished bake if eating it the next day. Do not leave it partly cooked at room temperature for a long time.

Got interrupted? Tick off each step as you finish, so you can find your place again here.

When there is room for it today

Helping is welcome. Watching is too.

Your child can brush oil over the cold dish and sprinkle cheese. Adults handle knives, boiling milk and the oven.

For your family table

Adapt for younger eaters.

Fully soften potato slices and leek. Remove firm cheese edges if needed, crush peas and check the temperature inside the food.

The nutrients in these ingredients.

Calcium

Important for building bones and teeth, especially during growth.

Protein

A building block children need for growth and for making body tissues.

Fibre
Here from: potatoes, leek and peas

Parts of plant foods that help keep digestion working normally.

Learn about Fibre →

Milk and cheese provide calcium and protein. Potatoes and vegetables add carbohydrates and fibre. One portion does not show that an individual daily requirement has been met.

These notes refer to the ingredients in the base recipe. The amount on the plate depends on preparation, portion size and swaps. Variety across the week makes the difference.

Make it work for you.

Finely cut, tender pre-cooked broccoli can replace peas. Lactose-free dairy products still contain milk protein and remain a milk allergen.

Taking it slowly today?

Offer a less browned edge portion and a few soft potato slices. Leek need not be hidden; a small tasting portion is enough.

Keeping it safely

Promptly divide untouched leftovers into small, shallow containers and refrigerate at 5°C or below. Use within 24 hours. Reheat thoroughly in the centre as well as on the surface.
