In this article I show you the fast Potato Casserole Recipe. It comes from my first cookbook: Der Minutenkoch – schmeckt.schneller. I have optimised and refined the dish many times in recent years.

In addition to potatoes as the main ingredient, courgettes are also added to the casserole. With a little skill you can prepare it in less than 15 minutes. Then the oven does the work and you can dress up for dinner.

I wish you all the best and look forward to your comments at the end of this page.

2. Vegetarian Gratin and Side Dishes

You can tell by the shopping list This potato gratin is vegetarian and creates variety at the dining table.

I like to serve a colourful leaf salad with the potato gratin. So the creamy preparation with cream finds a refreshing addition.

Always wash the salad thoroughly, then spin dry and marinate with a simple vinegar-oil dressing. Tomatoes, radishes and other vegetables are an excellent accompaniment.

Preparation Time

20 Min.

Cook Time

40 Min.


2 pc clove of garlic
1 pc onion
0,4 l Cream (you may also use soy sauce)
1 pc vegetable broth cube
1 tsp Salt
6 pinch white pepper
4 pinch nutmeg
3 pinch Cayenne pepper
2 pinch curry (yellow Madras Curry gives a tasteful depth)
6-8 pc Potatoes (I use a waxy potato variety)
25 g butter (soft)
1-2 pc Zucchini
150 g grated Emmentaler (cheese is optional! also Gouda, blue cheese, Parmesan, Pecorino)


Preheat the oven to 200°C. Peel and chop the garlic and onions.

Put onion cubes and garlic cubes in a saucepan. Add the cream, vegetable stock cubes, salt, pepper, nutmeg, cayenne pepper and curry and bring to the boil. Mix the cream stand with a hand blender and leave to stand for 5 minutes.

Cut the courgettes into long, thin slices or plane them evenly. A thickness of 2 mm is ideal.

Peel the potatoes. Cut the peeled potatoes into 3 mm thick slices.

Spread a casserole dish with the butter.

Place a layer of potato slices in the buttered casserole dish in a fan shape, then a layer of courgettes. Finally, place a mixed layer of zucchini slices and potato slices in the oven dish.

Pour the cream stand through a sieve over the potato gratin and distribute the liquid by shaking lightly.

Put the potato gratin in the oven for 25-30 minutes. Reduce the oven temperature to 175°C. Then optionally sprinkle with the finely grated cheese. Cook the potato gratin for another 10-15 minutes.

Cooking test: Pierce the potato gratin with a meat fork without resistance, and the potato gratin is ready!

Remove the potato gratin from the oven, portion and serve.

The potato gratin is a fully-fledged main course and goes just as well as a side dish with roast meat and fish as with roast lamb or beef.
