Hi, I am a German Chef and Food Photographer. The imparting of cooking knowledge is my great passion. Everyone can cook for himself and with this website I would like to contribute to its success. Cooking questions I answer you gladly at the end of the articles. Have fun and good luck!

Here I show you my Cauliflower Casserole recipe, which comes in Italian variant as a vegetarian lasagna.
Pork and Co are full of power, because we both eat cauliflower!
Did you know that the blossom vegetables are also called cauliflower, cheese cabbage, blossom cabbage, grape cabbage, minaret cabbage or Italian cabbage? Cauliflower is often cooked around the world. White cabbage is one of the top 10 most popular vegetables. Especially in Asia, cauliflower is in great demand. This is not without reason: the cabbage as a whole already looks like a fresh painting. The cabbage is easy to clean and ingeniously simple to prepare. The best thing is that the cabbage is so versatile. You can integrate it into many dishes or make it the protagonist of a dish. In the following I will show you my great recipe with a casserole variant that you may not yet know. So let’s go to the kitchen and just get started. Have fun with it!

1. Cauliflower in Lasagne – that’s possible!

The cauliflower is a stable vegetable and succeeds with the right cooking time – Aha, it depends! – to 100%.

2. What you should know about cauliflower

I have thought about the most common uses of cauliflower to write down for you… In unpleasant childhood memories, the cauliflower came cooked, “pardon”, overcooked on the table and had the firmness of liquid butter. No, we don’t want that! We treat the cabbage at eye level and don’t do this to it, please!
You can fry, bake, blanch, cook and even grill cauliflower.

3. This is how the Cauliflower Casserole is made vegetarian

Now I’ll give you some professional cooking tips to make it easier for you in the kitchen!

3.2 Chef’s tips to make the Casserole a success

Everything in turn…
  1. Prepare the béchamel sauce for the casserole first.
  2. I preheat the oven at 200° C circulating air heat.
  3. Then take care of the cauliflower. It is cut into florets according to my recipe and then coarsely grated. Therefore you should not exaggerate the cooking time.
  4. As a crispy addition, chopped walnuts are added to the casserole. Thus we extend our taste palette with the court around the variant “nutty sweetly”. You will like that 😉
  5. A finely grated good spicy cheese – finger away from sliced cheese! – covers our casserole before it goes into the oven.
Reduce the oven temperature to 175° C immediately after inserting the lasagne and bake until the pasta plates are soft.
Grated cauliflower reduces the cooking time by half!
To test the degree of cooking, I usually prick my casserole after 15 minutes with a wooden stick.

3.3 Chef Tips for Preparing the Béchamel Sauce

The exact preparation of the white sauce I show you below in Steps with many photos. Just so much for the ingredients in advance: My béchamel sauce consists of onions or shallots (finer in taste), bay leaf and peppercorns, butter, flour, dry white wine, milk, salt, pepper and nutmeg.
