Step 1

Slice mushrooms into thirds (lengthways) and place them into the air fryer basket. Spray with extra virgin olive oil and season with salt, pepper, and garlic powder. Then find room in the air fryer basket for some fresh rosemary and some peeled garlic cloves.

Step 2

Air fry for 9 minutes at 180c/360f and you will have a wonderful garlic and rosemary aroma in your kitchen.

Step 3

Discard the rosemary and remove the mushrooms and load into a bowl that you have added almost melted butter to. Then make sure the mushrooms and garlic are well coated in the butter. Then load into the fridge for tomorrow.

Step 4

Place your fillet steak on a chopping board, score and then add extra virgin olive oil, salt, pepper, thyme, and parsley.

Step 5

Air fry your steak for 5 minutes at 180c/360f, turn over and then do another 5 minutes on the same temp on the other side.

Step 6

Allow the fillet to rest until cool, then get rid of any excess juices and wrap in foil and fridge overnight.

Step 7

The next day allow the fillet, the pate, the mushrooms, and the puff pastry to go to room temperature.

Step 8

Roll out your pastry and spread on a layer of your pate. Then add a layer of mushrooms. Making sure you have enough mushrooms and pate for the top layer.

Step 9

Then add your beef over the pate and mushrooms.

Step 10

Next repeat step #8 again for your pastry layer that is going on top. Though note, you don’t need the pastry as big for the top section.

Step 11

Then place the top of the pastry over the beef wellington.

Step 12

Now add a layer of egg wash so that the pastry top and bottom will stick together and then tightly seal up the pastry.

Step 13

Turn over the beef wellington and now use scissors or a knife to do two cuts in the top for the wellington to breathe.

Step 14

Then add a layer of egg wash before placing in the air fryer basket.

Step 15

Air fry for 50 minutes at 180c/360f for a medium rare or 60 minutes for a medium to well.

Step 16

Allow to rest for 5 minutes (note it carries on cooking then) and then slice and serve.
