Austrian speciality. - Viennese onion roast beef.
"From scratch", starting with the "Jus" = meat stock. Which is incredibly time consuming, talk about hours. So this needs to be pre-made.
You start with roasting this in the oven. (I apologize for the oven walls, but this thing gets used every day & often enough to roast a chicken or other meat ...)

After some time you add this.

Then it is transferred into a pot.

More ingredients added.

You top it up, and let it boil.

Until there is absolutely not more left than this.


If you want to store it for a bit and not use it on the next day, fill it into a jar as long as it is hot and close it immediately.
So let's continue.
Roastbeef is covered in mustard on one side and then seared.

Keep it warm and add shallots to the pan for roasting.

In another pan prepare your baked potatoes with some onion and thyme added.

Then add the meat stock to the roasted shallots & boil.

Put the roastbeef back into that pan.

Serve.
I guarantee that if the meat stock is self-made from the best ingredients & given all the necessary time this is going to be an explosion of flavors par excellence.
Kind regards,
