Zwiebelrostbraten mit Röstzwiebeln & knusprigen Braterdäpfeln

Onion roast with fried onions & crispy roast potatoes

Strong, hearty, honest - that's what a real Viennese roast onion tastes like. I put Beiried in the pan, seared, refined with mustard, red wine and beef stock. On top: homemade fried onions that couldn't be better. And as a side dish? Fried potatoes - deep-fried in onion oil until crispy. A Sunday dish for every day - with instructions that even beginners can follow.

Preparation

Pat the meat dry and lightly score the edges. Coat one side with mustard and lightly flour the other. Season both sides with salt and pepper.

Fry well on both sides in hot clarified butter. Then keep warm in the oven at 80-90 °C or covered.

3. cook the onion sauce

Cut the onions into fine rings and fry in the drippings with fresh clarified butter for 10-15 minutes until golden brown. Stir in the tomato purée, dust with flour, stir, deglaze with red wine and add the stock. Reduce to a low heat and season with salt and pepper.

4. fried onions

Coat the finely sliced onion rings in flour and deep-fry in batches at 170-180 °C until golden brown and crispy. Drain on kitchen paper and season lightly with salt.

5. roast potatoes

Peel and dice the potatoes and blanch in lightly salted water for 3-4 minutes. Drain and deep-fry in onion oil. Drain on kitchen paper and season with salt.
