About This Recipe

Zwiebelrostbraten is one of Vienna's most beloved traditional dishes — a thick sirloin steak, sautéed and rested in a rich beef jus, crowned with a towering pile of crispy fried onion rings. It's found at every Viennese Gasthof (traditional restaurant) and represents the hearty, satisfying character of Austrian meat cookery. The sweet-savory fried onions are the soul of the dish.

Ingredients

Serves 4

  • 4 piecesbeef sirloin steaks (200g each)
  • 1 kgonions, two-thirds sliced into thin rings, one-third finely chopped
  • 1 cupall-purpose flour (for onion rings)
  • 1 cupbeef stock
  • 1/2 cupred wine
  • 4 tbspbutter
  • 2 cupsoil for frying
  • 1 tspsalt
  • 1/2 tspblack pepper

Instructions

  1. 1

    Fry the onion rings

    Separate onion rings, toss in flour, shake off excess. Fry in hot oil in batches at 180°C until golden and very crispy. Drain and season with salt. Keep warm.

  2. 2

    Season and cook the steaks

    Score the fat rim of each steak. Season generously. Sear in butter over high heat for 2–3 minutes per side for medium-rare. Remove and rest.

  3. 3

    Make the jus

    Add finely chopped onion to the same pan. Cook until soft. Add red wine, scraping up the browned bits. Add beef stock and simmer 5 minutes until slightly reduced.

  4. 4

    Serve

    Place steak in a shallow bowl. Ladle jus over and around. Top with a generous mountain of crispy onion rings.

Pro Tips

  • The onion rings must be very crispy — wet rings destroy the dish.

  • Scoring the fat prevents the steak from curling in the pan.

  • Rest the steak properly — 5 minutes minimum.

Variations

  • Add mushrooms to the jus

  • Serve with Viennese potato salad (in a warm vinegar dressing)

  • Make with pork instead of beef

Storage

Best eaten immediately. Leftovers can be refrigerated 2 days.

History & Origin

Zwiebelrostbraten has been a staple of Vienna's Gasthaus culture since the 19th century. 'Rostbraten' refers to the grill rack (Rost) on which the beef was traditionally cooked, and 'Zwiebel' (onion) describes the defining topping.

Frequently Asked Questions

How do I keep onion rings crispy?

Fry at high temperature until properly golden, drain well, and serve immediately. Keeping them warm in a low oven (80°C) for up to 15 minutes maintains crispiness.

What cut of beef?

Sirloin (Rostbraten in Austrian German) is traditional. Ribeye also works beautifully.
