Cultural Background
The zwiebel rostbraten is a classic Swabian dish from the south of Germany. This southern German specialty is an integral part of the restaurant menus and is traditionally served with handmade spaetzle or fried potatoes. In the original Swabian version, tasty Maultaschen accompanied the delicious beef dish.

Ingredients & Substitutes
This dish has few ingredients and is easy to put together. Using high-quality ingredients is essential for achieving a outstanding dinner experience. Forget about spending hours in the kitchen. This meal does not need a lot of active working time!

Beef – the aroma and tenderness of this Swabian meat dish largely depend on the meat’s quality. Well-marbled meat guarantees a tasty and juicy dish. Best suited for zwiebelrostbraten are well-hung steaks or roast beef with a visible and not too small fat rim. If the meat is too lean, the onion steak dries out during preparation and tastes bland.
Onions – I usually use yellow onions as I love a stronger onion flavor. But you can use white onions or shallots if you prefer a milder flavor.
Beef Stock – a strong, flavorful beef stock is important to give this dish the perfect flavor. If you don´t want to use a convenience product, it is very easy to make your own dark gravy base, which works perfectly not only for this dish.
Red Wine – adds a wonderful, rich flavor to the sauce. But if you don´t want to incorporate wine into the recipe, you can simply omit it and substitute for more beef stock.
Seasoning – the seasonings for this dish are very simple. Salt, pepper, paprika powder, and mustard do the trick. I use regular paprika powder, not the smoked version.
Oil – a use neutral vegetable oil to sear the steaks in the pan.
Butter – frying the onions in butter gives them a wonderful flavor. If you prefer crispy onions, you can deep fry them in oil.

Instructions

Step 7: Bring the mixture to a boil, then pop the steaks back in. Cover the pan, let it simmer on low heat for 60-180 minutes (depending on your meat’s thickness), and watch the flavors meld together beautifully.
Step 8: Take the steaks out of the pan, making sure they stay warm. Optional: If you want a smoother sauce, blend it using an immersion or stand blender. But if you’re a fan of a chunkier gravy, feel free to skip this step.
Time to serve! Drizzle the scrumptious sauce over your steaks and pile on the remaining fried onions. Dig in and enjoy the compliments!

Tips
If you want to make rostbraten for your guests or a large family, prep your spaetzle the day before (or serve with french fries) and peel and slice the onions ahead of time. The time spent cooking will be greatly reduced as a result, allowing you more time to relax and enjoy your lecker meal and good company.
Kitchen Utensils
These are the kitchen tools you need to make this delicious beef dish:
- Cutting board
- Chef’s knife
- Large frying pan or skillet with a lid
- Spatula or tongs (for flipping steaks)
- Slotted spoon or spatula (for removing onions)
- Pastry brush (for brushing mustard onto steaks)
- Plate (for setting aside cooked onions and steaks)
- Immersion blender or stand blender (optional, for blending sauce)

Storage
To store Zwiebel Rostbraten properly, follow these steps:
- Allow the dish to cool: Let the cooked steaks and onion gravy cool to room temperature. Avoid leaving the dish out for more than two hours, as this can encourage bacterial growth.
- Separate components: It’s best to store the steaks and onion gravy separately. This prevents the steaks from becoming soggy and helps maintain their texture.
- Use airtight containers: Transfer the cooled steaks and onion gravy into separate airtight containers. Using airtight containers helps preserve the flavors and prevents the dish from drying out.
- Refrigerate or freeze: If you plan on eating the leftovers within 3-4 days, store the containers in the refrigerator. For longer storage, place the airtight containers in the freezer. Properly stored, frozen Zwiebelrostbraten can last up to 2-3 months.
When you’re ready to reheat and serve your dish, follow these guidelines:
- Thawing (if frozen): Move the frozen containers to the refrigerator and allow them to thaw overnight.
- Reheating the steaks: Preheat your oven to 350°F (175°C) and place the steaks on a baking sheet or oven-safe dish. Cover with aluminum foil to keep them moist and reheat for about 10-15 minutes, or until they reach your desired temperature.
- Reheating the onion gravy: Pour the gravy into a saucepan and reheat over low to medium heat, stirring occasionally until it’s warmed through.
- Serve: Place the reheated steaks on a plate, pour the warm onion gravy over them, and garnish with the fried onions. Guten Appetit!
How to Serve
Traditionally, Zwiebelrostbraten is served with spaetzle, French fries, kroketten, crispy fried potatoes, or a slice of freshly baked rye bread, or french fries and a tasty variety of German salads.
Some restaurants also serve this onion steak with Maultaschen, which are traditional Swabian-style ravioli.
What to drink with Zwiebel Rostbraten?
Swabian connoisseurs have been debating the same question for generations! Is rostbraten best enjoyed with a glass of wine or a cold beer? Opinions differ when it comes to the right drink, as a Swabian onion steak with beer or a Trolling wine tastes equally delicious.
