What to keep in mind.
5 tips from the recipe — small details that make a real difference to the final dish.
- 1For an authentic touch, use Bavarian Leberkäse, which is typically all pork.
- 2Don't rush the onions. Cooking them low and slow is key to developing a deep, sweet flavor.
- 3A runny yolk is traditional as it creates a delicious sauce that soaks into the bread and meat.
- 4If you can't find Kaiser rolls, pretzel buns or any sturdy, crusty roll will work well.
- 5Serve with a side of German potato salad (Kartoffelsalat), pickles (Gurken), or french fries (Pommes Frites) for a complete meal.

Add Cheese
Melt a slice of Emmentaler or Swiss cheese on top of the Leberkäse during the last minute of cooking.
Different MustardDifferent Mustard
If you prefer more of a kick, substitute the sweet mustard with a spicy brown or medium-hot German mustard (mittelscharfer Senf).
Add PicklesAdd Pickles
Add a few slices of dill or gherkin pickles inside the sandwich for a tangy crunch.
Skip the EggSkip the Egg
For a simpler version, you can omit the fried egg. The sandwich is still delicious with just the Leberkäse and onions.
Why this is on our healthy list.

With significant protein from both the Leberkäse and the egg, this sandwich supports muscle repair, growth, and helps keep you feeling full and satisfied.
Source of B Vitamins
Pork and eggs are excellent sources of B vitamins, particularly B12 and B6, which are crucial for energy metabolism, brain function, and the formation of red blood cells.
Provides Iron
The red meat in Leberkäse is a good source of heme iron, a form of iron that is easily absorbed by the body and is essential for preventing anemia and transporting oxygen in the blood.
Frequently asked questions
Leberkäse is a German meatloaf specialty. Despite its name, which translates to 'liver cheese', traditional Bavarian Leberkäse contains neither liver nor cheese. It's made from finely ground corned beef, pork, and bacon, baked into a loaf until it has a crispy brown crust.
