in the grated onion evenly.
Transfer the meat mixture to a greased loaf pan or casserole dish, press down firmly, and smooth the surface. Use a knife to make a shallow, lengthwise indentation in the surface.
Bake in a preheated oven at 180°C (350°F) for about 60–75 minutes, or until a golden-brown crust has formed.
Let it rest briefly before slicing. Serve warm with sweet mustard, a pretzel, and potato salad, or cold in a roll. Enjoy!
