Soak the Römertopf for at least 10 minutes. You can also prepare the dish in a baking dish or a roaster, etc.
Slice the onions thinly. Season the meat with paprika, pepper and salt. Layer the onions and meat alternately in the saucepan, finally a thick layer of onions (they will be deliciously crispy).
Fill up with water / wine and put in the oven at 200 degrees (top / bottom heat) for 1.5-2 hours (the cooking time depends on the thickness of the pieces of meat and whether a Roman pot or casserole dish is used).
Mashed potatoes go just as well with it as baguette.
