Soak the roll in water for about 10 minutes, then squeeze out all the water. Peel and fine dice the onion, sauté until translucent and lightly browned, then put into a bowl.
1 yellow onion, 1 hard roll
Add ground meat, spices, chopped parsley, garlic, and egg to the bowl and knead until combined (best to use your hands, but you can also use a fork).
500 grams mixed ground meat, 1 egg, 1 teaspoon sea salt, 1 teaspoon German mustard, 1 teaspoon dried marjoram, 1 teaspoon paprika powder, 1 teaspoon chili powder, 3 Tablespoons fresh parsley, 3 garlic cloves
Add the drained roll to the meat mixture and knead until combined.
1 hard roll
Shape your Frikadellen patties and lay them onto a floured surface, so they won’t stick. Heat some oil in a pan or on a griddle over medium-high, then add in enough Frikadellen to cover the pan (see note about Test Frikadelle).
oil for frying
Fry for a few minutes without turning until thoroughly browned, turn and repeat, then reduce heat to medium low and continue frying for 10 more minutes or until cooked through. Transfer Frikadellen to a plate lined with paper towel to rest for a few minutes before serving (see note about Leftovers).
