Add the milk and chopped bread to a bowl. Let it soak for 5-10 minutes.
In the meantime, add some butter to a pan and sauté the onion and garlic over medium heat until the onion is soft.
Now drain the milk and remove excess moisture from the bread using a fine-mesh strainer or nut milk bag. Add all ingredients, except for the vegetable oil, to a mixing bowl and thoroughly knead everything with your hands.
Roll the meat mixture into balls and flatten them with your hands.
Preheat the vegetable oil in a pan over medium-high heat. Then sear and cook the Frikadellen from both sides for around 15 minutes (7-8 minutes for each side) over medium heat until they are cooked through. Adjust the heat as needed so the Frikadellen don't burn. Enjoy!
