Place liver slices in a bowl and cover with milk. Let soak for 30–60 minutes to remove any bitterness and tenderize.
Prepare the Onions:
Heat 1–2 tablespoons of oil or butter in a skillet over medium heat.
Add sliced onions and sauté until golden brown and caramelized, about 10–15 minutes. Remove and set aside.
Coat the Liver:
Drain liver slices from milk and pat dry.
Season with salt and pepper, then lightly coat with flour.
Cook the Liver:
Heat remaining oil or butter in the skillet over medium-high heat.
Fry liver slices for 2–3 minutes per side until browned on the outside but still slightly pink inside (overcooking makes liver tough).
Combine and Serve:
Return onions to the skillet and toss gently with the liver.
Serve hot with mashed potatoes, rice, or crusty bread.
