Pour milk in shallow bowl.
Gently rinse liver slices and place in a milk bowl.
Soak for 30 minutes.
Combine the flour, onion powder, garlic powder, salt and pepper in a shallow dish. Whisk to combine. Set aside.
Melt 1 tablespoons of butter over medium heat in a large skillet.
Add onion to skillet and saute them in butter until soft
Remove onions to a separate dish and set aside.
Add remaining butter to skillet and increase temperature to medium high.
Drain liver and dredge both sides of each slice in the prepared flour mixture.
Place dredged liver in the skillet.
Cook until brown on the bottom. Turn and cook on the other side until browned.
Reduce temperature to medium and place sauteed onions on each slice.
Cook a little longer as desired. Be careful to not overcook. I like my liver just so all the pink inside is gone.
