Instructions
1. Prepare the liver
Rinse liver slices and remove any visible membrane.
Optional: Soak the liver pieces in milk for 20 to 30 minutes to reduce bitterness, then pat dry.
2. Prepare the onions
Heat butter or oil in a large skillet over medium heat.
Add sliced onions and a pinch of salt.
Cook, stirring occasionally, until soft and golden brown, about 12 to 15 minutes.
Remove onions and set aside.
3. Cook the liver
Season the liver with salt and pepper.
Optional: Lightly dredge each slice in flour.
In the same skillet, add butter or oil and heat over medium-high.

Return the onions to the skillet with the liver.
Heat together for 1 to 2 minutes.
Serve immediately.

Tips
Do not overcook the liver. It becomes tough and grainy if cooked too long.
Soaking in milk greatly improves the flavor for those sensitive to the liver’s intensity.
Use fresh liver if possible; it has a cleaner taste.
Cook the onions low and slow to achieve deep sweetness.
Add a splash of beef broth at the end for extra moisture.

Variations
Bacon Version: Fry chopped bacon before cooking the onions. Use the bacon fat for extra flavor.
Gravy Version: After cooking the liver, add 1 tablespoon flour and 1 cup beef broth to the pan to create a quick gravy.
Herbed Version: Add thyme or parsley to brighten the flavor.
Wine Version: Deglaze the pan with a splash of white wine after cooking the liver for a subtle acidity.
