Detailed Directions and Instructions
Soak the Liver
Place the liver slices in buttermilk and let them soak for at least 30 minutes, up to 2 hours. This process helps reduce bitterness and tenderizes the meat. If buttermilk isn’t available, you can use regular milk mixed with a splash of lemon juice or vinegar.
Prepare the Onions
While the liver is soaking, slice the onions into thin rings. In a large skillet, melt 2 tablespoons of butter along with 1 tablespoon of olive oil over medium heat. Add the sliced onions and cook, stirring occasionally, for 15–20 minutes until they are soft and golden. Add a little salt during cooking to aid in the caramelization process.
Drain and Dredge the Liver
Once the liver has soaked, remove the slices from the buttermilk and pat them dry using paper towels. In a shallow bowl, combine the flour, salt, black pepper, garlic powder, and paprika. Dredge each slice of liver in the flour mixture, shaking off any excess flour.
Cook the Liver
In a separate skillet, heat the remaining 2 tablespoons of butter with 1 tablespoon of olive oil over medium-high heat. Carefully add the liver slices to the pan, being cautious not to overcrowd them. Cook each side for about 3 minutes, flipping once, until they are browned on the outside but still slightly pink in the center. Avoid overcooking to keep the liver from becoming tough.
Combine and Serve
After the liver is cooked, reduce the heat and return the caramelized onions to the skillet. Allow them to cook together for an additional couple of minutes. If desired, add a splash of Worcestershire sauce for enhanced flavor. Serve the dish hot, garnished with fresh parsley if using, alongside mashed potatoes, rice, or buttered toast.
Notes
Soaking Time
For best results, remember that soaking the liver for longer (up to 2 hours) will help in flavor and texture improvement.
Onion Cooking
Make sure to stir the onions occasionally to promote even caramelization and prevent burning.
Cooking Temperature
Cooking the liver over medium-high heat ensures a nice sear while keeping the inside tender.
Serving Suggestions
This dish pairs well with hearty sides like mashed potatoes or rice, complementing the rich flavor of the liver.

Cook techniques
Soaking the Liver
Soaking liver slices in buttermilk or milk with a splash of acid helps to tenderize the meat and reduce bitterness. Aim for at least 30 minutes, but soaking for up to 2 hours is even better.
Caramelizing Onions
To bring out the natural sweetness, cook sliced onions low and slow in butter and oil, stirring occasionally until they become soft and golden. Adding a pinch of salt can assist with the caramelization process.
Dredging the Liver
Before cooking, pat the soaked liver dry and dredge it in a seasoned flour mixture. This creates a flavorful crust that enhances texture and taste.
Cooking the Liver
Cook liver slices in a hot skillet with butter and olive oil for about 3 minutes per side, ensuring they are browned outside while remaining slightly pink inside. Avoid overcrowding the pan for even cooking.
Combining Ingredients
After the liver is cooked, returning the caramelized onions to the skillet allows the flavors to meld. Adding a splash of Worcestershire sauce can enhance the dish’s overall flavor profile.
