A Brief History
The pairing of liver and onions is a classic found in many cultures, from the British “liver and bacon” to the French “foie de veau à la lyonnaise.” Its origins are rooted in practicality and frugality. Liver, being an organ, was often one of the more affordable cuts of meat available. Onions, a sturdy and long-lasting vegetable, were a staple in pantries across the globe. The combination was a natural one: the strong, earthy flavor of the liver was perfectly balanced by the sharp, sweet, and caramelized notes of cooked onions. It became a staple of “meat and potatoes” dinners, especially during the early to mid-20th century, providing essential nutrients at a low cost. Today, it’s experiencing a resurgence as chefs and home cooks alike rediscover the beauty of whole-animal cooking and deeply satisfying, rustic flavors.

Instructions: The Method to the Magic
Step 1: Prepare the Liver (The Secret to Tenderness)
Liver can sometimes have a slightly bitter or metallic taste. To mitigate this and ensure tenderness, place the sliced liver in a bowl and cover with buttermilk (or milk). This step is optional but highly recommended. The lactic acid in the milk helps to tenderize the liver and mellow its flavor. Let it soak for 30 minutes while you prepare the other ingredients. After soaking, remove the liver, pat it extremely dry with paper towels. Moisture is the enemy of a good sear.
Step 2: The Low & Slow Onions
In a large, heavy-bottomed skillet (like cast iron), heat 2 tablespoons of butter and 1 tablespoon of olive oil over medium heat. Add the sliced onions and a pinch of salt. Cook, stirring occasionally, for 15-20 minutes, until they are soft, sticky, and a deep golden brown. This is the “low and slow” method for caramelized onions. Add the thyme sprigs for the last 5 minutes. Once caramelized, transfer half of the onions to a small bowl and leave the rest in the pan to form the base of your gravy.
Step 3: Build the Gravy Base
To the skillet with the remaining onions, increase the heat to medium-high. Pour in the wine (if using) and scrape up any browned bits from the bottom of the pan (this is called déglaçage and is full of flavor). Let the wine reduce by half, about 1-2 minutes. Pour in the beef stock and bring to a simmer. Let it cook until it reduces slightly and thickens, about 5 minutes. Turn off the heat and set the skillet aside. You’ll reheat it later.
Step 4: The Perfect Sear
Place the seasoned flour in a shallow dish. Dredge the dried liver slices in the flour, shaking off any excess. This thin coating will create a beautiful crust.
In a separate skillet (or wipe out your onion skillet if you don’t have another), heat the remaining 2 tablespoons of butter and 1 tablespoon of olive oil over medium-high heat until the butter stops foaming and just begins to brown.
Carefully place the liver slices in the hot pan in a single layer. Do not overcrowd the pan; cook in batches if necessary. The key to tender liver is a quick sear.
· For calf/chicken liver: Cook for just 1-2 minutes per side. The inside should still be slightly pink.
· For beef liver: Cook for 2-3 minutes per side. It’s best served slightly pink in the center as well; overcooking is what makes it tough and grainy.
Step 5: Assemble and Serve
Once the liver is cooked, place it on a serving platter. Reheat the onion gravy in the first skillet. Spoon the gravy and the reserved caramelized onions over the top of the fried liver. Garnish with fresh chopped parsley.
