Tender beef liver dredged in seasoned flour, pan-fried in butter, and served with sweet caramelized onions — it comes together in 25 minutes and is far more delicious than most people expect.
If you grew up eating this, it will take you straight back. If you never have, this is a good place to start.
Ingredients
- 1 pound beef liver (450g)
- 2 large onions, sliced
- ½ cup all-purpose flour (60g)
- 3 tablespoons butter (40g)
- 1 tablespoon olive oil (15ml)
- ½ teaspoon salt
- ¼ teaspoon black pepper
How to Make Liver and Onions
Step 1: Prepare the Liver
Slice the liver into even portions if not already cut. Pat dry with paper towels — removing surface moisture helps the flour coating stick and gives you a better sear.
Step 2: Dredge in Seasoned Flour
In a shallow bowl, mix together the flour, salt, and black pepper. Lightly coat each liver slice in the seasoned flour, shaking off any excess.
Step 3: Cook the Onions
Heat the butter and olive oil together in a large skillet over medium heat. Add the sliced onions and cook for 10–12 minutes, stirring occasionally, until softened and caramelized to a golden color. Remove the onions from the skillet and set aside.
Step 4: Cook the Liver
Place the floured liver slices into the same hot skillet. Cook for 2–3 minutes per side until browned on the outside but still tender inside. Do not overcook — liver continues to firm up as it rests, and a few minutes too long is the difference between tender and tough.
Step 5: Bring It Together
Return the caramelized onions to the skillet and warm everything together for about 1 minute. Serve immediately with mashed potatoes or buttered greens.
Recipe Notes
- Soak liver in milk first if desired. Soaking for 30 minutes before cooking draws out some of the stronger flavor and results in a milder, more approachable taste. This step is optional but recommended if you are sensitive to the strong flavor of liver.
- Do not overcook. This is the most important tip. Overcooked liver becomes tough and grainy. Pull it from the pan when it is just browned and still has a slight give when pressed.
- Pat the liver dry before dredging so the flour adheres properly and you get a better crust.
- Use both butter and oil. Butter adds flavor; oil raises the smoke point so the butter does not burn.
Storage
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in a skillet over low heat — avoid high heat which will dry the liver out quickly.

Frequently Asked Questions
Should I soak liver in milk before cooking?
Soaking beef liver in milk for 30 minutes before cooking is optional but widely recommended. It draws out some of the blood and reduces the strong, metallic flavor, making the liver noticeably milder. If you are new to cooking liver or sensitive to its taste, this step is worth doing.
How do I keep liver tender?
Cook it quickly over medium heat and keep a close eye on it. Liver only needs 2–3 minutes per side — overcooking is what makes it tough and grainy. Pull it from the pan while it still has a slight give and let it rest for a minute before serving.
Can I use chicken liver instead of beef liver?
Yes. Chicken liver works well and has a softer, milder flavor than beef liver. It cooks faster though — about 1–2 minutes per side — so reduce the cooking time accordingly.
Why do you dredge liver in flour?
The flour coating creates a light golden crust on the outside that adds texture and helps seal in moisture. It also thickens the pan juices slightly, which adds richness to the dish.
What does liver and onions taste like?
Beef liver has a rich, savory, slightly mineral flavor that is distinctly different from regular cuts of beef. The caramelized onions balance that intensity with their natural sweetness, and the flour crust adds a mild, buttery flavor. When cooked correctly it should be tender, not rubbery or bitter.
Is liver and onions healthy?
Beef liver is one of the most nutrient-dense foods available — it is high in protein, iron, vitamin B12, vitamin A, and folate. When cooked simply with flour, butter, and onions as in this recipe, it is a nutritious and satisfying meal.
