- 2 tablespoons butter
For the Onions
- 2 large yellow onions, thinly sliced
- 2 tablespoons butter
- 1 teaspoon brown sugar, optional

How to Make Liver and Onions
1. Prepare the Liver
Remove the liver from its packaging and pat it thoroughly dry with paper towels.
If the liver has a tough membrane or large connective pieces, trim them away.
For a milder flavor, place the liver in milk for 20–30 minutes before cooking. Drain and pat completely dry afterward.
This soaking step is optional.
2. Prepare the Onions
Heat a large skillet over medium heat.
Add 2 tablespoons of butter.
Add the sliced onions and sprinkle with salt and black pepper.
Cook for approximately 10–15 minutes, stirring occasionally.
The onions should become soft, golden, and lightly caramelized.
If desired, add the brown sugar during the final few minutes to encourage deeper caramelization.
Transfer the onions to a plate and keep them warm.
3. Season the Liver
In a shallow bowl, combine:
- Flour
- Salt
- Black pepper
- Garlic powder
- Paprika
Lightly coat each piece of liver in the seasoned flour.
Shake off the excess.
You want a thin coating rather than a thick layer.
4. Cook the Liver
Return the skillet to medium-high heat.
Add the vegetable oil and butter.
Once hot, carefully add the liver pieces in a single layer.
Don’t overcrowd the pan. Cook in batches if necessary.
Cook for approximately 2–3 minutes per side, depending on thickness.
The outside should become nicely browned while the inside remains tender.
For food safety, use a food thermometer and cook beef liver to 160°F (71°C) internally.
Avoid overcooking because liver can quickly become dry and tough.
5. Combine the Liver and Onions
Return the caramelized onions to the skillet.
Pour in the beef broth.
Gently stir everything together.
Allow the mixture to simmer for approximately 2–3 minutes so the flavors combine.
Optional: Make a Quick Gravy
For a richer version, remove the liver and onions from the skillet and keep them warm.
Add 1 tablespoon butter to the pan.
Sprinkle in 1 tablespoon flour and whisk for about 30 seconds.
Slowly pour in the beef broth while whisking continuously.
Add Worcestershire sauce.
Simmer for approximately 3–5 minutes, until the gravy thickens.
Return the liver and onions to the pan and spoon the gravy over everything.
Finish with freshly chopped parsley.

Tips for Tender Liver
Don’t slice it too thick
Thin or moderately thin slices cook quickly and are less likely to become tough.
Don’t overcrowd the skillet
Crowding lowers the pan temperature and prevents proper browning.
Don’t overcook it
Liver can go from tender to chewy very quickly.
Caramelize the onions slowly
Allowing the onions time to soften and brown brings out their natural sweetness.
Use fresh liver
Fresh, good-quality liver generally has a better texture and flavor than liver that has been stored for a long time.
Variations
Chicken Liver and Onions
Replace beef liver with chicken livers. They cook faster, so watch them carefully and use a thermometer to verify safe doneness.
Bacon Liver and Onions
Cook 4–6 slices of bacon until crisp. Remove the bacon and use some of the rendered fat to cook the onions and liver.
Crumble the bacon over the finished dish.
Mushroom Liver and Onions
Add 8 ounces of sliced mushrooms to the onions and cook until golden before adding the liver.
Southern-Style Liver and Gravy
Prepare the liver with seasoned flour and serve it with a generous amount of onion gravy over mashed potatoes.
Storage
Allow leftovers to cool promptly and refrigerate them in an airtight container.
Use within 3–4 days.
Reheat gently in a skillet over low to medium heat with a small splash of broth.
Avoid prolonged reheating because the liver can become tough.
