Equipment
- Large skillet or frying pan
- Mixing bowls
- Tongs or spatula
- Knife and cutting board
- Paper towels
Ingredients
- 1 lb beef liver, sliced into thin pieces
- 2 large onions, sliced into rings
- 2 tbsp butter (divided)
- 2 tbsp olive oil (divided)
- ½ cup all-purpose flour
- 1 tsp salt
- ½ tsp black pepper
- ½ tsp garlic powder
- ½ tsp paprika
- ½ cup milk (for soaking)
- Fresh parsley (for garnish, optional)
Ingredient Notes
- Liver: Choose fresh, high-quality beef liver with a deep reddish-brown color. Calf liver is milder in flavor and more tender.
- Soaking in Milk: Soaking the liver in milk for at least 30 minutes before cooking helps reduce bitterness and creates a smoother taste.
- Onions: Yellow or sweet onions work best for caramelizing.
- Butter & Oil Combo: Butter adds flavor while oil prevents burning during frying.
Instructions
- Prepare the Liver:
Rinse the beef liver slices under cold water and pat dry with paper towels. Place them in a bowl and pour milk over the top. Let soak for 30 minutes, then drain and pat dry again. - Caramelize the Onions:
In a large skillet, heat 1 tbsp butter and 1 tbsp olive oil over medium heat. Add sliced onions and cook slowly for 10–12 minutes, stirring often, until golden and soft. Remove onions and set aside. - Season and Coat the Liver:
In a shallow dish, mix flour, salt, pepper, garlic powder, and paprika. Lightly coat each liver slice in the seasoned flour mixture, shaking off any excess. - Cook the Liver:
Add the remaining butter and olive oil to the skillet over medium-high heat. Fry the liver slices for about 2–3 minutes per side, just until browned. Avoid overcooking — the liver should remain slightly pink inside to stay tender. - Combine and Serve:
Return the caramelized onions to the skillet, mixing them with the liver. Heat together for 1 minute, then garnish with chopped parsley before serving.

Tips
- Don’t overcook the liver — it can turn tough and grainy if cooked too long.
- For a richer flavor, deglaze the pan with a splash of beef broth or red wine after cooking.
- Add a pinch of thyme or rosemary to the onions for an aromatic twist.
- Pairs beautifully with mashed potatoes, steamed vegetables, or rice.
Variations
- Gravy Version: After cooking the liver, add 1 tbsp flour to the pan drippings and 1 cup beef broth to create a smooth onion gravy.
- Bacon & Liver: Fry a few slices of bacon, crumble them, and sprinkle on top before serving for a smoky flavor boost.
- Low-Carb Version: Skip the flour coating and season the liver directly with spices before pan-searing.
- Calf Liver: Substitute for a milder, more delicate taste.
