Step 1: Prepare the Liver
If desired, soak the liver in milk for 30–60 minutes. Drain and pat dry thoroughly with paper towels.
Step 2: Season the Flour
In a shallow bowl, combine the flour, salt, black pepper, garlic powder, and paprika.
Lightly dredge each slice of liver in the seasoned flour, shaking off any excess.
Step 3: Caramelize the Onions
Heat 2 tablespoons of butter and the olive oil in a large skillet over medium heat.
Add the sliced onions and cook for 12–15 minutes, stirring occasionally, until soft, golden, and caramelized.
Transfer the onions to a plate and keep warm.
Step 4: Cook the Liver
Add the remaining 2 tablespoons of butter to the skillet.
Place the liver slices in a single layer and cook for 2–3 minutes per side. Avoid overcooking, as liver becomes tough when cooked too long.
Step 5: Finish the Dish
Return the onions to the skillet.
If using, pour in the beef broth and Worcestershire sauce. Simmer for 2–3 minutes, allowing the flavors to blend and create a light sauce.
Step 6: Serve
Transfer to a serving platter and garnish with chopped fresh parsley.
Serve immediately while hot.

Tips for the Best Beef Liver and Onions
- Soaking the liver in milk helps reduce bitterness and creates a milder flavor.
- Don’t overcrowd the pan; cook the liver in batches if necessary.
- Cook just until the center is slightly pink for the most tender texture.
- Sweet onions, such as Vidalia, add extra flavor when caramelized.
- Store leftovers in an airtight container in the refrigerator for up to 2 days and reheat gently to avoid overcooking.
