Ingredients
- 500 g (1 lb) beef liver: Fresh, tender beef liver, cleaned and sliced for optimal texture and rich flavor.
- 2–3 tbsp butter or oil: Used for sautéing, adds richness and prevents sticking during cooking.
- 2 large onions, thinly sliced: Provides natural sweetness and a delicate crunch once caramelized.
- 2–3 garlic cloves, minced: Offers a subtle aromatic depth and sharpness to the dish.
- 1 tsp paprika (optional): Adds a mild smoky warmth and enhances the color of the liver.
- Salt & freshly ground black pepper, to taste: Essential seasonings that highlight and balance the flavors.
- Optional: splash of balsamic vinegar or a squeeze of lemon: Adds bright acidity for a fresh finish and cuts through richness.
Instructions
- Prepare the Liver
-
Rinse the beef liver under cold water, then pat dry with paper towels to remove excess moisture. Optionally, soak the liver slices in milk for 30 minutes to help mellow its strong, sometimes bitter flavor. After soaking, drain and pat dry again to ensure they brown properly during cooking.
- Caramelize the Onions
-
Heat 1 to 2 tablespoons of butter or oil in a large skillet over medium heat. Add the thinly sliced onions and cook slowly, stirring occasionally for 10 to 12 minutes, until they become soft and golden brown. This slow caramelization process brings out their natural sugars, lending a sweet complexity to the dish. Add minced garlic and cook for an additional minute, then transfer the mixture to a plate and set aside.
- Cook the Liver
-
Return the skillet to the stove and add a bit more butter or oil to prevent sticking. Season the liver slices evenly with salt, freshly ground black pepper, and paprika if using. Place the liver in the skillet and cook for about 2 to 3 minutes per side, allowing the exterior to develop a nice brown crust while keeping the inside slightly pink for optimum tenderness. Avoid overcooking, which can cause the liver to toughen.
- Combine & Serve
-
Once the liver is cooked, return the caramelized onions to the skillet and gently toss to warm through with the liver. If desired, add a splash of balsamic vinegar or a squeeze of lemon juice to brighten and balance the richness. Serve immediately for best flavor and texture.
- Overcooking liver causes it to become tough and dry, so aim for medium doneness with a slightly pink center.
- Adding a splash of Worcestershire sauce or fresh herbs like thyme can elevate the depth of flavors.
- Soaking liver in milk before cooking helps reduce any strong, bitter notes for a milder taste.
Storage Tips
Store leftover liver and onions in an airtight container in the refrigerator for up to 2 days. Reheat gently on the stovetop or in the microwave to avoid drying out the liver.
Serving Suggestions
This dish pairs wonderfully with creamy mashed potatoes, steamed rice, or crusty bread to soak up the flavorful juices. For a balanced meal, serve alongside sautéed greens or roasted seasonal vegetables to add freshness and texture.
- Trim away any membranes or sinew from the liver slices to improve texture before cooking.
- Allow the skillet to be hot before adding liver to achieve a nice sear, which locks in juices.
- Use clarified butter for sautéing to prevent burning and deepen the buttery flavor.
