For the Liver:

2 tablespoons olive oil (or butter)

1 teaspoon garlic powder (optional)
1 teaspoon paprika (optional)
1/2 cup milk (optional, for soaking)
For the Onions:
2 large onions (sliced thinly)

1 teaspoon sugar (optional, for caramelizing)
Salt and pepper, to taste
1/4 cup beef broth (or water, if preferred)
Instructions
Prep the Beef Liver
The key to cooking beef liver perfectly lies in how you prepare and cook it.
Soak the Liver (optional but recommended): Beef liver has a strong, sometimes gamey flavor that can be toned down by soaking it in milk for about 30 minutes before cooking. This helps mellow the flavor and tenderizes the meat. After soaking, drain the liver and pat it dry with paper towels. This also helps the liver brown better during cooking.
Season the Liver: Season the liver slices on both sides with salt, pepper, garlic powder, and paprika (if using). The spices add a layer of flavor that complements the richness of the liver.
Caramelize the Onions
While the liver is soaking, or right before you start cooking, you can caramelize the onions. This adds a natural sweetness that balances the earthy flavor of the liver.
Heat the Pan: In a large skillet, heat 1 tablespoon of butter or olive oil over medium heat.
Cook the Onions: Add the sliced onions and season with a pinch of salt. Stir occasionally, allowing the onions to cook down and soften. This will take about 10–15 minutes. For a deeper, richer flavor, you can add a teaspoon of sugar to help the onions caramelize.
Add Liquid for Extra Flavor: Once the onions are golden brown and soft, pour in beef broth (or water) and a splash of balsamic vinegar for a touch of acidity and sweetness. Let the onions cook for an additional 5 minutes, allowing the liquid to reduce slightly. Once done, remove the onions from the pan and set them aside.
Cook the Beef Liver
Now it’s time to cook the beef liver.
Heat the Pan: In the same skillet (or a separate one if you prefer), heat the remaining 1 tablespoon of oil or butter over medium-high heat.
Cook the Liver: Add the liver slices to the hot pan in a single layer. Cook for about 2–3 minutes per side for medium-rare to medium doneness. You want the liver to brown on the outside but remain tender on the inside. If you overcook it, the liver can become tough and dry, so keep an eye on it.
Rest the Liver: Once the liver is cooked, remove it from the pan and let it rest for a couple of minutes.
Combine and Serve
Once both the liver and onions are cooked, it’s time to bring everything together.
Serve: Arrange the beef liver slices on a serving plate and top with the caramelized onions.
Garnish: For added flavor, you can garnish with freshly chopped parsley or thyme.
Optional Side Dish Ideas: Serve with mashed potatoes, sautéed spinach, rice, or a simple green salad. The richness of the liver pairs well with starchy or earthy sides.
Tips for the Perfect Beef Liver and Onions
Don’t Overcook the Liver: One of the most common mistakes when cooking beef liver is overcooking it. The liver should still be slightly pink in the center for optimal tenderness. If you prefer it more well-done, cook it for an additional minute, but be careful not to dry it out.
Rest the Liver: After cooking, let the liver rest for a few minutes. This helps retain its juices and keeps it tender.
Soak the Liver: Soaking liver in milk or a light brine can help remove some of the stronger flavors and tenderize the meat. It’s a step worth considering, especially if you’re new to eating liver.
Caramelize the Onions Well: The key to a great beef liver and onions dish is the onions. Caramelizing them slowly at medium-low heat allows them to develop a sweet, rich flavor that perfectly complements the savory liver.
Try Different Seasonings: While the basic seasoning of salt and pepper is perfect, you can get creative by adding fresh herbs, mustard, or even a splash of red wine while cooking the onions for more depth of flavor.
