Ingredients
-
1 lb (450g) beef liver, sliced into thin strips
-
2 large yellow onions, thinly sliced
-
1 ½ cups whole milk (for soaking)
-
½ cup all-purpose flour (for dredging)
-
½ teaspoon garlic powder
-
Salt and pepper, to taste
-
3 tablespoons butter
-
2 tablespoons olive oil
-
Optional garnish: fresh parsley or chopped green onions
Instructions
1. Preparation
Start by soaking the liver. Place the sliced beef liver in a bowl and cover it with milk. Let it soak for at least 30 minutes, or up to an hour if you have time. This step helps to mellow the strong metallic flavor of the liver and yields a more tender texture.
While the liver is soaking, peel and thinly slice the onions. Set them aside.
Once the soaking time is up, remove the liver slices from the milk and gently pat them dry with paper towels.
2. Caramelize the Onions
In a large skillet, heat 2 tablespoons of butter and 1 tablespoon of olive oil over medium heat. Add the sliced onions and cook slowly, stirring occasionally, until they become golden brown and caramelized—this will take about 10–12 minutes. You want them soft and sweet with a little bit of char on the edges. Remove from the skillet and set aside.
3. Dredge and Season the Liver
In a shallow bowl or plate, combine the flour, garlic powder, salt, and pepper. Dredge each slice of liver lightly in the flour mixture, shaking off any excess.
4. Cook the Liver
In the same skillet, add the remaining 1 tablespoon of butter and 1 tablespoon of olive oil over medium-high heat. Once the pan is hot, add the dredged liver slices in a single layer. Do not overcrowd the pan; you may need to work in batches.
Cook the liver for about 2–3 minutes per side, depending on thickness. The goal is to get a nice sear on the outside while keeping the inside tender and slightly pink. Overcooking can make the liver tough and dry.
5. Combine and Finish
Once all the liver slices are cooked, return the onions to the skillet. Stir gently to combine and heat everything through for about 1–2 minutes. Turn off the heat and let the dish rest for 5 minutes to allow the flavors to meld.
Serving Suggestions
Serve your beef liver and onions hot, with creamy mashed potatoes or buttery rice to soak up the savory juices. A side of steamed green beans or sautéed kale adds freshness and color to the plate.
For an extra kick, a dash of hot sauce or a squeeze of lemon juice can brighten up the flavors. And if you’re feeling fancy, top it off with a sprinkle of fresh parsley.
Beef Liver and Onions is more than just a meal—it’s a reminder of home, heritage, and the beauty of simple, nourishing cooking. Rich in iron and protein, liver is one of those ingredients that deserves a comeback in the modern kitchen. When paired with sweet caramelized onions and cooked just right, it turns into a dish that’s satisfying, wholesome, and surprisingly elegant.
So the next time you’re in the mood for something comforting, give this classic recipe a try. You might just discover (or rediscover) a family favorite that has stood the test of time.
