Instructions: How to Cook Beef Liver and Onions

Step 1: Prepare the Liver

Soak the Liver in Milk:
- Place the thinly sliced 500g of beef liver in a shallow dish and pour enough milk over the liver to cover it completely. Let it soak for at least 30 minutes to an hour. This step helps to mellow out the strong flavor and reduce bitterness.
Pat Dry the Liver:
- After soaking, remove the liver from the milk and pat it dry with paper towels.
Season the Flour:
- In a shallow dish, mix 1/2 cup of all-purpose flour with 1 teaspoon of salt, 1/2 teaspoon of black pepper, and 1 teaspoon of paprika (if using).
Dredge the Liver:
- Dredge each slice of liver in the seasoned flour, shaking off any excess. This will create a light crust when fried.

Step 2: Cook the Onions

Caramelize the Onions:
- In a large skillet, heat 2 tablespoons of vegetable oil over medium heat. Add the 2 large, thinly sliced onions and cook, stirring occasionally, for about 10-15 minutes, or until the onions are soft and caramelized.
Remove Onions from the Pan:
- Once caramelized, remove the onions from the skillet and set them aside on a plate.

Step 3: Cook the Liver

Fry the Liver:
- In the same skillet, melt 2 tablespoons of butter over medium heat. Add the dredged liver slices to the skillet and cook for about 2-3 minutes per side, or until browned and cooked through. Be careful not to overcook the liver, as it can become tough.
Remove Liver from the Pan:
- Once cooked, remove the liver slices from the skillet and set them aside on a plate with the onions.

Step 4: Make the Sauce

Deglaze the Pan:
- With the skillet still on medium heat, add 1/2 cup of beef broth or water to the pan. Use a wooden spoon to scrape up any browned bits from the bottom of the pan. These bits add flavor to the sauce.
Simmer the Sauce:
- Let the sauce simmer for 2-3 minutes, or until slightly reduced. If you prefer a thicker sauce, you can add a small amount of flour or cornstarch slurry (1 teaspoon of flour or cornstarch mixed with 1 tablespoon of water) to thicken it.
Return the Liver and Onions to the Pan:
- Add the cooked liver and onions back to the skillet with the sauce. Stir to coat the liver and onions with the sauce and heat through for another minute or two.

Step 5: Serve the Dish

Garnish and Serve:
- Transfer the liver and onions to a serving dish, spooning the sauce over the top. Garnish with chopped fresh parsley if desired. Serve hot with your choice of sides, such as mashed potatoes, rice, or steamed vegetables.

Cook’s Notes & Tips

Liver Doneness: Be careful not to overcook the liver, as it can quickly become tough. Cook just until it’s browned on the outside and slightly pink on the inside for the best texture.
Onion Caramelization: The key to sweet, flavorful onions is slow cooking. Don’t rush this step, as it adds depth to the dish.
Variations: You can add a splash of balsamic vinegar or Worcestershire sauce to the sauce for extra flavor.
