How to Cook Beef Liver Perfectly: Simple Pan-Seared Method

Beef Liver is both a nutritious and flavorful food that deserves a special place in our cooking. Whether it comes from beef, veal, lamb, or poultry, each type of liver has its own unique characteristics, but all share exceptional nutritional richness.

Liver, especially beef liver, is one of the richest sources of heme iron, which is easily absorbed by the body. This is why it’s often recommended for people suffering from anemia or iron deficiency. Beyond iron, it’s also an excellent source of B vitamins, particularly B12, as well as vitamin A, copper, and zinc.

In this guide, we’ll show you how to prepare and cook liver in a simple and delicious way, to fully appreciate its flavor while benefiting from its nutritional qualities. Although we’ll focus on beef liver, the techniques presented can be adapted to other types of liver, such as veal liver, known for its more tender texture and delicate flavor.

Ingredients For The Best Beef Liver Recipe

Main Ingredient

• 1 pound (500g) of beef liver (choose quality liver, ideally organic and from grass-fed animals)

Cooking Fat

• 2 tablespoons of extra virgin olive oil (or clarified butter for a richer flavor)

Basic Seasonings

• Sea salt (adjust to your taste)
• Freshly ground black pepper

Optional Ingredients

• 2 medium onions, thinly sliced (perfect for the classic « liver and onions » preparation)
• 2 garlic cloves, crushed
• A few sprigs of fresh thyme or 1 teaspoon of dried thyme
• 1 bay leaf
• Fresh chopped parsley for garnish
• 3 tablespoons of flour (for lightly coating the liver if you want a crispier texture)
• 1 cup (250ml) of milk (for soaking, to soften the liver’s flavor)
• Or 2 cups (500ml) of water with 2 tablespoons of apple cider vinegar (alternative to milk soaking)

Preparing the Liver

Cleaning

1. Unwrap the liver and gently rinse it under cold water.
2. Using a sharp knife, carefully remove any visible membranes and blood vessels. This step is crucial to avoid bitterness and improve the final texture.
3. Pat the liver dry with paper towels to ensure perfect drying.

Cutting

1. Place the liver on a clean cutting board.
2. Cut it into slices of uniform thickness, ideally between 1/2 and 3/4 inch (1-1.5 cm). This thickness is optimal for allowing nice exterior browning while keeping the center tender.
3. For beef liver, which can be firmer, slightly thinner slices (around 1/2 inch or 1 cm) are sometimes preferable.

Tenderizing (optional but recommended)

1. Place the liver slices in a bowl containing cold milk or vinegar water.
2. Let soak for 30 minutes to 2 hours in the refrigerator. This process helps reduce the natural bitterness of the liver and softens its flavor.
3. After soaking, remove the slices and thoroughly dry them again with paper towels.

Seasoning

1. Arrange the liver slices on a flat surface.
2. Sprinkle generously with salt and pepper on both sides.
3. If you opt for flour coating, lightly dredge each slice in flour, shaking off any excess. This thin layer will help form a slight golden crust while sealing the juices inside.

Cooking Methods

Pan-Searing (recommended method)

1. Choose a non-stick pan large enough to accommodate the slices without crowding them.
2. Preheat the pan over medium-high heat until it’s hot.
3. Add olive oil or clarified butter and heat until it shimmers slightly.
4. Carefully place the liver slices in the pan, making sure not to crowd them (cook in batches if necessary).
5. Sear for about 1-2 minutes on each side for beef liver. This quick high-temperature searing caramelizes the exterior while preserving the tender interior.
6. Then reduce the heat to medium and continue cooking for another 1-2 minutes depending on thickness and desired doneness.
7. For optimal texture, the liver should be pink in the center (about 145-150°F or 62-65°C internal temperature) but should not release blood when gently pressed.
8. If you prefer a gentler cooking method, you can cover the pan with a lid during the second part of cooking, which will allow the liver to steam and remain particularly tender.

Variation: Liver and Onions

1. Before cooking the liver, sauté the sliced onions in the same pan with a little olive oil or butter.
2. Cook them over medium heat for 8-10 minutes until they are tender and caramelized.
3. Remove the onions and keep them warm.
4. Cook the liver in the same pan using the method described above.
5. Serve the liver with the caramelized onions on top or alongside.

Variation: Veal Liver in a Pan

Veal liver is generally more delicate and requires even briefer cooking. Allow about 45 seconds to 1 minute on each side over high heat, then 30 seconds to 1 minute over medium heat. The center should remain pink and tender.

Other Cooking Methods

• Grilled: Preheat the grill to medium-high temperature. Lightly brush the liver with oil and grill 1-2 minutes on each side.
• Braised: Ideal for thicker pieces. After searing the liver, add some broth, wine, or sauce and simmer covered over low heat for 15-20 minutes.
• In pâté or terrine: Liver can be minced and mixed with other meats, spices, and aromatics to create flavorful terrines or pâtés.

Tips for Perfect Liver

• Never overcrowd the pan. The liver needs space to sear properly without sitting in its own juices.
• Use a non-stick pan with a good thick bottom for even heat distribution.
• The key to successful liver is quick cooking. Overcooked liver becomes grainy and develops a pronounced bitterness.
• Remove the liver from the pan as soon as it’s cooked, as it will continue to cook slightly with the residual heat.
• Let the liver rest for 1-2 minutes before serving to allow the juices to redistribute.
• To test doneness, gently press on the liver with the back of a fork: it should be firm but slightly elastic.

What to Serve with Liver

Liver pairs particularly well with:

• Buttermilk Mashed Potatoes
• Buttery Garlic Rice
• Ultimate French Fry Seasoning
• Cheesy Rice

For a balanced meal, accompany your liver with a starch and green vegetables, as well as fruit for dessert to complete the vitamin and mineral intake.

Important Notes

Liver Quality

The quality of the liver is paramount for a successful taste experience. Choose liver from controlled sources, ideally organic and from free-range animals fed naturally. Quality liver has a uniform color, without spots or discolored areas.

Storage

• Fresh liver should be consumed within 1-2 days of purchase.
• Store it in the refrigerator, in its original packaging or wrapped in food paper.
• If you don’t plan to consume it quickly, liver can be frozen for up to 2-3 months. Wrap it carefully in plastic wrap and then in a freezer bag to prevent freezer burn.
