Beef Liver And Onions Recipe

This liver and onions recipe is super simple to make and while cooked calf liver can be an acquired taste, I show you how to take the bitter taste out of the liver pieces and top them with perfectly caramelized onions for an iron-rich entree.

Beef liver may be your first introduction to organ meats but did you know that turkey gravy also makes use of organs? Turkey gravy made with giblets is a classic Thanksgiving side dish.

📝 Ingredient notes:

• Beef liver - calves liver is preferable. Liver slices can be found in the frozen section in grocery stores.
• Milk -
• Onions - Vidalia onions or other yellow onion
• Flour - all-purpose flour
• Butter - salted butter is what I used in this recipe
• Olive oil - used to help raise the smoking point of the butter when frying

🔄 Substitutions

• Chicken liver can be used in place of beef veal liver. Chicken livers do not need to be sliced. They can be cooked whole.
• Season the dredging flour with salt, ground black pepper, garlic powder, and paprika. ¼ teaspoon of each.
• Instead of frying in butter and olive oil, bacon grease would make a delicious alternative.

🧅 How to make liver and onions

1. Start by rinsing the liver and soaking in milk. Soak the liver in milk for one hour in the refrigerator.
   
2. While the liver is soaking, start caramelized the onions.
   
3. Slice the onions in ¼ inch slices.
   
4. Heat 3 tablespoons butter to the point of foaming in a cast iron or large skillet.
   
5. Add the onions in a single layer and drop the heat to low.
6. Do not disturb the onions for 15 minutes.
   
7. Stir the onions and then every 10 minutes after until the onions are caramelized. This should take up to 45 minutes. Low and slow is the key.
   
8. Once the onions have caramelized transfer them to a clean plate and cover with foil to keep warm.
   
9. Remove the milk soaked liver from the milk bath and pat it dry with paper towels.
   
10. Dredge the beef liver in seasoned flour, coating all surfaces, pressing it into the flour.
    
11. Heat the remaining butter with a few tablespoons of olive oil to the point of almost smoking.
    
12. Gently lay the flour coated liver in the hot oil and quickly sear in the oil for no more than 3 minutes per side.
13. Remove from the frying pan and serve with the caramelized onions.

Sous Vide Liver And Onions

To keep from overcooking and toughening the liver, sous vide is the perfect cooking technique for tender liver and onions.

1. Start by rinsing the liver and soaking in milk. Soak the liver in milk for one hour in the refrigerator.
2. After soaking the liver, remove it from the milk bath and place it in a sous vide bag.
   
3. Heat the sous vide to 130 F . Use the water displacement method to press the air out of the bag and secure the bag to the edge of the cooing vesel.
4. Cook for 30 minutes. While the lover cooks, start carmalizing the onions.
5. Slice the onions in ¼ inch slices.
6. Heat 3 tablespoons of butter to the point of foaming in a cast iron skillet or heavy bottom pan.
7. Add the onions in a single layer and drop the heat to low.Do not disturb the onions for 15 minutes.
8. Stir the onions and then every 10 minutes after until the onions are caramelized. This should take up to 45 minutes. Low and slow is the key.
9. Once the onions have caramelized transfer them to a clean plate and cover with foil to keep warm.
10. Remove the liver and pat it dry with paper towels.
    
11. Dredge the beef liver in seasoned flour, coating all surfaces, pressing it into the flour.
12. Heat the remaining butter with a few tablespoons of olive oil to the point of almost smoking.
13. Gently lay the flour coated liver in the hot oil and quickly sear in the oil for no more than 1 minute per side.
    
14. Remove from the frying pan and serve with the caramelized onions.

💧Water Displacement vs. Vac and Seal

I have found that using the water displacement method works well for either a have found that the water displacement method is my preferred method of sealing the bag when there is a bone in the meat. There is less chance of a puncture from the bone with water displacement vs. vac and seal.

Water displacement also known as the Archimedes’ principle is when the pressure of the water forces the air out of the bag. 

To submerge using the water displacement method:

1. Place the meat in a heavy-duty, zip-top bag and close all but about 1 inch of the zip-top bag.
2. Submerge the bag in the water allowing the pressure of the water to force the air out.
3. Just as the water gets to the gap in the bag, close the bag.

If using a vac and seal bag, be sure to double seal the top and bottom seams because this will be a long cook. Look for a van and seal bag with a side gusset to help accommodate the larger piece of meat.
