Calf liver and onions is a classic dish that has been enjoyed for generations. It’s a staple in many cuisines, including American, European, and Middle Eastern cooking. The combination of tender liver and sweet, caramelized onions is a match made in heaven. However, cooking calf liver and onions can be a bit tricky, especially for those who are new to cooking. In this article, we’ll take you through a step-by-step guide on how to cook calf liver and onions to perfection.
Choosing the Right Ingredients
Before we dive into the cooking process, it’s essential to choose the right ingredients. Here are a few things to keep in mind:
Selecting the Best Calf Liver
When it comes to choosing calf liver, look for fresh, tender, and pale-colored liver. Avoid liver that has a strong odor or is dark in color, as it may be old or spoiled. You can find calf liver at most butcher shops or supermarkets.
Picking the Perfect Onions
For this recipe, you’ll want to use sweet onions, such as Vidalia or Maui onions. These onions are naturally sweet and will caramelize beautifully when cooked. Avoid using yellow or white onions, as they can be too pungent and overpowering.
Preparing the Ingredients
Now that you have your ingredients, it’s time to prepare them for cooking. Here’s what you need to do:
Preparing the Calf Liver
Rinse the calf liver under cold water and pat it dry with paper towels. Remove any connective tissue or membranes from the liver, as they can be tough and chewy. Cut the liver into thin slices, about 1/4 inch thick.
Preparing the Onions
Peel the onions and slice them into thin rings. You can use a mandoline or a sharp knife to get even, thin slices.
Cooking the Calf Liver and Onions
Now it’s time to cook the calf liver and onions. Here’s a step-by-step guide:
Cooking the Calf Liver
Heat a large skillet over medium-high heat. Add a tablespoon of oil, such as olive or vegetable oil, to the skillet. Once the oil is hot, add the sliced calf liver to the skillet. Cook the liver for 2-3 minutes on each side, or until it’s cooked to your desired level of doneness.
Cooking Times for Calf Liver
Here are some cooking times for calf liver:
| Cooking Time | Level of Doneness |
|---|---|
| 2-3 minutes per side | Rare |
| 4-5 minutes per side | Medium-rare |
| 6-7 minutes per side | Medium |
| 8-10 minutes per side | Well-done |
Cooking the Onions
While the liver is cooking, heat another large skillet over medium-low heat. Add a tablespoon of oil to the skillet, followed by the sliced onions. Cook the onions for 20-25 minutes, stirring occasionally, or until they’re caramelized and golden brown.
Tips for Caramelizing Onions
Here are a few tips for caramelizing onions:
- Use a low heat to prevent the onions from burning.
- Stir the onions occasionally to prevent them from sticking to the skillet.
- Don’t overcrowd the skillet, as this can prevent the onions from cooking evenly.
Assembling the Dish
Now that the calf liver and onions are cooked, it’s time to assemble the dish. Here’s what you need to do:
Serving the Calf Liver and Onions
Slice the cooked calf liver into thin strips. Serve the liver with the caramelized onions and your choice of sides, such as mashed potatoes, rice, or steamed vegetables.
Variations on the Recipe
Here are a few variations on the recipe:
Adding Aromatics
You can add aromatics, such as garlic, thyme, or rosemary, to the skillet with the onions for added flavor.
Using Different Types of Liver
You can use different types of liver, such as beef or pork liver, in place of calf liver.
Adding a Sauce
You can add a sauce, such as a red wine reduction or a creamy mushroom sauce, to the dish for added flavor.

What is the best way to prepare calf liver before cooking?
To prepare calf liver, start by rinsing it under cold water, then gently pat it dry with paper towels to remove excess moisture. Remove any connective tissue or membranes from the surface of the liver, as these can make it tough and chewy.
Next, slice the liver into thin strips or medallions, depending on your desired presentation. If you’re concerned about the liver being too strong-tasting, you can also soak it in milk or vinegar for about 30 minutes before cooking to help mellow out the flavor.
How do I prevent calf liver from becoming tough and chewy?
To prevent calf liver from becoming tough and chewy, it’s essential to cook it briefly over high heat. This helps to sear the outside quickly, locking in the juices and tenderness. Be careful not to overcook the liver, as this can cause it to become dry and tough.
Another key is to not overcrowd the pan, as this can lower the temperature and cause the liver to steam instead of sear. Cook the liver in batches if necessary, and make sure to let it rest for a few minutes before serving to allow the juices to redistribute.
What type of onions are best for cooking with calf liver?
For cooking with calf liver, it’s best to use sweet onions such as Vidalia or Maui onions. These onions are naturally sweet and mild, which complements the rich flavor of the liver. They’re also less likely to overpower the dish with a strong onion flavor.
You can also use yellow or white onions if you prefer a stronger onion flavor. However, be aware that these onions may caramelize more quickly than sweet onions, so keep an eye on them to prevent burning.
How do I caramelize onions to bring out their natural sweetness?
To caramelize onions, heat a couple of tablespoons of oil in a pan over medium-low heat. Add sliced onions and cook, stirring occasionally, for about 20-25 minutes or until they’re deep golden brown. It’s essential to cook the onions slowly and patiently, as this allows them to develop their natural sweetness.
As the onions cook, stir them occasionally to prevent burning. You can also add a pinch of salt to help bring out their natural sweetness. Once the onions are caramelized, you can add them to the pan with the calf liver and cook for a few more minutes to combine the flavors.
What is the best way to season calf liver and onions?
To season calf liver and onions, start with a simple seasoning of salt, pepper, and flour. Dredge the liver slices in flour to coat, shaking off excess, then season with salt and pepper. You can also add other seasonings such as garlic powder, paprika, or dried thyme to taste.
When cooking the onions, you can also add a pinch of salt to bring out their natural sweetness. Additionally, you can add a squeeze of fresh lemon juice or a splash of red wine vinegar to balance out the richness of the dish.
Can I cook calf liver and onions in a slow cooker?
While it’s possible to cook calf liver and onions in a slow cooker, it’s not the recommended method. Calf liver is best cooked briefly over high heat to preserve its tenderness and texture. Slow cooking can cause the liver to become tough and dry.
However, you can cook the onions in a slow cooker to caramelize them. Simply add sliced onions to the slow cooker with a couple of tablespoons of oil and cook on low for about 8-10 hours or until they’re deep golden brown. Then, add the cooked onions to the pan with the calf liver and cook for a few more minutes to combine the flavors.
How do I store leftover calf liver and onions?
To store leftover calf liver and onions, let the dish cool completely to room temperature. Then, transfer it to an airtight container and refrigerate for up to 3 days or freeze for up to 2 months.
When reheating the dish, make sure to heat it to an internal temperature of at least 165°F (74°C) to ensure food safety. You can reheat the dish in the pan or in the oven, adding a splash of broth or water if necessary to prevent drying out.
