For the best results, source high-quality calves liver from a trusted butcher or Whole Foods. Look for onions with firm texture and no signs of sprouting. Use aged balsamic vinegar for a richer flavor profile. You can find Worcestershire sauce in most grocery stores, typically in the condiment section.

If you can't find calves liver, beef liver is an acceptable substitute, though it may be slightly firmer. For a dairy-free version, replace butter with olive oil or vegan butter. To reduce the gaminess of liver, soak it in milk or buttermilk for 30 minutes before cooking, then pat dry thoroughly.

Store leftover grilled liver in an airtight container in the refrigerator for up to 2 days. Reheat gently over low heat to prevent toughening. Caramelized onions can be made ahead and stored in the fridge for up to 5 days or frozen for longer storage. Keep fresh herbs wrapped in damp paper towels in the refrigerator.

Step-by-Step Instructions for Grilled Liver

Follow these detailed steps to achieve perfectly grilled liver with caramelized onions every time.

🔥 Step 1: Caramelize the Onions

Heat 2 tablespoons of the olive oil in a large skillet over medium-low heat. Add the 2 whole thinly sliced Yellow Onions and cook for 20-25 minutes, stirring occasionally, until they reach a deep golden brown and caramelized state. You’ll know they’re ready when they’re sweet and fragrant, and have developed a rich, dark color.

Once caramelized, remove the onions from heat and set aside. They’ll add a sweet contrast to the savory liver.

👨‍🍳 Step 2: Prepare the Liver Marinade

In a bowl, whisk together 4 cloves minced Garlic Cloves, 2 tablespoons chopped Fresh Thyme, 2 tablespoons Balsamic Vinegar, 1 tablespoon Worcestershire Sauce, 1 teaspoon Salt, and 0.5 teaspoon Black Pepper. This marinade will infuse the liver with complex flavors.

Add the 1.5 lb sliced Calves Liver to the marinade, ensuring they’re fully coated. Cover and refrigerate for at least 30 minutes, or up to 2 hours for more intense flavor.

🔥 Step 3: Grill the Liver

Preheat your grill to medium-high heat. Remove the liver from the marinade, letting any excess drip off. Brush the grill grates with the remaining 2 tablespoons olive oil to prevent sticking.

Grill the liver slices for 3-4 minutes per side, or until they reach your desired level of doneness. For medium-rare, the internal temperature should be 145°F when measured with a meat thermometer. The liver should feel firm but yielding to the touch.

🥘 Step 4: Finish with Butter and Serve

Once grilled, transfer the liver to a plate and top with 2 tablespoons unsalted Butter. The heat from the liver will melt the butter, creating a rich sauce.

Serve the grilled liver with the caramelized onions spooned over the top. Garnish with 0.25 cup chopped Fresh Parsley and serve with 4 Lemon Wedges on the side. The citrus will cut through the richness of the dish.

To take your grilled liver recipe to the next level, consider adding some caramelized onions to the mix 🍠. It’s a game-changer! The sweetness of the onions pairs perfectly with the savory flavor of the liver. Here’s how you can make it happen.

🔪 Preparing the Liver

Start by slicing the liver into thin strips, about 1/4 inch thick. You can use either beef or chicken liver, whichever you prefer. Make sure to remove any connective tissue or membranes to ensure tender bites.

🥘 Marinating the Liver

In a bowl, whisk together olive oil, minced garlic, salt, and your choice of herbs (such as thyme or rosemary). Add the sliced liver to the marinade and let it sit for at least 30 minutes, or up to 2 hours in the refrigerator.

🔥 Grilling the Liver

Preheat your grill to medium-high heat. Remove the liver from the marinade, letting any excess liquid drip off. Grill the liver for 3-4 minutes per side, or until it reaches your desired level of doneness. For a nice char, make sure the grill is hot before adding the liver.

While the liver is grilling, cook the onions in a pan with some olive oil over low heat, stirring occasionally, until they’re softened and caramelized. This will take about 20-25 minutes ⏰. Serve the grilled liver with the caramelized onions on top, and enjoy! 💡

• For an extra burst of flavor, add some balsamic vinegar to the caramelized onions.
• If you prefer a crisper texture, you can coat the liver with a mixture of breadcrumbs and parmesan cheese before grilling.

By following these simple steps, you’ll be able to create a mouth-watering grilled liver recipe that’s sure to impress your friends and family 🎉.

Tips & Tricks for Perfect Grilled Liver

These expert tips will help you achieve tender, flavorful grilled liver with beautifully caramelized onions every time.

Temperature Control: For optimal results, make sure your grill is preheated to medium-high heat. Use a thermometer to check the internal temperature of the liver, aiming for 145°F for medium-rare. Letting the liver rest for a few minutes after grilling allows the juices to redistribute, ensuring a tender final product.

Onion Caramelization: To achieve perfectly caramelized onions, cook them slowly over medium-low heat for 20-25 minutes, stirring occasionally. This slow cooking process breaks down the onions’ natural sugars, creating a deep, rich flavor that complements the grilled liver beautifully.

Liver Preparation: When preparing the liver for grilling, ensure that you slice it into uniform thickness to promote even cooking. Marinating the liver for at least 30 minutes helps to tenderize it and infuse it with flavor. Don’t over-marinate, as this can make the liver too soft.

Grilling Technique: Brush the grill grates with olive oil before grilling to prevent the liver from sticking. Grill the liver slices for 3-4 minutes per side, or until they reach your desired level of doneness. Using a gentle touch when flipping the liver helps to prevent it from breaking apart.
