Ingredients
- 1.5 pounds beef liver, sliced into ½-inch thick pieces
- 6 slices bacon, chopped
- 3 large yellow onions, thinly sliced
- 4 tablespoons butter, divided
- 3 cloves garlic, minced
- 1 cup beef broth
- ¼ cup balsamic vinegar
- 2 tablespoons fresh thyme leaves
- 1 tablespoon Dijon mustard
- ½ cup all-purpose flour
- 1 teaspoon salt, plus more to taste
- ½ teaspoon black pepper, plus more to taste
- Pinch of cayenne pepper
- 2 tablespoons olive oil
- Fresh parsley for garnish
- Fleur de sel for finishing
Instructions
- Pat the beef liver dry with paper towels and remove any visible connective tissue or membranes using a sharp knife. This is crucial for texture.
- Season the liver generously on both sides with salt, pepper, and cayenne pepper. Let it sit at room temperature for 10 minutes.
- In a small bowl, combine flour, 1 teaspoon salt, and ½ teaspoon black pepper. Lightly dredge each piece of liver in the flour mixture, shaking off excess.
- Cook the chopped bacon in a large skillet over medium heat until crispy, about 8-10 minutes. Transfer to a paper towel-lined plate, leaving 2 tablespoons of bacon fat in the pan.
- Add 2 tablespoons of butter to the bacon fat and increase heat to medium-high. Add the sliced onions and a pinch of salt.
- Cook the onions, stirring occasionally, until they’re deeply caramelized and golden brown, about 15-18 minutes. If they’re browning too quickly, reduce heat slightly. Transfer to a plate.
- Return the skillet to high heat and add olive oil. Once the oil is shimmering and very hot, carefully place the liver pieces in the pan in a single layer.
- Sear the liver for 2-3 minutes on the first side without moving it. You want a beautiful brown crust to develop.
- Flip each piece and sear for another 2-3 minutes on the second side. The liver should still be slightly pink in the center—do not overcook.
- Transfer the cooked liver to a clean plate and tent loosely with foil to keep warm.
- Reduce heat to medium and add the remaining 2 tablespoons of butter to the pan. Add minced garlic and cook for 30 seconds until fragrant.
- Pour in the beef broth and balsamic vinegar, scraping up any browned bits from the bottom of the pan with a wooden spoon.
- Add the fresh thyme and Dijon mustard, stirring to combine. Simmer for 3-4 minutes until the sauce reduces slightly and thickens.
- Return the caramelized onions to the pan and stir in the crispy bacon. Season the sauce with additional salt and pepper to taste.
- Return the liver to the pan and gently turn to coat in the sauce. Heat through for 1 minute, being careful not to overcook the liver further.
- Transfer the beef liver to a serving platter and pour the onion, bacon, and pan sauce over the top. Garnish with fresh parsley and a sprinkle of fleur de sel.
- Serve immediately while hot with your choice of sides such as creamy mashed potatoes, buttered egg noodles, or crusty bread to soak up the delicious sauce.
Pro Tips
Trimming Technique: Beef liver has thin membranes covering it that can become tough when cooked. Gently pull the membrane away and use a sharp knife to carefully remove it. This step makes a huge difference in texture.
Temperature Control: This is the most important step for tender beef liver. High heat for a quick sear creates a flavorful crust while keeping the interior tender and juicy. Medium-rare to rare is ideal—the internal temperature should reach about 130-135°F maximum.
Flour Dredging: A light coating of flour creates a delicate crust and helps thicken the pan sauce. Don’t skip this step, but do shake off excess flour so you don’t end up with a thick coating.
Caramelizing Onions: This takes time but is absolutely worth it. The slow cooking brings out the natural sugars and creates deep, complex flavor. If you’re short on time, you can skip this, but it really elevates the dish.
Bacon Quality: Use thick-cut, high-quality bacon for the best flavor. The rendered fat is liquid gold for this recipe and adds richness to the sauce.
Pan Selection: Use a stainless steel or cast iron skillet for this recipe. Non-stick pans won’t develop the proper crust needed for maximum flavor.
Sauce Customization: Add a splash of red wine, a tablespoon of soy sauce, or fresh sage for different flavor profiles. The basic technique remains the same.
Make-Ahead Options: You can prepare the caramelized onions and bacon up to one day ahead. Store separately and reheat gently before serving. Cook the liver just before serving for best results.
Leftovers: While beef liver is best served immediately, leftovers can be stored in an airtight container for up to two days. Reheat gently in a 300°F oven to avoid overcooking.
Wine Pairing: This dish pairs beautifully with Pinot Noir, Burgundy, or a lighter Bordeaux. The earthy flavors complement the rich liver perfectly.
Serving Suggestions: Creamy mashed potatoes, buttered egg noodles, wild rice, polenta, or roasted vegetables all make excellent sides.
