Sautéed Baby Beef Liver Recipe

Trim and slice

Rinse the baby beef liver under cold water and pat dry with paper towels. Trim away any visible membranes, connective tissue, or large blood vessels. Slice the liver into 1/4- to 1/2-inch thick slices against the grain for tender pieces. Pat the slices dry again.

Season and dredge

In a shallow dish, combine the flour, kosher salt, black pepper and paprika. Lightly season both sides of each liver slice with a pinch more salt and pepper if desired. Dredge each slice in the flour mixture, shaking off excess. Set dredged slices on a wire rack or plate while you heat the pan.

If using onions, peel and cut the onion into 1/4-inch half-moons. In a large skillet, heat 1 tablespoon olive oil (or vegetable oil) over medium heat. Add the sliced onions and a pinch of salt. Cook, stirring occasionally, until they begin to soften and turn translucent, about 6–8 minutes. If you want more caramelized onions, reduce heat to medium-low and continue cooking another 8–12 minutes, stirring occasionally; stir in 1/2 teaspoon brown sugar after they start to brown to encourage caramelization. Transfer onions to a bowl and keep warm.

If using bacon, lay the bacon slices in a cold skillet and place over medium heat. Cook slowly until fat renders and bacon is crisp or to desired doneness, about 8–10 minutes, turning occasionally. Remove bacon to a plate lined with paper towels, reserving the rendered bacon fat in the skillet. If bacon is very thin and renders quickly, reduce heat as needed so pieces don't burn.

Heat a large heavy skillet (cast iron or stainless) over medium-high heat. Add the vegetable oil and 1 tablespoon unsalted butter (or the reserved bacon fat if using bacon) and swirl to coat. The fat should be hot but not smoking—test by dropping a little flour from the dredged liver; it should sizzle immediately.

Arrange the floured liver slices in a single layer in the skillet without overcrowding; work in batches if necessary. Sear the liver for 1½ to 2 minutes per side for medium-rare to medium (internal temperature about 145°F/63°C). The exterior should be golden-brown and slightly crisp while the interior remains pink — avoid overcooking, which makes liver tough and grainy. Adjust time for thinner or thicker slices.

As you finish each batch, transfer cooked slices to a warm plate and tent loosely with foil to keep warm. Add another small pat of butter to the pan between batches if needed and wipe out burned flour bits with a paper towel if they begin to scorch.

If you prepared onions, nest the warm caramelized onions over or alongside the plated liver. If using bacon, crumble or keep whole slices and arrange alongside the liver. Spoon any flavored pan juices over the liver for extra flavor. Sprinkle chopped fresh parsley over everything and serve with lemon wedges for squeezing over the liver just before eating.

Optional pan sauce: After removing the last batch of liver, lower heat to medium, add 1/4 cup beef or chicken stock (or water) to deglaze the pan, scraping any browned bits with a wooden spoon. Add 1 tablespoon butter and swirl until glossy. Taste and adjust seasoning, then pour over liver and onions/bacon.
