Chicken Liver Mousse Pâté Recipe

Prepare livers

Rinse chicken livers under cold water and pat dry with paper towels. Trim away any connective tissue, greenish bits, or large sinews. Cut the larger lobes in half so pieces are uniform in size for even cooking.

Marinate briefly in wine

Place the trimmed livers in a shallow bowl and pour the burgundy wine over them. Cover and refrigerate for 20–30 minutes to mellow flavor and remove blood. After marinating, drain the livers and reserve the wine. Pat livers dry thoroughly.

Cook aromatics

In a large skillet over medium heat, melt 2 tablespoons of the unsalted butter. Add the finely chopped shallot and cook, stirring, until softened and translucent, about 3–4 minutes. Add the minced garlic and cook 30 seconds until fragrant but not browned.

Sear livers

Increase heat to medium-high and add the drained, patted-dry livers to the pan in a single layer. Sear 1–2 minutes per side until the exterior is browned but the center is still slightly pink (internal temperature ~145°F/63°C). Avoid overcooking to keep mousse silky. Do not crowd the pan; cook in batches if necessary.

Deglaze and reduce

Return all seared livers to the pan (or transfer them into the pan if cooked in batches). Pour the reserved burgundy wine and the brandy over the livers and scrape up browned bits from the pan. Add the chopped fresh thyme. Simmer gently until the liquid is mostly reduced, about 3–5 minutes — there should still be a small amount of pan juices.

Simmer with cream

Pour in the heavy cream and bring to a gentle simmer. Cook 2–3 minutes until the cream is warmed and slightly thickened. Taste a small piece for seasoning, then remove from heat. Let the mixture cool for 5 minutes so it's warm but not hot when transferred for blending.

Blend to a mousse

Transfer the entire mixture (livers, cream, pan juices, aromatics) to a food processor or high-speed blender. Add the remaining 2 tablespoons of unsalted butter and pulse until smooth. With the motor running, add the cold butter tablespoons one at a time to mount the mousse and create a glossy texture. Process until the mousse is perfectly smooth, about 1–2 minutes. If desired, pass the purée through a fine-mesh sieve into a bowl for an ultra-silky texture, pressing with a spatula.

Season and chill

Season the mousse with salt (about 1½ teaspoons) and freshly ground black pepper to taste, adjusting if needed. Spoon the mousse into a loaf pan or small ramekins and smooth the top. Press plastic wrap directly onto the surface (to prevent a skin) or add a thin layer of melted butter to seal. Refrigerate at least 3 hours or overnight to firm up and allow flavors to meld.

Prepare mustard and cornichons

If you prefer a red-wine mustard, stir 1–2 teaspoons of reserved reduced burgundy wine (optional) into the whole-grain mustard to taste. Arrange halved cornichons in a small bowl. Chop parsley if using.

Unmold and finish

Remove the pâté from the refrigerator. If you used a loaf pan, run a thin-bladed knife around the edge and invert onto a serving plate. Alternatively, serve directly from ramekins. If you sealed with melted butter, brush the top lightly with softened butter to bring sheen and richness.

Serve

Serve the chicken liver mousse chilled with spoonfuls of burgundy-style mustard, cornichons on the side, toasted baguette slices or crackers, and optional chopped parsley. Encourage guests to spread a thin layer of pâté on toast and add a cornichon and a touch of mustard for contrast.

Storage

Keep covered in the refrigerator for up to 4 days. For longer storage, freeze in an airtight container for up to 1 month; thaw overnight in the refrigerator before serving.
