Can I use the rendered duck fat instead of the olive oil to sauté the mushrooms?

Yes. Using rendered duck fat in place of the olive oil will brown the cremini mushrooms effectively and add a richer savory flavor because the fat left in the pan carries roasted duck flavor into the vegetables; if there is a large quantity of fat spoon off most so the mushrooms brown rather than fry in excessive oil.

Can I omit the lemon juice or replace it with more cream?

Yes, you can omit the lemon juice, but the lemon provides a bright acidic counterpoint to the heavy cream; leaving it out will make the sauce uniformly richer and less bright, so the recipe includes lemon juice to balance the cream and stock.

Why are my mushrooms steaming instead of browning?

They are likely overcrowded or too wet, which traps steam instead of allowing browning; cook the sliced creminis in a single layer on medium heat and, if the pan seems dry, add a little olive oil or use some rendered fat so moisture can evaporate and the mushrooms can brown.

Why did the sauce separate or look oily after adding the butter?

The sauce usually separates when butter is added too quickly or at too high a temperature; remove the pan from direct heat and whisk in the unsalted butter in small pieces so it emulsifies into the reduced cream and stock for a glossy finish.

How should I store leftovers, and how do I reheat them?

Refrigerate leftovers within 2 hours of cooking — within 1 hour if the room is above 90°F (32°C). USDA general guidance for cooked leftovers is 3 to 4 days in the refrigerator at 40°F (4°C) or below, or the freezer for longer. Reheat until steaming hot throughout, to 165°F (74°C). These are USDA FoodKeeper general guidelines, not a measurement of this specific recipe.

Pan-seared then oven-finished duck breast relies on rendering the skin in a cold skillet and is seasoned with salt and black pepper. The same pan is used to sauté cremini mushrooms and garlic in olive oil with thyme, scraping up browned bits before adding chicken stock and heavy cream for the sauce. A short simmer reduces the stock and thickens the cream so the sauce will coat a spoon. Whisking in unsalted butter at the end produces a glossy, emulsified sauce.

Method

Preheat the oven to 325°F. Place an oven-safe skillet on the stove but keep it off the heat for now.
Pat the duck breast dry. Score the skin in a shallow crosshatch, taking care not to cut into the meat.
Season the duck with half of the salt and half of the black pepper.
Lay the duck in the cold skillet, skin side down. Set the heat to medium. Render and brown the skin until deep golden and much of the fat has melted, about 6 to 8 minutes.
Spoon off most of the rendered fat, leaving a thin coating in the pan. Flip the duck and cook on the meat side for 1 minute.
Transfer the skillet to the oven and cook until the duck is just done to your preference, about 6 to 8 minutes. Move the duck to a warm plate and rest 5 to 7 minutes.
While the duck rests, return the skillet to medium heat. If the pan looks dry, add the olive oil. Add the cremini mushrooms, sliced, and cook until lightly browned, 3 to 4 minutes.
Add the garlic, minced, and the thyme. Cook until fragrant, about 30 seconds.
Pour in the chicken stock and scrape up any browned bits. Simmer for 2 minutes to reduce slightly.
Stir in the heavy cream and the lemon juice. Simmer, stirring, until the sauce thickens enough to coat a spoon, 3 to 4 minutes.
Whisk in the unsalted butter until glossy. Season the sauce with the remaining salt and black pepper.
Slice the duck breast. Spoon the mushroom thyme cream onto plates, top with sliced duck, and finish with parsley, chopped. Serve immediately.

Tips

Pro tip

If the skin starts to darken too quickly while rendering, lower the heat so the fat can melt without scorching.
Adjust sauce thickness by simmering longer to reduce or by adding a splash of chicken stock to loosen.
Chicken thighs can replace duck breast; sear skin-side down until crisp and finish in the oven until cooked through.
Leftover rendered duck fat can be cooled and saved for roasting vegetables or searing meats.
