Short answer

After cooking meat, pour off excess fat, add a splash of wine or stock to the hot pan, scrape the base hard, reduce by half, then whisk in cold butter off the heat. That final butter is what makes it glossy rather than watery.

The brown residue left in a pan after frying is concentrated flavour, and a pan sauce is simply dissolving it into liquid and enriching the result. It takes five minutes with ingredients you already have, and it transforms a plain piece of meat or fish.

What you'll need

The pan you cooked in
Wine, stock or water
Cold butter
Shallot or garlic (optional)
Lemon (optional)

Step by step

Take the meat out and rest it, leaving the pan on a medium heat.The residue in the pan is the whole point. Do not wash it.
Pour off most of the fat, leaving the browned bits.Too much fat and the sauce will be greasy.
Soften a chopped shallot or a clove of garlic for a minute if using.Optional but it adds a lot. Do not let the garlic brown.
Add a splash of liquid — wine, stock, cider, or even water.It will hiss and steam. That is the residue lifting off the pan.
Scrape the base hard with a wooden spoon while the liquid bubbles.This is the actual technique. Every scrap you lift is flavour.
Reduce by about half, until it looks slightly syrupy.A minute or two on a decent heat. It should coat the back of a spoon lightly.
Take the pan off the heat and whisk in a knob of cold butter.Off the heat and cold butter — this is what emulsifies it into a glossy sauce rather than an oily one.
Taste, add a squeeze of lemon or a grind of pepper, and pour over the rested meat.Include any juices from the resting plate — that is more flavour.

Tips

Any liquid works. Wine and stock are traditional; cider, vermouth, beer or just water with a stock cube all make a sauce.
Cream instead of butter gives a richer, more stable sauce that will not split if it sits.
The juices that come out of resting meat should always go into the sauce rather than being left on the plate.

Common mistakes

Washing the pan first — The browned residue is the entire flavour base of the sauce.
Adding the butter over heat — It melts and separates into oil instead of emulsifying. Off the heat, cold butter, whisked in.
Not reducing enough — A thin, watery sauce that runs off the plate rather than coating the meat.

Questions people ask

Can I make a pan sauce without wine?

Yes. Stock, cider, beer, or even water with a stock cube all work. The wine adds acidity and depth, but the browned residue provides most of the flavour.

Why did my pan sauce split?

The butter was added over heat, or the pan was too hot. Take it off the heat, then whisk cold butter in a piece at a time.
