Steak Diane

Steak Diane is such a delicious, classic beef dish. It's essentially a pan-fried steak topped with a creamy, savory steak sauce. And let me tell you something: it's pure, unadulterated bliss.

In fact, it's more than bliss. Just wait until you try it.

The steak is obviously very important here, but the secret is the sauce. Ohhh, the sauce. It's made in the same skillet that the steak is cooked in, so it picks up all of those delicious browned savory bits, but it also has things like garlic, onion, thyme, cream, balsamic reduction, and a big heaping spoonful of grainy mustard. Sometimes when steak Diane is made in restaurants, the sauce is flambéed. But this version won't leave you with singed eyebrows—just pull the skillet off the heat when you add the brandy to avoid any risk of a flare-up. It's a cinch!

What cut of steak is best for steak Diane?

I love a strip steak for a dish like this. I've also made it with filet mignon and that works great too. Whichever cut of steak you choose, just make sure you don't overcook it. That would be a crime. In fact, I'm pretty sure it is a crime in Osage County. Don't quote me on that.

I like my steak cooked medium-rare, which, if you use a meat thermometer, is about 130 degrees Fahrenheit internally. Use this handy steak doneness chart as a guide!

Can you make steak Diane ahead of time?

This is one dish that's best served right away. The sauce comes together quickly, so the best thing you can do to work ahead is make sure you have all your ingredients at arm's length. Go ahead and dice the red onion, slice the garlic, mince the chives, and measure out the other ingredients so they're ready to go when needed.

What do you serve with steak Diane?

I usually like to serve steak with a vegetable like sautéed green beans or creamed spinach and one of these potato side dishes. You’ll want something to sop up every last bit of the pan sauce so plan accordingly.

How To Make Steak Diane

INGREDIENTS

Strip steaks: Strip steaks are a great pick for Steak Diane because they’re tender, flavorful, and cook up beautifully in a skillet. They have plenty of rich, beefy flavor, which means they can hold their own against that luscious pan sauce.

Salt and pepper: Be sure to generously season every inch of the steaks so each bite is full of flavor.

Butter: Butter adds richness and helps the steaks develop a golden, flavorful crust. It also forms the base of the sauce. If unsalted butter is what you have, that works too—just adjust the salt as needed.

Olive oil: A little olive oil helps the steaks sear nicely and keeps the butter from browning too fast in the pan.

Red onion: This adds a little sweetness and bite to the sauce. Once it cooks down, it turns soft and mellow and helps build lots of flavor in the pan. Shallots would be a great substitute if you happen to have them.

Garlic: Garlic gives the sauce a certain savoriness that can’t be beat. Slicing it keeps the flavor present without overpowering the whole dish.

Thyme: The flavor of thyme works so well with steak and cream sauce. Fresh is best, but a small pinch of dried thyme will do the job if that’s what you’ve got.

Brandy: Brandy is one of the classic ingredients in steak Diane, and it gives the sauce so much depth and flavor. It adds a little warmth and sweetness and helps loosen all those delicious browned bits from the pan. Whiskey works too, if you want to use that instead. If you’d rather skip the alcohol, you can use beef broth but you won’t get quite the same flavor.

Heavy cream: Heavy cream is what makes the sauce rich, smooth, and downright dreamy. It softens the sharpness of the mustard and brings the whole sauce together.

Whole-grain mustard: This adds a little tang and texture, which helps balance the richness of the cream and butter.

Balsamic reduction: Also known as balsamic glaze, balsamic reduction adds a touch of sweetness and acidity, which keeps the sauce from feeling too heavy. Since it’s concentrated, you only need a little bit. Here’s a homemade balsamic glaze recipe, but the store-bought stuff works great, too.

Chives: Chives get sprinkled on at the end for a little fresh flavor and a pretty pop of green. They brighten up the whole dish.

STEP-BY-STEP INSTRUCTIONS

Start by taking the steaks out of the fridge about 30 minutes before cooking so they can lose a little of their chill. This helps them cook more evenly and gives you a better sear. When you’re ready, season them generously all over with salt and pepper.

Heat a large, heavy skillet until it’s nice and hot, then add the butter and oil. Once the butter is melted and foamy, add the steaks. They should sizzle the second they hit the pan. Let them cook undisturbed for a few minutes on each side so they can develop a deep golden-brown crust. Once they’re done to your liking, transfer them to a cutting board to rest. Resting is important here—it gives the juices time to settle back into the meat so the steaks stay tender and flavorful when sliced.

While the steaks rest, build the sauce right in the same skillet. Add the onion, garlic, and thyme to the steak drippings and cook until the onion softens and everything smells rich and fragrant. Cut off the heat while you add the brandy, then stir to loosen all the bits from the bottom—they’re packed with flavor. Crank the heat back up and let the brandy bubble for a minute so it cooks down slightly and mellows.

Stir in the heavy cream, mustard, and balsamic reduction and let the sauce simmer until it turns silky, creamy, and just thick enough to coat the back of a spoon. This only takes a couple of minutes, so keep an eye on it.

Slice the steaks against the grain for the most tender bites. If you look closely, you’ll see the muscle fibers running in one direction—cutting across them shortens those fibers and makes the steak easier to chew.

Transfer the steak to your plate and spoon the warm, creamy sauce over the top. Sprinkle on some fresh chives and enjoy every delicious bite!
