Ingredients

  • Beef tenderloin medallions: This classic cut is buttery and cooks quickly Choose pieces that are bright red and have minimal connective tissue
  • Salt: Essential to bring out the natural flavors Use kosher or flaky salt for even seasoning
  • Mushrooms: Brown cremini or white button both work They add earthiness and soak up the sauce beautifully Go for firm dry mushrooms with no slimy spots
  • Butter: Adds richness and helps sauté both steak and vegetables Choose unsalted for the best control over saltiness
  • Shallots: They lend a gentle sweetness and subtle bite Choose small firm shallots with no sprouting
  • Cognac or brandy: Lifts and deepens the sauce Flavor is more mellow than whiskey and adds elegance Pick a bottle you would enjoy sipping
  • Beef broth: This forms the backbone of the sauce Go for low sodium so you can adjust the seasoning at the end
  • Worcestershire sauce: Brings savory umami flavor Look for brands without too much added sugar
  • Dijon mustard: For tang Choose a smooth and spicy Dijon for best results
  • Tomato paste: Gives the sauce body and a touch of acidity Grab a tube or can in small amounts to avoid waste
  • Heavy cream: Finishes the sauce rounded and smooth Find one with the highest fat content you can for silkiness
  • Black pepper: Adds warmth and balances rich flavors Use freshly ground for maximum flavor
  • Flat-leaf parsley: A sprinkle adds freshness and color Select bright green leaves without wilting

Step-by-Step Instructions

Season the Steak:
Generously sprinkle both sides of your steaks with salt Set them on a plate and let them rest at room temperature for fifteen to thirty minutes This helps flavors sink in and ensures even cooking
Mix the Sauce Base:
In a small bowl combine beef broth Worcestershire sauce Dijon mustard and tomato paste Whisk until fully blended and smooth Set this aside for later
Sear the Steaks:
Heat two tablespoons of butter in a large skillet over medium high Once the butter foams pat the steaks dry and place them in the pan Sear for about one to four minutes on each side depending on your preferred doneness Use an instant thermometer or your own touch to check temperature
Rest the Steak:
Transfer steaks to a cutting board Tent loosely with foil so they stay hot and juicy while you make the sauce
Sauté the Mushrooms:
Melt the remaining butter in your skillet and add the sliced mushrooms Turn the heat up to high and cook them for three to five minutes stirring until browned and they give off most of their liquid Scoop mushrooms from the skillet and set aside
Cook the Shallots:
Keep the same pan on medium high Add the minced shallots and stir for two minutes until soft and fragrant This builds the base layer of your sauce
Deglaze the Pan:
Pour the cognac or brandy into the pan Scrape up the sticky browned bits on the bottom with a wooden spoon until they blend into the bubbling liquid Let this simmer so the alcohol nearly cooks away
Finish the Sauce:
Return mushrooms to the skillet and pour in your broth mixture Stir and bring the sauce to a gentle boil Cook until it thickens just a bit usually two to three minutes
Add the Cream:
Lower the heat and stir in the heavy cream Let this simmer for two minutes so the sauce melds together perfectly
Season and Serve:
Taste the sauce Adjust with more salt or pepper as you like Place steaks on plates Spoon the warm creamy mushroom sauce over top Finish with fresh parsley and serve right away

One of my favorite moments was making this for my grandmother she always said the sauce reminded her of her favorite restaurant in New York I love how adding fresh parsley at the end brightens up the whole plate

Storage Tips

Steak Diane is best served right after cooking but leftovers can be kept in the fridge for up to two days Store steak and sauce separately if possible Warm gently over low heat to avoid drying out the steak If the sauce thickens in the fridge just splash in a spoonful of water or broth when reheating to loosen it up

Ingredient Substitutions

If you cannot find beef tenderloin look for sirloin tips or even boneless ribeye for similar tenderness You can swap crimini or button mushrooms for portobello or shiitake to change up the flavor Cognac and brandy are interchangeable So if neither is handy try dry sherry for a different but still delicious note

Serving Suggestions

I love pairing this dish with buttery mashed potatoes or crisp roasted potatoes to soak up that silky sauce A pile of garlicky green beans or steamed asparagus rounds out the plate If hosting pass extra sauce at the table so everyone can drizzle more to their taste

Recipe FAQs

→ What cut of beef works best?

Beef tenderloin medallions are ideal for their tenderness and quick cooking. They remain juicy and absorb the sauce well.

→ Can I substitute the cognac?

Yes, brandy is a good alternative. For a non-alcoholic version, use extra beef broth, though some flavor will differ.

→ How do I achieve the best sear?

Pat the medallions dry, use a hot skillet, and avoid overcrowding. Sear for 1-4 minutes per side based on desired doneness.

→ What mushrooms are recommended?

Cremini or button mushrooms hold up well and absorb flavors nicely, making them perfect for the sauce.

→ How can I tell when the steak is done?

Use an instant-read thermometer or the finger test. Internal temps range from 125°F (rare) to 160°F (well done).

→ What sides pair well?

Roasted potatoes, steamed greens, or a fresh salad complement the rich sauce and tender steak beautifully.

Ingredients

→ Main Ingredients

01 4 beef tenderloin medallions, pounded to 3/4 inch thickness
02 Salt, to taste
03 8 oz sliced mushrooms (cremini or button)
04 4 tablespoons butter, divided
05 1/2 cup finely minced shallots
06 4 tablespoons cognac or brandy
07 1/2 cup beef broth
08 4 teaspoons Worcestershire sauce
09 2 teaspoons Dijon mustard
10 2 teaspoons tomato paste
11 1/3 cup heavy cream
12 Freshly ground black pepper, to taste
13 1 tablespoon flat-leaf parsley, minced

Directions

Step 01

Season both sides of the beef medallions with salt and allow them to sit at room temperature for 15-30 minutes.

Step 02

In a small bowl, combine the beef broth, Worcestershire sauce, Dijon mustard, and tomato paste. Mix well and set aside.

Step 03

Heat 2 tablespoons of butter in a large skillet over medium-high heat. Pat the beef medallions dry and add them to the skillet. Sear the steaks for 1-4 minutes per side based on desired doneness, checking with an instant-read thermometer or the finger test (rare: 125°F; medium rare: 135°F; medium: 145°F; well done: 160°F).

Step 04

Transfer the cooked steaks to a cutting board and tent with foil to keep them warm.

Step 05

In the same skillet, melt the remaining 2 tablespoons of butter over high heat. Add the sliced mushrooms and sauté until they release their moisture and begin to brown, about 3-5 minutes. Remove the mushrooms from the pan and set aside.

Step 06

Reduce the heat to medium-high and add the minced shallots to the skillet. Sauté for 2 minutes, stirring occasionally.

Step 07

Pour in the cognac or brandy to deglaze the pan, scraping up any browned bits from the bottom. Cook until the alcohol has nearly evaporated.

Step 08

Stir in the broth mixture and the sautéed mushrooms. Bring the sauce to a boil and cook until it thickens slightly, about 2-3 minutes.

Step 09

Reduce the heat to low and stir in the heavy cream. Simmer for 2 minutes, allowing the flavors to meld. Adjust seasoning with salt and black pepper as needed.

Step 10

Plate the steaks and spoon the warm Diane sauce with mushrooms over the top. Garnish with finely chopped parsley and serve immediately.

Notes

  1. Allow the steaks to come to room temperature before searing for even cooking.
  2. Use a thermometer for accurate doneness levels.
