What You’ll Need to Make This Recipe
The star of this dish is beef tenderloin, known for its tenderness and mild flavor. It cooks quickly and pairs beautifully with the rich sauce.
Butter, garlic, and onion create a flavorful base, while beef broth and cream give the sauce its depth and silky texture. Dijon mustard and Worcestershire sauce add a tangy, savory kick that makes the sauce truly stand out.
A splash of brandy or cognac adds warmth and enhances the overall flavor, while fresh parsley brightens the dish at the end.

How to Make Classic Steak Diane Step by Step
Step 1: Season the Steaks
Pat the steaks dry and season both sides generously with salt and black pepper. This helps create a flavorful crust when searing.
Step 2: Sear the Steaks
Heat olive oil in a large skillet over medium-high heat. Add the steaks and cook for about 3 to 4 minutes per side for medium-rare, or until they reach your preferred doneness. Remove the steaks and let them rest.
Step 3: Start the Sauce
In the same skillet, melt the butter over medium heat. Add the chopped onion and cook until soft and translucent, about 3 to 4 minutes.
Step 4: Add Garlic and Deglaze
Stir in the garlic and cook briefly until fragrant. Carefully pour in the brandy or cognac, allowing it to simmer and reduce slightly while lifting the flavorful bits from the bottom of the pan.
Step 5: Build the Sauce
Add the beef broth, heavy cream, Dijon mustard, and Worcestershire sauce. Stir well and let the sauce simmer for a few minutes until it thickens slightly.
Step 6: Finish the Dish
Return the steaks to the skillet and spoon the sauce over them. Let them warm through for another minute or two.
Step 7: Garnish and Serve
Sprinkle with freshly chopped parsley and serve immediately, with plenty of sauce drizzled over the top.
Expert Tips
- Let the steaks come to room temperature before cooking for even results.
- Don’t overcrowd the pan—this helps achieve a good sear.
- Use a heavy skillet for better heat retention.
- Be careful when adding brandy—add it slowly and keep the heat controlled.
How to Store and Reheat It
Store leftovers in an airtight container in the refrigerator for up to 2 days.
To reheat, warm gently in a skillet over low heat, adding a splash of broth or cream if needed to loosen the sauce.
What to Serve With
Steak Diane pairs beautifully with mashed potatoes, buttered noodles, or steamed vegetables. A side of crusty bread is also perfect for soaking up the extra sauce.
