Ingredients You’ll Need

Each ingredient in this Steak Diane with Mushroom and Cream Sauce Recipe plays a role in creating the perfect balance of flavors and texture. I always recommend using fresh herbs and quality beef if you can—your taste buds will thank you!

• Beef tenderloin steaks: These steaks are tender and cook quickly, perfect for this sauce; look for filet mignon cuts.
• Kosher salt and freshly cracked pepper: Simple seasoning that enhances the beef without overpowering it.
• Unsalted butter and vegetable or canola oil: Butter for flavor, oil to prevent burning during cooking.
• Cremini mushrooms: They have a deeper flavor than white mushrooms, great for a rich sauce.
• Shallots: I like these for their mild, sweet onion flavor that awakens the sauce without being sharp.
• Tomato paste: Adds umami depth and slight sweetness to the sauce.
• Garlic cloves: Fresh garlic is key – it’s aromatic and blends beautifully here.
• Red pepper flakes: Just a pinch to give a subtle heat that wakes up your palate.
• Flour: Used to thicken the sauce to the perfect velvety consistency.
• Beef broth (reduced sodium): A good base for the sauce, making sure it’s not too salty.
• Worcestershire sauce and soy sauce: These boost umami and add complexity.
• Dijon mustard: For a slight tang and to round out the flavors.
• Beef bouillon (base, powder, or cube): Adds an extra savory punch.
• Dried oregano and thyme (or fresh): Classic herbs that complement beef and mushrooms perfectly.
• Heavy cream: The star that makes this sauce luxuriously creamy.
• Fresh parsley: Adds brightness and fresh color at the end.
• Mashed potatoes: For serving – they soak up all the delicious sauce!

Variations

I love customizing this Steak Diane with Mushroom and Cream Sauce Recipe depending on the season or what’s in my fridge. You should feel free to make it your own – that’s part of the fun and joy of cooking this dish!

• Mushroom swap: I’ve swapped in shiitake or portobello mushrooms for a deeper earthiness, and it’s always a hit with guests.
• Herb variations: Sometimes I add fresh tarragon or rosemary instead of oregano and thyme, which gives a lovely aromatic twist.
• Cream-free version: If you’re avoiding dairy, try substituting with unsweetened almond milk and a bit of cornstarch to thicken – it requires tweaking but works well!
• Spice it up: Adding a splash of brandy or cognac (carefully flambéed) really makes it feel like a special occasion dish.

How to Make Steak Diane with Mushroom and Cream Sauce Recipe

Step 1: Preparing and seasoning the steaks

First things first, pat your steaks dry with paper towels. I learned that this step is crucial – moisture on the meat surface will steam instead of sear, and you want that beautiful crust. I like to press each steak down gently with my palm to ensure they’re about an inch thick, so they cook evenly. Season them liberally all over with kosher salt and freshly cracked pepper. If you can, salt them at least an hour ahead and let them dry brine in the fridge – it really boosts juiciness and flavor. If you’re short on time, season immediately before cooking and keep them at room temperature.

Step 2: Searing the steaks to perfection

Heat a large skillet over medium-high heat — this is key to getting a nice sear without burning. Add a tablespoon each of butter and oil so you get the flavor of butter but the oil’s higher smoke point protects it. Pop the steaks in the pan without overcrowding. Cook for about 2 minutes per side for medium-rare, aiming for an internal temp of 130°F. If you haven’t got a meat thermometer, I truly recommend getting one; it takes all the guesswork out. Once done, transfer the steaks to a plate and tent loosely with foil to rest – this keeps them juicy.

Step 3: Caramelizing mushrooms

Using the same skillet (embrace the lovely beefy drippings), melt two tablespoons butter with a tablespoon olive oil over medium heat. Add the sliced cremini mushrooms, spreading them out in a single layer as much as you can; they’ll shrink as they cook, so you can rearrange for even browning. Cook undisturbed for 3 minutes, then flip and repeat until golden and caramelized. This step imparts so much flavor—don’t rush it! Once done, set them aside on a plate.

Step 4: Building the sauce flavors

In the same pan, melt two more tablespoons of butter over medium heat. Toss in minced shallots and sauté gently for 3–4 minutes until soft and fragrant. Then stir in tomato paste, garlic, and a pinch of red pepper flakes, cooking for just 30 seconds to awake those deep flavors without burning. If you’re feeling fancy, add a splash of cognac here to flambé and deglaze the pan—but it’s totally optional and still delicious without it.

Step 5: Thickening and finishing the sauce

Sprinkle in the flour and cook for one minute, whisking constantly. This helps cook out the raw flour taste and picks up all those browned bits stuck to the pan. Slowly whisk in the beef broth, then add Worcestershire sauce, soy sauce, Dijon mustard, beef bouillon, oregano, and thyme. Turn the heat to low and let it simmer gently until thickened. Then stir in the cream, parsley, and your caramelized mushrooms. Warm through, and you’ll have a sauce that’s luscious, full-bodied, and worthy of a five-star dinner.

Step 6: Serving your masterpiece

Plate the steaks alongside a generous scoop of creamy mashed potatoes (seriously, the sauce soaks into those perfectly). Spoon over the mushroom cream sauce, garnish with fresh parsley or chives, and give it a final taste for salt and pepper. This step always feels like magic to me – that first bite is pure bliss.

How to Serve Steak Diane with Mushroom and Cream Sauce Recipe

Garnishes

I always finish this dish with a sprinkle of fresh flat-leaf parsley for a pop of vibrant color and freshness. Chopped chives are another favorite of mine because their mild oniony bite contrasts beautifully with the creamy sauce. Sometimes, just a little lemon zest over the top adds a surprising brightness that lifts the whole plate.

Side Dishes

Mashed potatoes are my go-to side because they soak up that luscious mushroom cream sauce perfectly. Roasted baby carrots or green beans with a touch of garlic also complement the rich steak wonderfully. For a lighter option, a crisp green salad with a tangy vinaigrette balances the richness beautifully.

Creative Ways to Present

For special dinner parties, I love plating each steak medallion over a swirl of mashed potatoes with the mushroom sauce artistically drizzled over it. Topping with a small sprig of thyme or edible flowers adds an elegant touch. You can also serve the sauce in a beautiful gravy boat on the side so guests can add as much as they like.

Make Ahead and Storage

Storing Leftovers

I usually store leftover steaks and sauce together in an airtight container in the fridge for up to 3 days. The sauce keeps the meat moist, which is great since leftovers can sometimes dry out. Just be sure to let it cool before sealing to avoid condensation.

Freezing

If you want to freeze this Steak Diane with Mushroom and Cream Sauce Recipe, separate the steaks and sauce for best texture. Freeze the sauce in airtight containers for up to 2 months. Steaks can be frozen but may lose some tenderness, so I recommend freezing only if necessary.

Reheating

When reheating, gently warm the sauce on low heat while stirring to prevent splitting the cream. Warm the steaks separately in a skillet over medium-low heat or in the oven wrapped loosely in foil to avoid drying out. Pour sauce over just before serving for that fresh-from-the-kitchen taste.
