Ingredients & Why They Work
This Easy Steak Diane with Mushroom Sauce Recipe uses ingredients that build layers of flavor without fuss. Each one plays a role – from the tender filet mignon to the earthy cremini mushrooms, and the cocktail of sauces and herbs that make the pan sauce sing. Here’s what you’ll need and why each item makes a difference.
- Beef tenderloin steaks (filet mignon): These steaks are lean, tender, and perfect for quick searing to juicy medium-rare.
- Kosher salt and freshly cracked pepper: Simple seasonings that let the flavor of the steak shine and help form a delicious crust.
- Unsalted butter and vegetable/canola oil: Butter adds richness while the oil prevents burning – the combo gives you perfect sear and flavor.
- Cremini mushrooms: Their slightly nutty, earthy flavor deepens the sauce and caramelize beautifully.
- Shallots: Mellow and sweet, they build gentle savory notes in the sauce.
- Tomato paste: Adds concentrated flavor and depth, intensifying the sauce complexity.
- Garlic: Classic aromatic that brings warmth to the dish.
- Red pepper flakes: Just a bit of subtle heat to awaken the flavors.
- Flour: Used for thickening the sauce, giving it that luscious texture.
- Beef broth (reduced sodium): The base of the sauce, providing meaty richness without overpowering saltiness.
- Worcestershire sauce, soy sauce, Dijon mustard: These bring umami, tang, and a mild bite — the secret trio that layers flavor.
- Beef bouillon: Adds an extra boost of beefy depth.
- Dried oregano and thyme: Classic herbs that complement the meat and mushrooms perfectly.
- Heavy cream: Smooths and enriches the sauce for that velvety finish.
- Fresh parsley: Adds a fresh, bright contrast at the end.
- Mashed potatoes: Bonus! The sauce is so generous, you’ll have plenty to pour over hearty creamy potatoes.
Make It Your Way
I love tweaking this Easy Steak Diane with Mushroom Sauce Recipe depending on my mood or what I have on hand. It invites all kinds of little changes that make it truly yours - and you’ll enjoy that kind of freedom in the kitchen.
- Variation: Adding a splash of cognac or brandy when sautéing the shallots and garlic really lifts the sauce – I learned this combo from an old cooking class and now rarely skip it.
- Vegetarian substitution: Try hearty portobello mushrooms instead of steak, and adjust the cooking time – it’s a satisfying twist that keeps the rich sauce front and center.
- Herb swaps: Fresh tarragon or rosemary can give the sauce a different but equally wonderful aroma; feel free to experiment to find your favorite herbal punch.
Step-by-Step: How I Make Easy Steak Diane with Mushroom Sauce Recipe
Step 1: Season and Prep the Steaks
Start by patting your filet mignon steaks dry with paper towels – this is crucial for a good sear. Then, press them gently with your palm so they’re about an inch thick. Season generously on all sides with kosher salt and freshly cracked pepper. If you have time, let them sit at room temperature for about 30–60 minutes; it helps achieve even cooking and tender results. If you're short on time, don’t sweat it – seasoning right before cooking works fine too.
Step 2: Sear the Steaks to Perfection
Heat a heavy-bottomed skillet over medium-high heat; once it’s really hot, add a tablespoon each of butter and oil. When the butter is melted and foamy, add the steaks. Cook about 2 minutes per side for medium-rare – I always use a meat thermometer and aim for 130°F internal temperature. Take the steaks off the pan and let them rest tented with foil; resting keeps the juices locked in.
Step 3: Caramelize the Mushrooms Just Right
In the same skillet, melt two tablespoons butter and one tablespoon olive oil over medium heat. Crank the heat to medium-high and add your sliced cremini mushrooms. Give them a stir to coat, then try to arrange them in a single layer – this is key for a good caramelization with crispy edges. Let them cook undisturbed for about 3 minutes per side, flipping once to golden brown each side. Remove and set aside.
Step 4: Build the Rich Sauce with Aromatics
Now, melt two more tablespoons of butter in the skillet over medium heat. Add minced shallots and let them soften and turn translucent, about 3-4 minutes. Stir in the tomato paste, garlic, and red pepper flakes, cooking just 30 seconds until fragrant – don’t let the garlic burn. If you’re feeling fancy, add a splash of cognac here to deglaze the pan and boost flavor, cooking until mostly evaporated.
Step 5: Thicken and Finish the Sauce
Sprinkle the flour over the aromatics and cook, stirring constantly for about a minute to remove the raw taste. Gradually whisk in beef broth, then add Worcestershire sauce, soy sauce, Dijon mustard, beef bouillon, oregano, and thyme. Bring the sauce to a gentle simmer and let it thicken – it’s okay if it’s just slightly thickened now since cream will enrich it further. Stir in heavy cream, fresh parsley, and caramelized mushrooms. Warm it through and adjust seasoning after tasting.
Step 6: Serve with Style
Plate your rested steaks alongside generous scoops of creamy mashed potatoes, then lavish the mushroom sauce over the top. Garnish with more fresh parsley or chives for a burst of color and fresh flavor.
Top Tip
From my many times cooking this Easy Steak Diane with Mushroom Sauce Recipe, I’ve learned a few small but game-changing tips that’ll help you get the best results with less guesswork.
- Dry Steaks First: Moisture is the enemy of a good sear, so always pat your steaks dry before seasoning and cooking.
- Single Layer Mushrooms: Spreading out mushrooms in one layer helps them caramelize brilliantly instead of steaming and turning soggy.
- Careful with Garlic: Add garlic toward the end of sautéing aromatics to avoid burning its delicate flavor.
- Let Steaks Rest: A quick 5-minute rest under foil keeps juices locked in for the juiciest bite.
How to Serve Easy Steak Diane with Mushroom Sauce Recipe
Garnishes
I keep it simple with freshly chopped parsley and sometimes snip some chives for a mild oniony pop. These fresh herbs add a nice color contrast and brighten up all that richness.
Side Dishes
Mashed potatoes are my go-to because the creamy texture soaks up the luscious mushroom sauce perfectly. I also like serving this with roasted green beans or a crisp mixed green salad for some fresh balance on the plate.
Creative Ways to Present
For a dinner party, I’ve served the steaks on shallow bowls with the sauce ladled over the top and sprinkled with edible flowers and minced herbs. It looks stunning and feels really special, turning a cozy dish into a centerpiece.
Make Ahead and Storage
Storing Leftovers
I store leftover steak and sauce separately in airtight containers in the fridge. This keeps the steak from getting overwhelmed by moisture and helps preserve the sauce’s texture best.
Freezing
The mushroom sauce freezes really well on its own, but I don’t recommend freezing the steaks cooked this way as the texture suffers. Instead, freeze the sauce in small containers for quick weeknight meals.
Reheating
Gently reheat the sauce on low heat with a splash of broth or cream to loosen it, stirring often. Warm leftover steak slices gently in a skillet or the microwave, but try not to overcook to avoid toughness.
Frequently Asked Questions:
Absolutely! While filet mignon is tender and ideal for this recipe, you can also use ribeye, sirloin, or strip steaks. Just adjust the cooking times to avoid overcooking tougher cuts.
You can substitute beef broth with a good-quality beef stock, mushroom broth, or even a mix of water and beef bouillon cubes dissolved to taste. Just be mindful of salt levels when adjusting.
Yes! You can slice and prep mushrooms and shallots earlier, and even make the sauce up to the point before adding cream and mushrooms, then refrigerate. Reheat gently and finish the sauce just before serving to save time.
Using a reliable meat thermometer is your best friend here. For medium-rare, aim for 130°F internal temperature, and always let the steaks rest after searing. This makes the juicy difference!

This Easy Steak Diane with Mushroom Sauce Recipe really holds a special place in my recipe arsenal. It’s the kind of dish that makes you feel like a pro without spending hours in the kitchen, and the sauce is just downright addictive.

- Unsalted butter and vegetable or canola oil for cooking
Sauce
- 4 tablespoons unsalted butter, divided

- 6 ounces cremini mushrooms, sliced ¼-inch thick
- 1 large shallot or 2 smaller/medium, minced
- 1 tablespoon tomato paste
- 3 garlic cloves, minced
- ⅛ teaspoon red pepper flakes
- 3 tablespoons flour
- 1 14.5 oz. can reduced-sodium beef broth
- 1 tablespoon Worcestershire sauce
- 2 teaspoons reduced sodium soy sauce
- 1 teaspoon Dijon mustard
- 1 teaspoon beef bouillon (base, crushed cube, or powder)
- ½ teaspoon dried oregano
- ½ teaspoon dried thyme
- ⅓ cup heavy cream
- 3 tablespoons fresh parsley (or 1 teaspoon dried)
To Serve
- Mashed potatoes (this recipe makes a generous amount for the potatoes)
- Fresh parsley for garnish
- Chives (optional)
Instructions
- Season Steaks: Pat the steaks dry on both sides with paper towels. Press each medallion with the palm of your hand to flatten it to about a 1-inch even thickness. Season all sides with kosher salt and freshly cracked pepper. Season the steaks right before cooking if you don’t have time to dry brine.
- Cook Steaks: Heat a large, heavy-bottomed skillet over medium-high heat. Once hot, add one tablespoon of butter and one tablespoon of oil. Add the steaks and cook to desired temperature, about 2 minutes per side for medium-rare (130°F internal temperature). Remove steaks to a plate to rest and tent with foil.
- Caramelize Mushrooms: Melt two tablespoons of butter with one tablespoon olive oil over medium heat in the pan drippings. Increase heat to medium-high, add mushrooms, and stir to coat. Arrange mushrooms in a single layer. Cook for 3 minutes per side or until golden brown. Remove mushrooms to a plate.
- Sauté Sauce Aromatics: Add two tablespoons butter to the now-empty skillet and melt over medium heat. Add minced shallot and sauté for 3-4 minutes until softened. Stir in tomato paste, garlic, and red pepper flakes and sauté for 30 seconds.
- Finish Sauce: Add flour and cook 1 minute, scraping browned bits from pan bottom. Reduce heat to low and slowly whisk in beef broth. Add Worcestershire sauce, soy sauce, Dijon mustard, beef bouillon, oregano, and thyme. Bring to a simmer until thickened. Stir in heavy cream, fresh parsley, and cooked mushrooms. Warm through.
- Serve: Plate steaks with mashed potatoes and spoon sauce over the top. Garnish with fresh parsley or chives. Season with salt and pepper to taste after tasting sauce.
