This steak dish is the perfect main course for any dinner party, date night, or special occasion. The rich mushroom wine sauce pairs beautifully with the tender meat, creating an indulgent and flavorful experience that is sure to impress.

When serving this dish, I recommend plating the flank steak on a bed of creamy mashed potatoes or truffle risotto to balance out the richness of the sauce. A side of sautéed spinach or roasted asparagus also complements the richness of the dish without overwhelming it.

As for wine pairings, I suggest opting for a full-bodied red wine like a bold Cabernet Sauvignon or a smooth Merlot to match the intensity of the mushroom wine sauce. If you prefer a lighter-bodied option, a Pinot Noir would also work well.

For those who don’t drink alcohol, a tall glass of iced tea or sparkling water with slices of fresh lemon and lime are equally refreshing with this savory dish.

With its flavorsome combination of steak and mushroom wine sauce, your guests won’t be able to resist seconds!

Make-Ahead, Storing and Reheating

This flank steak with mushroom wine sauce recipe is a great option for meal prep or entertaining guests. You can easily make the dish ahead of time and store it in the refrigerator or freezer until you’re ready to serve it.

To make ahead, simply prepare the recipe as directed and let the steak and mushroom sauce cool to room temperature. Once cooled, you can store the steak and sauce separately in airtight containers in the refrigerator for up to three days.

If you’d like to store the dish for longer, it’s best to freeze it. To do this, wrap the cooled steak tightly in plastic wrap, then place it in a freezer-safe bag or container. The mushroom sauce can also be placed in a separate container and frozen. When you’re ready to eat, thaw both items overnight in the refrigerator, then reheat.

To reheat the steak, preheat your oven to 350°F (175°C). Remove it from the refrigerator and let it sit out at room temperature for 30 minutes before reheating. Place the steak on a baking sheet and cook for 10-15 minutes or until heated through.

To reheat the mushroom wine sauce, simply transfer it to a saucepan and heat over medium-low heat, stirring occasionally until warmed through. If the sauce has thickened too much in storage, simply add a splash of beef broth or water to thin it out before reheating on the stovetop.

By making this dish ahead of time and properly storing it, you can save time and ensure that your meal is delicious every time you serve it.

Tips for Perfect Results

Here are some important tips to keep in mind while preparing the flank steak in mushroom wine sauce recipe to achieve perfect results:

1. Marinate the Flank Steak with Red Wine: To tenderize the meat and add flavor, marinate the flank steak with red wine for at least 2 hours or overnight.

2. Sear the Flank Steak: Searing the flank steak over high heat will help lock in the juices and give it a nice crust. Do not overcrowd the pan and cook each side for about 3-4 minutes to achieve medium-rare.

3. Use Fresh Mushrooms: Always use fresh mushrooms as canned mushrooms tend to have a different texture and taste. Slice them thinly and cook them over high heat until they are tender.

4. Thicken the Mushroom Wine Sauce: Once you have added the wine to the pan, allow it to reduce by half before adding in other ingredients. Mix cornstarch with water to create a slurry which can be added to thicken your sauce.

5. Rest and Slice against the Grain: After cooking, rest the steak for at least five minutes before slicing it thinly against the grain. This will make the meat easier to eat and more tender.

By following these tips, you can create an amazing dish that is sure to impress your family and friends. Happy cooking!


As a chef, I am always open to questions about the recipes I share. So, I’ve compiled some frequently asked questions about this Flank Steak in Mushroom Wine Sauce recipe to help you achieve the best result possible. These will cover key areas like substitutions and variations, serving and pairing options, storage, and tips for perfecting your dish.

What is the best way to cook flank steak so it’s tender?

When preparing these steaks, it is essential to use high heat for a brief interval to achieve a satisfactory texture and flavor. Adding cooking spray or olive oil to the pan is also recommended, followed by four minutes of cooking on each side. It is crucial to cook it to the preferred temperature, aiming for a medium rare, to avoid rubbery and tough meat.

What wine goes best with flank steak?

As a sommelier, I am always asked about the best red wines out there. Cabernets are a popular choice due to their versatile nature and wide appeal, often referred to as the “people pleaser” of red wines. Another excellent option is Zinfandel, boasting bold fruit flavors and a hint of spice. Malbec warms the heart with its robust structure and earthy undertones while Syrah, or Shiraz, brings the richness of dark berries and a touch of smokiness. Above everything else, the most significant factor in choosing a top-quality red wine is your own personal preference.

What wine goes with steak and mushroom sauce?

When it comes to pairing wine with beef dishes that are smothered in a creamy mushroom sauce, opting for a full-bodied red wine like Cabernet Sauvignon or Syrah would be a great choice. These wines not only complement the earthy richness of the sauce but also provide a bold flavor that can stand up to the hearty taste of beef.

Bottom Line

In conclusion, this flank steak in mushroom wine sauce recipe is a must-try for steak lovers who want to elevate their dining experience. With its succulent meat and savory mushroom sauce, it’s a delicious and satisfying meal that’s perfect for any occasion. Plus, the recipe is easy to follow, and you can even make some substitutions and variations to suit your preference.

The red wine used in this recipe gives the sauce its richness and depth of flavor, while the fresh mushrooms add a pleasant earthy taste that complements the beef perfectly. And since flank steak is leaner than other cuts of beef, it’s a healthier option. You can grill or pan-sear the steak to perfection, depending on how you like it cooked.

Don’t forget to pair this dish with a fine glass of red wine such as Pinot Noir or Cabernet Sauvignon. The tangy taste of red wine perfectly complements the meat, making for a truly indulgent dining experience.

Overall, this flank steak in mushroom wine sauce recipe is an excellent addition to your repertoire of dishes that are sure to impress your guests or satisfy your cravings. So what are you waiting for? Grab some fresh ingredients, whip up this satisfying meal, pour yourself a glass of wine, and enjoy!
