There are a few different substitutions and variations you can make to this Flank Steak with Merlot Mushrooms and Pearl Onions recipe based on your preferences or dietary restrictions. Here are some ideas:

– Mushrooms: If you are not a fan of cremini mushrooms, you could use sliced button mushrooms instead. Or, for a more luxurious treat, try using some shiitake mushrooms.

– Onion powder: If you do not have onion powder on hand, you could substitute it with fresh minced onions or shallots. Keep in mind that the texture and flavor may differ slightly.

– Pearl onions: If you do not like pearl onions or cannot find them at your grocery store, you could substitute them with regular onions. Simply slice them into thin rounds and sauté them until they are soft and caramelized.

– Red wine: Merlot is an excellent choice for this recipe, but you could also use another dry red wine such as cabernet sauvignon or pinot noir.

– Flank steak: This recipe would work well with other cuts of beef, such as filet mignon or a stuffed flank steak. You could even use marinated flank steak for added flavor.

– Creamy mushroom sauce: To add a little richness to the dish, try making a creamy mushroom sauce instead of the red wine sauce. Simply sauté some mushrooms until they are tender, then add cream and a little bit of cheese to thicken the sauce.

This Flank Steak with Merlot Mushrooms and Pearl Onions Recipe is a great option for meal prepping or hosting dinner parties. Luckily, it’s also easy to make ahead of time and reheat for later meals!

Making Ahead: After cooking, allow the steak to cool to room temperature before storing in an airtight container in the refrigerator for up to 4 days. The mushroom sauce can also be stored separately in a separate container in the fridge for up to 3 days.

Reheating: To reheat, simply bring the steak and mushroom sauce to room temperature. Place the steak on a baking sheet lined with foil and bake in a preheated oven at 375°F for 10-15 minutes or until heated through. Alternatively, you can heat up the steak in a skillet over medium heat for 2-3 minutes per side until desired temperature is achieved.

Tips for Perfect Results

When cooking Flank Steak With Merlot Mushrooms and Pearl Onions, there are several tips that you can follow for perfect results. Here are some tips to help you create a delicious meal.

1. Properly season the steak

Before cooking the steak, make sure to generously season both sides with salt and freshly ground black pepper. You can also add garlic powder and onion powder on both sides of the meat. This will ensure that the steak is well seasoned and flavorful.

2. Cook the flank steak over high heat

To achieve a perfectly cooked flank steak, cook it over high heat for approximately 5 minutes per side, or until it reaches medium doneness. Cooking the steak at high heat will help to sear the meat and create a nice crust on the outside.

3. Let the steak rest before slicing

After cooking, let the flank steak rest for at least 5 minutes before slicing it. This will allow the juices to redistribute throughout the meat, resulting in a juicy and tender steak.

4. Toast the pearl onions

When preparing the pearl onions, try toasting them in a skillet with olive oil until they are brown and caramelized. This will add depth of flavor to the dish.

5. Add mushrooms to the pan

When cooking the mushrooms, consider adding them to the same pan where you cooked the steak, using some of its juices for extra flavor.

By following these tips, you’ll be able to prepare an impressive meal that’s sure to impress your family and friends!


As a sommelier, I have come across multiple questions regarding the perfect pairing of wine and food. In the case of the Flank Steak with Merlot Mushrooms and Pearl Onions recipe, one might wonder what type of red wine would be suitable. The following section provides answers to some frequently asked questions that will help you make the most out of this recipe.

How do you cook flank steak so it’s not tough?

For best results, high heat and a short cooking period are recommended for cooking these steaks. To achieve the optimal texture and taste, it is advised to use cooking spray or olive oil and cook each side of the steak for approximately four minutes. Keeping the meat at a medium rare temperature will prevent it from becoming too tough.

What type of mushroom is best for steak?

When it comes to matching mushrooms with steak, cremini mushrooms are the ideal choice. These mushrooms are also called baby bellas and are widely popular for their earthy flavor and tender texture. Additionally, other types of mushrooms like white button mushrooms and shiitake mushrooms also pair well with steak.

What is the recommended cooking method for flank steak?

There are various ways to cook Flank steak, including grilling, pan-searing in a skillet, broiling in the oven, or using an instant pot. The key is to minimize the grilling time for Flank steak.

How do you tenderize flank meat?

One way to make flank steak more tender is by using a marinade with an acidic component like vinegar or citrus. Chemical reactions caused by the acid break down the tough muscle fibers in the flank steak, resulting in a more tender texture. This process also adds plenty of delicious flavors to the meat.
