Steak and Mushrooms will never go out of style! This dish has such a luxurious feel, making it perfect for entertaining. But don't worry, this recipe is easy enough to maintain a casual vibe.) It works well with a side of crockpot mashed potatoes, bread machine dinner rolls, or a simple green salad with some peppery arugula. Leftovers - if you have any - are fabulous in a wrap or bowl with blue cheese.

Ingredients Needed

Red Wine: When making red wine marinated steak, use a wine that you would drink. (But no need to go for the expensive stuff.)
Thyme: If you can't find thyme, look for other fresh herbs. Rosemary is a great option.
Garlic: Freshly minced garlic is best here.
Red Pepper Flakes: For a touch more heat, you can use ¼ to ½ teaspoon of cayenne pepper.
Salt and Pepper: I recommend a teaspoon of salt and ½ teaspoon of black pepper.
Steak: Use your favorite cut! New York strip, tenderloin, porterhouse, and ribeye are all great options for this recipe.
Onion: White or yellow onion work best.
Mushrooms: You can use any type of mushroom you like. (I like baby Bellas or shiitake mushrooms when I can find them.) For entertainment, I will often buy a gourmet blend. Buying sliced mushrooms is a great way to save time.
White Wine: This adds a nice pop of flavor to the mushrooms, but feel free to omit. Beef broth would be a good alternative.

Tips & Tricks for Making Grilled Steak with Mushrooms

If you have the time, salt the steaks for up to two days before marinating them on a wire rack set on a baking sheet. The salt will work its way into the meat, seasoning and breaking down muscle proteins. Not only will the steak be more tender and flavorful, but it will also be juicier.
Pull the steak out of the refrigerator at least 30 minutes before cooking to let them temper.
Don't skip resting the steak before cutting! If you cut the steak while it is still too warm, it will lose a lot of juice.
If you prefer a mushroom gravy, add 1 cup of good quality beef broth to the mushrooms and thicken it with ¼ - ½ teaspoons of xanthan gum or 1 tablespoon of cornstarch mixed with 2 tablespoons of broth.
For even more flavor, top your steak with compound butter.
