Instructions

Cooking the Mushrooms and Onions

Set the stove to medium heat and add butter to a large skillet.
1 Tablespoon butter
Once the butter has melted, add sliced mushrooms and a pinch of salt and pepper.
8 ounces cremini mushrooms, ¼ teaspoon salt and pepper
Sauté the mushrooms for 1-2 minutes, stirring often.
Then, add garlic and onions to the skillet with the sauteed mushrooms and continue to sauté for another 2-3 minutes.
2 cloves garlic, ½ small onion

Making the Cognac Sauce (Optional)

Take the skillet off the heat and add Cognac to it.
¼ cup Cognac
Once you've added the Cognac, return the skillet to the heat. Be cautious, as it might flare up!
Sauté for 1-2 minutes to let the alcohol cook off, then mix in Dijon mustard, Worcestershire sauce, and beef broth.
1 Tablespoon Dijon mustard, 1 Tablespoon Worcestershire sauce, ½ cup beef broth
Stir the mixture, then pour heavy whipping cream into the skillet. Stir as you pour, and pour slowly, to keep it from curdling.
¼ cup heavy whipping cream
Keep stirring and let it cook for 5 minutes until the sauce becomes thicker.
Serve this amazing sauce over your favorite steak recipe and enjoy!

Notes

If you want to make steakhouse mushrooms without the cognac sauce, simply follow the instructions to saute them with the garlic, onions, and seasoning. I also recommend adding the Worcestershire sauce for a bit of extra flavor and tenderness.
