Instructions

Prep work: Sprinkle ¼ tsp. salt and pepper on both sides of two 8 oz., 1-inch thick steaks. Allow the steaks to sit at room temperature for 15 minutes. Mince 2 cloves of garlic and ½ a small onion. Clean 8 oz. cremini mushrooms and cut into slices.
Heat a large cast iron skillet to medium-high and add 1 Tbsp. vegetable oil. Once hot, add the steaks and sear for 4-8 minutes on the first side to form a brown crust. Flip and sear for another 4-8 minutes on the opposite side.
Once cooked, remove the steaks and place on a plate covered with foil.
Reduce heat to medium and add 1 Tbsp. butter. Once melted, add sliced mushrooms and a pinch of salt and pepper. Saute for 1-2 minutes, stirring frequently.
Add the garlic and onions to the skillet and saute for another 2-3 minutes.
Remove the skillet from heat and add ¼ cup Cognac to the pan. Return to the heat once added - be careful as it may flare up. Saute for 1-2 minutes to allow the alcohol to cook down, then add 1 Tbsp. Dijon mustard, 1 Tbsp. Worcestershire sauce, and ½ cup beef broth. Stir.
Add ¼ cup heavy whipping cream to the skillet. Stir and allow to cook for 5 minutes until the sauce thickens. Then, return the steaks along with any juices on the plate to the pan and cook for another 2 minutes or so.
Slice, serve, and enjoy! We like to garnish with chopped chives or parsley.

Notes

The best steaks to use for this recipe are flat iron, strip, or beef tenderloin. You won't need to tenderize the steak beforehand.
Cooking time varies based on the thickness of your steaks. Make sure to use steaks that are 1 inch thick or less. This makes them easy and quick to cook.
