Sliced Sirloin Steak & Sides

Method

Cooking Instructions

  1. 1

    Prepare the Mashed Potatoes

    In a large pot, add the diced potatoes and cover with water. Bring to a boil and cook until tender, about 15-20 minutes. Drain and return potatoes to the pot.

  2. 2

    Mash the Potatoes

    Add butter, milk, and minced garlic to the potatoes. Mash until smooth and creamy. Season with salt and pepper to taste. Set aside.

  3. 3

    Cook the Steak

    Season the sirloin steak with salt and black pepper. In a skillet, heat olive oil over medium-high heat. Add the steak and sear for 4-5 minutes on each side for medium-rare, or until desired doneness. Remove from skillet and let rest.

  4. 4

    Make the Cabernet Mushroom Sauce

    In the same skillet, add sliced mushrooms and cook until browned, about 5 minutes. Pour in Cabernet wine and beef broth, scraping the bottom of the pan to deglaze. Simmer until sauce thickens, about 10 minutes.

  5. 5

    Slice and Serve

    Slice the rested steak and serve with a generous spoonful of mushroom sauce over the top. Plate with garlic mashed potatoes on the side.
