Ingredients
  

For the steak

  • 2 pieces ribeye or filet mignon steaks about 1 inch thick
  • Salt and pepper to taste
  • 1 tbsp olive oil
  • 1 tbsp butter

For the mushroom sauce

  • 2 tbsp butter for the sauce
  • 2 cups sliced mushrooms (cremini or button)
  • 1 clove garlic, minced
  • 1/2 cup beef broth
  • 1/4 cup heavy cream
  • Fresh chives, chopped for garnish

For the creamy mashed potatoes

  • 4 large potatoes, peeled and cubed
  • 1/2 cup milk
  • 3 tbsp butter for the mashed potatoes
  • Salt and pepper to taste

Instructions
 

Cooking the Steak

  • Season the steaks with salt and pepper on both sides.
  • Heat olive oil and 1 tablespoon of butter in a skillet over medium-high heat.
  • Cook the steaks for about 4-5 minutes on each side for medium-rare, or until they reach your desired doneness.
  • Remove and let them rest.

Making the Mushroom Sauce

  • In the same skillet, add 2 tablespoons of butter and sauté the sliced mushrooms until they are browned, about 5-7 minutes.
  • Add the minced garlic and cook for another minute.
  • Pour in the beef broth and let it simmer for a few minutes until it reduces.
  • Stir in the heavy cream and season with salt and pepper.
  • Let the sauce simmer until it thickens slightly.

Preparing the Mashed Potatoes

  • Boil the cubed potatoes in salted water until they are tender.
  • Drain and return them to the pot.
  • Add milk, 3 tablespoons of butter, salt, and pepper.
  • Mash the potatoes until they are smooth and creamy.

Serving

  • Serve the steak topped with the mushroom sauce alongside the creamy mashed potatoes, garnished with fresh chives.

Notes

For a more flavorful steak, try marinating it for a couple of hours before cooking. Use a meat thermometer to check for doneness: 130°F for medium-rare, 145°F for medium. If you like your mashed potatoes extra creamy, add more milk or butter during mashing. Store leftovers in airtight containers in the refrigerator for 3-4 days, or freeze for up to 2 months.
