Prepare Your Ingredients:

• Let the steak rest at room temperature for 30 minutes.
• Peel and chop potatoes into equal-sized chunks. Place them in a pot of cold, salted water.

Cook the Mashed Potatoes:

• Bring the pot of potatoes to a boil, then reduce heat to simmer for 15-20 minutes until fork-tender.
• Drain potatoes and allow them to rest briefly.

Mash the Potatoes:

• Return the potatoes to the pot. Add butter and warmed cream or milk.
• Mash until smooth, gradually seasoning with salt and pepper.
• Add optional ingredients like roasted garlic or Parmesan for enhanced flavor.

Cook the Steak:

• Season the steak generously with salt and pepper.
• Heat a cast-iron skillet over high heat, adding a tablespoon of olive oil.
• Sear the steak for 2-3 minutes on each side until golden-brown.

Baste and Rest:

• Reduce heat, then add butter, smashed garlic, and fresh herbs to the skillet.
• Baste the steak with the melted butter for enhanced flavor.
• Use a meat thermometer to check doneness (e.g., 130°F for medium-rare). Remove the steak from heat and let it rest for 5-10 minutes.

Serve and Garnish:

• Plate the mashed potatoes alongside the steak.
• Drizzle pan juices or sauce over the steak and garnish with fresh herbs like parsley or chives.
