Ingredients

browned butter mashed potatoes

  • 1/2 cup unsalted butter
  • 2 large russet potatoes (about 1 pound), peeled and chopped
  • 1/2 cup heavy cream
  • 1 minced garlic clove
  • salt and pepper to taste

steak

  • 12 ounce boneless prime ribeye steak
  • 3 1/2 tablespoons unsalted butter
  • 1 tablespoon avocado oil
  • 2 lightly smashed garlic cloves
  • 2 to 3 sprigs of thyme
  • salt and pepper to taste

Instructions

mashed potatoes

  • Place chopped potatoes into a pot and fill with water. Place over high heat and boil until potato is fork tender. Drain into a colander, then place potatoes back into pot.
  • Place butter in a small saucepan and melt over medium heat. Continue to cook until butter bits at the bottom of the pan have browned and omit a nutty aroma.
  • Remove from heat and reserve 3 tablespoons of browned butter. Pour remaining butter over potatoes, scraping out as much of the browned bits as possible.
  • Season potatoes with a generous amount of salt and pepper and mash with a potato masher. While potatoes are still lumpy add warm cream and continue to mash until smooth.
  • Add more salt and pepper as needed. Cover to keep warm and set aside.

pan seared ribeye

  • Preheat oven to 400˚F.
  • Place a large skillet over high heat. Generously season steak with salt and pepper.
  • Melt 1 1/2 tablespoons butter and oil into skillet. Add garlic clove and thyme and cook for about 1 minute.
  • Add steak to skillet and sear on each side for about 3 minutes.
  • Place skillet in the oven and cook for 3 to 5 minutes, depending on desired doneness (3 minutes for medium rare and 5 minutes for medium to medium-well)
  • Remove skillet from oven and add remaining butter. Slightly tilt skillet so butter, garlic, and thyme pile into bottom. For the next 1 to 2 minutes, spoon hot, melted butter over steak, fully basting entire steak. Remove from oven and transfer to a cutting board.
  • To serve: Pile mashed potatoes onto a platter and drizzle with remaining browned butter. Season with salt and pepper.
  • Top with steak. Spoon some of the basting mixture over steak and serve.
