Ingredients

Instructions

  1. Step 1: Preheat oven to 400°F. Wrap 4 garlic cloves in foil with 1 tbsp olive oil and roast for 30 minutes until soft and golden.
  2. Step 2: Peel and chop 1.5 lbs russet potatoes into 1.5-inch cubes. Place in a pot of cold salted water, bring to a boil, and cook for 15-20 minutes until fork-tender.
  3. Step 3: While potatoes cook, pat dry 12 oz ribeye steak. Season both sides with 1 tsp salt and 1/2 tsp black pepper.
  4. Step 4: Heat 1 tbsp olive oil in a heavy skillet over medium-high heat. Add ribeye and sear for 4 minutes per side for medium-rare, adjusting time for preferred doneness.
  5. Step 5: Reduce heat to medium-low and add 3 tbsp butter and 2 minced garlic cloves to the pan. Spoon melted garlic butter over steak for 1 minute, then remove steak to rest.
  6. Step 6: Drain potatoes and mash with roasted garlic cloves, 1/4 cup heavy cream, 1/4 cup whole milk, and 1 tbsp chopped fresh parsley until smooth and creamy.
  7. Step 7: Serve the rested ribeye topped with garlic butter alongside the roasted garlic mashed potatoes.
