Instructions

1. Step 1: Preheat oven to 400°F. Slice the top off 1 whole garlic bulb to expose cloves, drizzle with 1 tbsp olive oil, wrap in foil, and roast for 35 minutes until soft and caramelized.
2. Step 2: While garlic roasts, season 16 oz ribeye steak generously with 1 tsp salt and 1 tsp black pepper on both sides. Heat 2 tbsp olive oil in a cast-iron skillet over medium-high heat until shimmering.
3. Step 3: Sear ribeye in hot skillet for 4 minutes per side for medium-rare, spooning pan juices over steak as it cooks. Remove steak to rest on a plate.
4. Step 4: In the same skillet, melt 4 tbsp unsalted butter with 4 minced garlic cloves and 1 tbsp chopped fresh parsley over low heat until fragrant, about 1 minute. Remove from heat.
5. Step 5: Boil 2 lbs peeled quartered russet potatoes in salted water (1 tsp salt) for 15-20 minutes until fork-tender. Drain well.
6. Step 6: Squeeze soft roasted garlic cloves from bulb into drained potatoes. Add 1/2 cup heavy cream and 3 tbsp salted butter; mash until smooth and creamy.
7. Step 7: Slice rested ribeye and serve topped with garlic herb butter alongside roasted garlic mashed potatoes.
