Ingredients For Garlic Butter Steak and Potatoes

For the Mashed Potatoes:

• Russet or Yukon Gold potatoes: 2 lbs (peeled and cubed)

• Unsalted butter: 1/2 cup (melted)

• Heavy cream: 1/2 cup (warmed)

• Garlic powder: 1 tsp

• Salt and black pepper: To taste

• Fresh parsley: 2 tbsp (finely chopped for garnish)

For the Garlic Butter Steak:

• Ribeye or New York Strip steaks: 2 thick-cut steaks (about 12 oz each)

• Olive oil: 1 tbsp (high smoke point)

• Butter: 3 tbsp (divided)

• Garlic: 4 cloves (smashed)

• Fresh rosemary or thyme: 2 sprigs

• Coarse sea salt and cracked black pepper: To taste

Step-by-Step Instructions

Step 1: Prepare the Creamy Mashed Potatoes

1. Place the cubed potatoes in a large pot and cover them with cold, salted water.

2. Bring to a boil over high heat, then reduce to a simmer. Cook for 15–20 minutes until the potatoes are fork-tender.

3. Drain the water completely. Return the potatoes to the warm pot for 1 minute to evaporate excess moisture.

4. Mash the potatoes using a potato masher or ricer. Slowly fold in the melted butter, warmed heavy cream, garlic powder, salt, and pepper until perfectly smooth. Cover to keep warm.

Step 2: Sear the Garlic Butter Steak

1. Pro Tip: Take your steaks out of the fridge 30 minutes before cooking to bring them to room temperature. Pat them completely dry with a paper towel.

2. Season both sides generously with coarse sea salt and cracked black pepper.

3. Heat olive oil in a heavy cast-iron skillet over high heat until it just begins to smoke.

4. Carefully place the steaks in the skillet. Sear for 2–3 minutes without moving them to develop a deep, golden crust. Flip and sear the other side for another 2 minutes.

5. Turn the heat down to medium. Add the 3 tablespoons of butter, smashed garlic cloves, and fresh herbs to the pan.

6. Tilt the skillet slightly and use a large spoon to continuously baste the melted garlic butter over the steaks for another 1–2 minutes until your desired doneness is reached (135°F / 57°C for medium-rare).

Step 3: Rest and Serve

1. Remove the steaks from the skillet and let them rest on a cutting board for 5–7 minutes to lock in the juices.

2. Plate a generous scoop of the creamy mashed potatoes, making a small well in the center to pool a little extra melted butter.

3. Place the rested steak alongside the potatoes, top with a slice of garlic herb butter, and garnish everything with fresh chopped parsley.

Chef’s Tips for the Perfect Steak

Always Rest Your Meat: Cutting into a steak immediately causes all the flavorful juices to run out onto the board. Letting it rest allows the muscle fibers to relax and reabsorb those juices.

Use High Heat: A cold pan will boil your steak instead of searing it. Make sure your cast-iron skillet is piping hot before the meat hits the surface.
