Follow these simple steps to create an amazing steak and mashed potatoes meal effortlessly:

1. Prepare the Potatoes: Peel and cut the potatoes into even-sized chunks. Place them in a large pot of salted water.

2. Boil Potatoes: Bring the pot to a boil over high heat. Cook for about 15-20 minutes, or until tender when pierced with a fork.

3. Drain and Mash: Once they’re cooked, drain the potatoes and return them to the pot. Add butter, milk, sour cream (if using), and garlic. Mash until smooth, seasoning with salt and pepper to taste.

4. Prepare the Steak: While the potatoes are cooking, take the steaks out of the refrigerator. Allow them to sit at room temperature for about 15 minutes.

5. Season the Steaks: Generously season both sides with salt and freshly ground black pepper.

6. Cook the Steaks: Heat olive oil or butter in a cast-iron skillet or grill pan over medium-high heat.

7. Sear the Steaks: Add the steaks to the hot skillet and sear for about 4-5 minutes on one side. Flip and cook for another 3-4 minutes for medium-rare. Adjust cooking time for your desired doneness.

8. Rest the Steaks: Once cooked to your preference, remove the steaks from the skillet and let them rest on a plate for 5-10 minutes.

9. Serve Potatoes: While the steaks rest, give the mashed potatoes a stir. Make sure they are creamy and well-seasoned.

10. Plate and Garnish: Slice the steak against the grain for tenderness and plate alongside the creamy mashed potatoes. Garnish with freshly chopped chives or parsley if desired.

These straightforward steps will guide you through creating a delightful steak and mashed potatoes dish that is sure to impress.
