Method

For the Flat Iron Steak

  1. 1

    Prepare the Steak

    Take the flat iron steak out of the refrigerator and let it come to room temperature for about 30 minutes before cooking.

  2. 2

    Season the Steak

    Rub the steak with olive oil, then sprinkle garlic powder, salt, and black pepper evenly on both sides.

  3. 3

    Cook the Steak

    Heat a grill or skillet over medium-high heat. Place the steak on the grill and cook for 5-7 minutes on each side for medium-rare, or longer to reach your desired doneness.

  4. 4

    Rest the Steak

    Remove the steak from the heat and let it rest for 5 minutes before slicing.

For the Buttermilk Mashed Potatoes

  1. 5

    Boil the Potatoes

    Peel and cut the Yukon gold potatoes into quarters. Place them in a large pot, cover with water, add salt, and bring to a boil. Cook until tender, about 15-20 minutes.

  2. 6

    Mash the Potatoes

    Drain the potatoes and return them to the pot. Add buttermilk and butter, then mash until smooth and creamy. Season with salt and black pepper to taste.

For the Parmesan Asparagus

  1. 7

    Prepare the Asparagus

    Preheat the oven to 400°F (200°C). Trim the woody ends off the asparagus.

  2. 8

    Season and Roast

    Place the asparagus on a baking sheet, drizzle with olive oil, sprinkle with salt, and toss to coat. Roast in the oven for 10-12 minutes until tender.

  3. 9

    Add Parmesan

    Remove the asparagus from the oven, sprinkle grated Parmesan cheese over the top, and return to the oven for an additional 2-3 minutes until the cheese is melted.

For the House Steak Sauce

  1. 10

    Mix the Sauce

    In a bowl, combine ketchup, Worcestershire sauce, apple cider vinegar, garlic powder, and honey. Mix well until smooth.

  2. 11

    Season to Taste

    Taste the sauce and add salt as needed. Adjust the flavors according to your preference.
