# What You’ll Need:

→ Steak & Marinade

01 - 1.5 lbs sirloin steak, cut into 1-inch cubes
02 - 1 tablespoon olive oil
03 - 1 teaspoon salt
04 - 0.5 teaspoon freshly ground black pepper
05 - 0.5 teaspoon smoked paprika

→ Potatoes

06 - 1.5 lbs baby Yukon gold potatoes, quartered
07 - 2 tablespoons olive oil
08 - 0.5 teaspoon salt
09 - 0.5 teaspoon dried thyme
10 - 0.25 teaspoon ground black pepper

→ Garlic Butter Sauce

11 - 4 tablespoons unsalted butter
12 - 6 cloves garlic, minced
13 - 1 tablespoon fresh rosemary, finely chopped
14 - 1 tablespoon fresh parsley, chopped
15 - 0.5 teaspoon crushed red pepper flakes
16 - Juice of 0.5 lemon

# Directions:

01 - In a large bowl, combine steak cubes with olive oil, salt, pepper, and smoked paprika. Toss until evenly coated and set aside while preparing potatoes.
02 - Heat 2 tablespoons olive oil in a large skillet over medium-high heat. Add quartered potatoes, salt, thyme, and black pepper. Cook while stirring occasionally for 15-18 minutes until golden and fork-tender. Transfer to a plate and cover with foil to retain warmth.
03 - Increase skillet heat to high. Add marinated steak cubes in a single layer, working in batches if needed. Sear for 2-3 minutes per side until browned and cooked through. Remove from skillet and set aside.
04 - Reduce heat to medium and add butter to the skillet. Once melted, stir in minced garlic, rosemary, parsley, and red pepper flakes. Sauté for approximately 1 minute until fragrant.
05 - Return cooked potatoes and seared steak to the skillet. Toss all components to coat thoroughly with garlic butter sauce. Drizzle with lemon juice and adjust seasoning to taste.
06 - Transfer to serving dish and garnish generously with additional chopped fresh parsley. Serve immediately while hot.

# Expert Tips:

01 -
  • The whole thing comes together in under 45 minutes, which means you can have restaurant-quality flavors on a weeknight without the guilt of ordering out.
  • Those crispy potato edges against the tender steak bites in silky garlic butter is genuinely addictive, and your cast iron will develop more seasoning in the process.
02 -
  • Don't skip letting the steak cubes rest after seasoning—even five minutes helps the marinade adhere instead of sliding off in the pan.
  • The garlic can burn in about a second if your heat is too high after adding the butter, so drop it to medium and stay present; burned garlic tastes bitter and ruins the whole sauce.
03 -
  • Pat your steak cubes dry with a paper towel before seasoning—moisture is the enemy of a good sear, and that's the difference between steamed and caramelized.
  • Don't move the potatoes around too much while they cook; let them sit for a couple minutes between stirs so they can actually brown instead of just rolling around.
