Savory steak bites and crispy Yukon gold potatoes coated in rich garlic butter sauce.

# 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

# How to Make It:

01 - In a large bowl, combine steak cubes with olive oil, salt, pepper, and smoked paprika. Toss until evenly coated and allow to marinate while preparing potatoes.
02 - Heat 2 tablespoons olive oil in a large cast iron skillet over medium-high heat. Add quartered potatoes, salt, thyme, and black pepper. Cook, stirring occasionally, until golden and fork-tender, approximately 15 to 18 minutes. Transfer to a plate and keep warm under foil.
03 - Return skillet to high heat. Add marinated steak cubes in a single layer, working in batches if needed. Sear for 2 to 3 minutes per side until browned and cooked through. Remove and set aside.
04 - Reduce heat to medium. Add butter to the skillet and allow to melt. Stir in minced garlic, rosemary, parsley, and red pepper flakes. Sauté until fragrant, approximately 1 minute.
05 - Return potatoes and steak bites to the skillet. Toss to coat thoroughly in the garlic butter sauce. Drizzle with lemon juice and adjust seasonings to taste. Garnish with additional fresh parsley and serve immediately.

# Expert Advice:

01 -
  • Ready in 40 minutes from counter to table, so it actually fits into a real weeknight without stress.
  • Cast iron does the heavy lifting here—one pan means less cleanup and somehow everything tastes better.
  • That garlic butter sauce is the real star; it transforms simple potatoes and steak into something you'd order at a restaurant.
02 -
  • Don't skip the searing step or move the steak around too much in the pan—those browned, crusty edges are where the flavor hides.
  • If your potatoes and steak finish at different times, that's okay; tent the finished one with foil and it'll stay warm enough while you finish the other.
03 -
  • Cut your potatoes the same size so they finish cooking at the same time; uneven pieces lead to some burnt edges and some undercooked centers.
  • Let your skillet get properly hot before adding the steak—a hesitant sear wastes your effort and steams the meat instead of browning it.
