Combine salt, garlic powder, onion powder, Italian seasoning, and paprika in a small mixing bowl, then divide this blend equally into two separate portions. Set aside.

In another bowl, thoroughly mix the softened butter with minced garlic and chopped parsley to create a flavorful compound butter. Set aside.

Place the cubed steak into a large bowl and drizzle with Worcestershire sauce and optional browning sauce. Add one half of the spice blend and toss until the meat is uniformly coated.

Boil the cubed potatoes in salted water for 5–6 minutes until they are just beginning to soften. Drain and allow them to cool slightly. Once cooled, season the potatoes with the remaining half of the spice mixture and 1 tablespoon of olive oil. Stir to coat evenly.

Heat the remaining tablespoon of olive oil in a large skillet over medium-high heat. Once hot, add the steak cubes and sear for 5 to 7 minutes until evenly browned. Remove from the skillet and set aside.

In the same pan, add the pre-cooked potatoes and sauté over medium-high heat for 10 to 15 minutes, stirring occasionally, until they are crisped and fork-tender.

Return the steak to the pan with the potatoes. Add the prepared garlic herb butter and stir thoroughly, allowing the mixture to coat all components generously.

Garnish with fresh parsley and a pinch of red pepper flakes before serving.
