1-First Step: Prepare Your Ingredients Begin by dicing 1 pound of Yukon Gold potatoes into ½-inch cubes and cutting 1½ pounds of sirloin steak into 1-inch cubes. Mince 4 cloves of garlic and measure out your herbs and seasonings, like 1 teaspoon dried rosemary and 1 teaspoon dried oregano. This mise en place takes about 10 minutes and helps everything flow smoothly.

2-Second Step: Cook the Potatoes Heat a cast iron skillet over medium-high heat and add 1 tablespoon olive oil along with 2 tablespoons unsalted butter. Let the butter melt completely, which should take just a minute. Add the diced potatoes, minced garlic, rosemary, oregano, ½ teaspoon kosher salt, and ½ teaspoon ground pepper to the skillet.

3-Third Step: Let the Potatoes Brown Cook the potatoes for about 4 minutes without stirring to get a nice golden crust. Then, stir them and continue cooking for another 3-4 minutes until they’re fork tender. Once done, remove the potatoes from the pan and set them aside, which takes around 7-8 minutes total.

4-Fourth Step: Sear the Steak Increase the skillet heat to high and add the remaining 2 tablespoons of unsalted butter, letting it melt. Place the steak bites in a single layer in the skillet and cook for 1 minute. Flip or stir the bites and cook for 1-2 more minutes to your preferred doneness, aiming for internal temperatures like 130-140°F for medium-rare.

5-Fifth Step: Combine and Finish Return the cooked potatoes to the skillet and toss everything together with the steak. Adjust the seasoning with a bit more salt and pepper if needed, then garnish with freshly chopped parsley for a pop of color. This final step takes just a minute and makes the dish ready to serve immediately.
