Ingredients
1 tablespoon olive oil for searing and adding high smoke point cooking fat
4 tablespoons unsalted butter for rich flavor and browning
1 pound Yukon Gold potatoes for crisp texture while staying tender
4 cloves garlic for savory aroma and depth
1 teaspoon dried rosemary for pairing well with beef and potatoes
1 teaspoon dried oregano for herbal balance and Mediterranean note
1/2 teaspoon kosher salt for seasoning
1/2 teaspoon ground pepper for mild heat and seasoning
1 1/2 pounds sirloin steak for rich, beefy flavor and tenderness
Freshly chopped parsley for garnish
Instructions
1-First Step: Mise en place and prep (10 minutes)
* Pat the steak cubes dry with paper towels and season lightly with 1/4 teaspoon kosher salt and a pinch of pepper. Dry meat sears better.
* Wash and dice 1 pound Yukon Gold potatoes into uniform 1/2-inch cubes so they cook evenly.
* Peel and mince 4 cloves garlic, and measure out dried rosemary and oregano.
* Have a heavy cast iron skillet and a spatula or tongs ready; set the stove to medium-high heat.
2-Second Step: Heat the skillet
Place a cast iron skillet over medium-high heat. Add 1 tablespoon olive oil and 2 tablespoons unsalted butter; allow butter to fully melt and the pan to get hot until it shimmers but does not smoke. This creates a hot surface for browning both potatoes and steak.
3-Third Step: Cook the potatoes
1. Add the diced potatoes to the hot skillet along with the minced garlic, 1 teaspoon dried rosemary, 1 teaspoon dried oregano, 1/2 teaspoon kosher salt, and 1/2 teaspoon ground pepper.
2. Cook the potatoes about 4 minutes without stirring. This initial sear helps create crisp edges. After 4 minutes, stir and continue cooking another 3 to 4 minutes until potatoes are fork tender and golden brown.
3. If potatoes brown too quickly but remain firm, reduce heat to medium-low, add 2 tablespoons warm water, cover the pan, and cook 3 to 4 minutes to finish (see tips section for more detail).
4. Remove the potatoes from the pan and set them aside on a plate while you cook the steak.
4-Fourth Step: Sear the steak
Increase heat to high and add the remaining 2 tablespoons unsalted butter to the skillet. Let it melt fully and come to temperature. Add steak cubes in a single layer without crowding the pan. Sear for 1 minute, then flip or stir and cook for another 1 to 2 minutes or until steak reaches your desired doneness. Use a meat thermometer to be precise: 125-130°F rare, 130-140°F medium-rare, 140-150°F medium, 150-160°F medium-well, and 160-165°F well-done. Remove the skillet from heat immediately once target temp is reached; carryover will raise the temp slightly.
5-Fifth Step: Combine and finish
1. Return the cooked potatoes to the skillet and toss gently with the steak to combine flavors and coat everything in the garlic butter.
2. Taste and add additional salt or pepper if needed. Garnish with freshly chopped parsley if you like.
3. Serve immediately while hot so the potatoes stay crisp and the steak bites remain juicy.
Notes
🥩 Use a meat thermometer for perfect steak doneness: rare (125-130°F), medium-rare (130-140°F), medium (140-150°F)
🥔 Don’t crowd the pan to ensure proper searing and prevent steaming instead of browning
🍳 Add 2 tablespoons warm water and cover if potatoes need more time to tenderize without burning
