Preheat the Blackstone grill over high heat to approximately 205°C.

Place diced potatoes in one bowl and diced steak in a separate bowl. Pour 2.5 ml oil into each bowl. Add half of the garlic powder, salt, and black pepper to each bowl and toss separately to evenly coat.
03 -
Spread the remaining oil directly onto the hot grill and use a spatula to evenly distribute.

Arrange the potatoes on the grill in a single layer. Drizzle some water over the potatoes and cover with a dome or grill lid. Cook for 4–5 minutes, then toss the potatoes, add more water, cover, and cook for an additional 4–5 minutes. Repeat until potatoes are fork-tender.
05 -
Add the diced steak to the grill. Sear undisturbed for 2–3 minutes to achieve browning, then toss and cook for another 2–3 minutes or until desired doneness.
06 -
Remove the lid from the potatoes. Add butter between the steak and potatoes on the grill. Allow it to melt slightly, then toss steak and potatoes together to coat in the butter.
