01 - Combine steak cubes with olive oil, salt, black pepper, and smoked paprika in a mixing bowl. Toss thoroughly and let rest while preparing potatoes.
02 - Heat olive oil in a large skillet over medium-high heat. Add quartered baby potatoes, season with salt and black pepper, and cook, stirring occasionally, for 12 to 15 minutes until potatoes are golden and fork-tender. Transfer potatoes to a plate and keep warm.
03 - Increase skillet heat to high. Arrange marinated steak bites in a single layer, working in batches if necessary. Sear without moving for 2 minutes, then turn and continue cooking for another 2 to 3 minutes to brown on all sides or until desired doneness. Remove steak from skillet and set aside.
04 - Reduce heat to medium. Melt unsalted butter in the same skillet. Add minced garlic and dried thyme, sautéing for 30 seconds until aromatic.
05 - Return cooked potatoes and steak bites to the skillet. Toss ingredients to coat evenly in garlic butter and warm through for 1 to 2 minutes.
06 - Sprinkle with chopped fresh parsley just before serving.
