01 - Combine steak cubes with olive oil, salt, black pepper, and smoked paprika in a mixing bowl. Toss well and allow to marinate while you prepare the 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, until golden and fork-tender—about 12 to 15 minutes. Transfer the potatoes to a plate and keep warm.
03 - Raise skillet heat to high. Arrange marinated steak bites in a single layer, working in batches if necessary. Sear without moving for 2 minutes, then flip and cook for an additional 2 to 3 minutes until browned to your preferred level. Remove steak bites and reserve.
04 - Reduce heat to medium and add butter to the pan. Once melted, stir in minced garlic and dried thyme, sautéing 30 seconds until fragrant.
05 - Return cooked potatoes and steak bites to the skillet. Toss in the garlic butter until evenly coated and heated through, about 1 to 2 minutes.
06 - Sprinkle with chopped fresh parsley and serve immediately.
