01 - Combine steak cubes with olive oil, salt, black pepper, and smoked paprika in a mixing bowl. Allow to marinate while preparing the potatoes.
02 - Heat 1 tablespoon olive oil in a large skillet over medium-high heat. Add quartered potatoes, season with salt and black pepper, and cook, stirring occasionally, until golden and fork-tender, about 12 to 15 minutes. Transfer potatoes to a plate and keep warm.
03 - In the same skillet, increase heat to high. Place steak cubes in a single layer, working in batches to avoid overcrowding. Sear undisturbed for 2 minutes, then turn and cook an additional 2 to 3 minutes, or until browned to your preferred doneness. Set steak bites aside.
04 - Reduce heat to medium. Add unsalted butter to the skillet and allow to melt. Stir in minced garlic and dried thyme; sauté for 30 seconds until fragrant.
05 - Return cooked potatoes and steak bites to the skillet. Toss with garlic butter until evenly coated and heated through, 1 to 2 minutes.
06 - Sprinkle with freshly chopped parsley just before serving.
