01 - Combine steak cubes with olive oil, salt, black pepper, and smoked paprika in a mixing bowl. Set aside to marinate while preparing other ingredients.
02 - Heat 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 brown and tender, about 12 to 15 minutes. Transfer potatoes to a plate and keep warm.
03 - Increase skillet heat to high. Add steak cubes in a single layer, working in batches if necessary. Sear undisturbed for 2 minutes, turn, and cook for an additional 2 to 3 minutes until browned to preferred doneness. Remove steak and set aside.
04 - Reduce heat to medium. Add butter to the skillet, allow to melt, then add minced garlic and dried thyme. Sauté for 30 seconds until fragrant.
05 - Return potatoes and steak bites to the skillet. Toss with the garlic butter until evenly coated and heated through, about 1 to 2 minutes.
06 - Sprinkle chopped fresh parsley evenly over the dish before serving.
