01 - Combine steak cubes with olive oil, salt, black pepper, and smoked paprika in a mixing bowl. Toss thoroughly to evenly coat and set aside to marinate while preparing 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 brown and tender, about 12 to 15 minutes. Transfer potatoes to a plate and keep warm.
03 - Increase skillet heat to high. Arrange steak bites in a single layer in the pan, working in batches if crowding. Sear undisturbed for 2 minutes, then turn and continue cooking for an additional 2 to 3 minutes until caramelized and cooked to desired doneness. Remove steak bites and set aside.
04 - Reduce heat to medium and add unsalted butter to the pan. Once melted, add minced garlic and dried thyme, sautéing for 30 seconds until aromatic.
05 - Return cooked potatoes and steak bites to the skillet. Toss to coat all ingredients in the garlic butter and heat through, about 1 to 2 minutes.
06 - Sprinkle chopped fresh parsley over the skillet before serving.
