In a large bowl, toss the diced Yukon Gold potatoes with olive oil, salt, and black pepper until evenly coated.
Preheat the oven to 425°F (220°C). Spread the seasoned potatoes on a baking sheet in a single layer and roast for 20-25 minutes or until they start to turn golden brown and are tender. Stir halfway through for even cooking.
While the potatoes are roasting, season the ribeye steaks liberally with salt and black pepper on both sides. Let them sit at room temperature for about 15 minutes.
In a large skillet or cast-iron pan over medium-high heat, melt 2 tablespoons of butter. Once melted and bubbling, add the steaks to the pan. Sear for 4-5 minutes on each side (for medium-rare), depending on your preferred doneness.
In the last minute of cooking, add the minced garlic, remaining butter, rosemary, and thyme to the skillet. Use a spoon to baste the steaks with the melting garlic butter for extra flavor.
Remove the steaks from the pan and let them rest on a cutting board for at least 5 minutes. This lets the juices redistribute and keeps the meat tender.
While the meat rests, return the roasted potatoes to the oven for another 5-10 minutes, allowing them to crisp up even further.
Slice the steaks against the grain and serve alongside the crispy potatoes. Drizzle some of the garlic butter mixture over the top for added flavor.
Notes
Let the steaks rest before slicing to keep them tender.
