Preheat your oven to 425°F and line a baking sheet with parchment paper.
Wash and dice the russet potato into small cubes. Toss the potato cubes with a pinch of salt and pepper.
Spread the potatoes evenly on the baking sheet and roast in the oven for about 20-25 minutes until crispy and golden, stirring halfway through.
Meanwhile, trim the ends of the green beans and rinse them. Steam or blanch the green beans for 3-4 minutes until tender but still crisp, then set aside.
Pat the ribeye steak dry with paper towels and season both sides with salt and pepper.
Heat a skillet over medium-high heat. Once hot, add the steak and sear for about 3-4 minutes per side (depending on thickness) until a crust forms and the steak reaches your desired doneness.
In the last minute of cooking, add the butter and crushed garlic (or minced garlic) into the skillet. Spoon the melted garlic butter over the steak continuously to enhance flavor.
Remove the steak from the skillet and let it rest for a few minutes.
Plate the steak alongside the roasted crispy potatoes and tender green beans. Drizzle any remaining garlic butter from the skillet over the steak for extra flavor.
Serve immediately and enjoy your balanced, flavorful meal.
