Start by making the garlic butter. In a small bowl, mix 4 tablespoons of softened butter with chopped garlic and parsley. Once combined, cover and refrigerate the mixture until you’re ready to use it. This step infuses the butter with rich garlic flavor and adds freshness from the herbs.
Pat the ribeye steak dry using a paper towel. Brush both sides with ½ tablespoon of olive oil and season generously with sea salt. Heat your grill or cast iron pan over high heat and sear the steak for 3–5 minutes per side. Use a thermometer to check your preferred doneness. Once done, place it on a warm plate, spread 1 tablespoon of butter on top, and tent with foil to rest for 5 minutes.
Wipe the pan clean and set it to medium-low heat. Add 2 tablespoons of butter and 1 tablespoon of olive oil. Toss in the trimmed asparagus along with 4 tablespoons of water. Let them cook for about 5 minutes, turning them occasionally. Watch the garlic to prevent it from burning. Season with sea salt and transfer the asparagus to a serving plate.
Season your shrimp with salt on both sides. Wipe down the pan again and return it to medium heat. Add the remaining 2 tablespoons of butter and 1 tablespoon of olive oil. Place the shrimp in the pan and cook for 2–3 minutes per side, depending on their size. They should be pink on the outside and opaque on the inside when done.
Slice the ribeye steak thinly against the grain for the best texture. Arrange the steak slices, cooked shrimp, and asparagus on a serving platter. Drizzle the entire dish with leftover pan juices and the chilled garlic butter you prepared earlier. Serve hot and enjoy the explosion of flavor in every bite.
