Swaps and Notes

• Steak: Ribeye and sirloin are fantastic choices for this recipe due to their flavor and tenderness. You can also use other cuts like a New York strip or a filet mignon. The key is to choose a steak that is about 1 inch thick for a good sear and even cooking.
• Lemon Herb Butter: The combination of parsley, chives, and lemon zest is a perfect blend of fresh and zesty flavors. The user’s notes mention other herbs like tarragon or rosemary, which would also be delicious. Tarragon would add a subtle anise flavor, while rosemary would give it a rustic, earthy note.
• Mashed Potatoes: Yukon Gold potatoes are a great choice for mashed potatoes, as they are creamy and have a wonderful buttery flavor. You can also use russet potatoes for a fluffier texture.
• Herb Variations: Feel free to experiment with other herbs in the butter for different flavors. A little bit of fresh thyme, rosemary, or even some fresh oregano would all be fantastic additions.
• Steak Doneness: The user’s notes mention using a meat thermometer to ensure your steak is cooked to your preferred level of doneness. This is a crucial tip for a perfect result.

List of Steps for the Recipe

1. Prepare the Lemon Herb Butter: In a small bowl, mix together the softened butter, finely chopped parsley, chives, lemon zest, and minced garlic. Season with salt and pepper to taste. Place the butter mixture on a piece of plastic wrap and roll it into a log. Refrigerate it for at least 30 minutes, or until it is firm.
2. Cook the Steaks: Season the steaks generously on both sides with salt and pepper. Heat a grill or skillet over high heat and add a splash of olive oil. Once the oil is shimmering, add the steaks to the pan. Cook for 4−5 minutes on each side for a medium-rare steak. Adjust the time for your desired doneness.
3. Rest the Steaks: Once the steaks are cooked, transfer them to a plate. Loosely tent them with aluminum foil and let them rest for a few minutes. This is a crucial step that allows the juices to redistribute, ensuring a tender and juicy steak.
4. Make the Mashed Potatoes: While the steaks are resting, start on the mashed potatoes. Peel and cube the potatoes and place them in a pot of salted water. Bring to a boil and cook until they are tender, which should take about 15−20 minutes.
5. Mash the Potatoes: Drain the potatoes and return them to the pot. Add the heavy cream and butter, and mash with a potato masher until they are smooth and fluffy. Season with salt and pepper to taste.
6. Serve: Slice the chilled lemon herb butter and place a pat or two on top of the hot, rested steaks. Serve the steaks immediately with a side of the fluffy mashed potatoes.

Tips for Success

• Pat the Steak Dry: Moisture is the enemy of a good sear. Patting the steak dry before seasoning ensures you get a beautiful, browned crust.
• Use a Hot Pan: Make sure your skillet or grill is hot before you add the steaks. This creates an immediate sear and prevents the steak from sticking.
• Let the Steak Rest: Don’t skip this step! Resting the steak is essential for a juicy, tender result. The hot juices are forced to the center of the steak while cooking, and resting allows them to flow back into the meat.
• Use a Thermometer: For a perfect result, use a meat thermometer. The internal temperature for medium-rare is about 135°F (57°C).

Serving Suggestions and Pairings

This classic meal is a complete plate on its own. The richness of the steak and mashed potatoes is perfectly balanced by the fresh lemon herb butter. A side of roasted asparagus or a simple green salad would be a lovely addition.

For a drink pairing, a full-bodied red wine like a Cabernet Sauvignon or a Merlot would be a perfect complement to the rich, savory flavors of the steak.

Storage and Leftover Tips

This dish is best served immediately. Reheating the steak will likely cause it to overcook and lose its tenderness. However, you can store any leftover mashed potatoes and lemon herb butter in airtight containers in the refrigerator for up to 3 days.
