Seasonal Vegetables
Method
Steak
Bring steaks to room temperature
Remove steaks from the refrigerator 30–45 minutes before cooking so they come to room temperature. Pat dry thoroughly with paper towels.
Heat a heavy skillet (preferably cast iron) over high heat until smoking hot, about 4–5 minutes. Add 2 tbs neutral oil and swirl to coat.
Add steaks to the pan, spacing them so they do not touch. Sear without moving 2.5–3 minutes until a deep brown crust forms. Flip and add 2 tbs unsalted butter, smashed garlic cloves, and thyme sprigs to the pan.
Transfer steaks to a cutting board and tent loosely with foil. Rest for 6–8 minutes to allow juices to redistribute before slicing and saucing.
Lobster Butter Sauce (to top steak)
While steaks rest, make the lobster butter sauce. In a small saucepan over medium heat, add the minced shallot and 1 tbs butter; cook until softened and translucent, about 2 minutes.
Deglaze the pan with 2 tbs dry white wine, scraping up any browned bits. Reduce by half, about 1–2 minutes.
Lower the heat to low. Whisk in the cold butter, one cube at a time, to emulsify into a smooth, silky sauce. Do not let the sauce boil; keep it just warm.
Stir in the chopped cooked lobster meat, 1 tsp lemon juice, chopped chives, 1 tsp salt, and 1/2 tsp black pepper. Heat just until lobster is warmed through, about 30–45 seconds. Taste and adjust seasoning.
Spoon 2 tbs of lobster butter sauce over each rested steak just before serving.
Fully Loaded Crispy Mashed Potatoes
Mash the potatoes with 3 tbs butter, 1/2 cup warm milk, and 2 tbs sour cream until mostly smooth but slightly rustic. Stir in 1/2 cup shredded cheddar, crumbled bacon, green onions, 1/2 tsp salt, and 1/4 tsp black pepper. Adjust seasoning to taste.
Transfer crispy mashed potatoes to the plate and keep warm until serving.
Seasonal Vegetables
Trim and prepare vegetables (snap off woody ends of asparagus, peel baby carrots if needed, trim broccolini). Pat dry.
Toss vegetables with 1 tbs olive oil, 1/2 tsp salt, and 1/4 tsp black pepper.
For quick roasting: preheat oven to 425°F (220°C). Spread vegetables on a single layer on a baking sheet and roast 8–12 minutes until tender-crisp and edges are lightly browned. For sautéing: heat a skillet over medium-high heat and cook vegetables in a single layer, stirring occasionally, 6–8 minutes until tender-crisp.
Finish vegetables with a squeeze of lemon juice from the lemon wedges just before plating.
Plating and Serving
Spoon the warmed lobster butter sauce over the steak slices (about 2 tbs per steak) and sprinkle any remaining chives on top.
Garnish plates with lemon wedges and serve immediately.
