Instructions
- Season the steak: Pat the top sirloin dry. Season generously on both sides with salt and pepper. Let it sit at room temperature for 20–30 minutes while you prep the vegetables.
- Start the steak in the oven (reverse sear): Preheat oven to 275°F. Place the steak on a wire rack set over a baking sheet. Insert an instant‑read thermometer into the thickest part if you have one. Roast 20–30 minutes, until internal temp reaches about 115–120°F for medium‑rare (or 125°F for medium). Time will vary by steak thickness.
- Prep vegetables: While steak is in the oven, slice the onion, wash and slice kale, and mince the garlic. Keep 1 minced clove separate for the butter sauce.
- Cook mushrooms and greens (stove): Heat 1 Tbsp olive oil in a large skillet over medium‑high. Add sliced onion and cook 2–3 minutes until starting to soften. Add shiitake mushrooms and a pinch of salt; cook 4–5 minutes, stirring, until browned and most moisture is gone.
- Finish the greens: Add 2 minced garlic cloves and a pinch of red pepper flakes; cook 30 seconds. Add kale and 2–3 Tbsp water, plus a pinch of salt. Toss, cover, and cook 3–4 minutes, then uncover and sauté another 2–3 minutes until tender but still bright. Squeeze over a little lemon juice, adjust seasoning, and keep warm on low.
- Sear the steak on the stove: When the steak reaches target temp in the oven, remove and pat dry again if needed. Heat a heavy skillet (cast‑iron is ideal) over high. Add 1–2 Tbsp oil. When just smoking, sear steak 1–2 minutes per side until a deep brown crust forms, searing edges briefly as well. Reduce heat to medium‑low.
- Make quick pan butter sauce: Turn heat to low. Add 2 Tbsp butter and the remaining minced garlic to the skillet with the steak. Tilt the pan and spoon the foaming butter over the steak for 30–60 seconds. Optionally squeeze in a teaspoon or two of lemon juice. Transfer steak to a cutting board to rest 5–10 minutes. Keep the buttery juices in the pan.
- Slice and serve: Slice steak across the grain into thick strips. Divide the mushroom‑kale mixture between two plates. Top with steak slices and spoon the garlic‑lemon butter from the pan over the meat. Serve immediately.
