Step-by-Step Instructions
- Melt 4 tablespoons of salted butter in a large skillet over medium heat. Add diced onion and cook for about 5 minutes until translucent and fragrant.
- Stir in minced garlic and sauté for 30 seconds, then incorporate baby spinach in batches, wilting down for roughly 12 minutes until tender.
- Prepare the peppercorn crust: In a resealable plastic bag, combine tricolor peppercorns and sugar, crush them until coarsely ground.
- Season sirloin steak generously with kosher salt, then press the crushed peppercorn mixture onto both sides.
- Heat a cast-iron skillet over high heat for about 5 minutes, add 1 tablespoon of olive oil, then place the steak in the pan.
- Sear the steak for approximately 6 minutes on each side until a deep brown crust forms.
- After searing, reduce heat to medium and add the remaining 3 tablespoons of butter, rosemary sprigs, and crushed garlic.
- Baste the steak with the melted butter for about 5 minutes, checking for an internal temperature of 115-120°F for medium-rare.
- Transfer steak to a cutting board to rest for 10 minutes, then slice against the grain and serve alongside warm creamed spinach.

Notes
Ensure skillet is hot before adding steak for optimal sear. Rest steak post-cooking for juicy results. Cook spinach well to avoid watery texture. Use freshly cracked peppercorns for depth of flavor.
