Method
- Preheat oven to 425°F. Combine breadcrumbs, garlic, onion, melted butter, and parsley in a bowl to create the stuffing mixture.
- Place tenderloin on cutting board. Begin spiral butterflying by making horizontal cuts every inch, leaving 1/2 inch connected on one side.
- Continue spiral cutting until meat opens into one flat piece. Gently pound thicker areas to create uniform 3/4-inch thickness.
- Spread breadcrumb mixture evenly over flattened meat, leaving a 1-inch border around edges.
- Roll tenderloin tightly from one long side, then secure with kitchen twine at 1-inch intervals.
- Season outside with salt and pepper. Place seam-side down on wire rack in roasting pan.
- Roast for 50-70 minutes, using meat thermometer to check for 140°F (medium-rare) or 155°F (medium).
- Remove when roast reaches 5-7°F below target temperature, as it continues cooking while resting.
- Let rest for 15 minutes before slicing to allow juices to redistribute.
Notes
Can be stuffed and tied up to 6 hours ahead—cover and refrigerate, then bring to room temperature 1 hour before cooking. Use reliable meat thermometer to prevent overcooking. Serve with roasted vegetables and potatoes for complete holiday meal.
