- Bring the roast to room temperature (leave out 1–2 hours before roasting).
- Pat dry with paper towels.
- Mix salt, cracked pepper, garlic powder, and onion powder.
Step 2: Season Generously
- Rub the entire roast with olive oil.
- Press the spice mixture all over, including the sides and bottom.
- For added depth, tuck a few sprigs of rosemary under the twine.
Step 3: Roast Low and Slow
- Preheat oven to 450°F (232°C).
- Place roast bone-side down on a rack in a roasting pan.
- Roast at 450°F for 20 minutes to form a crust.
- Lower temperature to 325°F (163°C) and roast for 90–110 minutes, until internal temp is:
- 120°F for rare
- 130°F for medium rare
Step 4: Rest and Serve
- Remove roast and tent with foil.
- Let rest for 20–30 minutes before slicing (very important!).
- Carve between the bones and serve with au jus or horseradish sauce.
Tips for Success
- Letting the meat come to room temperature ensures even cooking.
- Always use a meat thermometer for perfect doneness.
- Resting the roast keeps it juicy.
Variations
- Add a Dijon mustard rub before the pepper crust.
- Mix in smoked paprika or cayenne for a spicier edge.
