Garlic Roasted Tenderloin with Lemon Parmesan Gremolata
A classic steakhouse-style beef tenderloin crusted with garlic and cracked pepper, finished with a bright gremolata sauce of fresh parsley, lemon, and Parmesan. The meat roasts until medium-rare with a golden crust, then rests to retain juices before carving. The vibrant herb sauce cuts through the richness of the beef, making this elegant enough for dinner parties yet straightforward enough for weeknight entertaining. This version emphasizes the contrast between the savory roasted meat and the acidic, herbaceous condiment.

Tips
Use an ovenproof meat thermometer for accuracy; the carryover cooking during rest raises the internal temp 10-15°F, so remove at 135°F for true medium-rare.
Don't skip the 15-20 minute rest; it allows muscle fibers to relax and retain juices, resulting in moist slices.
Make gremolata while the roast rests so it's fresh and vibrant when served.
Good to Know
Slice leftover tenderloin, cover, and refrigerate up to 3 days. Store gremolata separately up to 2 days in an airtight container; refresh with fresh lemon juice before serving.
Prepare gremolata up to 2 hours ahead; keep in airtight container. Season and crust the roast up to 12 hours before roasting; store covered in refrigerator.
Serve at room temperature or warm, with gremolata on the side or spooned over sliced meat. Pair with roasted potatoes, asparagus, or a light salad.
Common Mistakes
Skip the rest to avoid dry, tough meat; carryover cooking completes the process.
Don't roast covered; air circulation creates the brown crust.
Blend gremolata just before serving to avoid discoloration of parsley.

FAQ
Can I cook this on the stovetop instead of roasting?
Yes. Sear the crusted roast in a hot oven-safe skillet 2-3 minutes per side, then finish in a 350°F oven using the same thermometer method. This creates a deeper crust but adds 5-10 minutes to total time.
What if I don't have a meat thermometer?
Use the touch test: medium-rare feels soft with slight resistance at the center when pressed. However, a thermometer is far more reliable for expensive cuts like tenderloin.
How long can I keep leftover sliced tenderloin?
Up to 3 days refrigerated in an airtight container. Reheat gently in a 275°F oven with a few tablespoons of beef stock to restore moisture.
