Instructions

Set your oven to 400°F. This high heat ensures you'll get a proper sear on the stovetop before the roast goes in.
Open the butterflied lamb loin flat on your work surface, cut side facing up. Season the interior generously with salt and your Creole spice blend — this is where the flavor really penetrates. Lay one rosemary sprig down the center, then roll the meat back up. Use the second rosemary sprig as natural twine, wrapping it around the roast to hold everything together. The herbs will infuse the meat while keeping it compact.
Rub the exterior of the tied roast with more salt, the coriander, and cumin. Press the spices into the meat so they adhere — you want every bite to have that earthy, warm coating.
Pour the olive oil into a large oven-safe skillet and heat over high heat until it shimmers but doesn't smoke. The oil should move quickly when you tilt the pan — that's your signal it's ready for searing.
Add the lamb roast and sear on all sides, turning every minute or so until each surface is deep golden brown. This takes about 5 minutes total. You're building flavor with this step, so don't rush — good browning equals better taste.
⏱ 5 min
Slide the skillet directly into the preheated oven. Roast for exactly 20 minutes for medium-rare lamb — the internal temperature should hit 130°F. Don't open the oven door during cooking, as this releases valuable heat.
⏱ 20 min
Pull the roast from the oven and let it rest on a cutting board for 10 minutes. This resting period allows the juices to redistribute throughout the meat, giving you more tender, juicy slices.
⏱ 10 min
Remove the rosemary twine and slice the roast into thick 1-inch medallions. Cut against the grain for the most tender bite, and arrange on a warm platter to serve immediately.
