Your beef needs to warm up before cooking for even results. Take it out of your fridge about 1-2 hours ahead of time. Unwrap it, dust all sides with salt, then wrap it back up.

Warm your oven to 375°F (190°C). Adjust one rack to the middle position and put another one just below it.

Wipe the meat dry using paper towels. Make 8 to 10 tiny cuts around the beef with a sharp knife tip. Push a small piece of garlic into each opening.

Coat the entire piece of meat with olive oil. Sprinkle salt and pepper all over it.

Set the meat right on the middle rack with the fatty part facing up. Place a pan underneath on the lower rack to catch any drippings.

First cook at 375°F (190°C) for 30 minutes to get a nice brown crust. Then turn down to 225°F (107°C). The rest of the cooking will take about 1 1/2 to 2 1/2 hours.

When you see juices dripping and the outside looks brown, check how hot it is inside with a meat thermometer. Take it out when it reaches 135°F to 140°F for a pink middle.

Put the meat on a board and cover loosely with foil to keep warm. Let it sit for 20-30 minutes. For the sauce, take the drip pan and put it on medium heat. Pour in some water, red wine, or beef broth to loosen the tasty bits. Mix cornstarch with a little water, pour into the pan, and stir quickly as it thickens to avoid clumps.

After resting, cut the meat into thin slices. Pour the sauce over the top or serve it separately.
