Garlic-Rosemary Roast Beef with Horseradish Sauce
Preheat oven to 400 degrees F.Advertisement
Season roast with 3/4 teaspoon salt and 1/2 teaspoon pepper. Heat oil in a large ovenproof skillet (see Tip) over medium-high heat. Add the roast and cook, turning every few minutes, until browned on all sides, about 10 minutes. Remove from heat.
Combine butter, shallot, rosemary, and minced garlic; spread on top of the roast. Transfer the pan to the oven. Roast until a thermometer inserted in the center of the meat registers 125-130 degrees F for medium-rare, 35 to 40 minutes. Transfer the roast to a cutting board and let rest for 10 minutes.
Meanwhile, whisk grated garlic, yogurt, horseradish, mustard, and lemon juice in a small bowl. Season with the remaining 1/4 teaspoon each salt and pepper. Slice the beef thinly and serve with the sauce.
Tip: If you don't have a large ovenproof skillet, you can brown the roast in a large skillet and transfer it to a roasting pan for Step 3.
To make ahead: Season roast with salt and pepper; refrigerate for up to 1 day. Prepare butter mixture (Step 3) and sauce (Step 4) and refrigerate for up to 1 day.
