Beef Tenderloin with Red Wine Sauce

Step 1

In a medium saucepan, melt 4 tbsp of the butter over medium heat. Add the shallots and cook, stirring occasionally, until soft, about 4 minutes.

Step 2

Add the wine, 2 cups of broth, thyme, salt, and pepper, and bring to a boil. Lower the heat to medium and simmer for 20 minutes, or until reduced by half. Turn off heat. This can be done up to 3 days in advance. See NOTES.

Step 3

Meanwhile, rub 2 tbsp of the oil all over the roast. Use your fingers to rub in the rosemary and garlic all over the roast. Liberally salt and pepper the entire roast. Allow the roast to sit at room temperature for 1 hour.

Step 4

Preheat oven to 425°F.

Step 5

Heat 2 tbsp oil and 2 tbsp butter in a large oven-proof skillet or Dutch oven over medium-high heat. Add the roast and sear until browned all over, about 7 minutes. It's okay if you have to bend the roast to fit in the skillet.

Step 6

Place the skillet in the oven and cook until an internal temperature of 125°F is reached (for medium-rare). If you don't have an oven-proof skillet, transfer the roast to a baking pan. An instant-read thermometer ensures the correct internal temperature. See NOTES regarding cooking temperatures.

Step 7

Remove the roast from the skillet/pan, and allow to rest while you finish the sauce.

Step 8

Place the skillet (or pan) on the stove over medium heat. Add the remaining ¼ cup of beef broth and use a spatula to scrape up the bits stuck to the pan. Bring to a simmer and sprinkle with another ¼ tsp of salt. Pour the broth into the pan with reserved sauce. Stir to combine. Strain into a gravy boat if serving immediately. If not serving immediately, store the sauce and then gently reheat over low heat on the stove in a pan.

Step 9

Cut the twine from the meat and then slice the roast into ½-inch medallions. Place on a serving platter and serve warm, or at room temperature, with sauce on the side. Sprinkle the slices with finishing salt, if desired.
