Beef Tenderloin

Garlic Mashed Potatoes

Method

Beef Tenderloin

  1. 1

    Prepare the Beef

    Preheat your oven to 400°F (200°C). Season the beef tenderloin with salt, black pepper, and chopped fresh rosemary. Rub the olive oil all over the tenderloin to ensure even cooking.

  2. 2

    Sear the Beef

    In a large skillet, heat a tablespoon of olive oil over medium-high heat. Once hot, add the seasoned beef tenderloin and sear on all sides until browned, about 2-3 minutes per side.

  3. 3

    Roast the Beef

    Transfer the seared beef tenderloin to a baking dish. Add whole garlic cloves around the beef, then roast in the preheated oven for 20-25 minutes for medium-rare, or until desired doneness is reached. Use a meat thermometer to check the internal temperature (135°F for medium-rare).

  4. 4

    Rest the Beef

    Once cooked, remove the beef from the oven and let it rest for 10 minutes before slicing.

Garlic Mashed Potatoes

  1. 5

    Prepare the Potatoes

    Peel the russet potatoes and cut them into even-sized chunks. Place them in a large pot and cover with cold water. Add a teaspoon of salt to the water.

  2. 6

    Cook the Potatoes

    Bring the pot of potatoes to a boil over high heat. Reduce the heat to medium and simmer until the potatoes are tender, about 15-20 minutes.

  3. 7

    Add Garlic

    In the last 5 minutes of cooking, add the garlic cloves to the pot with the potatoes.

  4. 8

    Mash the Potatoes

    Drain the potatoes and garlic, then return them to the pot. Add butter, milk, salt, and black pepper. Mash until smooth and creamy.
