How to cook a whole or large piece of beef tenderloin. Note from UnknownChef86: This is a recipe I adopted in 2006.

Ingredients Nutrition


  1. Preheat the oven to 500 degrees F.
  2. Place the beef on a sheet pan and pat the outside dry with a paper towel.
  3. Spread the butter on with your hands.
  4. Sprinkle evenly with the salt and pepper.
  5. Roast in the oven for exactly 22 minutes for rare and 25 minutes for medium-rare.
  6. Remove the beef from the oven, cover it tightly with aluminum foil, and allow it to rest at room temperature for 20 minutes.
  7. Remove the strings and slice the fillet thickly.
  8. Note: Be sure your oven is very clean or the high temperature will cause it to smoke.

Cool - this worked perfectly! We usually cook tenderloins on the grill outside, but a rainy cold night forced me to try this. Not sure I'll ever fire up the grill again for a whole tenderloin! This takes the guesswork out of doneness - it just comes out perfectly cooked and tender and tasty - what more is there to say?

This is definitely a Barefoot Contessa recipe!!! I used this recipe as the star dish for my Valentine's menu and it was terrific. I bought 2.5 pd filet of beef, lathered it with butter and used plenty of salt and pepper to cover all surfaces. I cooked it exactly to 22 minutes and covered as directed. The filet was expensive, but well worth it. Quick, easy and great tasting. I served it with Mean Chef's Mushroom Gravy, Barefoot Contessa's Garlic Roasted Potatoes and Sharlene W's Spinach, Apple and Pecan Salad. The whole menu, including the beef was awesome!!!!
