What You will Need for Beef Tenderloin Roast:
We like the Costco beef tenderloin for the price and quality. They sell both a choice and prime tenderloin. We go with the more expensive prime for holidays and special occasions, but either will work. Get the best you can afford.
2 to 2 1/2 lb beef tenderloin roast (get the even center-cut if possible) Roasting Pan – use any oven-safe skillet or roasting pan. We used a cast iron pan. Kitchen String – to tie your roast into a cylinder for even cooking. Thermometer – an oven-safe thermometer will ensure a perfectly cooked roast. This is one of the best investments you’ll make for all your future roasts. Here is the Carving Set we use and love.
Cost Saving Tip: An un-trimmed tenderloin can be significantly less expensive. If your tenderloin is not already trimmed, use a thin knife to cut away and remove the excess fat, connective tissue, and silver skin. Here is a great tutorial on how to trim beef tenderloin.
How to Tie Beef Tenderloin (2 ways)
Tying a tenderloin is important for even cooking. Do not skip this step. It helps to get an even-thickness roast, but if you have a thin flap on one end, tuck it under the roast and tie it with kitchen string to create an even shape. What can I substitute for kitchen string? Kitchen twine is made from natural fibers so it won’t melt or catch fire at high temperatures. If you don’t have kitchen string, you can use unwaxed, unflavored dental floss.
Our #1 Tip to Cooking Beef Tenderloin:
For even cooking, we highly recommend bringing the tenderloin to room temperature before roasting. We like to take it out of the refrigerator and let it sit at room temperature for 1 to 2 hours.
Common Questions:
How Long to Cook Beef Tenderloin?
Roast your tenderloin to your desired doneness. The most important tool for getting the timing right is an oven-safe thermometer. Here are the final doneness temperatures. Remove the roast from the oven 5 to 10 degrees before it reaches its final temperature since the temperature will continue to rise as it rests. For example, we take it out at 130˚F for medium doneness and it reaches a final doneness temperature of 135-140˚F.
22-23 minutes for rare (120-125˚F) – red, shiny center 24-26 min medium-rare (130-135˚F) – red to deep pink center 28-30 min for medium doneness (135-140˚F) – light pink center 30-32 min for medium-well (140-145˚F) – little pink (USDA recommends 145˚F) 33-35 min for well done (150˚F) – no pink (don’t do this to your meat)
