What Temp To Cook Beef Tenderloin

ByLily

Beef tenderloin is an expensive cut, so cooking it at the right temperature protects both your investment and your dinner plans. If you are wondering what temp to cook beef tenderloin, the short answer is 425°F in the oven for the initial sear, then lower the heat to 325°F to finish. But the full answer depends on how you like your meat and how you plan to serve it.

This guide breaks down oven temps, internal doneness temps, and simple steps so you get a juicy, tender roast every time.

What Temp To Cook Beef Tenderloin

There are two temperatures that matter when you cook beef tenderloin: the oven temperature and the internal temperature of the meat.

  • Oven temp for searing: 425°F to 450°F for the first 15 minutes
  • Oven temp for roasting: 325°F after the sear
  • Internal temp for rare: 120°F to 125°F
  • Internal temp for medium rare: 130°F to 135°F
  • Internal temp for medium: 140°F to 145°F

Most cooks aim for medium rare. It gives you the best texture and flavor without drying out the meat. Pull the roast out when it hits 5 to 10 degrees below your target, because it keeps cooking as it rests.

Why The Oven Temp Changes Mid Cook

The high heat at the start creates a browned crust on the outside. That crust adds flavor and looks great on the plate. Once the crust forms, you drop the heat so the inside cooks evenly without overcooking the edges.

If you skip the high heat step, you get a gray roast with no crust. If you keep the heat high the whole time, the outside burns before the center is done.

Internal Temperature Chart For Beef Tenderloin

Use a meat thermometer for the best results. Here is a quick guide:

  • Rare: pull at 120°F, rest to 125°F
  • Medium rare: pull at 125°F, rest to 130°F to 135°F
  • Medium: pull at 135°F, rest to 140°F to 145°F
  • Medium well: pull at 145°F, rest to 150°F
  • Well done: pull at 155°F, rest to 160°F

Well done tenderloin tends to be dry and firm. This cut has very little fat, so it needs a gentle hand.

How To Cook Beef Tenderloin Step By Step

Follow these steps for a roast that comes out right every time.

  1. Take the roast out of the fridge 30 to 45 minutes before cooking. Room temp meat cooks more evenly.
  2. Pat the surface dry with paper towels. Dry meat browns better.
  3. Season all sides with salt and pepper. You can add garlic powder or herbs if you like.
  4. Preheat your oven to 425°F.
  5. Heat a skillet or roasting pan on the stove over high heat. Add a little oil.
  6. Sear the roast on all sides for 2 to 3 minutes per side.
  7. Move the pan to the oven and roast at 425°F for 15 minutes.
  8. Lower the oven to 325°F and keep roasting until the internal temp reaches your target.
  9. Remove the roast and tent it with foil. Let it rest 15 to 20 minutes.
  10. Slice against the grain into thick rounds and serve.

The rest time is not optional. It lets the juices settle back into the meat. If you cut too soon, the juice runs out and the meat turns dry.

How Long Does It Take To Roast Beef Tenderloin

Time depends on the size of your roast and your oven. A whole tenderloin runs 4 to 6 pounds. A center cut roast runs 2 to 3 pounds.

  • 2 to 3 pound roast: 25 to 35 minutes at 325°F after searing
  • 4 to 5 pound roast: 35 to 45 minutes at 325°F after searing
  • 5 to 6 pound roast: 45 to 55 minutes at 325°F after searing

These times are rough guides only. Always trust your thermometer over the clock. Ovens run hot or cold, and the shape of the roast changes the cook time.

Should You Sear Before Or After Roasting

Searing before roasting is the classic method. It builds a crust and starts the cooking process. Some cooks sear after roasting using a hot pan. That works too, but it can be messy and it raises the internal temp fast.

For beginners, sear first. It is easier to control and gives you a head start on browning.

Tips For A Juicy Beef Tenderloin

  • Use a digital meat thermometer. Guessing leads to overcooked meat.
  • Do not trim off all the fat. A thin layer adds flavor and moisture.
  • Let the meat rest before slicing. This is the most common mistake.
  • Slice thick rounds, about 1 inch, so the meat stays warm and tender.
  • If you tie the roast with kitchen twine, remove it before slicing.

Common Mistakes To Avoid

Cooking cold meat straight from the fridge is a big one. The outside overcooks while the inside stays raw. Another mistake is skipping the rest. And a third is relying on time instead of temperature.

Also avoid opening the oven door too often. Each time you do, the heat drops and the cook time stretches.

Frequently Asked Questions

What Is The Best Temp For Beef Tenderloin In The Oven

Start at 425°F for 15 minutes, then drop to 325°F for the rest of the cook. This gives you a good crust and an even interior.

What Internal Temp Should Beef Tenderloin Be

For medium rare, pull it at 125°F and let it rest to 130°F to 135°F. For rare, pull at 120°F. For medium, pull at 135°F.

Can I Cook Beef Tenderloin At 350°F

Yes. A steady 350°F works fine, but you may not get as strong a crust. It will take a bit longer than the sear then low method.

How Do I Know When Beef Tenderloin Is Done

Use a meat thermometer inserted into the thickest part. Do not touch bone or fat. Read the temp and compare it to your target.

With the right oven temp and a good thermometer, beef tenderloin comes out tender and juicy. Stick to 425°F for the sear, 325°F for the roast, and pull it at 125°F for medium rare. Rest it, slice it, and enjoy a roast that does justice to the price you paid.
