Roast Beef Tenderloin Rub
- Sea salt
- Black pepper
- Dried thyme leaves
- Granulated garlic
- Olive oil
This simple mix of seasonings complements a hearty beef tenderloin perfectly and gives it a beautiful crust. Serve it with Herb Garlic Butter for extra flavor.
We use a rosemary sea salt mixture for our Sous Vide Beef Tenderloin with Garlic Herb Butter! You can also try it with this oven-roasted recipe.
You will also want to make sure your tenderloin is trimmed before cooking it.
How Prepare Beef Tenderloin
Trim
The whole beef tenderloin has a fibrous connective tissue called a silver skin that should be trimmed. It's shiny and easy to spot and cut away. You will also want to trim any excess fat.
If you do not want to trim beef tenderloin yourself, ask your butcher to do it for you! And while you're at it, have them french, or tie, the roast. This will help it cook more evenly.
- With your tenderloin laying flat, carefully cut just under the silver skin with your knife. Keep the blade close to the meat, without removing too much of the meat itself. Cutaway from yourself.
- Pull the tissue tightly against the blade using your free hand for a clean cut. Cut through the tissue until you trim it off completely. Do the same for any large white sections on the beef, which is excess fat.
Tie
This is optional - To tie your own roast, follow these instructions. It's easy to do:
- Loop kitchen string around one end of the tenderloin and tie it into a tight knot.
- Loop the string around your hand, and then pull that loop over the tenderloin.
- Continue making loops 1-inch apart from each other, making sure each loop is snug against the beef.
- Tie the end with a knot to finish tying the roast.
How to Roast a Beef Tenderloin Roast
- At least 4 hours before cooking your roast, season it with sea salt, black pepper, granulated garlic, and dried thyme, then store in plastic wrap or a plastic bag in the refrigerator. Pat down the spices so they stick well.
- Preheat your oven to 450°F. While the oven preheats, take your seasoned roast out of the refrigerator and place it on a rack in a small roasting pan, or on a small baking sheet with sides. Drizzle olive oil evenly over the roast. Allow it to come to room temperature.
- Place your roast in the oven and sear for 15 minutes to sear it. When 15 minutes is up, reduce the oven temperature to 325°F.
- Continue to cook for 1 hour at 325°F, or more or less time depending on the size of your roast (see chart below).
- Remove from the oven and tent with foil for 15 minutes before carving. Serve, and enjoy!
FAQs
What is a roast beef tenderloin?
It is a long, narrow, and lean muscle within the Loin. This is the most tender cut of beef available. It is also known as a tenderloin steak or filet mignon when cut. It is typically a more expensive cut that is a perfect splurge for the holidays. This cut of beef will melt in your mouth, it is amazingly delicious.
How do you get the perfect crust on a beef tenderloin?
You can achieve a perfect crust for your whole beef tenderloin recipe by following two rules: use sea salt instead of regular salt, season the roast ahead of time, and sear it for 15 minutes at 450°F before lowering the temperature of your oven. These two simple steps will ensure a perfect crust every time!
Should I sear a beef tenderloin before roasting?
I highly recommend always searing your roast in the oven by starting out with a temperature of 450°F for 15 minutes before lowering it to 325°F. No matter the size of your roast is, you should sear it for 15 minutes at this temperature before roasting it.
Should beef tenderloin be cooked on a rack?
Cooking on a roasting rack allows the hot air of your oven to circulate over the whole tenderloin, so it will cook more evenly throughout.
How long should beef tenderloin sit out before cooking?
I always let my tenderloin come to room temperature before roasting, approximately one hour. It will cook more evenly this way.
How much beef tenderloin do I need per person?
About ½ a pound of roast per person is usually a perfect serving. For a 6 lb. roast like we use in this recipe, you will be able to feed approximately 12-14 people. I always like to add a little more because I love leftovers!
Can you freeze beef tenderloin?
This will keep in the freezer for up to two months.
Beef tenderloin vs. Filet Mignon
Is beef tenderloin and filet mignon the same thing? Well, not quite! Filet mignon and beef tenderloin both come from the same cut of beef, but tenderloin is the whole cut. Filet mignon is actually steaks cut from the whole tenderloin.
Roast Beef Tenderloin Temperature
- 3 lb. roast: 30 minutes
- 4 lb. roast: 40 minutes
- 5 lb. roast: 50 minutes
- 6 lb. roast: 1 hour
These cooking times will give you a medium-rare roast. For a more well-done temperature, roast for an additional 10 minutes or so.
For best results, always use a meat thermometer to check for desired doneness.
We make it easy to follow with our easy-to-follow Roast Beef Temperature Chart.
Recipes Tips
- Trim your roast: Remove the silver skin and excess fat before roasting. This will give you a more tender, flavorful roast.
- Tie your roast: Tie the roast with kitchen string so it cooks more evenly in the oven. Tenderloin has a skinny end that should be tucked underneath the roast.
- Use a rack: Use a roasting rack and a shallow baking pan, or a roasting pan, to roast tenderloin. Using a rack allows hot air to circulate evenly around the beef.
- Sear at 450°F first: Searing your roast before lowering the oven temperature will give you the most beautiful crust.
How to Reheat Beef Tenderloin
If frozen, thaw your whole beef tenderloin recipe first!
- Wrap tenderloin in foil with leftover cooking juices, sauce like au jus, or beef broth, so it retains moisture.
- Carefully reheat at a low temperature (225˚F) until the beef reads 150˚F on a meat thermometer. Serve, and enjoy!
