How to Make The Perfect Filet Mignon Roast…

1.  First, we gave this roast its full flavor by adding prosciutto, onions, and seasonings to the roast.

2.  Second, the secret to making a perfect roast is keeping water on the bottom of the pan while roasting in the oven.

3.  Third, when roasting, we highly recommend using a roasting rack with this recipe.  This will help and ensure keeping the roast super moist while cooking.

4.  Finally and in addition, the key to making this filet mignon roast perfect,  is by rotating the roast every half hour, while it’s in the oven.

Our family LOVES this Filet Mignon Roast on special occasions, and it’s a nice alternative.

Before you begin…  Important Notes and Tips about the Filet Mignon Roast:

  • When shopping for this kind of meat, you will sometimes find it labeled as Chateaubriand,  filet mignon roast, or beef tenderloin.

  • If you are not sure, just ask the butcher.

  • Butchers often tie tenderloins up with string so that it is the same thickness all the way around.

  • If yours comes that way, leave the string on until after it’s cooked.  If it doesn’t, no worries – no need to do anything.  

What kind of Thermometer should we use?

  • Use a good meat thermometer when roasting, especially if you prefer your tenderloin to be rare or medium-rare, instead of medium, or medium-well. 

  • It will take the guesswork out for you, and to be on the safe side, you should use one anyway because all ovens are different and will vary with temperatures and length of time to cook. 

What is the PREP WORK before cooking this filet mignon roast?

  • As always, before you begin, remove the tenderloin roast from its package and allow it to rest on your counter at least 30 minutes before roasting. 

  • Then season it generously with salt, black pepper, and garlic powder and follow the directions below in our recipe card.

How Long do you Cook the Filet Mignon Roast?

  • The standard for cooking a filet mignon roast is usually about 15 to 20 minutes per pound.

  • And with that, we always recommend you use a good meat thermometer and keep an eye on it towards the end of its cooking time.

How Long Does the Filet Mignon Roast Need to “Rest” Before Carving?

  • It’s best to allow the roast to rest for at least 5 to 7 minutes before carving.

  • However, keep in mind, as the roast sits and rests on your cutting board, the internal heat will continue to cook the meat.   So don’t let it sit too long, or you could have the majority of it well done.

  • Also, if you cut into the roast too quickly, and do not let it rest for a few minutes, it could cause the roast to lose all of its juices.

How Many Pounds of Roast Do I Need?

  • If the roast is the main feature of the meal and you decide to pair it with a few side dishes, then we recommend about 1/2 pound (about 8-ounces) or more per person.

  • And, it is a good idea, to calcucate and buy one additional pound than the number of guests you will be serving, just to be on the safe side.

  1. Do you have a recipe for Filet Mignon without the prosciutto onions? I have a 4 lb filet mignon roast i jsut need to know how long to cook andwhat temp?

    1. Hi Nancy! You can follow the same directions in our recipe card, and omit the prosciutto and onions. To cook a 4-pound roast, it’s usually 15 minutes per pound at 350 degrees, and it’s best to use a meat thermometer to roast to your preference.

  2. Hi there…this sounds absolutely scrummy! When you rotate, I take it the prosciutto remains on the bottom or does it stick to the roast? As well with the onions, do you simply place them back on top of the roast after the rotation? Do you think instead of prosciutto could one use pancetta instead?

    1. Yes Darrin, you can use pancetta with the roast and yes you can place them back on top after you rotate the roast. Hope this helps!! Enjoy!

    1. Rotating the roast, means to turn it over to brown all sides evenly while roasting in the oven. I prefer turning it a few times on the rack, turning a 1/4 turn- (rotating the roast) every 30 minutes or so. Makes the outside crusty while it helps cook the meat evenly . I hope this helps. Thanks for asking.

    1. Hi A! You don't have to do anything with the onions or prosciutto l, the tenderloin will absorb their flavors while cooking and will give flavor to the juices under the meat. Sometimes we spoon some of the crispy prosciutto along with the juices over the meat before serving.

  3. This is exactly why I will never be a vegetarian. I could live without burgers and other meat products – but slice a pink steak like this and I start to drool! This is beautiful. We always do a tenderloin roast for Christmas and your recipe sounds terrific! Thanks – have a blessed Thanksgiving.
