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.
- Tie Individual Strings: Lay out about 6 individual strings 1-inch apart. Place the roast over your strings and tie each string tightly around the roast.
- The Loop Method: Tie a string securely over one end and secure tightly with a knot. Loop the string around your left hand then transfer that loop over the roast. Continue looping every inch of the roast and keep the string tight as you go. Secure the end with a knot and cut off excess string.

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:
Filet mignon is sliced from the center of the whole beef tenderloin. It is the most tender portion of the tenderloin which is why it is more expensive per pound.
The beef tenderloin, also known as “filet of beef” is considered to be the most tender cut of beef.
As a general rule of thumb, expect to serve about 5-6 oz (raw weight) per person. Keep in mind beef will shrink 25% during cooking. A 2 lb roast will feed 6 people. A 4-pound roast will feed 12 people.
The middle section of a whole tenderloin is known as the chateaubriand or center-cut tenderloin. Since it is an even cylinder shape, it cooks more evenly.
When cooking at 500˚F, make sure your oven is very clean. Also make sure meat is at room temperature, use a heavy-bottomed oven-safe pan, and a high-heat cooking oil (we use extra light olive oil). Also, keep the roast in the center of the oven and not too close to the heating element. When roasting on high heat, there will be some smoke but these tips will keep it to a minimum so you don’t set off your smoke detector.

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)

I hope this beef tenderloin roast with creamy mushroom sauce becomes a new favorite for you. Wishing you and your loved ones a delicious and beautiful holiday season.
What to Serve with Beef Tenderloin:
- Mashed Potatoes – you can’t go wrong serving beef and that mushroom sauce with creamy mashed potatoes.
- Roasted Carrots or Brussels Sprouts – simple and elegant sides
- Roasted Sweet Potatoes and Bacon – a family favorite
- Horseradish Sauce – this is perfect with beef tenderloin or beef in general. We love it with Prime Rib.

Instructions
How to Roast Filet of Beef:
- Preheat oven to 500˚F with rack in the center of the oven. Pat dry your room temperature tenderloin with paper towels. Tie tenderloin with kitchen string.
- Combine 2 minced garlic coves, 1/2 Tbsp thyme, 1 1/2 tsp salt and 1 tsp black pepper and rub all over roast. Drizzle generously and rub all over with 2 Tbsp olive oil.
- Place into an oven-safe roasting pan or skillet. Insert oven-safe thermometer into the deepest portion of the roast and bake in a preheated oven at 500˚F for 28-30 in for medium doneness (135˚F to 140˚F) or to desired doneness (see roasting chart).
- Remove from the oven 5-10 degrees before the roast reaches your desired temperature (the temperature will continue to rise as it rests). Transfer roast to a cutting board, loosely tent with foil and rest for 15-20 minutes then slice. Meanwhile make the mushroom sauce.
To Make the Mushroom Sauce:
- Place a large heavy skillet over medium-high heat. Add 2 Tbsp butter and 1 Tbsp oil then add sliced mushrooms and onion and sauté together, stirring frequently for 5-7 minutes or until onions are soft and mushrooms are lightly browned.
- Add minced garlic, thyme, 1/2 tsp salt and 1/2 tsp black pepper. Stir together for 1 minute until fragrant then transfer mushrooms to a separate bowl.
- Add 1/2 cup wine and scrape the bottom to deglaze. Continue cooking until most of the wine has evaporated (2 minutes).
- Add 1 cup beef broth and boil until reduced by half (5-7 min).
- Stir in heavy cream and mushrooms, bring back to a boil then reduce heat and simmer another 2-3 minutes or until sauce reaches desired thickness. Season sauce to taste with salt and pepper.
Natasha, this is an absolutely wonderful recipe! One of mine and my husbands favorites. Thank you for all of your great dishes.
I’m so glad you enjoyed it, Denise! Thank you for the wonderful review
Natasha, I’m wondering if I was have 8 adults for dinner would you cook a 4LB roast? In your Video you said 2LBS of Mushroom and the recipe says one? I just want to make sure that it looks saucy and not all mushrooms… Thanks in advance…
Hi Ellen, if you click on the serving size in the recipe card, you can slide it up or down to scale the recipe ingredient lists. I hope that helps!
My sister and I made this recipe for Easter dinner today. It was so delicious! Our family loved it! Our favorite part about it was the mushroom sauce on top. This is our go-to Easter dinner recipe to have now in our life. Thanks for the recipe Natasha!
You’re very welcome, Zoie. Thank you for sharing your wonderful comments and review for this recipe!
hi,.
one of your other recipes for beef tenderloin calls for some bacon grease brushed on a couple times ,
would you do that with this rub ? thx !
Hi Toby, that may work! If you experiment, let me know how you liked the recipe.
Fabulous ! I rubbed the roasts with your herbs and salt and pepper and olive oil , then
cooked 6 slices of market thick bacon , and brushed the roasts with the bacon grease And let them set over night to marinate. Cooked following your thermometer @ 130 degrees.
The bacon bits we used on Romain wedge salads . Best Tenderloin ever , Thanks !
Thank you so much for sharing that with me. I’m so glad you enjoyed it!
I have made your mushroom sauce twice. The first was two weekends ago when I made the Tenderloin meal, the second was last night when I made it with chicken schnitzel. It was amazing and plate licking worthy. Your recipes are easy to follow. Thank you 💙.
I’m very happy to read your comments and good review, Rob. Thank you for sharing that with us!
OMG i have never made a roast tenderloin before with this amazing mushroom sauce but we are completely in love.
thx so much for this amazing recipe followed every single step to perfection
You are very welcome, Karin! I’m glad it was a success and you loved it!
Could the tenderloin be cooked ahead and served at room temperature?
Would like to serve with small rolls with horseradish sauce.
Hi Sally, I haven’t tested that but I think it could work well.
Would LOVE to try this! However…..I. Don’t. Do. Mushrooms. At. All. Any substitutions?
Hi April, we love the recipe with mushrooms but I think it would still work without it. Please share with us how it goes if you try this recipe without the mushrooms.
Thank you! I will let you know how it comes out!
Your roast looks delicious. Would you cook any roast at 500 degrees. I don’t have good luck with roasts. Help
Hi Rosalie, that would depend on the roast but we found this works for this one well.
Made this tonight. Absolutely fantastic. New family favorite. Simple and delicious. You are a marvel Natasha…. I am Ukrainian and appreciate your slant on good food!! ⭐️⭐️⭐️⭐️⭐️
Hello Leah, thanks for sharing your good feedback with us. I’m glad your family loves this recipe!
Hello,

Thank you!
I’m so glad you enjoyed it!
Made this for our Valentine Supper. This was outstandingly melt in your mouth awesome. Cannot say enough. The mushroom sauce is to die for folks. Love your fun video classes on how to make the recipes and your helpful hints to success. Thanks so much Natasha.
Hello Karla, you are very welcome. I’m so glad you enjoyed this recipe, thank you for sharing your great review with us!
That’s just awesome! Thank you for sharing your excellent review, Karla!
I am confused about how much mushrooms to use in your mushroom sauce recipe. The ingredient list calls for 1LB. In the video however, Natasha says to thickly slice 2LBs. So which is it, 1 pound or two?
Hi Brian, I would recommend following the recipe always as we can update the recipe but the video cannot be updated.
Delicious and easy to cook.
A wonderful meal. Highly recommend. Made this for our Valentine dinner. Exceeded expectations!!!
Love it! Thank you for your recommendation and great review, Eva.
Made this last night for my husband’s birthday – sensational!
Great to hear that, Karen. Thank you!
Hi Natasha, I love your recipes! I was wondering since its just my husband and me what size roast should I get? I know I could just make steaks but I really want to try this recipe. Could I cut it in half and save the other half for another time? Would that effect the cooking time?
Hi Debbie, that should work to make half of the recipe and since the meat thickness would be roughly the same, the roasting time should be very close. I still highly recommend using a thermometer to double-check since not all roasts are the same thickness.
Love your recipes. Can you tell me the brand and model of your meat thermometer. I’ve been looking for a wired one that can stay in the oven while cooking.
Hi Barry, absolutely! This oven-safe thermometer HERE is our go-to.
This was amazing! A bit late on the review, but made this for new years and it came out incredible! The butcher tricked me and gave me the end piece so next time I’ll be sure to ask for the middle piece but it was still so tender and juicy I just can’t say enough good things. Even my mom loved it and she hates steak.
That’s just awesome! Thank you for sharing your wonderful review!
quick question – receipe says 16 oz mushrooms but on video you said 2 pounds, which is correct ?
Hi Anthony, the written recipe is correct. I miss-spoke in the video and I can’t undo that, but the full written recipe is accurate.
went with 25oz of mushrooms and that was fine – lots of yummy sauce. Struggled with finding tenderloin that looked anything like the one you were using. In Australia its known as eye fillet and very expensive. I substituted a Topside roast which seemed to work quite well with the rub – awesome receipe 🙂
I’m glad you were able to find a good substitute, Anthony. Thank you for your great feedback!
In Australia ,your roast is called a scotch fillet. An eye fillet is the Centre of the fillet as you explained. Topside roast is a good substitute though.
Amazing- we made this tonight to celebrate Monday! 😊♥️ Amazing recipe – it was delicious. Everything I’ve made that you have posted has been unbelievable. Thank you for being such a great chef!!
Thank you for the wonderful review!
