Beef tenderloin, or filet mignon if you prefer, is a premium cut of beef that needs to be treated with care and attention. The name “tenderloin” isn’t accidental, these barely used muscles come from the loin portion of the cow and are the most tender cuts of beef available. The lack of fatty marbleisation in tenderloin makes it susceptible to overcooking. At it’s best it’s tender and flavourful, overcook it however and you’ll be left with a plate of dry disappointment. Cooking using sous vide and Suvie is the ideal way to get the best out of this steak. The precise control of sous vide let’s you cook the steak to the ideal level of doneness.
Follow this simple guide to prepare perfectly cooked beef tenderloin every time.
Temperature and cooking times for beef tenderloin
|130°F||1-3 hours||Medium rare|
|145°F||1-3 hours||Medium Well|
|150°F||1-3 hours||Well done|
Tenderloin is lean and has very little marbleization or fatty tissue, as a result, it’s more prone to drying out at higher temperatures. Keep this in mind when setting the temperature of our Suvie or immersion circulator.
In terms of timing, our recommended cook times are based on a 1 1/2 inch thick steak. If your steak is thicker than 1 1/2 inches consider adding about 30 minutes to the cook time.

Ingredients and Tools
- Beef tenderloin (at least 1 1/2 inch thick)
- Vegetable oil
- Herbs or additions
- Suvie or immersion circulator
- A large pot (if using an immersion circulator)
- Vacuum sealer and bags or freezer safe recloseable bags
- A heavy, preferably cast iron, pan
If you’re using a sous vide immersion circulator, pre-heat your water bath to the desired temperature.
Season the steak generously on all sides with salt and pepper.
Place the steak into the plastic bag along with any herbs or additions and vacuum seal. If you’re using a recloseable bag, follow our guide on the water displacement method.
Lower the bag into the water bath and leave until cooked.
If you are using Suvie place the bag into a Suvie pan and cover completely with water. Place in Suvie and use the following settings:
My Cook > Multi-Zone Settings
Protein: 125-150°F, 40 minutes-3 hours depending on the desired doneness (or follow our protein cooking guide)
Vegetable: 0 minutes
Starch: 0 minutes
Once the cook is done remove the bag from your Suvie or water bath.
Remove the steak from the bag and pat dry with paper towels.
Heat 1 tbsp vegetable oil in a cast-iron pan over high heat. Avoid using olive oil as it has a low smoke point.
Once the oil begins to smoke and shimmer, add the steak. and cook without moving for 15 seconds.
Flip steaks and repeat on the opposite side for 15 seconds. Continue flipping steaks in 15-second intervals until both sides are well browned.
Remove from heat and rest for 5 minutes.

Are the cooking temperatures safe?
Our recommended cooking temperatures for Sous vide and Suvie are lower than what the USDA recommends, however, cooking times and temperatures are long enough and high enough for “pasteurization” to make your food safe. The USDA recommendations indicate the temperature needed to instantly kill food pathogens. By cooking for a longer time at a lower temperature we are able to achieve the same effect. However, high-risk populations should use extra caution when preparing foods below the USDA recommended temperatures.
Where can I get vacuum sealed proteins?
If you don’t want to fuss with vacuum sealers and recloseable bags you can skip the store and order the Suvie Protein Box. Just put together your ideal combination of preseasoned, portioned, and vacuum-packed high-quality meat, poultry, or fish. We deliver it to you frozen in a carefully-packed box.
Can I use any type of plastic bag?
You can, however, make sure that they are made from polyethylene. Brand name recloseable bags are made using polyethylene which is a BPA and dioxin free plastic that can safely handle sous vide cooking temperatures up to 190°F. Some generic branded plastic bags are made using cheaper polyvinyl chloride (PVC) which cannot handle high temps and contains chemicals that can leach into food.
Should I leave my steak to rest before serving?
Nope! One of the great things about cooking with Suvie and sous vide is the evenness of temperature. While the outer edges will be hotter from the sear, the interior of the steak will be cooked to the same temperature throughout. This means no resting time is necessary.
I forgot to defrost my steak, what now?
No problem! You can sous vide steak directly from frozen. Just add 1 hour to the cooking time.
Can I cool my steak after the sous vide process and sear it later?
For food safety and general food quality reasons, we don’t recommend it. Steak should be seared and eaten soon after the sous vide step.
Can I leave my steak in the water bath indefinitely?
You can, but you shouldn’t. While leaving steak in sous vide for long periods of time won’t result in overcooking, it will have a negative effect on the overall texture of the meat.
