The Cut: Filet Mignon
When it comes to the king of tender steaks, the filet mignon is it. This cut is famous for its fork-tender cut at steakhouses and fine dining establishments worldwide. Cut from the whole tenderloin, an underworked muscle on the back of the cow; it’s a lean cut with minimal marbling that is begging to be the center of the plate for romantic dinners and amazing date nights.
However, due to its minimal marbling, this cut suffers when cooked past medium and can dry out quickly. It also has a mild beef flavor, so pairing it with an amazing steak sauce recipe or rich compound butter to serve is always a great idea.
Why sous vide steaks?
Although we love a pan-seared filet mignon on busy nights, it’s the best steak for the sous vide method because the precise temperature-controlled water bath guarantees the steak cooks to the perfect temperature. This cooking method is the only way to get the exact temperature from edge to edge for the best results—mitigating the risk altogether of drying out the meat. It’s science!
This sous vide steak is finished with a quick sear in a piping hot cast iron skillet to add a nice crust and help the overall appearance of the beef.
And, yes, it seems fancy, and yes, it is fun to sound like a French chef; the sous vide cooking method is easy, even easier than grilled filet mignon. Once you set the sous vide bath with the immersion circulator and drop the vacuum-sealed steaks in, you can work on the sides. This method is perfect for thicker steaks and prime rib roasts. It also works great for sous vide beef tenderloin if you’re feeding a crowd.

How to sous vide filet mingon
- Start by patting the steaks dry with paper towels and secure the edges with butcher’s twine. This helps to retain their shape as they cook. Then place the steaks in a vacuum seal bag. We seal each individually with a vacuum sealer to ensure a good seal.
- Set up your sous vide cooker and the water bath for 120 degrees F. Let the water come up to temperature before adding the steaks in the vacuum bag.
- When the water is at 120F, place the steaks in the water bath, slowly to make sure no leaks appear. Cover them with a mesh weight to keep them submerged. Let the filets cook in the sous vide for 2 hours.
- Carefully remove the steaks from the sous vide water bath and bags. Discard the bags and pat the steaks dry again.
- Next, Season the sous vide filet mignon steaks liberally with salt (and if you feel like really going wild, add some of my umami powder to beef things up). Preheat a cast iron pan over medium-high heat.
- As soon as the pan just begins to smoke, add the butter and swirl to coat. Lay the rosemary and garlic in the pan. Gently place the steaks into the hot pan and sear.
- Without moving the steaks, baste them in the melted butter. And when a good crust forms, about 2 minutes, flip the steaks and repeat on the other side.
- Immediately transfer the steaks from heat to rest, remove the butchers twice, and add a pat of compound butter to each steak while it rests for 5 minutes. Then finally, serve it hot with your favorite steakhouse side dishes and a steak sauce.
Girl Carnivore Expert Tip
If the sous vide cooks the filet mignon steaks perfectly, why the sear? Right out of the water bath, they are the perfect cook, technically. But they don’t have the best appearance. The sear adds color to the meat but also a wonderful crust that gives each bite a elegant texture.

Steak sauces for filet mignon steaks
Because filet has a mild beef flavor, it’s best to boost the umami by pairing it with a delicious steak sauce recipe. Try some of our favorites, like red wine sauce for steaks, classic Bearnaise sauce, brandy peppercorn steaks sauce, or even a blue cheese steak sauce. Alternatively, a roasted garlic homemade compound butter recipe goes a long way with these delicious steaks too.
Set your sous vide machine to a temperature of 120 degrees F and let it bring the water to temperature before placing the steaks in. 120F will allow the steak to cook to a flawless even pink internal color from edge to edge and medium-rare filet mignon when served.
Set the sous vide machine 10 degrees below your desired doneness. Remember, the steak will continue to rise 10 to 15 degrees with carry-over cooking when seared and rested.
For a 1 1/2 inch filet mignon, sous vide the steaks for no longer than 2 hours. Because this is a naturally tender cut, anything longer than that risks the meat becoming too soft to be enjoyable. This makes for that signature ‘cut with a fork‘ tenderness without the beef getting too soft.
