When a friend shared with me how to cook filet mignon at home, I didn’t believe her at first that it could be that easy. After all, a perfect filet mignon steak is one of the most expensive dishes you can get at a restaurant – and one of my favorites. Then I heard it from a couple more people that it’s quick and simple to do. I knew I had to try a pan seared filet mignon recipe for myself!
My love for cast iron filet mignon started several years ago. The Twin Cities have a wonderful event a few times a year, called Restaurant Week. For a whole week, participating high-end restaurants all offer three-course meals for only $30! My first really good pan seared filet mignon was at The Capital Grille during restaurant week. We still enjoy it a few times a year, almost always during restaurant week because it’s more affordable.
Then, in 2014, we took a weekend trip to Chicago. And, it’s no secret that Chicago has some of the best steakhouses in the country. I knew we had to splurge and try one of the best ones! Our experience turned out to be quite a story…
What Is Filet Mignon?
Filet mignon is the best steak out there! It’s a smaller cut from the beef tenderloin, which is lean and tender.
And today, I want to share the best way to cook filet mignon with you!
How To Make Filet Mignon (The Best Way!)
So, what’s the best way to cook filet mignon? The key is 2 simple steps:
- Sear it over high heat in a cast iron pan.
- Finish the filet mignon in the oven.
The great news is, this all takes less than 15 minutes.
But if you want a perfect filet mignon recipe, read on for all my tips! But first, that story…
My Memorable Filet Mignon Story
I haven’t talked about travel very much yet on Wholesome Yum, so you may not know that it’s one of my favorite things in the world to do. Like, traveling and my kids are the two things that I live for!
In Chicago, the best food definitely had to include the best filet mignon. My research showed that several places tied for the best steak in Chicago. Even though I was booking over a month in advance, many were already full.
I made at a reservation at Chicago Cut Steakhouse, which had lovely views on the river. I even read that high-profile celebrities, like Beyonce, have been spotted there! (Just to be clear, this post is not sponsored by The Capital Grille or Chicago Cut Steakhouse. They don’t even know I exist. I just love a good steak!)
When my husband and I got to the steakhouse, we were seated by the window with a view. After we ordered, the owner (!!) of the restaurant came over and asked us if we would be willing to switch tables. He said that some VIP guests were unexpectedly coming, and for our trouble he would pay for our entire meal and bring us a bottle of champagne.
Having such an expensive meal entirely paid for was way too good a deal to pass up, so we agreed. We were even more surprised when the owner came back with an aged bottle of Cristal champagne! That alone was worth hundreds of dollars!
As we enjoyed our meal (and the filet mignon was ah-mazing and cooked to perfection!), we were incredibly curious to see who the VIP guests would be. Unbelievably, they never showed up! Ha.
Needless to say, we were more than glad to switch tables in exchange for a free steak dinner and expensive champagne.
How To Cook The Best Filet Mignon at Home
Having tried some pretty amazing steakhouses, I wanted to make sure to get the filet mignon recipe I’m sharing just right. Use the following tips, and you’ll have the best filet mignon every time:
1. Choose Quality Beef Tenderloin
As it turns out, by far the most important thing to get right is getting a fresh and high quality cut of meat. You want it to be thick and bright red, with minimal marbling. Two inches thick is great! A butcher is your best bet for getting an excellent cut, but Whole Foods and Costco also have decent options.
There’s no doubt that beef tenderloin is expensive, but when you compare it to restaurant prices, it’s actually quite reasonable. Where I live, the price ends up in the realm of $10-$15 for a large beef tenderloin, versus $50 or more at a high-end steakhouse. If you think about it, cooking filet mignon at home costs about the same as a burger at a cheap sit-down place!
2. Trim the Edges
Beef tenderloin is naturally lean, but it often comes with a layer of connective tissue along the edges. Make sure to cut this off for the best texture.
3. Season Liberally
Don’t be afraid to season your steak liberally with salt and pepper! No other seasonings are necessary, though garlic powder and dried herbs can be added. If there’s one thing to know about cooking filet mignon, it’s that the quality meat is the star.
That being said, I didn’t add enough salt the first couple of times (not good!) and it had a big impact. You need more salt than you probably think, so keep that in mind.
4. Use High Heat
High heat is absolutely critical to getting a good sear on your steak or steak bites appetizer. The best way to do this is in a pan that heats up to a very high temperature, so put away that non-stick cookware.
What you need is a cast-iron pan like this one. It makes an enormous difference! Plus, it allows you to finish the filet mignon in the oven after pan searing, which is an important step.
5. Time It Right
After your perfect filet mignon gets a nice sear on the stove, finish it in the oven to achieve the right level doneness. Everyone’s preferences are different, but I highly recommend cooking it medium rare, or at least no more than medium. This is a very lean cut of meat, so it will be dry if you overcook it.
How Long To Cook Filet Mignon In The Oven?
Use a meat thermometer to test your filet mignon recipe for doneness. Do not cut it open to check!
The following is a guide for how long to cook filet mignon in the oven:
- Rare – 125°F (~5 minutes for a 2″ thick steak)
- Medium Rare – 130°F (~6 minutes for a 2″ thick steak)
- Medium – 140°F (~7 minutes for a 2″ thick steak)
- Medium Well – 155°F (~8 minutes for a 2″ thick steak)
TIP: The meat temperature will rise another five degrees as it rests (see #6 below). The guidelines above are the temperature that the steak should be when you take it out of the oven, before resting.
6. Let It Rest
You may be impatient to cut into your steak immediately after cooking, but don’t do it! All the juices will spill out onto the plate and you’ll end up with a dry steak.
Instead, letting the steak rest for a few minutes will let the juices re-absorb into the meat, leaving you with the juicy filet mignon that you want.
7. Keep It Simple
A perfect filet mignon recipe means that the steak stands out on its own! You really don’t need to douse it in steak sauce or anything.
For beef filet mignon, I love it with fresh garlic herb butter, as in the recipe below. Sometimes people add a crust or make it Oscar style with crab meat. More often than not, you’ll find that simple is best if the beef tenderloin is seasoned and cooked well.
That’s it! Are you ready to make the best filet mignon at home?

Mash together half of the butter (1 tablespoon, 14 g), rosemary, thyme, and garlic. (Sprinkle in a little sea salt if using unsalted butter.) Form into a log and refrigerate until the last step.
Preheat the oven to 400 degrees F (204 degrees C).
- Trim any connective tissue around the edges of the beef tenderloins. Season the filets liberally with sea salt and black pepper on both sides.
Heat the cast iron skillet over medium-high heat, until the skillet is very hot. Melt the remaining butter (1 tablespoon, 14 g) in the skillet.
Add the filets. Sear for 2 minutes on each side, without moving them around.
Transfer the skillet to the preheated oven. Bake to desired level of doneness. (I recommend medium rare.) For a 2 in (5 cm)thick filet, that is 5 minutes for rare, 6 minutes for medium rare, 7 minutes for medium, or 8 minutes for medium well. Use a meat thermometer to check for the right temperature - 125 degrees F (52 degrees C) for rare, 130 degrees F (54 degrees C) for medium rare, 140 degrees F (60 degrees C) for medium, and 155 degrees F (68 degrees C) for medium well. The temperature will rise by another 5 degrees F while resting (see next step).
Remove the filets from the oven and transfer to a plate. Top each with 1/2 tablespoon (7 g) of herb butter (slice the log of herb butter into four parts and put one on each steak). Let the steaks rest for 5 minutes before cutting.
Serving size: 4 oz, or 1/2 of an 8-oz filet
