Easy Cast Iron Filet Mignon Recipe

Over the years, I have learned that overthinking steak can be a major downfall. Steak is best when prepared simply. Not too much seasoning, not too much marinade, and definitely not too much time in the pan. Letting the real flavors of the filet mignon shine through is what makes this recipe so great.

I use sea salt and Herbes de Provence to season my steak. I cook the filet mignon in a mix of butter and olive oil. The cast iron pan is essential to cooking the steak evenly. It also helps you cook the steak to exactly the temperature you want (I’m a medium-rare kind of girl!).

This easy, straightforward way of making filet mignon makes a steak that tastes anything but basic.I will be putting a few pieces of filet mignon in mycast iron skilletthis Valentine’s Day as a special treat for my family. You should try it as well! This foolproof recipe is a wonderful special occasion meal that looks incredibly fancy but is something anyone can make.

See recipe card below this post for ingredient quantities and full instructions.

  • Filet mignon– Look for thick cuts of beef — a filet mignon should be about 8 ounces and 1 ½ to 2 inches thick.
  • Olive oil – If you’re worried about the oil smoking, opt for one with a higher smoke point like avocado oil.
  • Sea salt– I like to use sea salt because it has larger flakes which help draw out the juices of the meat.
  • Butter
  • Herbes de Provence– Herbes de Provence is a blend of thyme, savory, marjoram, rosemary, fennel, and basil. It is a great mix of herbs that goes well with the taste of steak. It is also a very simple way to add a bunch of herbs to your steak with just one shake of a bottle. You can find Herbes de Provence in any grocery store.


  • Replace the butter witholive oilto eliminate the dairy.
  • Replace the Herbes de Provence with some simplekosher salt and pepper.
  • Top the cooked filet mignon with ¼ cupgorgonzola cheese crumbsfor an extra salty, powerful flavor.

Recipe Tip

You can easily double this recipe, as long as you can fit multiple steaks in yourskillet. Make sure the filets are at least 2 inches apart so they have space to cook evenly. You may need to keep the pan in the oven for an extra minute or two to reach the desired internal temperature. You’ll create the perfect filet mignon!

How to Store Cast Iron Filet Mignon

Filet mignon is definitely best when eaten fresh out of the oven. However, if you do have leftovers, you can store them in an airtight container in the fridge for 3-4 days. To reheat the cooked filet mignon, put it in a 250ºF oven for 20 minutes. This will warm the filet all the way through and not dry it out.

You can also reheat filet mignon in the microwave. Be sure to turn your microwave to 50% heat then reheat the steak in 30-second increments, flipping it over every 30 seconds. Heating it on a lower power will help prevent the steak from getting dry or hard as it reheats.

Serving Suggestions

Pair this cast iron filet mignon with a simple side dish. Some of my favorite options include Instant Pot Mashed Potatoes,Roasted Asparagus, orAir Fryer Brussels Sprouts. It’s also great withCheesy Asparagus CasseroleorScalloped Potatoes.


How do I cook a 2-inch thick filet mignon?

This recipe is perfect for a 2-inch filet mignon. If your filet is this thick, sear it for 2 1/2 minutes in the skillet before flipping and placing the pan in the oven. Thirty extra seconds in the pan will help cook the thick steak perfectly.

Why is my filet mignon tough?

Filet mignon does not have much fat to help it stay juicy as it cooks. Cooking filet mignon too long at a high heat will make the protein strands in the meat tough and chewy.

It is best to cook filet mignon quickly and just to an internal temperature of 130-135 degrees Fahrenheit. This is not a cut of meat that tastes good when well done. If you like well-done steaks, opt for a fattier cut like a rib eye or NY strip steak.

Do you put olive oil on filet mignon?

I like to sear filet mignon in olive oil and then top it with butter. Cooking the steak in all butter can be overly rich, while all olive oil is a little too bland for my taste. The combination of butter and olive oil is perfect!
