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!).

Ingredients

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.

Variations

• 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.

1. Prep the filets:Let your filets sit at room temperature for 30 minutes before cooking. Then, pat them dry with a paper towel and sprinkle them on both sides with sea salt.

4. Move the pan to the oven:Place the cast iron pan with the pan seared filet mignon filets into the oven. Cook for 3-6 minutes, depending on how you like your steak.
5. Serve: Remove the pan from the oven, and serve the steaks while hot. Don’t forget to drizzle the butter from the pan over the steaks on the plate. Those juices are delicious!

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.
