Notes

Mary's Tips & Tricks

  • Dairy Free: If you need to make this recipe dairy-free, use vegan butter like Miyokos or Earth Balance. If you're Whole30, feel free to substitute ghee.
  • Batches: If you want to double the recipe, make your steak in batches so you don't overcrowd your air fryer. Follow the same directions for subsequent batches.

How to Pick the Best Filet Mignon

There are a few ways to make sure you choose the best cut of meat. 
  1. Pick a nice store! Maybe you have a local butcher shop, which is a great place to start. Otherwise, if you are going to the grocery store, choose one that has a nice meat department. Places like Wegman’s, Whole Foods, Sprouts, and other specialty stores might be a little pricier, but they also typically have fresh, high-quality meat on hand. 
  2. Choose USDA Prime or Choice cuts. These are going to be the top-quality cuts based on the USDA grading system. 
  3. Look for a center cut. This will be a little more expensive, but this choice really delivers a good cut of meat! 
  4. When in doubt, ask the meat department! Don’t be afraid to ask questions and pick the right steak. If you’re going to splurge on steak, it’s perfectly acceptable to ask for help so you know you’re picking the right cut.
