How to prepare your beef tenderloin
It’s important to properly trim and tie up your beef tenderloin before cooking.
Trimming and tying help keep the shape of the tenderloin even throughout so that it cooks evenly in your air fryer and stays juicy throughout.
To trim your beef tenderloin:
Locate the shiny, whitish-gray connective tissue.
Using a sharp knife, carefully slide it under the skin in between the connective tissue and the meat.
Make slow, long strokes with your knife, cutting away the connective tissue, while pulling it back. (Be sure to stay as close to the connective tissue as possible and don’t cut down into the meat!)
Repeat until you reach the end and discard the connective tissue.
To tie your tenderloin:
Your ultimate goal here is to make sure it’s an even cylinder shape. We will be cinching it together in one to two-inch intervals with twine.
Take about 12-15 inches of twine, and begin on the left side of the tenderloin, loop it around and tie a knot using the end of the twine.
This is your anchor knot.
Now take the rest of the twine, create a loop, and loop it under the tenderloin about 1-2 inches down from your anchor knot, pull it taught.
Keep creating loops and putting them every 1-2 inches down until you reach the end of the tenderloin.
You could skip these two steps and ask your local butcher to do this for you! They will trim and tie your beef tenderloin for you, free of charge.
What is an air fryer?
An air fryer is basically a tabletop convection oven.
It mimics the outcome of a deep fat fryer but without the use of oil. Hot hair is moved around via a fan that quickly and crisply cooks up the food.
The 2 most common air fryers you’ll see are basket style (that is what I have) or convection/toaster oven style.
There are pluses to both but I personally prefer my basket style.
What is the best air fryer to buy?
My biggest tip when it comes to air fryers is to make sure you pick a style that will work the most for your family and the amount of food you will be cooking.
My large basket-style air fryer can cook up to 12 wings, 2-4 servings of french fries, etc. which works well for my household.
Storage and leftovers
Any leftover air fryer beef tenderloin can be stored in an airtight container in the refrigerator for up to 3 days.
To reheat, simply place in a microwave-safe dish covered loosely with a damp paper towel and heat for 2-3 minutes or until heated thoroughly.
