Air Fryer, Whole Beef Tenderloin With Garlic Butter Sauce

This is a great steak. The air fryer really left the moisture in the steak, so we got a great whole roast beef out of the meal. It was one of my kid's favorite meals.

  • 2 whole beef tenderloins (about a pound each)
  • 4-5 tablespoons olive oil (for rubbing over the steaks)
  • salt and pepper to season the steaks
  • 1-2 teaspoons fresh rosemary, optional

Garlic Butter Sauce:

  • 1/4 cup butter
  • 4 teaspoons minced garlic
  • 1/2 teaspoon salt (or to taste)
  • 1 tablespoon lemon juice
  • 1 teaspoon minced fresh dill


  1. The first thing I do when making steak (I got this hint from one of Bobby Flay's shows) let the meat rest at room temperature for AT LEAST 30 minutes

  2. Start by preheating the air fryer, steak is one of the few recipes, that I preheat the air fryer for. But the meat will come out better, so turn the air fryer oven'/basket on for 5 minutes at 400 degrees F.

  3. Then rub the olive oil or butter all over the steak, and season with salt and pepper. I added some cut up rosemary over the steak, (but this is optional)

  4. Set the steaks in the air fryer for 6 minutes, then flip and air fry for another 6 minutes.

  5. Again, per Bobby Flay, let the steak rest for at least 5 minutes. 

  6. Plate, serve and enjoy! 

To Make the sauce:

  1. In a small saucepan mix together the butter, garlic, lemon juice, salt, to a low simmer, just enough to infuse the flavors together, then remove it from the heat and mix in the fresh dill, drizzle over the steak.
