Ingredients

seared steak

  • 2 strip steaks
  • kosher salt
  • freshly cracked black pepper
  • 3 to 4 tablespoons unsalted butter

truffle herb fries in the air fryer

  • 2 to 3 russet potatoes, thinly sliced
  • olive oil for spritzing/brushing
  • 1 teaspoon truffle salt
  • 2 tablespoons chopped fresh parsley
  • 2 tablespoons freshly grated parmesan cheese

honey dijon aioli

  • cup mayonnaise
  • 1 garlic clove, minced
  • 1 tablespoon dijon mustard
  • 2 teaspoons honey

Instructions 

seared steak

  • Make sure your steaks sit out at room temperature for about 30 minutes.
  • Heat a cast iron skillet over medium-high heat - you want it hot! Season the steaks on both sides with the salt and pepper.
  • Add 2 tablespoons of butter to the hot skillet. It will sizzle and smoke and once it’s all melted, add in the steaks. Cook for 3 minute, until deeply golden, then flip and cook for 3 minutes more. Add in the remaining butter. Once it melts, spoon it over top of the steaks for another 1 to 2 minutes. I like to cook the steaks to about 140-145 degrees (almost medium doneness or medium well). Remove the steaks and let them rest for 10 to 15 minutes before slicing.

  • Place the sliced potatoes in a large bowl and cover with cold water. Let the potatoes sit in the water for 30 to 60 minutes. Remove the potatoes and place them on kitchen towels - you want them completely dry! Pat them as dry as you can!
  • Preheat your air fryer to 375 degrees F. Place the potatoes on a baking sheet and spray or brush with olive oil. Place the fries in a single layer in your air fryer (you might have to do 2 batches!). Cook for 12 minutes, then gently flip the fries and cook for 5 to 6 minutes more.
  • Stir together the parsley and parmesan cheese. When the fries are done, place them on a plate or a sheet of parchment paper and sprinkle all over with the truffle salt immediately. Sprinkle with the herbs and parmesan mixture. Serve with the aioli.
    If you do 2 batches, or if the fries are done before the steak, you can stick these in a 200 degree F oven until ready to eat!
