Description

Air fryer porterhouse steak comes out tender, juicy, and steakhouse-quality in about 15 minutes — with a seared crust and a perfectly pink, rosy center every time.

Ingredients 

  • 2 porterhouse steaks, about 1–1.25 lb each, at least 1.25 inches thick
  • 2 tablespoons butter, plus more for resting
  • 1½ teaspoons kosher salt
  • 1 teaspoon freshly cracked black pepper
  • Optional: 1–2 teaspoons steak seasoning; 1 clove garlic + fresh rosemary or thyme

Instructions

  • Remove steaks from the fridge 30–45 minutes before cooking. Pat completely dry with paper towels.
  • Rub each steak with a little butter, then season both sides generously with salt and pepper (and steak seasoning, if using). Press it in.
  • Preheat the air fryer to 400°F for 5 minutes. Lightly grease the basket.
  • Place steaks in a single layer with space around each. Top each with a thin slice of butter. Cook 5–7 minutes, flip, and cook another 4–6 minutes.
  • Insert a thermometer into the thickest part, away from the bone. Pull at 130°F for medium-rare (see chart for other doneness levels), about 5°F below your target.
  • Transfer to a cutting board, top with a fresh pat of butter, and rest 5–10 minutes. Slice the strip and filet off the bone, cut across the grain, and serve.

Equipment

Notes

Doneness Pull Temps (pull ~5°F early for carryover)

  • Rare — 120°F (final 125°F)
  • Medium-rare — 130°F (final 135°F) — recommended
  • Medium — 135°F (final 140°F)
  • Medium-well — 145°F (final 150°F)
  • Well done — 150°F+ (final 155°F+)

Notes

  • Thickness rules everything: add ~2 minutes per extra ¼ inch; subtract ~2 minutes for a 1-inch steak. For steaks under an inch, cook at 380°F.
  • Don't crowd the basket — cook in batches so the steaks sear instead of steam.
  • No thermometer = guesswork. It's the single best tool for perfect steak.
  • Works identically for a T-bone; check temp slightly earlier.
