Preheat your air fryer to 375°F for 5 minutes and grease the air fryer basket.

Rinse the Cornish hen under cold water and pat it dry with a paper towel, drying the inside cavity as well.

Whisk together the salt, garlic powder, black pepper, thyme, and oregano.

Rub the olive oil all over the Cornish game hen and sprinkle the seasoning blend evenly over the bird.

Place the seasoned game hen in the preheated air fryer basket, breast-side down, and cook for 20 minutes. Flip and cook for an additional 10 minutes.

Insert a meat thermometer into the breast of the bird; it should read 165°F. If not, cook for 5 more minutes and check the temperature again.

Once the Cornish game hen is fully cooked, remove it from the air fryer and let it rest for a few minutes before slicing and serving.
