Season the chicken breasts with salt and black pepper.
Preheat your air fryer to 375°F (190°C).
Place the seasoned chicken breasts in the air fryer basket. Brush them with olive oil.
Air fry the chicken for 15-20 minutes, flipping them halfway through until they are cooked and have a golden brown exterior. The exact cooking time may vary depending on the thickness of the chicken breasts.
While the chicken is cooking, prepare the creamy sauce. In a skillet or frying pan, melt the butter over medium heat.
Add the finely chopped onion and minced garlic. Sauté for 2-3 minutes until the onion becomes translucent.
Stir in the cherry tomatoes, dried basil, dried oregano, and red pepper flakes. Cook for another 2-3 minutes until the tomatoes start to soften.
Pour in the heavy cream and chicken broth. Stir and let it simmer for about 5 minutes to thicken the sauce slightly.
Reduce the heat to low, and stir in the grated Parmesan cheese until the sauce is creamy and the cheese is fully melted. Season with salt and black pepper to taste.
Once the chicken is done in the air fryer, remove it and place it on serving plates.
Pour the creamy sauce over the cooked chicken breasts.
Garnish with fresh basil leaves, if desired.
