Step 1: Cook the Chicken. Preheat your oven or air fryer to 180°C (350°F). Season the chicken fillets with oregano, black pepper, garlic powder, and salt. Place them in the oven or air fryer and cook for 20-25 minutes until fully cooked.
Step 2: Cook the Pasta. Boil the pasta in salted water according to package instructions. Once cooked, drain and set aside.
Step 3: Prepare the Sauce. In a large skillet, heat a splash of oil and fry the sliced red onion and mushrooms until softened. Add the lazy garlic and cook for 30 seconds.
Step 4: Add the Liquids and Cheeses. Pour in the chicken stock and let it simmer for a few minutes to reduce slightly. Stir in the pesto, then add the Philadelphia cream cheese and half of the mozzarella. Stir continuously until the cheese is melted and the sauce is smooth.
Step 5: Combine Everything. Slice the cooked chicken into strips and stir it into the sauce. Add the drained pasta and mix everything together until evenly coated.
Step 6: Final Touches. Divide the pasta into bowls, sprinkle the remaining mozzarella on top, and place under the grill for 2-3 minutes until the cheese is bubbly and golden.
Step 7: Serve. Enjoy your pesto chicken pasta with a side of steamed veggies or a fresh salad.
