Start by boiling chicken broth in a pot and adding your penne. Give it a gentle stir and let it simmer until the pasta's cooked just right—al dente. This adds flavor, making everything more savory. Avoid overcooking the pasta to ensure it stays firm later.
In a large skillet, heat some avocado oil over medium heat. Add the butterflied chicken seasoned with Italian seasoning, paprika, salt, and pepper. Cook until golden brown, smelling fantastic and looking crispy on the outside. If you overcrowd the pan, the chicken will not brown properly.
Remove the chicken and toss in diced onions and minced garlic to the same skillet. Sauté until the onions are sweet and translucent, about five minutes. This fragrant mix adds a nice depth to your dish. Watch closely—garlic can burn easily if you leave it unattended.
Return the chicken to the skillet and pour in the cooked pasta along with some of that savory chicken broth. Stir in the heavy cream and parmesan until everything is well-coated and a little bubbly. The sauce should feel creamy and luxurious. Be careful not to let the sauce boil too vigorously; otherwise, it might separate.
Once the sauce is ready, sprinkle chopped parsley on top for a fresh touch. It should look bright and inviting. Serve right away to enjoy the creamy goodness while it is hot!
