To a pot add butter, onion, celery, and carrots. Saute that for about 5 minutes.
Add in garlic, salt, black pepper, paprika, onion powder, garlic powder, crushed red pepper flakes, and ground mustard. Saute that together for 1 minute.
Add in the better than bouillon chicken base, give that a stir, then shake over the flour, and whisk continuously for 2-3 minutes.
Next deglaze the pan with the chardonnay, whisk that for a minute, and let that simmer for a few minutes so the alcohol can burn out.
Then pour in the water, whisk that together for a few minutes, and bring the pot to a boil.
Once the pot comes to a boil, add in the chicken breasts, cover the pot halfway with the lid, and let it boil for about 15 minutes or until the chicken reaches the internal temperature of 165°F.
Once the chicken is fully cooked, remove it from the pot, shred it up, and add it back to the pot. Then add in the heavy cream, stir everything together, and bring the pot back to a boil.
Once the pot comes to a boil, add in the gnocchi, Pecorino Romano, spinach, chopped fresh parsley, and more salt & pepper (if needed). Stir everything together and let it cook for 3-4 minutes. Then you're ready to serve!!!
