Place the chicken in a pot of water and bring to a gentle boil. Cook for about 15 minutes until the chicken is fully cooked. Remove the chicken and shred it using two forks. Toss the shredded chicken with the blue cheese dressing and set aside.
In a large high-walled skillet, melt 1 tablespoon of butter over medium heat. Add the diced onions and celery and cook for about 5 minutes until softened.
Add the minced garlic and cook for 1 more minute.
Pour in the undrained diced tomatoes and chicken broth. Bring the mixture to a boil and add the penne pasta. Submerge the pasta into the liquid and allow it to come back to a boil. Cover and let the pasta cook for 10-13 minutes, stirring occasionally, until al dente.
Reduce the heat to low and add the buffalo sauce, cubed cream cheese, and shredded cheddar and mozzarella cheeses. Stir gently until the sauce is smooth and the cheese has melted.
Add the shredded chicken and optional red pepper flakes. Stir well to combine.
If desired, swirl in 2 tablespoons of cold butter for a smooth, glossy finish.
Once the sauce has thickened to your liking, remove from heat and serve immediately.

Store leftovers in an airtight container in the refrigerator for up to 3 days.
Reheat in a skillet over low heat, adding a splash of chicken broth or milk to loosen up the sauce.
For extra heat, increase buffalo sauce or add extra red pepper flakes.
Substitute the pasta with gluten-free pasta for a gluten-free version.
Freeze for up to 2-3 months. Reheat thoroughly when ready to serve.
