Cook the pasta according to package directions.
Peel, core, and slice the pears into ¼-inch slices. Cut them into julienne strips, then halve for bite-size pieces.
Melt butter in a large skillet. Add pears and sauté 2–3 minutes over medium heat, until slightly tender and juicy. Use a slotted spoon to remove pears and set aside, leaving juices in the pan.
Add chicken broth, salt, and pepper to the pan. Bring to a simmer.
Whisk the cream and cornstarch together, then pour into the pan. Return to a simmer and cook 1–2 minutes until lightly thickened.
Add cranberries and cook 30 seconds.
Remove from heat and immediately stir in the Gorgonzola, Parmesan, parsley, and cooked pasta. Toss until the cheese begins to melt and coat the noodles.
Add chicken, pears, and turkey bacon (if using).
Top with pecans right before serving, plus extra Parmesan, parsley, or bacon crumbles.
