Whisk together chicken broth, cornstarch, salt, pepper, paprika, and italian seasoning.
Add pasta, milk, chicken broth mixture Add enough additional water to fully submerge everything. Bring just to a bubble, then cover pan and let cook for 20 minutes.
Remove lid and add heavy cream, parmesan cheese and red pepper flakes. Stir until fully combined. Let cook another 5 minutes. Then let rest away from heat for 5 minutes before serving (sauce will thicken up.)
