Notes
Use any pasta you'd like. Just be sure to break up larger pastas for easier eating.
Don't overcook pasta. Boil pasta al dente to prevent it from getting mushy.
Make sure there is enough broth to cover the pasta. Feel free to add more as needed.
Adjust seasoning as desired. We recommend starting small and tasting along the way!
Keep an eye on the casserole under the broiler to make sure it doesn't burn.
