Pro Tips for the Perfect Healthier Broccoli Chicken Casserole
- Cook Pasta Al Dente: Slightly undercooking the pasta prevents it from becoming mushy while baking.
- Add Broccoli at the Right Time: Drop broccoli in during the last minute of boiling so it stays bright and crisp.
- Use Fresh Cheese: Shred your own cheddar for smoother melting and richer flavor.
- Don’t Skip the Dijon: A small spoonful adds depth and balances the creamy sauce.
- Finish with Broil (Optional): For a golden cheesy top, broil the casserole for 2 minutes after baking.
