Tips
Use freshly grated cheese instead of pre-shredded for smoother melting and better texture in the sauce.
Don't skip making the roux - it prevents the cheese sauce from breaking and ensures creamy consistency.
Let the mac and cheese rest for 5 minutes after baking to allow the sauce to thicken before serving.
Good to Know
Refrigerate covered for up to 3 days. Reheat in 350°F oven covered with foil until warmed through.
Assemble completely without breadcrumb topping, cover and refrigerate up to 1 day. Add breadcrumbs and bake when ready to serve, adding 5-10 minutes to cook time.
Serve hot immediately after resting. Pairs well with simple green salad or roasted vegetables.
Common Mistakes
