Tips
Cook pasta just until al dente since it will continue cooking in the oven and absorb sauce moisture.
Let the alfredo sauce simmer until it coats the back of a spoon for the perfect creamy consistency.
Cover with foil if the top browns too quickly during baking, then remove foil for the last few minutes.
Good to Know
Refrigerate leftovers up to 3 days. Reheat in microwave or oven until heated through.
Assemble up to 1 day ahead and refrigerate covered. Add 10-15 minutes to baking time if baking from cold.
Let rest 5 minutes after baking before serving to allow sauce to set slightly.

Don't overcook the pasta initially to avoid mushy texture after baking
