FAQs
Can I make this ahead of time?
Yes! Make the sauce a day ahead. Refrigerate and reheat in the roaster, adding pasta just before serving.
Can I freeze the leftovers?
Freeze the sauce without pasta for best results. Pasta tends to get mushy when frozen.
What size roaster do I need?
A 16–18 quart electric roaster works perfectly for this quantity.
How do I keep it warm during a party?
Set your roaster to “warm” and stir every 20 minutes. Keep the lid slightly ajar to avoid overcooking the noodles.
