I have lots of experience with cooking and with roasters. It would be helpful to know what you plan to use the roaster for. I use cooking bags in mine because it maintains the moisture and easier to clean. Moisture is key when using them because they do tend to be hotter on sides so liquid evaporates. This being said, I love my roasters for cooking for crowds and at church;we would be lost without them!
Potatoes- I use a party potato recipe with cream cheese, sour cream, butter, half and half which makes them creamier and they hold up to warming in crockpot or roaster. Make sure they are not too stiff or they will dry out.
A turkey in a cooking bag cooks very fast in a roaster and remains moist.
For the rolls I would keep them in tinfoil with a little opening so they do not get soggy. Keep the roaster on a low setting.
Let me know if you have any questions. Dianne
