Help! How long do my roasted potatoes need?

[Scuba]

I'll be cooking up a porketta later today, and want to serve some roasted potatoes with it. I plan on cutting them into chunks approximately two inches square, putting them in a covered baking dish with some olive oil and popping them in the 350 degree oven at just the right time.

How long will they need? Any other advice?

1. About 30 minutes

You can use an instant read thermometer and the internal temperature should be 210F when they are done.
