The prep for this recipe is easy and fast--it takes less than the time to heat the oven. The hard part of this recipe is making sure not to overcook your potatoes--I had a few pieces that weren't as uniform as the others that burned--and mine were probably mostly ready after exactly 45 minutes.
I also recommend reducing the salt. I used the 2t the recipe called for and we all agreed less salt would've been better, you can always add more later.
