Once the pan and oven have finished pre-heating, add your fries to the pan. The oil may sputter a bit, so be careful. If too much time elapsed between you squeezing your fries dry and the oven heating, you might have to pat them dry again, just to remove any moisture that may have risen to the surface. Toss the fries so that they all get covered in the oil then place the pan back in the oven. Check on them after about 10 min, stirring them around. They will take a while to cook and do need a little looking after, as you want to get them toasty on each side.
If you love french fries and live in Seattle but squirm at the idea of making your own, I recommend giving Bastille's Frites a try. They are a great happy hour accompaniment. Just make sure you don't go Fri-Sun (their kitchen has a little trouble in keeping up with the weekend volume and the fries suffer for it).
Spring is here and Summer is on its way, so now is the time to perfect your own fry recipe before grilling season starts!
