Frying them will get them crispy. That is how restaurants get them so crispy. Or, you could roast them fairly high heat 375 to 425 in the oven on a rack so they drain while they cook. Just keep a close eye on them and flip them over about half way, taking them out when they are as crispy as you want. Either way you choose, get them crispy first and just put some sauce on at the end. You can use a brush, or put them all in a bowl and toss them with whatever sauce you like, then serve.
