Why can't I cook potato wedges correctly?

[Mintooo]

..in the oven?

I cut the potatoes into wedges, cover in olive oil and salt and pepper. 200 degrees in the oven for abojt 40/45 mins.
When they come out some parts will be burning and others will still be soft and not crispy! Where am I going wrong?

Ime the drier they are the better. Drying them off with some kitchen paper helps

I part microwave.
Cut, coat in oil and flavour (salt with smoked paprika and/or garlic granules usually) then a couple of minutes in the microwave until the pointy bit starts going translucent. Then into the oven.

Par boil a bit

Allow to dry

Cover with oil. Salt pepper

Turn frequently and move around the tray

I would micro the potatoes whole then cut after, if not they kind of seal up and dont go nice and crunchy
