Wash and clean the potatoes. In a large pot bring enough salted water to a boil. Add cleaned potatoes and cook till done.(The potatoes should be just cooked, not mushy and overcooked)
Pre-heat oven to 200 degree celsius.
Drain the potatoes once cooked and let it cool down a little bit. If you want to roast potatoes without skin then remove them.( I have kept the skin on here).
Gently press the potatoes in-between both the palms to flatten them slightly or using the back of the fork.
In a big mixing bowl add all the melted butter and Cajun spice. Mix well.
Rub the spice mixture evenly on potatoes. Arranged spice coated potatoes on a baking tray. Drizzle little olive oil on top.
Bake for 20 minutes till the potatoes look crispy and roasted. Once they are done remove the baking tray from oven carefully.
