Preheat your oven to 190 deg C and use a little of the extra butter to brush around the insides of the ramekins. Dust each ramekin with half of the breadcrumb mixture.
Separate your eggs and proceed to beat the egg whites until they are stiff. Set aside.
Melt the butter on a medium heat and add the flour. Stir well with a wooden spoon and cook the mixture for one minute. Add the milk, mix well and allow it to come to a simmer.
Add the salt and pepper and the egg yolks one at a time, ensuring they are mixed well after each addition. Remove from the heat and add the cheese and basil pesto and mix well.
Fold your egg whites into the mixture using the “cut and fold” technique. Be gentle but not too slow! Pour the cheese souffle mixture into the pre-buttered ramekins and run your finger around the edge of the ramekin.
Sprinkle with some extra grated cheese and the remaining breadcrumbs. Bake for 20-25 mins until golden and serve immediately.
I used four ramekins for this that measured 15cms in diameter and were 6 cms deep
