I would expect the broccoli to cook along with the potatoes. No need to parcook.
As for the bacon should I pre cook that?
Ok so I want to make a casserole with potatoes brocoli and bacon among other little ingredients. But I was wondering if I should parcook the brocoli and bacon before putting it in the oven
That sounds like a great idea.I would precook everything and tie it all together with a nice cheese sauce, just bake it till it bubbles and browns!
