Cheese and broccoli are a match made in heaven, tell me otherwise! It is tale as old as time and this recipe is exactly that. For this I used some charred broccoli leftovers I had kicking around and I think it was the perfect addition. Typically broccoli leftovers are kinda smelly and aren’t the easiest to use up but I think this takes it to the next level. I also made fresh herby homemade breadcrumbs which added an extra delicious element.

When making this dish I do suggest charring your broccoli first. I know it seems like a lot of time but it really does give it that extra element of flavour, and the best part is you’d be using the same cast iron pan anyways. The oven will already be on and needed so it’s just a little bit of extra time for that extra result. Additionally while the broccoli is crisping in the oven it’s a great time to make your mornay sauce to make sure it’s all silky and delicious.

I can show you the world! And that world is The Best Cheesy Broccoli Au Gratin! Let’s get down to business! Too many Disney puns I know.
