Cheesy Broccoli Casserole

Friday, October 26, 2018
Broccoli Cauliflower Casserole baked in a cheesy homemade sauce and topped with a buttery panko bread crumbs is a favorite casserole side dish recipe. It has no condensed or cream of something soup and is made with easy to find pantry staple ingredients that you might already have on hand. I don't par boil my veggies before assembling because I don't like mushy vegetables and find that the broccoli and cauliflower comes out cooked to perfection if it's baked in the cheesy sauce.

Cheesy Broccoli Casserole is a favorite vegetable casserole recipe for Thanksgiving, Christmas, and holiday gatherings since it can be assembled ahead of time and baked before serving but deliciousness enough to be a regular on the dinner table.

Cheesy Broccoli Casserole recipe with crunchy panko topping is a favorite casserole for the holidays from Serena Bakes Simply From Scratch.

Cheesy Broccoli Casserole is a favorite side in our house, even though technically this is a Broccoli and Cauliflower Casserole, because I only had 1 head of broccoli. I had to use the cauliflower in its place, but the kids always know it by Cheesy Broccoli Casserole so we are sticking with the familiar name for sanity's sake. Otherwise they will grill me for the next 30 minutes on what exactly it is I am making and planning to feed them.

And by them I mean mainly Mas because he's taken a sudden interest in trying his best to be a picky eater at the ripe old age of 10, but so far I am still winning the battle. He forgets he has 2 older siblings, and I've already been through this. Like when Lorna was little and told me she didn't like mushrooms. So I would put shiitake mushrooms in soup, and tell her they were calamari. She gobbled them up without a complaint!
After a few months I told her the truth of my evil ways, and she loved mushrooms ever since. Even LJ who has all these rules around when he will and won't eat cheese devours this one with pleasure. I think he categorizes this in the Baked Macaroni and Cheese with Panko family so all is good!

The kids always put in a request for this side since the broccoli, or broccoli and cauliflower dependent on what's happening in the fridge is covered in glorious velvety cheese sauce, and a crunchy panko topping. And by velvety cheese sauce I'm not talking about that plastic like Velveeta stuff. We are talking homemade deliciousness.

It's all about Sharp Cheddar, and in this case Sharp White Cheddar, because it's what I had in the fridge, but Medium Cheddars A-OK in my book too. Or even better Gruyere, the cheesy goodness possibilities are endless.

I love this dish for the holidays because I can assemble the Cheesy Broccoli Casserole ahead of time omitting the panko topping, until it's ready to be baked.

I strongly suggest you make this one sometime soon! Let me know if you do.

  1. Serena, it has been so long since I have cooked a broccoli casserole. My little man likes his broccoli plain, but I might get him to try your casserole. My hubby will love it!

  5. I love how easy this was to make, it's a fantastic recipe. My only change was to add some seasoning to the mixture before I put the cheese in. But this is seriously wonderful!

  7. 1 1/2 cups Chicken Stock is listed twice. Is this correct?

  8. Are there any spices? Didn’t see any so I added some that appealed to me. I also added some sautéed mushrooms.

  9. Can this be made up to 24 hours in advance (and leave out panko topping)? Also raw broccoli and cauliflower, all other recipes I see indicate cooked or slightly cooked. Does it make it crunchy if not boiled for a minute or two beforehand? thanks

    1. Hi! Yes you could make it ahead and add the panko right before baking. I find adding them raw leaves the veggies firm but not crunchy and avoids mushy veggies. Thanks, Serena

  10. Made this tonight from a printed copy of this recipe. Please note that the print version doesn’t include adding the onion and garlic to the butter before adding the flour. May want to edit that part. Thanks.
