Cheesy broccoli bake (broccoli casserole) is the perfect, easy make-ahead side dish. Perfect for everything from a simple weeknight dinner to a Thanksgiving feast.
I’m a big fan of covering vegetables in creamy cheese sauce and baking until golden brown. But something tells me that pretty much no person on Earth would be against that. Right? I mean, even the most hatiest (totally a word) vegetable haters will love this glorious cheesy broccoli bake (or broccoli casserole as it is also called).
Not only is it absolutely delicious but it’s also SO easy to make. The cheese sauce is a one-pot wonder and comes together in minutes (check out the video below) and is layered with steamed broccoli and mozzarella before baking. You could blanch or roast the broccoli as well, you just want to make sure it’s par-cooked before layering with the cheese sauce.
I love serving this cheesy broccoli casserole with roast chicken or pan-seared pork chops for an easy weeknight dinner but if you’re thinking about side dishes for Thanksgiving or Christmas, this one is a total winner. Also, well done you planner you! It also helps that you can assemble it up to two days ahead and keep it covered in the fridge until you’re ready to bake it. Winning, all around!
How to make broccoli casserole?
Steam, roast or blanch fresh broccoli florets until just tender. Test this by sticking a sharp knife into the stem. If it inserts easily, the broccoli is cooked. Cooking the broccoli before covering in cheese sauce will allow the casserole to bake quickly. To make the cheese sauce, melt butter in a saucepan then whisk in flour to make a roux. Pour in milk while whisking until the sauce is smooth. Add spices of your choice and mix in. Smoked paprika, nutmeg, dried oregano, mustard powder and chilli flakes all work very well in cheese sauce. Turn down the heat and allow to simmer until the sauce has thickened and is cooked through. It should have no floury taste. Remove from the heat and mix in the grated cheddar cheese. Grease a baking dish with melted butter then add the par-cooked broccoli. Pour the cheese sauce over the broccoli and top with shredded mozzarella cheese. Place in a hot oven and allow to bake for 20-25 minutes until golden brown and bubbling. Remove from the oven, allow to rest for 5 minutes then serve.

What cheese goes with broccoli and cheese?
Using a strong cheese like mature or aged cheddar, Parmesan, Gruyere is best for broccoli and cheese. The flavor of the cheese needs to be able to stand up to the flavor of the broccoli. Adding a good melting cheese like mozzarella, Raclette or Fontina will add lush creaminess.

I really would have liked to make this but when I’m in the kitchen cooking, I don’t want to read a blog. I want to read a recipe.
There are no measurements, quantities and it’s all just text so when I’ve got lots going on in the kitchen, I want steps to follow so I can cook multiple things at the same time and not have to stop and re-read paragraphs of blog then figure out measurements.
If you scroll down there’s a recipe box with all the quantities and method in steps.
I’m going to try this. It looks really good and I love broccoli anyhow.
Hope you love it Jean!
The perfect side dish. Made it with roasted pork and potatoes and added a salad for my vegetarian friend. Smiles all around!
Sounds perfect! 🙂
My family loved this. We eat a lot of broccoli and I’m out of ideas but this was really good.
So happy I could provide some new inspiration.
