Cheesy Broccoli Pasta Bake
To make a broccoli pasta bake, cook pasta and broccoli together until just done, toss with a creamy cheese sauce made from a butter-and-flour roux, milk, and grated cheese, then top with more cheese and bake at 190 °C until bubbling and golden. Adding the cheese to the sauce off the heat keeps it smooth, and the broccoli sneaks vegetables into a dish kids love. It assembles ahead and bakes when you need it.
A cheesy broccoli pasta bake is comfort food that happens to sneak vegetables past everyone at the table — pasta and broccoli bound in a creamy cheese sauce, baked until golden and bubbling. It’s the kind of dinner kids ask for and parents feel good about, and it assembles ahead for the nights you have zero time.
Keep the sauce smooth
The heart of it is a good cheese sauce. Make a roux (butter + flour, cooked a minute), whisk in warm milk until silky, then melt the cheese in off the heat — boiling it once the cheese is in turns it grainy. Grate from a block, not a bag, and use sharp cheddar for flavour plus a melty cheese like mozzarella for stretch.
Cook the broccoli right in
Toss the broccoli into the pasta water for the last few minutes — one pot, and it comes out just tender, ready to fold into the sauce. Small florets distribute better and disappear into the cheesy comfort.
Make it ahead
Assemble the whole thing, refrigerate up to a day (or freeze), and bake when you need it — a genuine weeknight lifesaver.
Make it yours
- Protein: cooked chicken, ham, bacon, sausage, or a tin of tuna.
- More veg: peas, cauliflower, or spinach alongside the broccoli.
- Crunchy top: buttered breadcrumbs or extra cheese.
- Grown-up: a little mustard, cayenne, or blue cheese in the sauce.
Bake until it’s golden and bubbling at the edges, then let it settle a few minutes so it scoops cleanly. It’s cozy, cheesy, veg-smuggling comfort the whole family will finish.

Frequently asked questions
How do I keep the cheese sauce smooth?
Make a roux (butter and flour cooked a minute), whisk in warm milk until smooth and thickened, then stir the grated cheese in OFF the heat. Boiling the sauce after the cheese goes in makes it grainy or split. Grate the cheese yourself from a block — pre-shredded is coated in starch that melts less smoothly. Sharp cheddar for flavour plus a melty cheese like mozzarella gives you both taste and stretch.
Can I assemble it ahead of time?
Yes — it's a great make-ahead. Assemble the whole bake in the dish, cover, and refrigerate for up to a day, then bake when needed (add a few minutes since it's going in cold). You can also freeze it unbaked. Make the sauce a touch looser than you'd like if preparing ahead, because the pasta keeps absorbing sauce as it sits.
How do I add protein to make it a full meal?
Stir in cooked chicken, ham, crispy bacon, or browned sausage before baking, or a tin of tuna for a tuna-pasta-bake spin. Cooked lentils or white beans work for a meatless protein boost. The cheesy base carries all of them. Add the extra protein when you fold the pasta into the sauce so it's evenly distributed through the bake.
