This broccoli cheddar pasta bake is creamy, hearty, and finished with a crisp golden breadcrumb topping. Made with wholemeal pasta, plenty of broccoli, and a silky cheese sauce, it is a comforting oven-baked dinner that still feels balanced enough for a weeknight meal.
Bring a large pot of salted water to a boil. Cook the wholemeal pasta until just al dente, about 2 minutes less than the package directions. Add the broccoli florets halfway through the pasta cooking time so they become tender but still bright green. Drain well, then toss the pasta and broccoli with the olive oil.
Meanwhile, warm the milk with the bay leaf in a separate saucepan until it is just starting to simmer. Remove from the heat and let it infuse for a few minutes. In another saucepan, melt the butter over medium heat, stir in the flour, and cook for 1 to 2 minutes, stirring constantly, until you have a smooth roux.
Gradually whisk the warm milk into the roux, adding a little at a time to prevent lumps. Cook over low heat for 8 to 10 minutes, stirring often, until the sauce is thick and smooth. Remove the bay leaf, then stir in three-quarters of the grated cheddar, the Dijon mustard, nutmeg, black pepper, and salt to taste. Heat the oven to 180C/160C fan/gas 4.
Transfer the pasta and broccoli to a large baking dish, then pour over the cheese sauce and mix gently to coat. Scatter the remaining cheddar and the breadcrumbs evenly over the top. Bake for 30 to 35 minutes, or until bubbling and deeply golden. Let the bake rest for 5 minutes before serving.
For extra flavor, use mature cheddar or mix in a little Parmesan with the topping. If the sauce seems too thick before baking, loosen it with a small splash of milk. Leftovers keep well in the fridge for up to 3 days and can be reheated in the oven or microwave.
