Preheat your oven to 190°C/170°C(fan)/375°F/Gas 5.
Put 400 g of Wholewheat fusilli pasta into a pan of boiling water and simmer for 12 minutes.
Put the cooked pasta into a baking dish and add 2 portion of Leftover bolognese.
Mix the bolognese into the pasta.
Top with 80 g of Mature cheddar, 50 g of Mozzarella and 20 g of Parmesan.
Put into the oven for 20 minutes, until heated through.
Notes
Make this a little bit more indulgent by mixing some breadcrumbs with the cheese before crumbling it on top.
If you want the top of this pasta bake to go really crispy, then you can put it under the grill (broiler) for a couple of minutes.
Reserve a little of the pasta water to add to the sauce to make it nice and silky.
Do not overcook the pasta before baking. Slightly undercooked pasta works best, as it will continue cooking in the sauce.
Make sure the Bolognese is saucy enough. Pasta absorbs liquid as it bakes, so a dry sauce will result in a dry pasta bake. Add a splash of water, stock or passata if needed.
Grate the cheddar yourself if you can. Pre-grated cheese often has anti-caking ingredients, which can stop it melting as smoothly.
Let the pasta bake sit for 5 minutes before serving. This helps it hold together a little better and makes it easier to portion.
