Cook your macaroni according to the package instructions - when it’s cooked, drain the pasta and coat it in 0.5tbsp oil to prevent the pasta from sticking or from absorbing too much of the sauce when baking.
225 g macaroni
Meanwhile, in your skillet or casserole pan, melt the remaining butter. Add the flour, mixing it into the butter to form a dough. Cook off the flour for 2-3 minutes.
6 tbsp butter, 6 tbsp plain flour
Add 0.5 cup of the milk, whisking constantly until you get a smooth paste, then slowly whisk in the remaining milk until you have a smooth sauce with no lumps.
3.5 cups milk
Remove the pan from the heat, then stir in the seasonings and ¾ of the cheese.
1 tsp smoked paprika, 1 tsp garlic powder, 1 tsp dried oregano, 1 tsp dried thyme, 0.5 tsp nutmeg, 75 g grated cheddar cheese, 37.5 g gloucester cheese, 37.5 g monterey jack cheese
Add the pasta to the sauce, mixing it until fully combined.
Top the macaroni cheese with the breadcrumbs and remaining cheese, and bake in the oven for 15 minutes until the top is golden brown - you could also pop it under the grill with a sprinkle more cheese in the last 5 minutes to get an extra golden, bubbly topping.
25 g grated cheddar cheese, 12.5 g gloucester cheese, 12.5 g monterey jack cheese
Store any leftovers in an airtight container in the fridge for up to 4-5 days. Reheat in the microwave or in an ovensafe dish in the oven - you might need to add a splash of water or milk to loosen to sauce if it’s thickened
