  1. Preheat your oven to 180°C (fan 160°C/gas mark 4).
  2. Cook the macaroni in salted boiling water according to the packet instructions until al dente, then drain and set aside.
  3. In a pan over medium heat, add the olive oil and half of the butter. Once melted, add the sliced red onion, and sauté until soft and translucent, about 5 minutes.
  4. In a separate saucepan, melt the remaining butter. Stir in the flour to make a roux, cooking for 1-2 minutes while stirring continuously.
  5. Gradually whisk in the milk, ensuring no lumps form, and cook until the sauce thickens and coats the back of a spoon, approximately 3 minutes.
  6. Remove the sauce from heat, stir in the cheddar cheese until melted, and season with salt and pepper.
  7. Combine the macaroni and red onions with the cheese sauce, then transfer to an individual ovenproof dish.
  8. Sprinkle the breadcrumbs evenly over the top of the macaroni mixture.
  9. Bake in the preheated oven for 15-20 minutes, until the top is golden brown and crispy.
  10. Remove from the oven and allow to cool slightly before serving.
