Ingredients

Instructions

  • Preheat the oven to 340 degrees F / 170 C.
  • Melt the butter in a medium pot over a medium-low heat.
  • When melted sprinkle in the flour and stir to combine, cook on low heat for 2 minutes.
  • Add ¼ cup of milk at a time, stirring in between each addition to ensure there’s no lumps.
  • When all the milk has been added continue to cook for another 2 minutes, stirring continuously.
  • Add the cheddar cheese, nutmeg, salt and pepper. Stir for 3-4 minutes until well combined and cheese is fully melted, adjust seasoning to taste. Remove from the heat.
  • In a large oven dish add the vegetables in an even layer, cover with the cheese sauce, stirring gently to ensure the vegetables are coated in the sauce.
  • Sprinkle the panko crumbs and parmesan cheese over top of the vegetables.
  • Bake in the oven for 30-35 minutes. The topping should be a lovely golden color and the vegetables should be tender.
  • If the vegetables need to be cooked a little longer cover the baking dish with foil and continue to cook for a further 5-10 minutes until completely cooked through, do not over cook.
  • Serve immediately or store leftovers in the fridge for up to 4 days.
