Breakfast casserole

Kick-start your day with our delicious breakfast casserole made with eggs, veggie sausages, peppers, red onion and cheese – it's a great way to feed a crowd


  • 250g chestnut mushrooms, sliced
  • 1½ tbsp vegetable oil, plus extra for the tin (optional)
  • 6 veggie sausages, sliced into bite-sized pieces
  • 1 large red onion, finely sliced
  • 2 red peppers, deseeded and sliced
  • 8 eggs
  • 250ml whole milk
  • 125g cheddar, grated
  • 10g chives, finely sliced


  1. Heat the oven to 200C/180C fan/gas 6. Fry the mushrooms in a large non-stick frying pan over a medium-high heat until the liquid has released and evaporated, about 8-10 mins. Add ½ tbsp oil and fry until golden, about 2 mins. Remove from the pan and tip into a large bowl.
  2. Wipe out the pan to remove any excess liquid, then return to a medium heat. Add the remaining oil and fry the sausages until golden all over. Remove using a slotted spoon and add to the bowl with the mushrooms. Fry the onions and peppers, stirring occasionally for 8-10 mins until soft but not browned. Tip into the bowl with the sausages and mushrooms, and mix everything together to combine. Season well. Tip the sausage and veg mixture into a baking dish (around 35 x 25cm) or roasting tin. If you’re using a tin, you may need to oil it to prevent the casserole from sticking.
  3. Combine the eggs, milk, cheddar and chives in a large jug, season well, then pour this over the ingredients in the dish or tin. Bake for 25-30 mins until golden and set. Leave to cool slightly before cutting into squares.
