Tomato, Mushroom and Gruyere Breakfast Casserole

This hearty breakfast meal, full of healthy fresh tomatoes and mushrooms, gets lots of its terrific flavour and texture from the English muffins that line the bottom of the dish. Ideally, prepare the night before and bake in the morning.

Method

  • Arrange the roll halves in the bottom of a greased baking dish, cutting them to fit if necessary. Set aside.
  • Heat the tablespoon olive oil on medium heat. Add the onion, then the tomatoes and mushrooms. Season with sea salt and freshly ground black pepper to taste. Cook for about 10 minutes, until the mushrooms are tender and the tomato sauce thickens, stirring occasionally.
  • Spoon the tomato and mushroom sauce over the muffins and set aside to allow to cool.
  • In a large bowl, whisk together the eggs, milk, garlic powder and onion powder. Season with a pinch of salt and some black pepper. Pour evenly over tomato mixture, then sprinkle this with basil. Cover and chill overnight.
  • The next morning, leave the dish aside at room temperature for about 1 hour if possible and preheat your oven to 180 degrees C.
  • Sprinkle casserole with cheese and bake, uncovered, until puffed, cooked through and cheese is golden brown, about 30 minutes.
  • Serve hot with a green salad and fresh bread.
