  • Oven


  • 1 small zucchini shredded (about 1 cup) - we used a potato peeler to "shred ours"
  • 8 oz turkey sausage we used the HOT variety
  • 6 slices bread we recommend a good bakery bread
  • 2 cups shredded, reduced-fat sharp cheddar cheese
  • 6 eggs
  • 2 cups low-fat/skim milk
  • 1 tbsp Dijon mustard
  • 1 tsp olive oil


  • Lightly spray an 11x 7โ€ baking dish.
  • Heat the oil in a large, nonstick skillet over medium heat. Add the sausage and cook, stirring often, until the meat is cooked through, about 5 minutes.
  • Line the baking dish with overlapping slices of bread.
  • Sprinkle the zucchini evenly over the bread.
  • Spoon the sausage over the zucchini and sprinkle evenly with the cheese.
  • In a large bowl, stir the eggs with a fork until broken up.
  • Add the mustard then the milk into the bowl with the eggs and stir until well-blended.
  • Pour the egg mixture over the bread mixture in the baking dish.
  • Cover and refrigerate for at least 4 hours or overnight.
  • To bake, preheat the oven to 350 degrees.
  • Uncover the casserole and bake about 45 minutes or until the top is puffy and browned.
  • Allow to cool for 5 - 10 mins before serving.
  • Enjoy!
