  • 1 tablespoon extra virgin olive oil
  • 1 lb. turkey breakfast sausage, such as Diestel brand or your favorite
  • 1 1/2 cups cubed butternut squash
  • 2-4 tablespoons water
  • 2 cups chopped dinosaur kale
  • 8 large eggs
  • 1/2 cup milk
  • salt and freshly ground black pepper to taste
  • 1/2 cup grated cheddar cheese


  • Preheat the oven to 400 degrees and grease an 8x8" baking dish with cooking spray.
  • Cook the sausage in a large skillet over medium heat, breaking up into small chunks with a wooden spoon until cooked through about 4-5 minutes. Place in a bowl and set aside.
  • Add the butternut squash to the skillet and sauté for 1 minute. Add 2 tablespoons water to the skillet and cook covered over medium heat until tender, about 7-10 minutes, stirring occasionally. Lower the heat if the pan becomes too hot and add more water if it becomes dry.
  • Add the kale to the pan with the butternut squash about halfway through the cooking time in order to wilt slightly.
  • Combine the sausage, butternut squash and kale and pour into an even layer in the bottom of the prepared baking dish.
  • Beat the eggs with the milk in medium bowl, then stir in 1/4 cup of the cheese. Pour the egg mixture evenly over the sausage vegetable mixture, then top with the remaining 1/4 cup of cheese.
  • Bake on the middle rack of the oven for 25-30 minutes or until set. Cool for 5 minutes, then slice, serve and enjoy!


  • This recipe is easily doubled to feed a crowd!
  • Save time by using frozen butternut squash in this recipe! Cook according to package instructions and drain well before adding to this dish.
  • This dish may be customized using any of your favorite vegetables or leftover roasted veggies!  
  • Make this breakfast casserole vegetarian by omitting the sausage and dairy free by omitting the cheese.
