  • dry measuring cups
  • measuring spoons
  • large skillet

Ingredients

  • 1 small yellow onion, diced (about 1 cup)
  • 1 small red bell pepper, diced (about 1 cup)
  • 1 (5-ounce) package baby spinach
  • 1 (16-ounce) package breakfast sausage

  • 1 cup shredded Parmesan cheese
  • 1 teaspoon kosher salt
  • ½ teaspoon freshly ground black pepper
  • ½ teaspoon crushed red pepper flakes

Instructions

  • Preheat the oven to 350°F. Coat a 13- x 9-inch baking pan with cooking spray.
  • Brown the sausage in a large skillet over medium-high heat for 6 minutes or until the sausage crumbles and is no longer pink. Remove the sausage from the skillet using a slotted spoon, reserving the drippings in the skillet.
  • Add the onion and bell pepper to the skillet and cook until softened, about 5 minutes. Stir in the spinach and cook for 1 more minute or until wilted. Set aside.
  • Process the cottage cheese in a food processor until very smooth. Add the eggs, salt, black pepper, and crushed red pepper and pulse until combined.
  • Arrange the sausage and vegetables in the bottom of the prepared baking dish along with the cheeses. Pour the egg mixture over the top.
  • Bake for 40 minutes or until the casserole is set. Let stand 5 minutes before cutting into wedges to serve.
