Sausage Summer Squash Casserole

I like to mix it up and add a little color by using zucchini for half the amount of squash but use what you have or what you like. The sausage makes it different than other squash casseroles. I could eat it as a main dish casserole!

  • 1 1-pound package breakfast sausage or 1 pound venison sausage (Venison Sausage is always an option at my house)
  • 3 medium yellow or zucchini squash sliced (about 4 cups)
  • 2 large eggs
  • 1/2 cup milk or whipping cream
  • 1 clove garlic minced or 1/4 teaspoon garlic powder
  • 1/2 cup toasted breadcrumbs or 1/3 cup fine dry breadcrumbs (or 1/2 cup shredded Colby Jack for Keto diet)
  • 1/2 cup shredded Parmesan cheese plus 2 tablespoons for topping
  • 1/2 teaspoon salt
  • 1 tablespoon chopped fresh parsley
  • 1 1/2 teaspoons chopped fresh oregano or 1/2 teaspoon dried oregano


  • Preheat oven to 350°. Cook sausage in a large skillet over medium heat, stirring to crumble the sausage as it cooks, until browned; drain and discard drippings.
  • Steam the squash in the microwave by placing it in a large microwave-safe glass bowl; add 2 tablespoon water. Cover with plastic wrap. Microwave at HIGH for 3 minutes. Carefully remove the plastic wrap and drain any water in the bowl.
  • To avoid washing a second bowl, push squash to one side of the bowl. In the other side of the bowl, whisk together eggs; gradually add milk. Toss egg mixture and squash together.
    Add garlic and remaining ingredients and stir together gently.
  • Spoon squash mixture into a greased 11/2-quart casserole dish and sprinkle with 2 tablespoons Parmesan cheese. Bake at 350° for 25 to 30 minutes or until bubbly around the edges.


To make this recipe keto diet friendly, omit the milk and add 1/2 cup whipping cream. Omit the breadcrumbs and add 1/2 cup additional Parmesan cheese or a mixture of Colby and Monterey Jack cheese.
