One of the best things about this great recipe is the variety of ingredients that can be added to it or substituted.

Let’s Dive Into It!

  • Stuffing Mix – Stove Top stuffing mix is very convenient and the entire box is used in this easy recipe. Classic seasoned stuffing like Pepperidge Farm can be substituted especially if you are planning a big meal and doubling the recipe!
  • Cream of Chicken Soup – Cream of mushroom soup is a favorite way to make this casserole a more vegan friendly dish.
  • Onion – Whatever onion you have on hand will work. Red onion, yellow, or sweet all will taste great. 
  • Carrots – Carrots add great texture and flavor. Adding chopped red bell pepper adds a wonder flavor and a burst of color to this casserole.
  • Sour Cream – If can substitute regular sour cream for light sour cream or plain Greek yogurt.
  • Shredded Cheese – (optional) I love to mix in just a little bit of shredded Parmesan cheese to the topping. You can use your favorite shredded cheese.

Make It A Main Dish

  • A great way to make this casserole a one dish meal is by adding a couple of cups of rotisserie chicken or cooked ground beef to the zucchini mixture before baking it.
  • Adding leftover turkey to the casserole is a delicious way to make it a main dish for the whole family to enjoy during the holidays.
