Ingredients to Gather
- Zucchini. You will need 4 cups of shredded zucchini. Shred the zucchini with a food processor or a cheese grater. Depending on the size of the zucchini, that will be 3 medium or 2 large zucchini.
- Eggs. The large eggs keep the zucchini bake together and it also helps with the rise of this zucchini casserole recipe.
- Bisquick Baking Mix. You can find Bisquick in the grocery store in the pancake or breakfast aisle. I love baking with Bisquick! You can make Blueberry coffee cake, Bisquick cinnamon rolls, breakfast casserole with bisquick, turkey pot pie with Bisquick, or banana pancakes with bisquick. Make sure that your bisquick is not expired or the recipe will not be as light and fluffy as it should be.
- Olive Oil. This adds the added fat to the recipe that makes it savory and delicious. You can use vegetable oil if you do not have olive oil.
- Cheese. Both parmesan cheese and cheddar cheese will be used in this recipe.

Step By Step Instructions
Tips and Tricks
- Make sure your Bisquick is fresh and not expired.
- You can shred your own parmesan cheese or cheddar cheese but you can also buy the already shredded cheese in the grocery store to make your life easier.
- The zucchini does not need to be drained before you add it to the mixture. The excess liquid from the zucchini will help keep the zucchini bake from being dry.
- Serve this zucchini casserole with some chopped fresh herbs. It's a perfect side dish to Instant Pot Chicken Drumsticks or Instant Pot Chicken Thighs.
- Slice the zucchini instead of shredding it. If you prefer larger pieces of zucchini, thinly slice the zucchini and then add the zucchini slices to the large mixing bowl.
- Change the cheese! You can use pecorino romano cheese, mozzarella cheese, colby jack cheese, or your favorite type of cheese.
- Add protein! To make this a main dish, add ground beef, cooked ground sausage, or cooked ground chicken to the mixture.
- Change the spices! You can add garlic powder, a chopped fresh garlic clove, crushed red pepper flakes, or fresh parsley and fresh basil.
- Make it gluten-free! Bisquick makes a gluten free version, so use that instead of regular Bisquick.
Yes! Make sure to shred all the squash the same size, but you can use your favorite yellow squash, zucchini, or heirloom Summer squash.
Yes! You can use a pie dish for a thicker recipe. Then you can cut it into pie slices instead of parmesan zucchini squares.
Keep leftovers in an airtight container in the refrigerator for up to 4 days. You can also freeze this zucchini bake once it is baked. To defrost, place the pan in the refrigerator and then reheat it in the oven for 20-30 minutes.
