One of my favorite things about this recipe is that it is a mix and bake kind of recipe. All you need to mix this easy zucchini casserole is one large bowl. No need to break out the heavy kitchen equipment or do tons of dishes. It's super easy to make!

Ingredients in Zucchini Casserole with Bisquick

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 or you can make your own homemade Bisquick. I love baking with Bisquick! You can make Blueberry coffee cake 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

Step 1: Spray a 9x13 inch pan with nonstick cooking spray. In a large bowl, add the shredded zucchini and onions.

Step 2: Add the Bisquick, cheese, eggs, Italian seasonings, salt, and black pepper to the bowl and mix well.

Step 3: Pour the mixture into the prepared baking dish and bake for 40 minutes or until golden brown. Let the casserole cool slightly and then cut into squares.

The zucchini and bisquick are mixed together in a large bowl.

The rest of the ignredients are added to the large bowl.

The zucchini casserole with bisquick is added to a large pan.

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.

Variations

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.

Recipe FAQs

Can I use yellow squash instead of zucchini?

Yes! Make sure to shred all the squash the same size, but you can use your favorite yellow squash, zucchini, or heirloom Summer squash.

Can I use a different sized baking dish?

Yes! You can use a pie dish for a thicker recipe. Then you can cut it into pie slices instead of parmesan zucchini squares.

Can I use frozen zucchini?

Yes! Simply defrost the zucchini and shred it with a food processor or a large knife. Make sure to remove any excess water as the frozen zucchini may have more water than you want in this casserole.
