FAQ's
You'll know the casserole is done when a toothpick inserted into the center comes out cleanly.
Yes, you can swap out the zucchini for yellow summer squash.
The casserole should be baked uncovered for the best results. This will give you a little crispy texture on the outside.

Deb's tips
- Make sure you squeeze as much liquid out of the zucchini as possible before adding it to the casserole. This will help ensure your cornbread casserole has a nice texture and isn't a soggy mess.
- If you don't have Montreal Steak Seasoning, use whichever seasoning blend is your favorite.
- Be sure to spray your casserole dish well with nonstick cooking spray, or grease it with butter or shortening.
Variations
- You can use a mixture of zucchini and yellow squash to change up this yummy dish.
- Add some diced bell peppers or a can of cream-style corn if you want more vegetables. The cream-style corn would add a touch of sweetness.
- Garlic powder and black pepper can be added to the casserole to add more flavor.
- Instead of cheddar cheese, you can use pepper jack cheese, Mexican blend cheese, or even Monterey jack cheese.
Storage
Refrigerate - Leftovers can be wrapped in plastic wrap or stored in an airtight container and refrigerated for up to 3 days.
Freezer - This casserole does not freeze well due to the cornbread mix.
Reheat - Reheat leftovers in the microwave on 30-second intervals until heated through.

Linda
Just had this recipe tonight. I did add an extra egg. Very good. I have a couple ideas for future meals. Bake it in a loaf pan. Cool completely. Slice and fry till crispy on the outside. Also as a one dish meal; fry up ground beef or sausage - add to mix, pour into casserole dish and bake as directed. Thanks for the inspiration.
