Grate zucchini, and place in a colander. Sprinkle the zucchini with ½ teaspoon salt. Allow to drain for 30 minutes. After 30 minutes squeeze water out of the zucchini.
Preheat the oven to 350 degrees. Spray a 7x10 pan with non-stick cooking spray.
Place zucchini on paper towels and squeeze to remove additional water.
Add the Jiffy Corn Mix, shredded zucchini, onion, eggs, seasoning, and 1 ½ cups shredded cheese to a large bowl. Mix to combine.
Spoon into the prepared casserole dish. Top with remaining shredded cheese.
Bake uncovered in preheated oven for 30-40 minutes or until a toothpick inserted into the center comes out cleanly.
Cool for 10 minutes. Slice and enjoy!
Notes
**Note the three cups of shredded zucchini is measured before the water is drained.I used a 7x10 inch staub pan. If you'd prefer use a 9x9 pan. If you do, please note the baking time.
