Tips for Making the Best Zucchini Casserole

Below, find a collection of tips and tricks to make the best zucchini casserole bake on the planet.

• Use the freshest zucchini you can find. The fresher the zucchini the better. Grab a haul from your local farmer’s market if you can!
• Don’t over-salt the batter. Keep in mind that the cheese will add a bit of salt, so resist going overboard.
• Grate the carrots and zucchini large. You’ll want the casserole bake to have a bit of bite, so grate the zucchini and carrots on the largest slots of the cheese grater. If you go any smaller, they will turn to pulp and alter the texture.
• Don’t forget to oil the pan. This casserole back is prone to sticking, so make sure to coat the pan with a generous amount of oil or cooking spray.
