Instructions
Step 1 – Preheat the Oven
Preheat your oven to 350°F (175°C).
Lightly grease an 8×8-inch baking dish with cooking spray or butter.
Step 2 – Prepare the Zucchini
Shred the zucchini and squeeze out as much liquid as possible using a clean kitchen towel or cheesecloth.
This step helps prevent a watery casserole.

- Shredded zucchini

- Half of the cheddar cheese
- Thawed corn
- Diced jalapeño
- Eggs
- Garlic powder
- Ground cumin
- Salt
- Black pepper
Mix until evenly combined.
Step 4 – Add the Corn Muffin Mix
Gradually stir the corn muffin mix into the vegetable mixture until fully incorporated.
Do not overmix.
Step 5 – Assemble
Spread the mixture evenly into the prepared baking dish.
Top with the remaining shredded cheddar cheese.
Step 6 – Bake
Bake for 50–55 minutes, or until:
- The center is fully set
- The cheese is melted and golden
- A toothpick inserted in the center comes out clean
Step 7 – Rest & Serve
Allow the casserole to rest for 5–10 minutes before slicing.
Serve warm.
