Step-by-Step Instructions
- Preheat the Oven:
- Set your oven to 350 degrees Fahrenheit and let it fully preheat This ensures even baking and the perfect crust
- Prep the Baking Dish:
- Grease an eight by eight inch baking dish with nonstick spray or a light coat of butter so the casserole lifts out easily
- Mix the Vegetables and Cheese:
- Combine the well-drained shredded zucchini onion half of the cheddar cheese the thawed corn and the chopped jalapeño in a large bowl Make sure the mixture is evenly distributed so no pockets are left unmixed
- Add Seasonings and Eggs:
- Sprinkle in the garlic powder cumin salt and black pepper Crack in the eggs and mix everything very thoroughly for homogenous flavor and proper binding
- Stir in the Corn Muffin Mix:
- Gradually sprinkle the corn muffin mix over the wet ingredients Use a gentle folding motion so the cornbread mix coats and combines fully This step keeps the casserole light and prevents overmixing
- Transfer to Baking Dish and Top with Cheese:
- Pour the blended mixture into your prepared baking dish Use a spatula to level the top Scatter the rest of the shredded cheddar cheese evenly for maximum crispiness
- Bake:
- Place the dish on the center rack and bake for fifty to fifty five minutes Watch for a deeply golden brown top and a center that is springy and set
- Cool and Serve:
- Let the casserole cool for about ten minutes before slicing This helps each square hold together Serve warm to enjoy the cheesy crust and tender inside

My favorite ingredient has to be the sharp cheddar cheese I once caught my niece picking all the crispy bits off the top at a family picnic because they are just that good The way the cheese bubbles and browns in the oven is always a crowd pleaser and a nostalgic hit for me
