Ingredients Breakdown

Makes approximately 8 servings.

Vegetables & Cheese

• 3 1/2 cups well-drained, shredded zucchini
• 1 diced white onion
• 1 cup thawed frozen corn
• 1 diced jalapeño (deseeded for milder flavor)
• 16 ounces shredded cheddar cheese (half mixed in, half reserved for topping)

Seasonings

• 1 teaspoon garlic powder
• 1 teaspoon cumin
• 1 teaspoon salt
• 1/2 teaspoon black pepper

Other

• 2 eggs
• 8.5-ounce box of corn muffin mix

Tools & Equipment Needed

• Large mixing bowl
• Box grater or food processor (if shredding zucchini yourself)
• Measuring cups and spoons
• 9×13-inch casserole dish
• Spatula or wooden spoon
• Colander (for draining zucchini)

Step-by-Step Instructions

1. Prepare the Zucchini

Grate fresh zucchini and place it in a colander or clean kitchen towel. Press or squeeze out as much moisture as possible—this is key to keeping your casserole from becoming watery.

2. Mix the Base

In a large bowl, combine the shredded and drained zucchini, diced onion, thawed corn, diced jalapeño, and half the shredded cheddar cheese.

3. Add Seasonings and Eggs

Sprinkle in the garlic powder, cumin, salt, and black pepper. Crack in the eggs and stir well to combine all ingredients evenly.

4. Incorporate Corn Muffin Mix

Add the entire box of corn muffin mix to the bowl and gently fold everything together until just combined. The batter will be thick but moist.

5. Assemble the Casserole

Transfer the mixture into a greased 9×13-inch casserole dish. Spread evenly, then sprinkle the reserved cheddar cheese over the top for a cheesy crust.

6. Bake

Preheat your oven to 350°F (175°C) and bake uncovered for 40-45 minutes, until the casserole is golden on top and set in the center. A toothpick inserted should come out mostly clean.

7. Rest and Serve

Allow the casserole to cool for 10 minutes before slicing. This helps it set and makes serving easier.

Tips & Variations

• Drain zucchini well: Moisture is the enemy of a firm casserole, so don’t skip this step.
• Spice level: Keep the seeds in the jalapeño for more heat or swap for a milder pepper if preferred.
• Add fresh herbs: Chopped cilantro or parsley brightens the flavors beautifully.
• Make it vegan: Use a vegan cornbread mix, egg substitute like flax eggs, and dairy-free cheese.
• Add protein: Stir in cooked, crumbled sausage or shredded chicken for a heartier dish.
• Use fresh corn: Swap frozen corn for fresh, cut off the cob during summer months.

Flavor Profile & Pairings

The casserole has a wonderful balance of creamy, cheesy richness and bright veggie freshness. The cumin and garlic provide a warm, earthy undertone while the jalapeño adds a subtle heat that wakes up the palate. The cornbread base adds a satisfying crumbly texture and mild sweetness that pairs beautifully with the savory ingredients.

Pair it with:

• A crisp green salad with lemon vinaigrette for freshness.
• Grilled or roasted meats for a complete meal.
• Black beans or a spicy salsa for a Southwestern twist.

Drink Pairings:

• A chilled Riesling or Pinot Grigio complements the mild heat and cheese.
• For a non-alcoholic choice, iced tea with a splash of lime or sparkling water with cucumber.
