Ingredients

• 3 medium-sized zucchini
• 2 cups corn kernels (fresh, canned, or frozen)
• 1 medium, finely diced onion
• 2 minced garlic cloves
• 2 eggs
• 0.25 cup all-purpose flour
• 0.5 cup milk
• 1 cup shredded cheddar cheese
• 0.25 cup grated Parmesan cheese
• 2 tablespoons butter
• 1 tablespoon olive oil
• 0.33 cup bread crumbs (optional for topping)
• 0.5 teaspoon smoked paprika
• 1 teaspoon salt
• 0.5 teaspoon black pepper

Directions

Step 1

Preheat your oven to 375°F (190°C). Grease a 9x9-inch baking dish or casserole dish and set it aside.

Step 2

Wash the zucchini, trim the ends, and grate them using a box grater. Place the grated zucchini in a clean kitchen towel and squeeze out as much excess moisture as possible. Set aside.

Step 3

Heat the olive oil and butter in a large skillet over medium heat. Add the diced onion and cook for 3-4 minutes until softened. Add the minced garlic and cook for an additional 1 minute until fragrant.

Step 4

Stir in the corn kernels and grated zucchini. Season with smoked paprika, salt, and pepper. Cook for 5-6 minutes, stirring occasionally, until the mixture is tender and most of the moisture has evaporated. Remove from heat and let it cool slightly.

Step 5

In a large mixing bowl, whisk together the eggs, milk, and flour until smooth. Stir in the cheddar cheese and half of the Parmesan cheese.

Step 6

Add the cooked zucchini and corn mixture to the bowl and mix until well combined.

Step 7

Pour the mixture into the prepared baking dish. Sprinkle the remaining Parmesan cheese over the top. If using bread crumbs, mix them with a drizzle of olive oil and sprinkle over the casserole for a crunchy topping.

Step 8

Bake in the preheated oven for 25-30 minutes, or until the casserole is set and the top is golden brown.

Step 9

Let the casserole cool for 5-10 minutes before serving. Enjoy warm as a side dish or a light main course.
