Ingredients


– 4 medium zucchini, sliced
– 1 medium onion, chopped
– 2 cups shredded cheddar cheese
– 1 cup grated Parmesan cheese
– 1 cup breadcrumbs
– 3 large eggs
– 1 cup sour cream
– 1 teaspoon garlic powder
– 1 teaspoon onion powder
– Salt and pepper to taste
– 2 tablespoons olive oil
– Fresh parsley for garnish (optional)

Step-by-Step Instructions


Making Cheesy Zucchini Casserole is straightforward when you follow these easy steps:
1. Preheat the Oven: Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking dish.
2. Prepare the Zucchini: Slice the zucchini into thin, even rounds. Place them in a colander and sprinkle with salt to draw out moisture. Let them sit for about 10 minutes, then pat dry with paper towels.
3. Sauté the Onion: In a skillet, heat the olive oil over medium heat. Add the chopped onion and sauté until soft and translucent, about 5 minutes. Remove from heat.
4. Mix the Egg Mixture: In a large bowl, whisk together the eggs and sour cream until well combined. Stir in garlic powder, onion powder, salt, pepper, and half of the cheddar cheese.
5. Combine Ingredients: Add the sautéed onions and sliced zucchini into the egg mixture, folding gently to combine.
6. Layer the Casserole: Pour half of the zucchini mixture into the prepared baking dish. Sprinkle half of the Parmesan cheese on top. Then, layer the remaining zucchini mixture on top, followed by the rest of the Parmesan.
7. Top with Breadcrumbs and Cheese: Finally, sprinkle the remaining cheddar cheese and breadcrumbs evenly across the top. Drizzle with a little olive oil for extra crispness.
8. Bake: Place the casserole in the preheated oven and bake for 30-35 minutes or until the top is golden brown and bubbly.
9. Cool and Serve: Remove from the oven and allow to cool for 10-15 minutes. This helps it set and makes it easier to cut into portions.
Now that your Cheesy Zucchini Casserole is ready, it’s time to savor the deliciousness!

Serving your Cheesy Zucchini Casserole might be just as important as making it! To make the most of this delightful dish, consider the following tips:

2. Garnish: Sprinkle some fresh parsley or basil on top to enhance the visual appeal and add a fresh contrast to the cheese.
3. Accompaniments: Pair with a crisp salad or roasted vegetables to balance the richness of the casserole. Add a light vinaigrette to the salad to complement the flavors.
4. Portion Control: Serve generous portions, but consider smaller servings to encourage guests to come back for seconds without feeling overindulged.
