Ingredients

• 4 medium zucchinis, thinly sliced
• 1 red bell pepper, diced
• 1 yellow bell pepper, diced
• 1 small onion, finely chopped
• 2 cloves garlic, minced
• 1 cup shredded cheddar cheese
• 1/2 cup grated Parmesan cheese
• 1/2 cup sour cream
• 1/2 cup mayonnaise
• 1 teaspoon dried oregano
• 1 teaspoon dried basil
• Salt and pepper to taste
• 1/2 cup breadcrumbs
• 2 tablespoons olive oil

Step-by-Step Instructions

1. Preheat the Oven

Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with olive oil or cooking spray.

2. Sauté the Vegetables

In a large skillet, heat the olive oil over medium heat. Add the chopped onion and garlic, and sauté until fragrant, about 2 minutes. Add the diced bell peppers and cook for another 3-4 minutes until they begin to soften.

3. Prepare the Zucchini

Add the thinly sliced zucchini to the skillet and cook for 5 minutes, stirring occasionally, until the zucchini is slightly tender but still firm. Season with salt, pepper, dried oregano, and dried basil.

4. Mix the Cheese Sauce

In a separate bowl, combine the sour cream, mayonnaise, shredded cheddar cheese, and grated Parmesan cheese. Mix well until smooth and creamy.

5. Assemble the Casserole

Spread the sautéed vegetables evenly in the prepared baking dish. Pour the cheese sauce over the vegetables and spread it out evenly. Sprinkle the breadcrumbs on top for a crispy finish.

6. Bake to Perfection

Bake in the preheated oven for 25-30 minutes, or until the top is golden brown and the casserole is bubbly. Let it cool for a few minutes before serving.

Expert Tips

• Use Fresh Vegetables: For the best flavor, use freshly picked zucchini and bell peppers from your garden or local farmers’ market.

• Make It Ahead: This casserole can be assembled ahead of time and refrigerated until ready to bake. Just add a few extra minutes to the baking time if it’s cold.
• Customize with Herbs: Feel free to experiment with fresh herbs like thyme or rosemary for added depth of flavor.
