Ingredients
  

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

Method
 

Instructions
  1. Preheat your oven to 375°F (190°C). Grease a 9x13-inch baking dish with olive oil or cooking spray.
  2. 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. 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. In a separate bowl, combine the sour cream, mayonnaise, shredded cheddar cheese, and grated Parmesan cheese. Mix well until smooth and creamy.
  5. 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 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.

Notes

Use fresh vegetables for the best flavor. For a crunchy topping, mix breadcrumbs with melted butter before sprinkling. The casserole can be assembled ahead of time and refrigerated until ready to bake. Customize with herbs like thyme or rosemary for added depth of flavor.
