Detailed Instructions
1. Initial Preparation
Preheat your oven to 200°C (390°F). Position the rack in the middle of the oven to ensure even heat distribution. Lightly grease a 9×13 inch (23×33 cm) baking dish with olive oil or cooking spray.
2. Vegetable Preparation
Cut the zucchini into uniform 1/4-inch (6mm) rounds. Slice the carrots diagonally into thin medallions. Cut the bell pepper into 1-inch (2.5cm) chunks. Peel and dice the sweet potato into 1/2-inch (1.2cm) cubes to ensure proper cooking. Dice or grate the tomatoes, and finely mince the garlic.
3. Seasoning and Assembly
In a large mixing bowl, combine the zucchini, carrots, bell pepper, and sweet potato. Drizzle with olive oil, then sprinkle with oregano, paprika, salt, and black pepper. Toss thoroughly to ensure even coating of all vegetables. Transfer this mixture to the prepared baking dish, arranging in an even layer.
4. Layering
Distribute the prepared tomatoes evenly over the vegetable mixture. Sprinkle the minced garlic across the surface. Pour the cooking cream or Greek yogurt over the vegetables in a steady stream, using a spatula to spread it evenly. Finally, distribute the grated cheese uniformly over the top.
5. Baking Process
Place the casserole in the preheated oven and bake for 35-40 minutes. The casserole is ready when the vegetables are tender when pierced with a fork, and the cheese has melted and developed a golden-brown crust.
