Instructions

1. Preheat your oven to 375°F (190°C) and grease a 9×13-inch baking dish lightly with olive oil.

2. Sauté the onion and garlic: In a large skillet over medium heat, heat the olive oil. Add the diced onion and cook until translucent, about 3-4 minutes. Stir in the garlic and cook for an additional minute until fragrant.

3. Steam the vegetables: While the onions are cooking, steam the broccoli and cauliflower until just tender but not mushy, about 4-5 minutes. Drain well.

4. Mix the creamy base: In a large bowl, combine the cream cheese, sour cream, chicken broth, dried thyme, dried oregano, salt, and pepper. Stir until smooth.

5. Combine everything: Add the cooked chicken, sautéed onion and garlic, steamed vegetables, and half of the shredded cheddar and mozzarella cheese to the creamy mixture. Stir well to combine.

6. Assemble the casserole: Pour the mixture into the prepared baking dish and spread evenly. Sprinkle the remaining cheddar and mozzarella on top.

7. Bake: Place the casserole in the oven and bake for 25-30 minutes or until the cheese is melted and bubbly and the top is golden brown.

8. Let it cool: Allow the casserole to cool for about 5 minutes before serving. This helps it to set and makes it easier to cut and serve.
