- 1/4 cup melted butter
- 2 tablespoons freshly grated Parmesan cheese
- 1/8 teaspoon black pepper
- 1/8 teaspoon garlic powder
- Dash of nutmeg
Instructions
- Preheat the Oven: Start by preheating your oven to 350 degrees Fahrenheit (175 degrees Celsius). This ensures the oven is at the right temperature when you’re ready to bake.
- Prepare the Casserole Dish: Grease a 1 1/2-quart (9-inch square) casserole dish with butter or non-stick spray to prevent sticking, then set it aside.

- Cool and Serve: Remove from the oven and allow the casserole to cool for 5 to 10 minutes. This helps it firm up for easier slicing. Then cut into portions, serve warm, and enjoy your creamy spinach casserole!

- You can substitute the cottage cheese with ricotta if preferred for a different texture.
- For added texture and flavor, consider sprinkling extra Parmesan or breadcrumbs on top before baking.
