Step-by-Step Instructions

1. Preheat the Oven

Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with butter or cooking spray to prevent sticking.

2. Prepare the Broccoli

Bring a pot of water to a boil. Blanch the broccoli florets for 2–3 minutes until tender-crisp. Drain thoroughly and set aside. Blanching helps preserve color, texture, and nutrients.

3. Cook the Aromatics and Spinach

In a skillet over medium heat, sauté 1 small diced onion for 3–4 minutes until softened. Add 2 cloves minced garlic and cook for 30 seconds until fragrant. Add 2 cups chopped fresh spinach (or 1 cup thawed, drained frozen spinach) and cook until wilted. Remove from heat.

4. Make the Cheese Mixture

In a large mixing bowl, combine 4 oz softened cream cheese, ½ cup sour cream, ½ cup milk or heavy cream, 1 ½ cups shredded cheddar cheese (reserve ½ cup for topping), 1 cup shredded mozzarella cheese, ½ cup Parmesan cheese (if using), ½ teaspoon salt, ½ teaspoon black pepper, ¼ teaspoon paprika, and a pinch of nutmeg. Stir until smooth and well blended.

5. Combine Everything

Fold in the cooked broccoli and spinach mixture, ensuring all vegetables are evenly coated in the cheese sauce.

6. Assemble the Casserole

Transfer the mixture into the prepared baking dish. Sprinkle the remaining ½ cup cheddar cheese over the top. For added crunch, mix ½ cup breadcrumbs with 2 tablespoons melted butter and sprinkle evenly over the casserole.

7. Bake

Bake uncovered for 25–30 minutes, or until the casserole is bubbly and the top is golden brown.

8. Rest and Serve

Allow the casserole to rest for 5–10 minutes before serving to let it set and make slicing easier. Serve hot as a side dish or vegetarian main.
