Instructions:
- Preheat the oven to 375°F (190°C). Lightly grease a small baking dish.
- In a large skillet over medium heat, melt the butter. Add the diced onion and cook for 3 to 4 minutes, until softened.
- Stir in the garlic and cook for about 30 seconds, just until fragrant.
- Add the spinach and cook until fully wilted. Drain off excess liquid thoroughly, then chop the spinach finely.
- Return the spinach to the skillet and stir in the cream cheese and heavy cream until smooth and creamy.
- Add the Parmesan cheese, mozzarella cheese, nutmeg, salt, and black pepper. Mix until fully combined.
- Spread the spinach mixture evenly into the prepared baking dish.
- In a small bowl, combine the panko breadcrumbs, melted butter, and Parmesan cheese.
- Sprinkle the topping evenly over the spinach mixture.
- Bake uncovered for 20 to 25 minutes, until bubbly and golden on top.
- For extra crispiness, broil for 1 to 2 minutes at the end, watching closely.
Variations
- Add a pinch of cayenne pepper or red pepper flakes for subtle heat.
- Stir in a splash of white wine when cooking the spinach for added depth.
- Substitute Gruyère for mozzarella for a more pronounced, nutty flavor.
- Add finely chopped artichoke hearts for a Rockefeller-inspired twist.
Tips
- Drain the spinach extremely well to prevent a watery casserole.
- Finely chopping the spinach ensures a smooth, steakhouse-style texture.
- This dish can be assembled ahead of time and baked just before serving.
- Serve hot alongside steak, prime rib, or roasted meats for the full steakhouse experience.
