Instructions:
- Preheat the oven to 375°F (190°C). Lightly grease a baking dish.
- Squeeze as much liquid as possible from the spinach and set aside.
- In a skillet over medium heat, melt the butter. Add the garlic and sauté for about 30 seconds, until fragrant.
- Reduce the heat to low and stir in the heavy cream and cream cheese, whisking until smooth and fully combined.
- Add the Monterey Jack and Parmesan cheeses, stirring until melted and velvety.
- Season the sauce with salt, black pepper, and nutmeg, if using.
- Fold the spinach into the cheese sauce until evenly coated.
- Transfer the mixture to the prepared baking dish and spread evenly.
- Bake uncovered for 25–30 minutes, until hot, bubbly, and lightly golden on top.
- Let rest for 5 minutes before serving.
Variations
- Add a pinch of crushed red pepper for gentle heat.
- Use Gruyère in place of Monterey Jack for a nuttier flavor.
- Stir in sautéed shallots for subtle sweetness.
- Top with a light layer of breadcrumbs for added texture.
Tips
- Draining the spinach thoroughly is essential to avoid a watery casserole.
- Keep the heat low when melting the cheese to maintain a smooth sauce.
- Avoid overbaking to preserve the silky, steakhouse-style texture.
- This casserole can be assembled ahead and baked just before serving.
