Prepare the Spinach

1. Melt 2 tablespoons of butter in a large skillet over medium-high heat.
2. Add the sliced green onions and sauté for about 1 minute until fragrant.
3. Add the spinach a handful at a time, stirring to wilt after each addition. Continue until all spinach is wilted.
4. Transfer the spinach mixture to a colander and press firmly to remove excess liquid.

Make the Cream Sauce

1. Return the skillet to medium heat and melt the remaining 2 tablespoons of butter.
2. Add minced garlic and sauté for about 1 minute, stirring frequently to prevent burning.
3. Stir in the heavy cream and ground nutmeg. Cook, stirring often, until the mixture thickens and reduces, about 5 minutes.

Combine and Finish

1. Return the drained spinach to the skillet and stir into the cream sauce. Cook for an additional 3 minutes to blend the flavors.
2. Remove from heat and stir in the cheese blend until melted and smooth.
3. Season with salt and pepper to taste. Serve warm.
