This recipe uses frozen spinach, and you don’t even have to thaw it. Can be doubled easily.
1 Tbsp. butter
2 10 oz. packages of frozen spinach
2 minced garlic cloves (from the jar)
1/2 Tbsp. flour
1/2 cup milk, cream, or half-n-half
Ground pepper
Pinch of ground nutmeg
In a large nonstick frying pan, melt the butter. Plop the 2 packages of spinach in and gently cook on medium-low until they are thawed/cooked. Add the garlic and cook about a minute more. Sprinkle the flour over the spinach and stir it in well. Cook for about 2 minutes. Add half the milk and cook about 1 minute longer.
In your blender or food processor, add the spinach mixture with the rest of the milk and blend until pureed, this takes about 2 minutes. Push down occasionally with a rubber spatula.
Transfer back to the pan and stir in the spices. Heat till bubbling then pour into a serving bowl.
