This looks so delicious...

Recipe from TheKitchn.

Yields 2 cups

Ingredients
2 (10 ounce) bags fresh spinach
2 tablespoons butter
1/2 medium onion, chopped
2 cloves garlic, minced
2 tablespoons flour
1 cup heavy cream
1 cup milk (2% or whole)
1/4 cup dry white wine (optional)
1/2 cup grated Parmesan Cheese
1/2 teaspoon Worcestershire Sauce
1/2 cup chopped artichoke hearts
1/4 cup sour cream
1/2 grated white cheddar cheese
Kosher salt and pepper, to taste

Directions
In a large stockpot of boiling water, add spinach and cook until bright green, approximately one minute. Drain and squeeze out excess water. Coarsely chop and set aside.
In a straight-sided saute pan or sauce pot, melt butter over medium heat. Sauté onions until soft and tender, then add garlic and cook for another minute. Add flour and cook for another minute, until no flour is visible. Pour in cream, milk, wine and, stirring constantly, cook until thickened. Remove from heat and stir in Parmesan and Worcestershire sauce. Season with salt and pepper.
Meanwhile, mix together spinach, artichokes, and sour cream. Pour warm cream mixture over spinach, add white cheddar, and combine thoroughly. Season again, to taste.
Serve warm with tortilla chips, pitas, or crudité and sides of salsa and sour cream. To reheat, warm in a saucepan over medium low heat.
