1-First, preheat your oven to 375°F (190°C) and gather all ingredients to ensure a smooth cooking process. Thoroughly thaw and drain the frozen chopped spinach to prevent excess moisture that can affect texture. Chop artichoke hearts into small, manageable pieces to evenly distribute flavor.

2-In a heavy, oven-safe skillet or pan, melt the butter over medium-low heat. Add the green onions and cook, stirring frequently, until they are softened and fragrant, about 5 minutes. Remove from heat and stir in the cream cheese and sour cream until the mixture is smooth, then add the artichokes, spinach, parmesan cheese, half of the mozzarella cheese, garlic, and hot sauce if using.

3-Stir to combine, then season with salt and pepper to taste. Spread the mixture evenly in the skillet and top with the remaining mozzarella cheese. Bake uncovered for 20 minutes or until bubbling and the cheese is melted. For a golden brown top, broil for 2 minutes, watching carefully to avoid burning, then let it cool slightly before serving warm with chips or toast.
