Begin by preheating your oven to 375°F (190°C). Gather all your ingredients and prepare them as mentioned in your shopping guide.
In a large mixing bowl, add the room temperature cream cheese. Using a spatula or a hand mixer, blend until smooth and creamy.
Incorporate the thawed and drained spinach along with the coarsely chopped artichoke hearts into the cream cheese mixture. Mix well until everything is evenly distributed.
Add the mayonnaise, grated Parmigiano Reggiano, Italian 4-Cheese Shred, minced garlic, garlic salt, chopped fresh basil, and shredded mozzarella. Stir until all ingredients are well combined. Season with salt and pepper to taste.
Pour the mixture into a baking dish and spread it evenly. Use a spatula to smooth the top, ensuring an even layer for baking.
Place the baking dish in the preheated oven and bake for about 25-30 minutes, or until the dip is bubbling and the top is golden brown.
Once it’s baked to perfection, remove it from the oven and let it cool for a few minutes. Serve warm with your favorite dippers, such as tortilla chips, pita bread, or fresh vegetables.
