Preheat your oven with the broiler option.
In a medium-sized saucepan on medium heat, add olive oil. When the oil is shimmering and hot add in minced garlic. Cook until fragrant, about 1 min.
Add in the chopped artichoke hearts, cook for 1-2 min until warmed through.
Add in thawed spinach and salt. Cook until most of the water has evaporated, about 5 minutes.
Add in cream cheese and black pepper, and mix until all the cream cheese has melted.
Remove from heat, add in parmesan and sour cream and mix. Taste to adjust seasoning.
Place the mixture into an oven-safe dish, top with freshly shredded mozzarella. Place in the oven for 5 minutes or until cheese is melted and bubbling. Remove from oven and serve with chips or pieces of toasted bread. Enjoy!
