Heat the butter in a large skillet over medium heat.
Add minced garlic and shallots to the skillet. Saute until they are translucent (~2 minutes).
Turn the pan heat to medium low. Then, add the heavy cream, cream cheese, parmesan cheese, and black pepper to the pan. Use a silicone spatula to incorporate the ingredients. You want the cream cheese fully melted.
Add the spinach to the pan and mix it with the sauce. You want to cook this until it is slightly wilted.
Taste the Creamed Spinach and decide if you'd like to add a pinch of salt (~1/8 tsp). Serve immediately.
