Preheat oven to 350 degrees F (175 degrees C).
Grease the cooking dishes with Butter (1/2 tablespoon).
Cook Bacon (8 slice) as desired, set aside.
In a skillet over medium heat, melt Butter (1/2 tablespoon). Sauté Fresh Baby Spinach (6 ounce) until just wilted. Distribute evenly among oven-safe cooking/serving dishes.
Add 4 tbsp Heavy Cream (16 tablespoon) to each dish.
Create a small well in the spinach, and crack two Egg (8) into each container. Season with Kosher Salt (to taste) and Freshly Ground Black Pepper (to taste).
Cook in a water bath: Place cooking/serving dishes on a baking pan and place it in the oven. Carefully add hot water to the pan so it goes 1/3 to 1/2 way up the sides of the cooking dishes.
Bake for 10-15 minutes or until the eggs are done to your liking. Remove from oven, crumble bacon on top. Serve immediately.
