Over medium high heat, melt the butter. Once melted and the pan is hot, add the spinach and cook until wilted. Toss in the tomatoes and cook until sweating.
Gently pour in the heavy cream and add the parmesean cheese. Whisk to combine.
Gently add cracked eggs into the milk mixture. Top with crumbled bacon and remaining parmesean cheese.
Bake for 8-10 minutes, until eggs are at the consistency you prefer. Remove from heat and serve.
