Directions1. Prepare the Oven and Filling: Preheat your oven to 350°F / 175°C.
In a large, oven-safe skillet over medium heat, cook the diced bacon until crispy. Use a slotted spoon to transfer the bacon to a plate, leaving about a tablespoon of grease in the skillet.
Add the fresh spinach to the skillet and cook for 1-2 minutes until it has wilted.
Remove from heat.
Mix the Custard: In a large bowl, whisk together the eggs and heavy whipping cream until smooth and airy.
Season generously with salt and pepper.
Assemble and Bake: Stir the cooked bacon, wilted spinach, and about three-quarters of the shredded cheese into the egg mixture.
Pour everything into a greased 9x9 inch baking dish or back into your oven-safe skillet.
Sprinkle the remaining cheese evenly over the top.
Bake to Perfection: Place in the preheated oven and bake for 25-30 minutes, or until the center is set and the top is beautifully golden brown. A knife inserted into the center should come out clean.
Let it rest for 5 minutes before slicing and serving warm.
Sauté diced onions or mushrooms with the bacon for an extra layer of savory depth.
