Ingredients

For the skillet bake

8 large eggs
3 tablespoons heavy whipping cream
2 tablespoons unsalted butter plus more to grease the skillet if needed
4 cups fresh baby spinach loosely packed
1 cup shredded cheese cheddar, mozzarella, or a mix, divided
1/4 teaspoon garlic powder
1/4 teaspoon onion powder
1/8 teaspoon crushed red pepper flakes optional, for heat
1/8 teaspoon ground nutmeg optional
1/2 teaspoon fine sea salt divided, or to taste
1/4 teaspoon black pepper or to taste

Optional add-ins and toppings

4 slices cooked bacon chopped, optional
1/2 cup sliced mushrooms sautéed and drained, optional
1/4 cup crumbled feta cheese optional
2 tablespoons chopped fresh herbs such as parsley or chives, optional

Instructions

Preheat the oven to 375°F and place an oven-safe skillet on the stove over medium heat.
Add the butter to the skillet and let it melt, swirling to coat the bottom and sides lightly.
Add the fresh spinach to the skillet with a small pinch of salt and cook, stirring often, until wilted and most of the moisture has evaporated.
Spread the cooked spinach evenly over the bottom of the skillet and remove the skillet from the heat while you prepare the egg mixture.
In a mixing bowl, whisk the eggs and heavy cream together until very well combined and slightly frothy for a light, even texture.
Whisk in the garlic powder, onion powder, red pepper flakes, nutmeg, remaining salt, and black pepper until the seasonings are evenly dispersed.
Stir in about three fourths of the shredded cheese, along with any cooked bacon, sautéed mushrooms, or feta if using, keeping the remaining cheese for the topping.
Pour the egg and cheese mixture evenly over the sautéed spinach in the skillet, gently nudging the spinach so it is dispersed throughout the eggs.
Sprinkle the remaining shredded cheese evenly over the top to create a cheesy crust as it bakes.
Transfer the skillet to the preheated oven and bake until the edges are set, the center has a slight jiggle, and the top is golden, about 15 to 20 minutes depending on skillet size and oven.
Remove the skillet from the oven and let the bake rest for 5 minutes to finish setting and make slicing easier.
Top with chopped fresh herbs if desired, slice into wedges, and serve warm with keto-friendly sides such as avocado, salad, or sausage.
For meal prep, let the leftover bake cool completely, slice into portions, and store in airtight containers in the refrigerator for up to 4 days.
Reheat individual portions gently in a skillet over medium low heat or in the microwave until warmed through, taking care not to overcook the eggs.

Notes

To keep this skillet bake from turning watery, always sauté the spinach until most of its moisture has cooked off before adding the eggs. Use heavy whipping cream instead of milk for the lowest carb count and the richest, most custardy texture. For extra flavor, season in layers by lightly salting the spinach as it cooks and then tasting and adjusting the egg mixture before baking. Avoid overbaking; remove the skillet when the center still has a slight jiggle, as the eggs will continue to set while resting. This recipe is highly flexible, so feel free to adjust the cheeses and optional add-ins to match your preferences while staying within keto guidelines.
