Method
- Preheat oven to 375°F (190°C). Lightly grease four oven-safe ramekins (or one larger baking dish).
- Heat olive oil in a large skillet over medium heat. Add onion and cook until softened, about 5 minutes.
- Add garlic and cook for another minute, until fragrant.
- Add spinach to the skillet and cook until wilted, about 3-5 minutes. Season with salt, pepper, and nutmeg (if using). Drain any excess liquid from the spinach. Set aside.
- In a medium saucepan, melt butter over medium heat. Whisk in flour and cook for 1-2 minutes, stirring constantly, to create a roux.
- Gradually whisk in milk, making sure to smooth out any lumps. Continue whisking until the sauce thickens, about 5-7 minutes.
- Remove from heat and stir in salt, pepper, and nutmeg. Add Gruyère cheese and stir until melted and smooth. Taste and adjust seasonings as needed.
- Divide the wilted spinach evenly among the ramekins.
- Pour the Mornay sauce over the spinach in each ramekin.
- Using the back of a spoon, create a small well in the center of the sauce in each ramekin. Gently crack an egg into each well.
- If using, drizzle 1 tablespoon of heavy cream over each egg.
- Bake for 12-18 minutes, or until the egg whites are set but the yolks are still runny (or cooked to your liking).
- Remove from the oven and let cool for a minute or two before serving.
- Garnish with fresh chives and red pepper flakes (if desired).
- Serve immediately with toasted bread or English muffins for dipping.
Notes
For runny eggs, bake a few minutes longer. To avoid rubbery eggs, don't overbake. Squeeze excess water from the spinach to prevent a watery sauce. If Mornay sauce is lumpy, use an immersion blender or strain through a sieve. Add cooked ham, bacon, or sausage for extra protein. Spice it up with cayenne pepper. Try different cheeses like fontina or mozzarella. Prep spinach and Mornay sauce ahead of time and refrigerate for up to 2 days.
