Cooking Healthy Breakfast Casserole with Spinach and Feta: The Process

Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). This ensures that your casserole bakes evenly and comes out perfectly set.
Step 2: Sauté the Shallots and Spinach
In a skillet over medium heat, spray a little olive oil and add the chopped shallots. Sauté until they become translucent, about 3-4 minutes. Then, add the baby spinach and cook until wilted, stirring occasionally. This step will enhance the flavor of the spinach and shallots, making your casserole even more delicious.
Step 3: Combine the Egg Mixture
In a large mixing bowl, beat the eggs until well combined. Stir in the 2% milk and heavy cream, mixing until smooth. This creamy mixture is what makes the casserole so rich and satisfying.
Step 4: Add the Remaining Ingredients
To the egg mixture, add the crumbled feta cheese, sautéed spinach and shallots, chopped scallions, diced tomatoes, kosher salt, and black pepper. Gently fold the ingredients together until everything is evenly distributed.
Step 5: Prepare the Baking Dish
Spray your baking dish with olive oil spray to prevent sticking. Pour the egg mixture into the dish, spreading it out evenly.
Step 6: Bake the Casserole
Place the baking dish in the preheated oven and bake for about 45-55 minutes, or until the casserole is set in the center and lightly golden on top. To check for doneness, insert a knife into the center; it should come out clean.
Step 7: Cool and Serve
Once baked, remove the casserole from the oven and let it cool for a few minutes. This will make slicing easier. Cut into squares and serve warm, garnished with extra scallions if desired.
