How to Make Spinach Florentine Breakfast Casserole
Preheat your oven to 350 °F (175 °C). This step is crucial for ensuring even baking and the perfect texture for your casserole.
Saut chopped onion and spinach in a skillet over medium heat until softened, about 5-7 minutes. The onions should be translucent, and the spinach wilted, releasing its lovely aroma.
Whisk together eggs, milk, salt, and pepper in a large mixing bowl until well combined. This mixture should be smooth and slightly frothy, showcasing its creamy goodness.
Combine the saut ed spinach mixture, cubed bread, and your choice of cheese into the egg mixture. Stir gently to ensure everything is evenly coated with the egg mixture.
Pour the combined mixture into a greased casserole dish, spreading it out evenly. This will allow for even cooking and a beautiful golden top.
Bake for 30-35 minutes or until set and golden on top. The casserole should be firm and slightly puffed up, ready to be sliced and served.
Cool slightly before slicing and serving. Letting it rest for a few minutes enhances the flavors and helps it hold its shape when portioned.
Optional: Garnish with fresh herbs like parsley or chives for a burst of color and flavor.
