COOKBOOK / 1011
Start by melting the butter in a medium skillet over medium heat. Toss in the onion and cook it until it’s nice and soft, about 5 minutes. Sprinkle in the herbes de Provence, salt, and pepper, and cook for another minute. Then stir in the spinach, take the pan off the heat, and set it aside.
Spray a 9x13-inch baking dish with cooking spray. Begin by spreading a third of the bread cubes on the bottom, then add a layer of a third of the spinach mixture, followed by a third of the mozzarella. Repeat this layering two more times until everything’s used up.
In a separate bowl, whisk together the eggs, milk, salt, and pepper until smooth. Pour this mixture evenly over the layered bread and spinach in the dish. Cover it with plastic wrap and pop it in the fridge for at least 8 hours, or up to a full day.
When you’re ready to bake, take the casserole out of the fridge about 30 minutes beforehand to let it come to room temperature. Meanwhile, preheat your oven to 350°F (175°C).
Bake the casserole uncovered for 45 to 55 minutes, until it’s puffed up and golden brown. Once it’s done, let it sit for at least 5 minutes before digging in.
- Use fresh spinach for the best texture, but frozen works well if thoroughly drained.
- Let the casserole rest for a few minutes after baking to make slicing easier.
- For extra flavor, add a pinch of nutmeg or garlic powder to the egg mixture.
This casserole is a great way to start your day with a boost of protein and greens. It’s easy to make ahead, saving you time during busy mornings. Plus, the combination of spinach and mozzarella creates a delicious, comforting flavor everyone will enjoy.
Serve warm with a side of fresh fruit or a light salad to balance the richness. A dollop of salsa or a sprinkle of chopped herbs like parsley or chives can add a fresh touch. This dish also pairs nicely with a cup of coffee or fresh juice.
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven or microwave until warmed through. This casserole can also be frozen for up to 2 months—just thaw overnight in the fridge before reheating.
