What Kind of Spinach Should I Use?

For the Spinach Florentine Breakfast Casserole, fresh spinach is the best choice due to its vibrant flavor and tender texture when cooked. Fresh spinach wilts beautifully, allowing it to integrate seamlessly with the other ingredients, while also providing a nutritious boost without becoming too soggy. If you only have frozen spinach on hand, you can certainly use it as a substitute; just make sure to thaw and thoroughly drain it before adding it to the casserole to avoid excess moisture that could make the dish watery.

Ingredients for the Spinach Florentine Breakfast Casserole

Each ingredient in this dish plays an essential role in flavor and texture. Here’s what you’ll need:

4 cups Fresh Spinach (Chopped): Adds vibrant color and a nutritious boost.
1 cup Onion (Diced): Provides sweetness and depth of flavor.
1 cup Bell Pepper (Diced): Contributes a crunchy texture and mild sweetness.
6 large Eggs: Acts as the binding agent, creating a fluffy base.
1 cup Milk (Whole or 2%): Helps to create creaminess and richness in the casserole.
1 cup Shredded Cheese (Mozzarella or Cheddar): Melts beautifully, adding savory flavor and creaminess.
1 teaspoon Salt: Enhances all the flavors, bringing balance to the dish.
1/2 teaspoon Black Pepper: Adds a subtle warmth and depth of flavor.
1/2 teaspoon Garlic Powder: Infuses the casserole with aromatic goodness.
2 tablespoons Olive Oil (For sautéing): Essential for cooking the vegetables, enhancing their flavors.
4 slices Bread (Cubed, optional): Offers a hearty texture that soaks up the flavors beautifully.

How To Make the Spinach Florentine Breakfast Casserole

Sauté the Vegetables

Preheat your oven to 350°F (175°C). In a skillet, heat 2 tablespoons of olive oil over medium heat. Add 1 cup of diced onion and 1 cup of diced bell pepper, sautéing until softened, which should take about 5 minutes. Once they’re fragrant and tender, stir in 4 cups of chopped fresh spinach and cook until wilted, approximately 3 minutes. Remove the skillet from the heat and set the mixture aside.

Whisk the Egg Mixture

In a mixing bowl, crack open 6 large eggs and add 1 cup of milk. Sprinkle in 1 teaspoon of salt, 1/2 teaspoon of black pepper, and 1/2 teaspoon of garlic powder. Whisk the ingredients together vigorously until well combined and slightly frothy, ensuring everything is evenly mixed for a smooth consistency.

Assemble the Casserole

Grease a 9×13 inch baking dish to prevent sticking. If you’re using bread, layer the cubed bread at the bottom of the dish first. Next, evenly distribute the sautéed vegetable mixture over the bread. Pour the egg mixture carefully over everything to make sure it’s well incorporated.

Top with Cheese

Sprinkle 1 cup of shredded cheese — either mozzarella or cheddar — generously on top of the casserole. This layer will create a deliciously gooey topping that melts beautifully while baking.

Bake until Golden

Place your assembled casserole in the preheated oven and bake for about 30-35 minutes. You’ll know it’s done when the eggs are set in the center and the top is golden brown and bubbly. Keep an eye on it towards the end to avoid over-baking.

Cool and Serve

Once baked, remove the casserole from the oven and allow it to cool for a few minutes before slicing. This resting time helps it firm up slightly, making it easier to serve neatly. Enjoy your hearty Spinach Florentine Breakfast Casserole!

How to Serve and Store Spinach Florentine Breakfast Casserole

To store leftovers, keep them in an airtight container in the refrigerator for up to 3 days. When it’s time to reheat, add a splash of milk and warm it slowly in a skillet over low heat to prevent the vegetables from becoming soggy. While this casserole can be frozen, be aware that the texture may change slightly upon reheating, so it’s best enjoyed fresh when possible.

Can I use almond milk instead of regular milk? Yes, you can substitute almond milk for regular milk in this recipe. Just be aware that it might slightly alter the creaminess and flavor, but it will still work well.

Is this breakfast casserole gluten-free? To make this dish gluten-free, simply omit the bread or use gluten-free bread. The rest of the ingredients are naturally gluten-free, making it easy to adapt for those with dietary restrictions.

Can I prepare this casserole ahead of time? Absolutely! You can assemble the casserole a day in advance and store it covered in the refrigerator. Just bake it just before serving for a fresh, delicious breakfast.

How do I know when the casserole is done baking? The casserole is done when the eggs are set and the top has turned a golden brown color. You can also insert a knife in the center; if it comes out clean, it’s ready to serve.

Can I add other vegetables to this recipe? Yes, feel free to customize your casserole by adding other vegetables like mushrooms, cherry tomatoes, or zucchini. Just ensure they are sautéed until softened before mixing them into the egg mixture for optimal flavor.
