Ingredients for Spinach Florentine Breakfast Casserole

Getting the ingredients right is key to making this Spinach Florentine Breakfast Casserole shine! Here’s what you’ll need:

  • 4 cups fresh spinach, chopped: I always recommend using fresh spinach for the best flavor and texture. Make sure to chop it roughly – it’ll wilt down beautifully in the oven.
  • 1 cup milk: Any kind of milk works here, whether it’s whole, skim, or even a non-dairy alternative. It adds moisture and richness to the eggs.
  • 6 large eggs: These are the backbone of your casserole, providing that fluffy, custardy texture that makes every bite so satisfying.
  • 1 cup shredded mozzarella cheese: Use freshly shredded mozzarella if you can! It melts beautifully and gives that gooey, cheesy goodness we all love.
  • 1 cup diced bread: I like to use a hearty bread like sourdough or whole grain, which gives the casserole a nice bite. Make sure to dice it into bite-sized pieces.
  • 1/2 cup diced onion: A sweet onion works nicely here, adding a subtle flavor that compliments the spinach.
  • 1 teaspoon garlic powder: This is one of my secret weapons for flavor! It enhances the savory notes without the need for fresh garlic.
  • Salt and pepper to taste: Don’t forget to season! A pinch of salt and a twist of pepper will elevate the flavors beautifully.

With these ingredients on hand, you’re all set to whip up a delicious and nutritious breakfast that everyone will love!

How to Prepare Spinach Florentine Breakfast Casserole

Now that we have our ingredients ready, let’s dive into the fun part – preparing this delightful Spinach Florentine Breakfast Casserole! Follow these simple steps, and you’ll have a delicious breakfast on the table in no time.

Step-by-Step Instructions

  1. Preheat the oven: First things first, preheat your oven to 350°F (175°C). This ensures your casserole cooks evenly and reaches that perfect golden-brown top.
  2. Whisk together the eggs and milk: In a large mixing bowl, crack the six eggs and pour in the cup of milk. Whisk them together until well combined – you want a nice, frothy mixture that will help create that fluffy texture.
  3. Add the veggies and spices: Now, toss in the chopped spinach, diced onion, garlic powder, salt, and pepper. Give everything a good stir until the spinach is well coated and everything is mixed evenly.
  4. Incorporate the bread and cheese: Next, fold in the diced bread and half of the shredded mozzarella cheese. Be gentle here; you don’t want to break up the bread too much. This is where the casserole gets its hearty base!
  5. Transfer to the baking dish: Grease a baking dish (I prefer a 9×13 inch dish) and pour the mixture in, spreading it out evenly. This step is crucial for ensuring every bite is packed with flavor.
  6. Top with cheese: Finally, sprinkle the remaining mozzarella cheese on top. This will create a delicious, melty layer that everyone will love.
  7. Bake it up: Pop your casserole into the preheated oven and bake for 30-35 minutes. You’ll know it’s done when it’s set in the middle and the top is beautifully golden brown. Keep an eye on it, as oven times can vary!

Let it cool slightly before serving, and enjoy the smiles from your family or guests as they dig into this scrumptious breakfast treat!

Variations of Spinach Florentine Breakfast Casserole

If you’re feeling adventurous, there are so many fun ways to mix up your Spinach Florentine Breakfast Casserole! Here are a few of my favorite variations:

  • Swap the Spinach: Kale is a fantastic substitute if you want a different leafy green. It adds a nice texture and flavor, plus it’s super nutritious!
  • Add Proteins: For a heartier dish, consider mixing in cooked sausage, diced ham, or crispy bacon. They add a savory punch that pairs beautifully with the eggs.
  • Change the Cheese: Experiment with different cheeses like feta for a tangy kick or sharp cheddar for a more robust flavor. You could even mix a couple of your favorites!
  • Seasoning Enhancements: Try adding spices like smoked paprika or freshly cracked red pepper flakes for a bit of heat, or throw in some fresh herbs like dill or thyme for a fragrant twist.
  • Vegetable Medley: Feel free to toss in other veggies like bell peppers, mushrooms, or zucchini. They not only add color but also boost the nutrition and flavor!

With these variations, you can keep your breakfast casserole exciting and tailored to your taste preferences. Happy cooking!
