Simple Steps For Spinach Florentine Breakfast Casserole

Step 1: Warm Up the Oven

Fire up your oven to a cozy 375F (190C). Grab a 9×13-inch baking dish and give it a generous coating of cooking spray or butter to prevent sticking.

Step 2: Sauté the Flavor Boosters

• Diced onions
• Minced garlic

Heat these until they become fragrant and golden. If using fresh spinach, add it now and cook until it wilts and becomes tender. Once done, set this magical mixture aside.

Step 3: Create the Creamy Egg Base

• Eggs
• Milk
• Heavy cream
• Salt
• Pepper
• A pinch of nutmeg for that extra warmth

Step 4: Build Your Casserole Layers

• Spread bread cubes across the bottom of the baking dish
• Scatter the spinach and onion mixture over the bread
• Sprinkle generously with
• Mozzarella cheese
• Parmesan cheese
• Pour the egg mixture evenly across the top
• Gently press down on the bread to help it soak up all the delicious liquid

Step 5: Optional Color Burst

If you want to make your casserole pop, dot the surface with halved cherry tomatoes.

Step 6: Bake to Perfection

Slide the dish into the preheated oven. Bake for 30-35 minutes until the top turns a beautiful golden brown. Check doneness by inserting a knife – it should come out clean.

Step 7: Rest and Serve

Let your casserole rest for 5-10 minutes. This helps it set and makes cutting easier. Sprinkle with fresh herbs like parsley or basil for a final touch of freshness. Serve while warm and watch everyone’s eyes light up!

Tips To Help With Spinach Florentine Breakfast Casserole

• Spinach Selection Matters: Choose fresh, vibrant spinach leaves for the most nutrients and best flavor. Frozen spinach works too, but squeeze out excess moisture before adding to prevent a watery casserole.
• Bread Base Trick: Use day-old or slightly stale bread cubes to help them absorb the egg mixture more effectively. Brioche or challah bread will create a richer, more luxurious texture.
• Customize Cheese Blend: Experiment with different cheese combinations like gruyère, fontina, or goat cheese to add depth and complexity to the dish. Mix cheeses for a more interesting flavor profile.
• Make-Ahead Magic: Assemble the casserole the night before and refrigerate. Let it sit at room temperature for 30 minutes before baking to ensure even cooking and prevent cracking.
• Dietary Adaptations: Swap regular milk with almond or oat milk for a dairy-free version. Use gluten-free bread for a celiac-friendly option. Add crispy bacon or ham for extra protein if desired.
