Spinach Florentine Breakfast Casserole for Family Mornings

How to Make Spinach Florentine Breakfast Casserole

Step 1: Preheat and Prepare

Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish to prevent sticking and prepare it for the casserole.

Step 2: Sauté Vegetables

Heat olive oil in a large skillet over medium heat. Add the chopped onion and minced garlic, sautéing until they are soft and fragrant, about 3-4 minutes. Toss in the spinach and cook until wilted. Remove from heat.

Step 3: Whisk Eggs and Milk

In a mixing bowl, whisk together eggs, milk, salt, and pepper until well combined. This creates a smooth mixture that will coat your casserole.

Step 4: Combine Ingredients

In the prepared baking dish, layer the sautéed spinach mixture. Sprinkle feta cheese on top, then pour the egg mixture evenly over everything.

Step 5: Bake

Bake for 30-35 minutes or until the eggs are set and the top is golden brown. A knife inserted in the center should come out clean. Remove from the oven and allow it to cool for a few minutes before slicing.

Pro Tips for Making Spinach Florentine Breakfast Casserole

Fresh is Best: Use fresh spinach for optimal flavor and texture; frozen spinach may release excess moisture.
Let it Cool: Allow the casserole to set a bit before slicing; this helps it hold its shape.
Don’t Overmix: Fold the ingredients gently to preserve the airy quality of the egg mixture.
Days Ahead: Prep the casserole the night before, cover it, and refrigerate before baking in the morning.
Test for Doneness: Always check with a knife or toothpick to ensure the center is fully cooked before serving.
