How to Make Spinach Florentine Breakfast Casserole
- Prep the Spinach: Begin by placing the spinach on a clean kitchen towel and squeezing firmly over the sink to remove as much liquid as possible. This ensures a great texture in your casserole! Set aside.
- Sauté the Aromatics: Heat the olive oil in a large skillet over medium-high heat. Add the chopped onion and cook for about 5 minutes until translucent. Stir in minced garlic and cook for another 30 seconds until fragrant.
- Cook the Spinach Mixture: Add the drained spinach to the skillet, cooking for about 2 minutes while breaking it up with a wooden spoon until it looks dried out. Allow it to cool slightly for about 5 minutes before moving to the next step.
- Mix the Cheese Filling: Reserve 1/4 cup of the spinach mixture and transfer the remainder to a medium bowl. Add mascarpone cheese, 1/2 cup of grated Parmesan, 1/2 teaspoon salt, and 1/2 teaspoon black pepper. Stir until well combined and set aside.
- Whisk the Egg Mixture: In a large bowl, whisk together the eggs, half-and-half, crushed red pepper, reserved spinach mixture, 1/4 cup Parmesan, and the remaining salt and pepper until fully combined.
- Assemble the Casserole: Lightly grease a 13×9-inch baking dish. Arrange the bottom halves of the English muffins in three rows of two in the dish. Spread the spinach-mascarpone mixture over the muffins, then cover with the top halves of the English muffins. Pour the egg mixture over the casserole, pressing down gently to submerge the muffins. Top with the remaining 1/4 cup Parmesan.
- Chill and Bake: Cover the dish with foil and refrigerate for at least 1 hour (or up to 12 hours). Preheat the oven to 350°F, uncover the casserole, and bake until just set and tops are golden brown, about 45 minutes. Let it cool for 10 minutes before serving.

Spinach Florentine Breakfast Casserole Recipe FAQs
What type of spinach should I use for the casserole?
I recommend using frozen chopped spinach as it’s both convenient and nutrient-packed. Just make sure to thaw and drain it thoroughly to avoid a watery casserole. If you’re feeling adventurous, you can use fresh spinach too—just sauté it until it wilts before adding it to the dish.
