How to Make Spinach Florentine Breakfast Casserole

Follow these simple steps to prepare this delicious Spinach Florentine Breakfast Casserole:

Step 1: Prepare the Spinach
Place the thawed spinach on a clean kitchen towel and squeeze it firmly to remove as much liquid as possible. Set the well-drained spinach aside for later use.

Step 2: Sauté the Vegetables
Heat olive oil in a large skillet over medium-high heat. Add the chopped onion and cook until it’s translucent, about 5 minutes. Stir in the garlic, cooking until fragrant, roughly 30 seconds more. Next, introduce the spinach and sauté until it looks slightly dried out, around 2 minutes. Set this mixture aside to cool slightly.

Step 3: Mix the Cheese and Spinach
In a medium bowl, reserve a quarter cup of the spinach mixture. To the remaining spinach, add the mascarpone cheese, half a cup of Parmesan, ½ teaspoon salt, and ½ teaspoon pepper. Mix well and set aside.

Step 4: Whisk the Egg Mixture
In a large bowl, whisk together the eggs, half-and-half, crushed red pepper, reserved spinach mixture, and remaining Parmesan, salt, and pepper until fully combined. The blending of ingredients should be thorough, ensuring each bite is as flavorful as the last.

Step 5: Assemble the Casserole
Lightly grease a 13×9-inch baking dish. Arrange the bottom halves of the English muffins in the dish, creating three rows of two. Spread the creamy spinach-mascarpone mixture evenly over the muffins, then cover with the top halves of the English muffins. Pour the egg mixture over the casserole, pressing down gently on the muffins to submerge them. Finish by sprinkling the remaining Parmesan on top.

Step 6: Refrigerate and Bake
Cover the dish with foil and refrigerate for at least 1 hour, or up to 12 hours, to let the flavors meld beautifully. When you’re ready, preheat the oven to 350°F. Uncover and bake until the casserole is just set and the tops of the muffins are golden brown, about 45 minutes. Allow it to cool for 10 minutes before serving for the perfect slice.

Serve this Spinach Florentine Breakfast Casserole warm, perhaps with a sprinkle of fresh herbs or a dollop of sour cream on the side. Each slice will be a delightful burst of flavors and memories, bringing a smile to your face and a warmth to your heart. Enjoy this splendid dish any time of day, because who says you can’t have breakfast for dinner?

Perfecting Spinach Florentine Breakfast Casserole Cooking Process

Start by prepping your spinach to remove excess moisture. Sauté the onions and garlic first for aroma and flavor, then combine them with the spinach before mixing with mascarpone. Finally, assemble with the egg mixture over the muffin base.

Add Your Touch to Spinach Florentine Breakfast Casserole

Feel free to swap the mascarpone cheese for ricotta or cream cheese for a different flavor profile. You can also toss in other veggies like bell peppers or mushrooms, or add herbs such as basil or dill for freshness.

Storing & Reheating Spinach Florentine Breakfast Casserole

Store leftovers in an airtight container in the fridge for up to three days. To reheat, simply warm in the oven at 350°F until heated through, which helps maintain its fluffy texture.

Making sure to squeeze the spinach well prevents a soggy casserole, while whisking the egg mixture thoroughly ensures even cooking. For extra flavor, consider adding a pinch of nutmeg to the egg mixture, making it an elegant touch that elevates the dish.

Sometimes, I’ll make this Spinach Florentine Breakfast Casserole for Sunday brunch with friends, and the compliments pour in like it’s a Michelin-star meal!
