Spinach Florentine Casserole Made Simple

• Warm Up the Oven

Crank your oven to a toasty 375F and give a 9×13-inch baking dish a quick butter massage.

Dance some olive oil in a skillet, then toss in chopped onions and garlic. Let them sizzle and sing for 2-3 minutes until they’re fragrant and happy.

• Welcome the Spinach

Tumble fresh spinach into the skillet, letting it wilt and soften. Remove from heat and set aside.

• Craft the Egg Symphony

In a big mixing bowl, whip eggs with milk, cream, a pinch of salt, pepper, and a whisper of nutmeg until they’re smooth and dreamy.

Spread bread cubes across the baking dish like a cozy blanket.

Rain down mozzarella and Parmesan cheese.

Pour the egg mixture evenly, gently pressing bread to soak up all the goodness.

If you’re feeling fancy, sprinkle cherry tomato halves on top.

• Bake to Perfection

Slide into the oven for 30-35 minutes until golden and set. A knife should come out clean when poked.

Let it rest 5-10 minutes, then slice. Shower with fresh herbs if you’re feeling extra. Enjoy warm and proud!

Instructions

1. Preparation: Preheat oven to 375F (190C) and generously grease a 9×13-inch baking dish with cooking spray or butter.
2. Sauté Base: In a large skillet, warm olive oil over medium heat and cook onions and garlic until translucent, then add spinach and cook until wilted and moisture evaporates.
3. Egg Mixture: Whisk eggs with milk, heavy cream, salt, black pepper, and nutmeg until combined and slightly frothy.
4. Layer Foundation: Spread bread cubes evenly across the baking dish, top with the spinach-onion mixture, and sprinkle mozzarella and Parmesan cheese generously.
5. Liquid Integration: Pour egg mixture over the casserole, gently pressing bread to absorb liquid, and optionally decorate with halved cherry tomatoes.
6. Baking Process: Bake for 30-35 minutes until the center sets and the top turns golden brown.
7. Finishing Touch: Allow casserole to rest for 5-10 minutes, garnish with fresh parsley or basil, slice, and serve warm.

Notes

• Prevent Soggy Bottom: Ensure spinach is thoroughly drained to avoid excess moisture that could make bread cubes soggy and compromise casserole texture.
• Cheese Melting Technique: Grate cheese freshly and mix varieties for optimal melting and rich, complex flavor profile across the dish.
• Egg Mixture Consistency: Whisk eggs and dairy thoroughly until slightly frothy, which helps create a light, airy texture and ensures even distribution of ingredients.
• Temperature Control: Let casserole rest after baking to allow proteins to set, making cutting and serving cleaner and preventing potential burning of mouth from hot filling.
