Spinach & Cheese Strata
This post may contain affiliate links. Read my full disclosure policy.
Layered with spinach, cheese, and bread, and soaked in a savory custard, this make-ahead strata is ideal for entertaining.
A strata is a layered casserole made with bread, eggs, cheese, and sometimes vegetables or meat (strata means layers). Think of it as a savory bread pudding or breakfast casserole. This spinach version is richly flavored with Gruyère, Parmesan, and Dijon mustard. It’s the perfect vegetarian brunch dish to feed a crowd. You do all of the preparation the night before, let the strata rest in the fridge overnight, then pop it in the oven in the morning. As it bakes, it puffs up like a cheese soufflé, making it a real showstopper. The strata does fall a bit as it cools, but it’s still impressive. For an elegant brunch, serve the strata with bacon (for perfectly crispy bacon, learn how to cook bacon in the oven), a strawberry & orange fruit salad, and mimosas.

What You’ll Need To Make Spinach & Cheese Strata
![ingredients for spinach and cheese strata](https://www.onceuponachef.com/images/2015/03/strata-16-760x751.jpg)
Before we get started, a few words about the ingredients. It’s important to use good quality cheese. The recipe calls for a combination of Gruyère and Parmigiano-Reggiano cheese, but since they are both expensive, feel free to substitute other good melting cheeses with bold flavor, like extra-sharp cheddar. The recipe is pretty flexible, so you can play around with different sautéed vegetables depending on what you have on hand. Some cooked sausage or pancetta would be a nice addition; just be sure to reduce the salt in the recipe to a scant teaspoon or the strata will be way too salty.
Be sure to squeeze all of the water out of the spinach. Take your time; it’s important to get it all out or the strata will be watery.
Step-By-Step Instructions
Melt the butter in a skillet over medium heat.

Add the onions and cook, stirring frequently, until soft and translucent, about 5 minutes.

Layer a third of the cubed bread in a buttered 3-quart or 9×13-inch baking dish.

Followed by a third of each cheese.

Repeat layering twice, ending with the cheese.

Make the custard by combining the whisked eggs, half-and-half-Dijon mustard salt, pepper and nutmeg.
![Whisk in a bowl with eggs and seasonings.](https://www.onceuponachef.com/images/2015/03/strata-14-760x545.jpg)
Whisk evenly to combine.

Pour evenly over top of the strata, then cover and refrigerate for at least one hour or overnight.

Bake for about 70 to 80 minutes, until puffed, set and golden all over.

Note: My starting point for this recipe was this popular strata originally published in Gourmet magazine. I increased the spinach; amped up the flavor by adding garlic and increasing the salt; swapped the milk for half-and-half; and reduced the baking temperature from 350°F to 325°F for a creamier texture.

Layered with spinach, cheese, and bread, and soaked in a savory custard, this make-ahead strata is ideal for entertaining.
Ingredients
- 1 pound bag chopped frozen spinach, thawed and squeezed as dry as possible
- 3 tablespoons unsalted butter
- 1 large yellow onion, chopped (about 2 cups)
- 3 garlic cloves, minced
- 12 ounces (¾ pound) Italian sandwich bread, cut into 1-inch cubes (about 11 slices or 8 cups)
- 6 ounces (1½ cups) coarsely grated Gruyère
- 2 ounces (⅔ cup) finely grated Parmigiano-Reggiano
- 9 large eggs
- 2¾ cups half-and-half
- 2 tablespoons Dijon mustard
- 1¾ teaspoons salt
- ¾ teaspoon black pepper
- ¼ teaspoon ground nutmeg
Instructions
- Melt the butter in a large skillet over medium heat. Add the onion and cook, stirring frequently, until soft and translucent, 4 to 5 minutes. Add the garlic and drained spinach and cook 2 minutes more. Set aside.
- Butter a 3-quart or 9x13-inch baking dish. Spread one third of the bread cubes in the dish and top evenly with one third of spinach mixture. (Try to break it up as much as possible so there are no huge clumps of spinach.) Sprinkle with one third of each cheese. Repeat layering twice, ending with cheeses.
- In a large bowl, whisk the eggs. Add the half-and-half, mustard, salt, pepper, and nutmeg and whisk until well combined. Pour the custard mixture evenly over the strata. Cover the strata with plastic wrap and chill for at least 1 hour or overnight.
- Preheat oven to 325°F. Bake the strata, uncovered, until puffed, set and golden brown all over top, 70-80 minutes. Let stand 10 to 15 minutes before serving. It will settle a bit as it cools.
- Note: The cook time is based on the strata going immediately from the fridge to the oven. If it sits out at room temperature before baking, the cook time will be about 10 minutes less.

Is this considered vegetarian?
Yep!
Jen, I have tried many of your recipes and am in LOVE with them all! I have a question on this one. I bought too much dry “stuffing bread.” Can I use it in this recipe?
Also please tell me your cookbook will be out in time for Christmas!
Hi Mel, so glad you like the recipes! If you’re referring to bread here, that should work, but I wouldn’t recommend packaged stuffing cubes. And my cookbook won’t be released until the Spring of 2018 (so I hope you’re patient :)!
Perfect brunch or dinner fare! Loved this! Thanks!!!
Hi Jenn, is there any substitute for 1/2 and 1/2? by the way I love your recipes!!! thank you for making meal time so easy and tasty! Giselle
Hi Giselle, Glad to hear you like the recipes. I think you could get away with using milk here.
I made this for breakfast yesterday and it was amazing! I cut the recipe in half, using an 8×8 baking dish, and baked it for about an hour and fifteen minutes. Perfect and delicious. I did use both cheeses in the recipe, which were pricey, so I’m glad it was a success! I also served the strawberry/orange fruit salad with it. Thank you – I will visit often and will be making more recipes from this site, for sure.
Excellent dish – we used sharp cheddar with the Parmesan reggiano, as suggested
Is it possible to freeze, and at what temp to bake frozen?
Hi Maureen, I haven’t frozen this before, but other readers have successfully. When you’re ready to serve it, I would defrost it in the fridge overnight. Before putting it in the oven cover it tightly with foil, then reheat it at 325 degrees until hot in the center, probably about 35 – 40 minutes. Hope everyone enjoys!
Made this for Fathers Day breakfast. Was a hit with the family.
what is half &half
From Australia Adelaide
Half and half is equal parts whole milk and light cream. Enjoy!
OnceUponAChef is my go-to recipe site, by far! Quick question: if I have leftover strata, will it keep/warm up well?
Yes Kate, this reheats very nicely!
