Holiday Breakfast Casserole with Alpine Cheddar: the perfect breakfast or brunch casserole when company’s coming. It’s the most delicious breakfast casserole I’ve ever had.

~leans forward to whisper~

“There are a lot of crappy breakfast casserole recipes floating around out there.”

(A quick aside to my intimate friends of my Fabulous Friday Friends group:”I’m not talking about YOURS.” )

Let’s Talk About Bad Breakfast Casseroles

I’ve had some Breakfast Casserole Swill in my days.

Rubbery, greasy sausage, bobbing in a pool of incompletely cooked and slightly curdled eggs, with some, ‘Murican cheese all wadded up and squished together with cheap, store-bought, white trash bread.

~Uuuuurrrrrrrp~

You know. Because you’ve eaten it too! It leaves you with the taste of heartburn and regret, all day long, doesn’t it?

Friends, we can do better. We can do much, much, much – oh – SO much better!

And I’m just the gal to hook you up with the recipe of your dreams!

Please save this on Pinterest, and make it for your friends and family when company comes. You’ll be so grateful you did!

This is NOT that Breakfast Casserole.

This casserole reduced my Friday Friends Group to silence, punctuated by “Mmmmms” and sighs, and even a few groans of pleasure. Yes….it’s THAT good.

I’m calling for either Gruyère, or my favorite Cabot Cheese in this, Alpine Cheddar, because it tastes so much like Gruyère. But you can use White Cheddar, or Fontina, or Havarti, or any lovely melting cheese you like. I like Cabot’s Alpine Cheddar because it’s a little nutty, with a yodel.

Much like myself.

Make this recipe the night before your holiday breakfast or brunch, and take it out of the fridge and preheat your oven. You’ll have the breakfast of your dreams in an hour, and the only sadness and regret you’ll taste is that you didn’t make a second one.

Frozen spinach is really convenient to use in this recipe. I squeezed the water out of the thawed spinach using paper towels.

Holiday Breakfast Casserole with Gruyère is the perfect breakfast or brunch casserole when company's coming, because it's delicious, and is assembled the night before.

Prep Time 1 hour 30 minutes
Cook Time 1 hour
Additional Time 8 hours
Total Time 10 hours 30 minutes

Ingredients

  • 12-14 oz. baguette (I used one of the long baguettes from my Costco bakery), sliced into 1/2" thick slices
  • 15 oz. bag of frozen chopped spinach, thawed, and with water squeezed out (I used paper towels to help me squeeze out the water)
  • 9 and 1/2 T. butter
  • 2 large shallots, minced, (you need about 1 c. of minced shallots - mine were really large)
  • sea salt, and freshly ground black pepper
  • 1 cup medium-dry white wine, such as Sauvignon Blanc
  • 12 oz. Gruyère, or white cheddar, or Cabot Alpine Cheddar)
  • 12 eggs
  • 3 c. half and half

Instructions

  1. Adjust oven rack to middle position and heat oven to 225 degrees.
  2. Arrange bread in single layer on large baking sheet and bake until dry and crisp, about 40 minutes, turning slices over halfway through drying time. (Alternatively, leave slices out overnight to dry.)
  3. When cooled, butter slices on one side with 4 tablespoons butter; set aside.
  4. Heat 4 tablespoons butter in medium nonstick skillet over medium heat. Sauté shallots until fragrant and translucent, about 3 minutes; add spinach and salt and pepper to taste and cook, stirring occasionally, until spinach and shallots are combined, about 2 minutes.
  5. Transfer to medium bowl; set aside.
  6. Add wine to skillet, increase heat to medium-high, and simmer until reduced to 1/2 cup, 2 to 3 minutes; set aside.
  7. Butter 9 x 13" baking dish with 1 and 1/2 T. butter; arrange half the buttered bread slices, buttered-side up, in single layer in dish.
  8. Sprinkle half of spinach mixture, then half of grated cheese evenly over bread slices.
  9. Arrange remaining bread slices in single layer over cheese; sprinkle remaining spinach mixture and remaining 1/2 of cheese evenly over bread.
  10. Whisk eggs in medium bowl until combined; whisk in reduced wine, half-and-half, 1 teaspoon salt, and pepper to taste.
  11. Pour egg mixture evenly over bread layers; cover surface flush with plastic wrap, weigh down (see note, below), and refrigerate at least 1 hour or up to overnight. I refrigerated mine overnight.
  12. Remove dish from refrigerator and let stand at room temperature 20 minutes. Meanwhile, adjust oven rack to middle position and heat oven to 325 degrees.
  13. Uncover strata and bake until both edges and center are puffed and edges have pulled away slightly from sides of dish, 60 minutes. Cool on wire rack 5 minutes; serve.

Notes

To weigh down my assembled strata, I used a 7 lb. bag of confectioner's sugar, which is surely at the upper end of any weight you might need, but it worked perfectly for me. Just be sure your 9 x 13 pan is completely sealed with plastic wrap before you put your weight on top. You could also use a couple of 2 lb. bags of brown sugar, for example, or a couple of gallon-sized zipper-lock bags filled with about 2 pounds of sugar or rice as weights.
