Bacon Mushroom Swiss Breakfast Strata Recipe

Step 1: Adjust oven rack to middle position and preheat oven to 275°F. Spread bread in an even layer on a rimmed baking sheet, and bake until completely dried, about 35 minutes. Rotate baking sheet and stir bread cubes several times during baking. Remove from oven and allow to cool.

Step 2: In a 12-inch cast iron skillet, warm up the bacon over medium heat, stirring frequently, until crisp, about 5 minutes. Using a slotted spoon, transfer bacon to a paper towel-lined plate to drain. Add mushrooms, season light with salt and pepper and cook. Stir occasionally until tender, about 5 minutes. Add spinach and cook Stir occasionally until wilted but still vibrant in color, about 3 minutes. Remove from heat and allow to cool.

Step 3: In a large bowl, whisk together eggs, milk, heavy cream, Dijon, thyme, ¾ teaspoon salt, pepper and nutmeg until well combined. Add the dried bread and fold gently to combine. Let soak until bread is softened and slightly puffed, folding occasionally with a flexible spatula, at least 15 minutes and no more than 30 minutes.

Step 4: Grease an 8-inch square ceramic or anodized aluminum baking dish with butter. Using a slotted spoon, add half of the soaked bread to the prepared baking dish, spreading it in an even layer. Top with half of the spinach and mushroom mix, half of the bacon, and half of the Swiss cheese. Repeat with remaining bread, spinach, mushrooms, bacon, and cheese. Pour any remaining custard over the layered strata. Using a flexible spatula, gently press down the top of the strata so that all the layers are submerged in the custard, but take care to not compress the bread. Cover tightly with aluminum foil. Allow strata to stand at room temperature for 30 minutes. Meanwhile, increase oven temperature to 325°F.

Step 5: Bake strata until cheese is slightly melted, about 20 minutes. Remove foil, return baking dish to oven, and continue to bake until strata is puffed and the center no longer jiggles when shaken, about 30 minutes. Remove from oven.

Step 6: Adjust oven rack to 6 inches below broiler element and preheat broiler on high. Broil until surface of strata is lightly browned in spots, about 2 minutes. Transfer to heatproof surface and allow to cool for 10 minutes. Cut into portions and serve.
