Equipment

9x13-inch Baking Pan

Ingredients

1 pound mild or hot Italian sausage
2 large Everything Bagels cut into 1-inch pieces
1 ½ cups baby spinach
8 large eggs
1 ¼ cups whole milk
½ cup half-and-half
½ teaspoon salt
¼ teaspoon pepper
¼ teaspoon crushed red pepper flakes
1 cup shredded mozzarella cheese
⅓ cup freshly grated Parmesan cheese
6 ounces cream cheese

Instructions

Preheat oven to 350 degrees and grease a 9x13-inch baking dish.
Brown and crumble the sausage in a large nonstick pan over medium-high heat. Drain on a paper towel-lined plate.
Place the bagel pieces in the prepared baking dish.
Scatter the spinach evenly over the bagel pieces.
In a large bowl, whisk together the eggs, milk, half-and-half, salt, pepper, and crushed red pepper flakes.
Stir in both cheeses. Pour egg mixture evenly into the baking dish.
Add the sausage, spreading it evenly on top.
Cut the cream cheese into chunks and scatter them evenly on top.
Bake uncovered for 45 to 50 minutes. Let cool 5 minutes before slicing.

Notes

Can be assembled and stored in the refrigerator for up to 1 day in advance.

You can use breakfast sausage for this recipe, but I think Italian sausage pairs especially well with Everything bagels.
