Equipment

Ingredients

16-20 ounces ground sausage pork, turkey, or chicken
10-16 ounces frozen spinach
2 cloves garlic minced
⅛ teaspoon red pepper flakes
6 large eggs
2 cups whole milk
2 teaspoons Diamond Crystal Kosher Salt
1 teaspoon black pepper
½ teaspoon garlic powder
12-14 ounces (about 6 slices) sourdough bread torn or cut into 1-inch pieces
2 cups shredded cheddar cheese

Instructions

In a large skillet over medium heat, brown the sausage until fully cooked. Add the frozen spinach, minced garlic, and red pepper flakes, cooking until the spinach softens and any excess liquid has evaporated. Remove from heat and let the mixture cool for about 30 minutes.
16-20 ounces ground sausage, 10-16 ounces frozen spinach, 2 cloves garlic, ⅛ teaspoon red pepper flakes
In a large bowl, whisk the eggs until smooth. Add the milk and seasonings and whisk again until everything is fully combined.
6 large eggs, 2 cups whole milk, 2 teaspoons Diamond Crystal Kosher Salt, 1 teaspoon black pepper, ½ teaspoon garlic powder
Generously butter an 8-inch square baking pan. Layer half of the torn or cubed sourdough bread on the bottom, then half of the sausage-spinach mixture, and half of the shredded cheddar cheese. Press down gently, then repeat with the remaining bread, sausage, and cheese. Slowly pour the egg mixture over the layers, letting it soak in. Cover tightly and refrigerate overnight, or for at least 6 hours.
12-14 ounces (about 6 slices) sourdough bread, 2 cups shredded cheddar cheese
When ready to bake, preheat the oven to 350℉. Let the strata sit at room temperature for 30 minutes while the oven heats. Place the baking pan on a baking sheet to catch any spills, then bake for 60–70 minutes, or until the eggs are fully set and the top is lightly golden.
Allow the strata to cool for 15–20 minutes before slicing into squares and serving.

Notes

Make Ahead: Assemble and refrigerate up to 24 hours before baking.
