Ingredients

Units Scale

For the Filling:

  • 1/4 pound pancetta, thick-cut and diced small
  • 1/2 pound ground Italian sausage (mild or spicy)
  • 1/2 medium red onion, diced
  • 1 tablespoon minced garlic (approximately 3 cloves)
  • 4 cups baby spinach, loosely packed

For the Strata Base:

  • 1 loaf Italian bread (1416 ounces), stale and cut into 1-2-inch cubes
  • 8 ounces fontina cheese, shredded

For the Custard:

  • 3 cups whole milk
  • 10 large eggs
  • 1 tablespoon Italian seasoning
  • 1/2 teaspoon kosher salt
  • 1/2 teaspoon black pepper

Instructions

  • Prepare the Filling:
    • Preheat a large skillet over medium heat.
    • Add pancetta, sausage, red onion, and garlic.
    • Sauté for 5–7 minutes, or until the meat is browned and cooked through.
    • Stir in baby spinach and cook until wilted. Remove from heat.
  • Assemble the Strata:
    • Butter or grease a 9×13-inch casserole dish.
    • Layer half of the bread cubes evenly in the bottom of the dish.
    • Add half of the cooked meat mixture and half of the shredded fontina cheese.
    • Repeat the layers with the remaining bread, meat mixture, and cheese.
  • Make the Custard:
    • In a large bowl, whisk together milk, eggs, Italian seasoning, salt, and black pepper until well combined.
  • Combine and Chill:
    • Pour the custard mixture evenly over the layered ingredients in the casserole dish.
    • Gently press the bread down to ensure it absorbs the custard.
    • Cover tightly with plastic wrap and refrigerate overnight (at least 8 hours).
  • Bake the Strata:
    • Preheat your oven to 350°F (175°C).
    • Remove the strata from the refrigerator and let it sit at room temperature for 10–15 minutes.
    • Bake uncovered for 50–60 minutes, or until the top is golden brown and the custard is set.
  • Rest and Serve:
    • Let the strata rest for 10 minutes before slicing and serving.

Notes

  • Bread Tip: Using slightly stale bread helps it absorb the custard better. If your bread is fresh, toast the cubes lightly in the oven before assembling.
  • Cheese Options: Swap fontina for mozzarella or Gruyère if desired.
  • Make-Ahead Convenience: Perfect for meal prep or holiday mornings when you need a fuss-free breakfast option.
