How to Make Spinach Mushroom Strata

  1. Preheat oven to 350°F (175°C).
  2. Squeeze excess liquid from 10 oz (280g) fresh spinach and set aside.
  3. Melt 2 tablespoons butter in a large skillet over medium heat. Add 1 medium onion, chopped, and 8 oz (225g) sliced mushrooms. Cook until softened, about 5-7 minutes.
  4. Stir in 1/2 teaspoon salt, 1/4 teaspoon black pepper, and a pinch of nutmeg. Cook for 1 minute.
  5. Add the squeezed spinach, stir to combine, and remove from heat.
  6. In a lightly buttered 1 1/2 to 2-quart casserole dish, layer one-third of 6 cups (140g) cubed stale bread, then one-third of the spinach mixture, one-third of 4 oz (115g) grated Gruyere cheese, and one-third of 2 oz (55g) grated Parmesan cheese.
  7. Repeat layers twice, ending with a cheese layer.
  8. In a medium bowl, whisk together 3 large eggs, 1 1/2 cups (355ml) milk, and 1 teaspoon Dijon mustard.
  9. Pour the egg mixture evenly over the casserole.
  10. Let the strata sit for at least 15 minutes to allow the bread to absorb the liquid. (Optional: Refrigerate overnight for even better flavor).
  11. Bake for 45-55 minutes, or until golden brown and set in the center. Let stand for 10 minutes before serving.
