Ingredients

  • 1 tablespoon canola oil
  • 8 ounces sliced fresh mushrooms
  • 1/2 cup chopped onion
  • 2 cups fresh baby spinach
  • 2 garlic cloves, minced
  • 12 cups (about 8 ounces) cubed day-old French bread
  • 2 cups cubed deli ham
  • 8 ounces Brie cheese, rind removed and chopped
  • 8 large eggs
  • 3 cups 2% milk
  • 2 tablespoons Dijon mustard
  • 1/8 teaspoon salt
  • 1/8 teaspoon pepper

Method

  • Preheat oven to 375°. In a large skillet, heat oil over medium-high heat. Add mushrooms and onion; cook and stir until mushrooms are golden brown and onion is tender, 5-7 minutes. Add spinach and garlic; cook until spinach is wilted, 1-2 minutes longer.
  • Transfer mushroom mixture to a greased 13x9-in. baking dish. Add bread, ham and cheese.
  • In a large bowl, whisk eggs, milk, mustard, salt and pepper. Pour over bread. Bake, uncovered, until a knife inserted in the center comes out clean, 35-40 minutes. Let stand 5-10 minutes before serving.
  • Refrigerate unbaked strata, covered, several hours or overnight. To use, preheat oven to 375°. Remove strata from refrigerator while oven heats. Bake, as directed.
