Ingredients

  • 2 tablespoons olive oil plus more for the baking dish
  • 1 16-ounce French baguette cubed
  • 1 onion thinly sliced
  • 1 teaspoon salt divided
  • 1 teaspoon black pepper divided
  • 1 8-ounce container baby bella mushrooms sliced
  • 6 cups kale chopped
  • 2 teaspoons Italian seasoning
  • 10 eggs
  • 2 cups milk
  • 1 ½ cups shredded cheddar cheese divided

Instructions

  • Lightly oil a 9x13-inch baking dish and set bread cubes inside, set aside.
  • Add olive oil to a large sauté pan and set over medium heat. Add onion and ½ teaspoon salt and cook for 5 minutes. Add mushrooms and ½ teaspoon of pepper and cook for an additional 5 minutes. Add kale and Italian seasoning, and cook for 2 minutes, or until slightly wilted. Add vegetable mixture to the prepared pan with the bread and stir to gently distribute.
  • In a large bowl, whisk together eggs, milk, and remaining salt and pepper until well-blended. Add 1 cup cheddar cheese and stir to combine.
  • Pour the egg mixture over the bread and vegetables and sprinkle the remaining cheddar cheese, then cover tightly with foil. Let sit in the fridge overnight.
  • When ready to bake, preheat the oven to 350˚F. Bake, tightly covered in foil, for 40 minutes. Uncover and bake for an additional 15 minutes, or until the center is puffy and the top is golden brown.
  • Let cool slightly before cutting into squares and serving.

Notes

Tip: For the best texture and taste, let your strata sit overnight in the fridge.
