Servings 8


  • 3 tablespoons olive oil divided
  • 2 yellow onions thinly sliced
  • Kosher salt to taste
  • Freshly ground black pepper to taste
  • 2 cloves garlic minced
  • 2 teaspoons chopped fresh thyme
  • Pinch red pepper flakes
  • 12 ounces kale ribs discarded and leaves chopped
  • 2 tablespoons unsalted butter
  • ¼ cup all-purpose flour
  • cups whole milk divided
  • 1 cup heavy cream
  • ½ cup sour cream
  • 8 large eggs
  • 1- pound loaf crusty multigrain bread cut into 1-inch pieces
  • 2 pounds butternut squash peeled and diced
  • 1 cup grated smoked cheddar cheese divided


  • ►Warm 2 tablespoons olive oil in a large skillet over medium heat. Add onions, reduce heat to medium-low, and cook, stirring occasionally, until golden and caramelized, about 25 minutes. Season with salt and pepper. Stir in garlic, thyme, and red pepper flakes and cook for 1 minute.
  • ►Add remaining 1 tablespoon olive oil and kale. Increase heat to medium-high and cook, tossing, until kale is wilted and tender, about 5 minutes. Transfer mixture to a bowl to cool.
  • ►Melt butter in same skillet. Add flour, reduce heat to medium, and cook, whisking constantly, until a light golden paste forms. Whisk in 1 cup milk, season with salt and pepper, and cook, whisking, until mixture is very thick and no floury taste remains, 8 to 10 minutes. Remove from heat and whisk in heavy cream, sour cream, and remaining 1½ cups milk. Let cool for at least 10 minutes, then whisk eggs into mixture.
  • ►Heat oven to 325°F. Generously grease a 9-inch-by-13-inch baking pan.
  • ►Combine kale mixture, milk mixture, bread, butternut squash, and ½ cup smoked cheddar in a large bowl. Mix well and pour strata mixture into prepared baking dish. Let stand for 30 minutes, pressing down bread occasionally.
  • ►Bake strata for 55 minutes to 1 hour, until almost set. Increase oven temperature to 475°F. Sprinkle remaining ½ cup cheese on top and bake for about 10 minutes more, until top is lightly browned. Let strata stand for 15 minutes before serving.
