This take on a classic casserole is hearty but won’t weigh your guests down. Gruyère, sausage, and kale is a great seasonal combo; swapping in wholegrain bread adds extra nutrition and staying power. Assembling everything the night before gives the bread the chance to soak up the liquid.

Ingredient Checklist


Instructions Checklist
  • Heat oil in a large nonstick skillet over medium-high. Add sausage and onion; cook, stirring often, until sausage is browned and onion is tender, 6 to 8 minutes. Stir in kale, and cook until wilted, about 1 minute. Remove from heat, and let cool 5 minutes.

  • Whisk together milk, mustard, salt, pepper, and eggs in a large bowl.

  • Combine bread cubes and sausage mixture in a 9x13-inch baking dish coated with cooking spray. Pour milk mixture evenly over bread mixture, pressing gently to submerge bread in liquid. Sprinkle evenly with cheese; cover with lightly greased (with cooking spray) aluminum foil, and chill at least 8 hours or up to overnight.

  • Remove dish from refrigerator; let stand 30 minutes. Preheat oven to 350°F. Bake in preheated oven, covered, for 30 minutes. Uncover and bake until lightly browned and set, about 15 minutes. Let stand 10 minutes before serving.

  • Prep this the day before—and sleep in a little the next morning!
