• Heat oven to 400°F. Grease 13×9-inch (3-quart) baking dish. Cook sausage, bell pepper and onion in 10-inch skillet over medium heat, stirring occasionally, until sausage is no longer pink; drain. Stir together sausage mixture, potatoes and 1 1/2 cups of the cheese in baking dish.
  • Stir Bisquick™ mix, milk, pepper and eggs until blended. Pour into baking dish.
  • Bake uncovered 40 to 45 minutes or until knife inserted in center comes out clean. Sprinkle with remaining cheese. Bake 1 to 2 minutes longer or just until cheese is melted. Cool 5 minutes.

Tips from the Betty Crocker Kitchens

  • Make up to 24 hours ahead, covering and refrigerating the casserole until 15 minutes before baking. Remove from the fridge while the oven heats up, then keep an eye on the doneness as it may take a few minutes longer since the food is chilled.
