Ingredients

  • 6 everything bagels lightly toasted
  • 8 large eggs
  • 1 cup half and half
  • Salt/pepper to taste
  • 2 tablespoons Dijon mustard
  • 1/3 teaspoon cayenne pepper
  • ½ cup Parmesan shredded
  • 1 cup grated cheddar divided
  • 8 oz. cooked sausage links diced
  • ½ bell pepper diced
  • 8 oz. cream cheese
  • 1 cup tater tots
  • Green Onions to garnish

Instructions

  • Break the bagels into bite-sized pieces and place into a buttered 9x13 casserole dish.
  • In a large bowl, crack the eggs. Add the half and half, mustard, cayenne pepper, and salt/pepper. Whisk briskly for 1 minute.
  • Pour the egg mixture over the bagel pieces, try to cover each one.
  • Add the Parmesan cheese and ½ cup cheddar cheese to the casserole dish. Use a spoon to gently toss the casserole mixture.
  • Cut the cream cheese into 14 squares.
  • Distribute the top of the casserole with the cream cheese, sausage, bell peppers, and tator tots.
  • Top with the remaining half of cheddar cheese.
  • Cover and refrigerate for 4 hours or overnight. The longer it sits, the better/moister it will be.
  • Bake, covered, at 350 degrees for 40 minutes.
  • Remove the cover and bake for 15 more minutes.
  • Let cool for 10 minutes. Serve with coffee and enjoy!

Notes

*Lightly toasted bagels are able to absorb the custard much better, but still have all of the flavor that fresh bagels have. Stale bagels can also be used but I prefer fresh and toasted!
