How To Make Bagel Breakfast Casserole

Want an adventurous breakfast? Well, take that egg and cheese bagel and make an exquisite bagel breakfast casserole! It’s fun, unique, and delicious.

Preparation: 20 minutes
Cooking: 45 minutes
Total: 1 hour 5 minutes

Serves:

Ingredients

  • 6pkgeverything bagels
  • 7large eggs
  • cupshalf and half
  • 1tspkosher salt
  • tspblack pepper
  • ½tbspvegetable oil
  • 1lbbreakfast sausage
  • 1red bell pepper,diced
  • 1small yellow onion,peeled and diced
  • 2tbspfresh parsley,chopped, divided
  • 3cupssharp cheddar cheese,shredded and divided

Instructions

  1. Preheat your oven to 350 degrees F, then lightly grease or butter a 13×9-inch casserole dish.

  2. Prep the bagels: Using a serrated bread knife, cut each bagel into bite-size pieces. I like to cut the bagel in half (from top to bottom) and then cut each half into fourths. Try to cut the bagel into pieces that are no larger than an inch.

  3. Make the egg mix and combine with the bagels: In a large mixing bowl, whisk together the eggs, half-and-half, salt, and pepper until no yolk is visible and the mixture is smooth. Add the cut bagels to the egg mixture and, using a large spoon or spatula, toss to coat the bread in the liquid. Set this to the side to allow the bread to soak while you brown the sausage.

  4. Cook the sausage, onion, and pepper: Heat the oil in a large skillet over medium-high heat until it begins to shimmer (this should take about a minute). Add the breakfast sausage to the pan and begin to brown it. Break up the sausage into small chunks with a wooden spoon until the sausage is about the size of pistachios. It should not look minced. Once the sausage has cooked through and browned (about 5 minutes), create a well in the center of the pan using your spoon. Add the diced peppers and the onions. Stir them with the sausage and cook the mixture for an additional 3 to 4 minutes, or until the veggies are glossy and soft. Drain any excess fat by straining the mixture in a colander, then allow the mixture to cool for 5 minutes. This is a great time to shred your cheese if you haven’t already.

  5. Combine the sausage, bagel and egg mixture. Once your sausage mix has cooled slightly, add it to the bagel and egg mixture. Add 1 tablespoon of the parsley and 2 cups of the cheddar cheese. Toss the ingredients together to combine evenly.

  6. Assemble the casserole: Pour the mixture into the prepared casserole dish and cover with aluminum foil. Make-ahead step: At this point, you can place the dish into the refrigerator overnight and bake in the morning. Once you’re ready to bake, remove the casserole dish twenty minutes prior to baking, then proceed as follows.

  7. Bake the casserole: Bake, covered with foil, in the preheated oven for 20 minutes and then carefully remove the pan from the oven and remove the foil. Return the pan to the oven and bake for an additional 25 minutes or until the middle is no longer jiggling, and the surface has browned.

  8. Cool and serve: Remove the pan from the oven and immediately top with the remaining cheese and parsley. Allow the casserole to cool for 10 minutes prior to serving.
