Wake up to the tasty flavors of this everything bagel casserole! It's made with everything bagels and seasoning, sausage, eggs, cream cheese, and gruyère cheese. The result is a creamy and savory breakfast casserole that everyone will devour!
Preheat the oven to 375 degrees and spread the cut-up bagels on a parchment-lined baking sheet.
Toast the bagels in the oven for about 8 minutes, stirring them around about halfway through. Once dry and toasty, remove them from the oven and let the bagel pieces cool completely.
While the bagels cool, heat the cream cheese in a large bowl in the microwave for 20-30 seconds, until it is very soft. Use a hand mixer to beat the cream cheese until it is smooth. Slowly mix in the milk and everything bagel seasoning. Whisk the mixture until very smooth and creamy.
Whisk in the eggs and stir in the shredded gruyère cheese.
Once the bagel pieces are fully cooled, add them to a bowl with the cooked sausage and the egg mixture. Toss together until fully combined. Cover and set aside to soak for 15-20 minutes.
Meanwhile, preheat the oven to 350 degrees Fahrenheit and spray a 4-quart baking dish with pan spray.
After the mixture has soaked transfer it to the prepared dish and sprinkle the top with additional everything bagel seasoning. Bake for 30-35 minutes or until a knife comes out clean from the center and it doesn’t jiggle when you shake it gently.
Let the casserole sit for 5 minutes before garnishing with sliced green onions and serving.
