HOW TO MAKE IT :
- Spray a 13 x 9-inch baking with cooking spray. Arrange 1/2 of the cubed bagels over the bottom of the dish.
- Mix the Asiago cheese with the mozzarella cheese and divide in half. Place 1/2 into a plastic bag and into the refrigerator.
- Sprinkle 1/2 of the bagel cubes with 1/2 of the cooked sausage, 1/2 of the sliced green onions and 1/2 of the shredded cheese mixture. Repeat reserving 1/2 of the cheese and 2 Tbsp green onion for garnishing.
- In a medium mixing bowl, whisk together the milk, heavy cream, beaten eggs, Parmesan cheese, salt, black pepper and ground mustard.
- Pour the custard over the bagels and sausage. Gently press the bread into the custard. Cover with plastic wrap and chill overnight.
- To prepare: Remove the plastic wrap and sprinkle the remaining shredded Asiago-Mozzarella cheese mixture on top. Preheat the oven to 350°F. Bake for 45-55 minutes until golden and puffed up. Let stand on the counter for 5 minutes.
- Garnish with reserved green onion before serving..
Notes :
Cube the bagels and leave on the cutting board on the counter for a couple of hours to dry out. This will ensure the bagel cubes absorb all of the custard.
