Instructions

Butter a 9×13-inch casserole dish and add the toasted bagel pieces.
In a large bowl, whisk together eggs, half and half, Dijon mustard, cayenne pepper, salt, and pepper until fully combined.
Pour the egg mixture evenly over the bagels, ensuring all pieces are coated.
Add Parmesan cheese and half of the cheddar, then gently toss to combine.
Distribute cream cheese cubes evenly over the casserole.
Top with diced sausage, bell pepper, and tater tots.
Sprinkle the remaining cheddar cheese over the top.
Cover and refrigerate for at least 4 hours or overnight.
Preheat oven to 350°F (175°C). Bake covered for 40 minutes.
Uncover and bake an additional 15 minutes until set and lightly golden.
Let cool for 10 minutes, garnish with green onions, and serve.

Notes

Longer overnight soaking results in a moister casserole.

Lightly toasting the bagels prevents sogginess.

Adjust cayenne or add jalapeños for more heat.

Swap cheeses such as pepper jack or mozzarella if desired.
