How to Prepare
Start by greasing a large baking dish and cutting the bagels into bite sized pieces. Spread the bagel cubes evenly across the dish. In a large bowl, whisk together the eggs, milk, cream, salt, and pepper until well combined. Stir in the shredded cheese, cooked meat, onion, and bell pepper. Pour this mixture evenly over the bagel cubes, making sure all pieces are coated. Gently press the bagels down to absorb the custard mixture. Cover with foil and refrigerate for at least 4 hours or overnight. When ready to bake, preheat your oven to 350°F, uncover the dish, and bake for 40 to 45 minutes until golden brown and cooked through. Let it rest for 5 to 10 minutes before serving.
Pro Tips
For best results, use slightly stale bagels since they absorb the egg mixture better without becoming soggy. If you prefer a richer flavor, swap half the milk with extra cream. You can also switch up the cheese with mozzarella, Swiss, or pepper jack for variety. To make the casserole vegetarian, omit the bacon or sausage and add more vegetables like spinach, mushrooms, or zucchini. Preparing the casserole the night before will save time and ensure all the flavors blend beautifully by morning.
Perfect Pairings and Toppings
This bagel breakfast casserole pairs wonderfully with a fresh fruit salad, roasted potatoes, or a light green salad for balance. For toppings, try a dollop of sour cream, salsa, or hot sauce for a flavorful kick. Fresh herbs such as parsley or chives add a nice touch of color and freshness. If you want something sweet on the side, pair it with pastries, muffins, or a refreshing glass of orange juice to round out the meal.
Conclusion
This delicious bagel breakfast casserole is the ultimate make ahead dish that brings comfort and convenience to your table. It is hearty, flavourful, and endlessly customizable, making it a recipe you will turn to again and again. Whether served at a family breakfast, holiday brunch, or weekend gathering, it is guaranteed to impress and satisfy everyone at the table.
