Step-by-Step Instructions

Prepare the Bagel Base

Cut bagels into uniform bitesize pieces and arrange in a single layer in your greased baking dish. This creates the foundation of your casserole. Fresh bagels work well but slightly stale ones actually absorb the flavors better. Make sure to cut the pieces small enough that they'll soften properly during baking around one inch is perfect.

Create the Creamy Sauce

Combine cream cheese and cream in a saucepan over medium low heat, whisking continuously until completely smooth. This takes about 3 to 4 minutes. The smooth texture is crucial for evenly coating the chicken, so be patient and keep whisking until no lumps remain. The mixture should be pourable but still thick enough to coat the back of a spoon.

Incorporate the Chicken

Add your cooked shredded chicken to the cream mixture, stirring gently until every piece is coated. This ensures flavor in every bite and creates a cohesive filling. The warmth of the sauce will help infuse the chicken with flavor. Let the mixture cool slightly before assembling to prevent the cheese from separating.

Prepare Fresh Bruschetta Topping

Mix together the diced tomatoes, red onion, basil pesto, seasonings, and parmesan in a bowl. Toss gently to maintain the texture of the tomatoes. This fresh component balances the richness of the creamy chicken mixture. The contrast between the warm, creamy chicken and the fresh, bright topping creates wonderful flavor complexity.

Assemble Your Creation

Layer the creamy chicken mixture over the bagel pieces, then top with the bruschetta mixture. Finish with an even layer of mozzarella cheese. Build your layers methodically, ensuring even distribution across the baking dish. This careful assembly ensures that every serving has the perfect balance of flavors.

Bake to Bubbly Perfection

Bake at 400°F for 30 minutes until everything is heated through and the cheese is golden and bubbly. Look for the edges to become slightly crispy and the center to be hot when tested with a fork. The high temperature ensures proper browning without overcooking the fresh toppings.

Rest Before Serving

Allow the casserole to rest for 5 minutes before serving. This resting period helps the layers set and makes serving much neater. The flavors also continue to meld during this time, improving the overall taste experience.

Save This

The first time I served this casserole, my skeptical teenager who claims to hate both tomatoes and onions cleaned his plate completely and asked for seconds. The everything bagel seasoning transforms ordinary ingredients into something truly special, and now I keep a shaker of the seasoning mix to sprinkle on top for even more flavor punch.

Make Ahead Options

This casserole shines as a make ahead meal option. You can prepare all components separately up to two days in advance, storing them in separate containers in the refrigerator. Assemble just before baking for the freshest result. Alternatively, assemble the entire casserole, cover tightly with plastic wrap and refrigerate for up to 8 hours before baking. If baking from cold, add about 10 minutes to the cooking time and cover with foil for the first 15 minutes to prevent over-browning.

Customization Ideas

The beauty of this recipe lies in its flexibility. For a lighter version, use light cream cheese and milk instead of cream. Vegetarians can substitute the chicken with sautéed mushrooms or white beans for protein. During summer, enhance the bruschetta topping with fresh herbs like basil, oregano, and parsley. For added texture, sprinkle with toasted pine nuts or breadcrumbs before baking. Feel free to use plain bagels if preferred, just add a teaspoon of everything bagel seasoning to maintain the signature flavor.

Perfect Pairings

This hearty casserole pairs beautifully with lighter sides to balance the meal. Serve alongside a simple arugula salad dressed with lemon vinaigrette to cut through the richness. Roasted asparagus or green beans make excellent vegetable accompaniments. For a more substantial meal, garlic bread might seem redundant with the bagel base, but crusty Italian bread is perfect for sopping up any extra sauce. A light, crisp white wine like Pinot Grigio complements the flavors beautifully for adult diners.

Storing Leftovers

Refrigerate leftovers in an airtight container for up to three days. The flavors actually improve overnight as they continue to meld. Reheat individual portions in the microwave for 2 minutes or until heated through. For best results when reheating larger portions, cover with foil and warm in a 350°F oven for about 15 minutes. The texture of the bagels softens further upon refrigeration, creating an almost bread pudding-like consistency that many find even more delicious than the original.

Common Questions

→ Can I use plain bagels instead of everything bagels?

Yes, you can substitute plain bagels or any flavor you prefer. Everything bagels add extra seasoning and flavor complexity, but plain, sesame, or even onion bagels work well too. Just note that changing the bagel type will slightly alter the final flavor profile.

→ How do I prevent the casserole from becoming soggy?

To prevent sogginess, ensure you remove seeds and excess juice from the tomatoes before adding them. Also, cut the bagels into uniform pieces and arrange them in a single layer. Finally, allow the casserole to cool slightly before serving, which helps it set properly.

→ Can I prepare this casserole ahead of time?

Yes, you can assemble the casserole up to 24 hours in advance and refrigerate covered. When ready to serve, allow it to sit at room temperature for 30 minutes before baking, and you may need to add 5-10 minutes to the baking time if cooking from cold.

→ What can I substitute for the cream cheese mixture?

If you prefer an alternative to cream cheese, you could use ricotta mixed with a little heavy cream or sour cream for a similar creamy texture. Greek yogurt mixed with a small amount of mayonnaise can also work as a tangier alternative.

→ How do I know when the casserole is fully cooked?

The casserole is done when the cheese on top is completely melted and starting to bubble, with some golden spots appearing. Insert a fork into the center - it should come out hot to the touch, indicating the casserole is heated through. The edges of the bagel pieces should also appear slightly toasted.

→ Can I freeze leftovers of this casserole?

Yes, leftovers can be frozen for up to 2 months in an airtight container. For best results, thaw overnight in the refrigerator before reheating. When reheating, cover with foil and bake at 350°F until heated through, removing the foil for the last few minutes to re-crisp the top.
