This hearty chicken bruschetta casserole transforms ordinary everything bagels into a comforting dinner that combines Italian bruschetta flavors with creamy chicken. The result is a crowd-pleasing meal that comes together with minimal effort but delivers maximum flavor.
I created this recipe when trying to use up leftover bagels and rotisserie chicken. What started as a kitchen experiment quickly became my most requested dish when hosting friends who always ask for my "fancy Italian casserole" without realizing how simple it really is.
Ingredients
- Everything bagels the star of the show with their savory seasonings that infuse the entire casserole
- Herb and garlic cream cheese creates a rich base that perfectly complements the bagel pieces
- Cooked shredded chicken use rotisserie chicken for convenience and extra flavor
- Roma tomatoes their firm texture holds up well during baking without making the casserole soggy
- Red onion adds a pleasant bite that balances the creaminess of the dish
- Basil pesto delivers concentrated herbal flavor without needing fresh herbs
- Mozzarella cheese forms that irresistible golden brown crust that makes casseroles so satisfying
Step-by-Step Instructions
- Preheat and Prepare Bagels
- Cut bagels into uniform bite sized pieces and arrange in a greased baking dish. Taking time to cut pieces evenly ensures they bake at the same rate and absorb the creamy sauce perfectly. I find that slightly stale bagels actually work better as they maintain their texture.
- Create Cream Base
- Heat cream cheese and cream over medium low heat while whisking constantly. Keep a watchful eye on this mixture as it can quickly go from perfect to scorched. The key is patience here cooking slowly creates the silkiest sauce that will coat every piece of chicken beautifully.
- Coat the Chicken
- Add shredded chicken to the cream mixture ensuring each piece is thoroughly enveloped in creamy goodness. This step creates the foundation of flavor as the chicken absorbs the richness of the sauce. Make sure your chicken is cool enough that it wont curdle the cream.
- Prepare Bruschetta Mix
- Gently combine tomatoes onion pesto and seasonings in a separate bowl. The magic happens when you let these ingredients mingle for a few minutes before adding to the casserole. Be gentle when mixing to maintain the integrity of the tomatoes.
- Assemble Your Masterpiece
- Layer bagels first followed by chicken mixture and bruschetta topping. The order matters here as it creates distinct layers of flavor and texture that meld together during baking while still remaining identifiable.
- Add the Cheese Crown
- Evenly distribute mozzarella over the entire surface. Make sure to cover all exposed areas this protective cheese layer prevents the tomatoes from drying out while creating that instagram worthy golden finish.
- Bake to Perfection
- Allow the casserole to bake until bubbling around the edges and golden on top. Your kitchen will fill with an irresistible aroma about 20 minutes in that makes waiting the full 30 minutes genuinely challenging.
- Rest Before Serving
- Let the casserole settle for 5 10 minutes before serving. This brief rest period allows the layers to set slightly preventing a sloppy serving experience and intensifying the flavors.

The tomatoes are truly the secret weapon in this recipe. I discovered that removing the seeds and juice prevents the dreaded soggy casserole syndrome that ruins so many good dishes. My grandmother always said good Italian cooking respects the tomato and this technique proves her right every time.
Make Ahead Magic
This casserole actually improves with time allowing the flavors to meld more completely. You can prepare everything up to the point of baking cover tightly with foil and refrigerate overnight. When ready to serve simply remove from the refrigerator 30 minutes before baking to take the chill off then bake as directed adding about 10 minutes to the cooking time.
Smart Substitutions
This recipe welcomes creative adaptations based on what you have available. Plain bagels work beautifully if everything bagels arent on hand. Leftover turkey rotisserie chicken or even canned chicken can be used in a pinch. For a vegetarian version substitute the chicken with roasted vegetables like zucchini eggplant and bell peppers. The cream cheese component can be lightened with Greek yogurt for those watching calories.
Serving Suggestions
This casserole shines when paired with a simple arugula salad dressed with lemon juice and olive oil. The peppery greens cut through the richness of the dish creating balance. For a complete meal add roasted asparagus or broccoli on the side. A glass of Pinot Grigio or Sauvignon Blanc complements the flavors beautifully making this humble casserole worthy of company.
Storage Solutions
Refrigerate leftover casserole in an airtight container for up to 3 days. The flavors actually improve overnight making this an excellent meal prep option. When reheating individual portions the microwave works well about 2 minutes on medium power. For larger portions reheat covered with foil in a 350°F oven for 15 20 minutes until heated through. While technically freezable the texture of the bagels does change somewhat when frozen and thawed.
