Bagel Casserole Ingredients

Discover everything you need for this delightful dish!

For the Casserole

  • Bagels – Fresh or stale bagels can be used; stale bagels absorb moisture better, enhancing the casserole’s texture.
  • Bacon – Adds a crispy, salty flavor that perfectly complements the softness of the bagels.
  • Onion – Use yellow or white onion for a savory depth of flavor.
  • Spinach – Fresh spinach adds nutrition and vibrant color; frozen spinach is a fine substitute.
  • Tomatoes – Adds moisture and acidity; canned diced tomatoes work well if fresh ones aren’t available.
  • Cheeses (e.g., cream cheese, cheddar) – Creaminess and flavor are key; cream cheese layers beautifully throughout the dish.
  • Eggs – Essential for binding the casserole together and creating that perfect texture.

  • Everything Bagel Seasoning – Provides a delightful flavor boost; pre-mixed versions are widely available.

Step‑by‑Step Instructions for Everything Bagel Casserole

Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This temperature ensures that your Everything Bagel Casserole will bake evenly and come out perfectly fluffy. While the oven warms up, gather your baking dish and prepare your ingredients, setting the stage for this comforting dish.

Step 2: Cook the Bacon and Onions
In a large skillet over medium heat, cook the diced bacon until crispy, which typically takes about 6–8 minutes. Once the bacon is done, remove it with a slotted spoon, leaving the bacon fat in the skillet. In the same skillet, add sliced onions and sauté until they’re translucent and fragrant, about 5 minutes. This step will bring a lovely depth of flavor to the casserole.

Step 3: Combine the Casserole Ingredients
In a large mixing bowl, combine chopped bagels, crispy bacon, sautéed onions, fresh spinach, diced tomatoes, and a generous handful of shredded cheese. Stir the mixture gently, ensuring that the bagels are well-coated in flavors. Transfer this delightful mixture to your prepared baking dish, spreading it evenly across the bottom.

Step 4: Prepare the Egg Mixture
In a separate bowl, whisk together the eggs, milk, and Everything Bagel Seasoning until fully combined. This egg mixture will bind the casserole, bringing everything together as it bakes. Carefully pour this mixture over the bagel mixture in your baking dish, ensuring all components are evenly moistened for a harmonious blend of flavors.

Step 5: Add Cream Cheese Chunks
Cut the cream cheese into small chunks and scatter them throughout the casserole mixture. These little pockets of creamy goodness will melt into the casserole, creating a delightful texture and enhancing the overall flavor. Distributing the cream cheese evenly will ensure that every bite of the Everything Bagel Casserole is rich and satisfying.

Step 6: Bake the Casserole
Place your filled baking dish in the preheated oven and bake for 45–55 minutes. Keep an eye on it as it bakes: the edges should become golden and crisp, while the center will begin to set but may still look slightly jiggly. This slight jiggle indicates that your casserole will remain moist once it cools.

Step 7: Cool and Serve
Once baked, remove the Everything Bagel Casserole from the oven and allow it to cool for about 10–15 minutes before slicing. This cooling period enhances the flavors and makes it easier to serve. Enjoy this hearty dish warm, perhaps topped with avocado for an added touch of creaminess!

Make Ahead Options

The Everything Bagel Casserole is a fantastic option for meal prep; you can prepare it up to 24 hours in advance for a hassle-free brunch! To do this, simply assemble the casserole following the instructions—layering the bagels, bacon, spinach, and cheese—then whisk the egg mixture and pour it over. Cover the dish tightly with plastic wrap and refrigerate. This not only saves you time but allows the flavors to meld together beautifully overnight. When you’re ready to serve, remove it from the fridge, let it sit at room temperature for about 30 minutes, and bake as directed. You’ll enjoy a deliciously convenient meal that tastes just as delightful!

What to Serve with Everything Bagel Casserole

As the savory aroma of the Everything Bagel Casserole fills your kitchen, consider these delightful pairings to elevate your meal experience.

  • Simple Green Salad: A refreshing mix of greens lightly tossed in a vinaigrette adds a crisp contrast to the creamy casserole. The lightness of the salad perfectly balances the hearty flavors.

  • Sliced Avocado Toast: Top whole grain toast with creamy avocado for a smooth complement. It adds a nutritious touch and pairs beautifully with the bagel flavors.

  • Roasted Brussels Sprouts: Their crispy edges and earthy taste enhance the richness of the casserole. The slight bitterness of Brussels sprouts creates a delicious harmony on your plate.

  • Fresh Fruit Salad: A medley of seasonal fruits brings sweetness and freshness to your brunch spread. The fruit’s juiciness acts as a refreshing palate cleanser after bites of rich casserole.

  • Chilled Sparkling Water: A bubbly beverage adds a celebratory touch to your meal, enhancing the flavors without overpowering them. Garnish with a lemon wedge for a zesty kick.

Expert Tips for Bagel Casserole

  • Even Size Matters: Ensure bagels are cut into uniform pieces to promote even cooking. Uneven sizes can lead to soggy or overly crispy bites.

  • Avoid Overbaking: Watch the casserole closely near the end of baking. A perfect bagel casserole should have a slightly jiggly center; overbaking leads to dryness.

  • Mix & Match Veggies: Don’t hesitate to add seasonal vegetables or other proteins. Experimenting with different ingredients could enhance your bagel casserole experience!

  • Cream Cheese Distribution: Cut the cream cheese into small chunks and distribute them evenly throughout the casserole to ensure pockets of creaminess in every bite.

  • Meal Prep Friendly: Prepare the casserole a day ahead, store it in the fridge, and bake before serving. The flavors meld beautifully overnight, making leftovers even more delightful!

  • Spice It Up: If you like a little kick, sprinkle in some red pepper flakes or jalapeños. The heat pairs beautifully with the creamy texture of the casserole.
