What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most of these are pantry staples or things you probably have in your fridge already.

• Everything bagels – 4 large, cut into 1-inch cubes (stale or day-old work best for soaking up the custard)
• Cream cheese – 8 ounces, softened (I prefer Philadelphia for that classic creamy tang)
• Eggs – 6 large, room temperature (for the custard base)
• Milk – 2 cups (whole milk gives a richer result, but 2% works fine)
• Shredded cheddar cheese – 1 cup (sharp cheddar adds great flavor, but you can mix with mozzarella for a milder taste)
• Everything bagel seasoning – 2 tablespoons (store-bought or homemade blend of sesame seeds, poppy seeds, dried garlic, dried onion, and salt)
• Salt – 1 teaspoon (balances flavor)
• Black pepper – ½ teaspoon, freshly ground
• Butter – 2 tablespoons, melted (for greasing the baking dish and adding richness)
• Optional add-ins: diced green onions or chives for freshness, cooked bacon or sausage for a meaty twist

For a dairy-free option, swap cream cheese with a plant-based alternative and use almond or oat milk. You can also substitute gluten-free bagels if needed. The beauty of this casserole is its flexibility, so feel free to make it your own!

Equipment Needed

• 9×13-inch baking dish: Standard size for casseroles; glass or ceramic works well to evenly distribute heat.
• Mixing bowls: One large bowl for the custard and another for tossing the bagel cubes.
• Whisk: Essential for beating eggs and mixing the custard until smooth.
• Measuring cups and spoons: For precise ingredient amounts.
• Spatula or wooden spoon: For folding ingredients together gently.

If you don’t have a whisk, a fork will do in a pinch, though it takes a bit more elbow grease. I’ve used everything from hand mixers to just a fork for this recipe, and honestly, they all work fine as long as the custard is well combined. For budget-friendly baking dishes, thrift stores or discount kitchenware shops often have great options.

Preparation Method

1. Preheat the oven to 350°F (175°C). Lightly grease your 9×13-inch baking dish with melted butter to prevent sticking and add flavor. This usually takes 3-5 minutes.
2. Prepare the bagel cubes: Cut the everything bagels into roughly 1-inch pieces. You want chunks that will soak up the custard but still hold some texture once baked.
3. Mix the custard base: In a large bowl, whisk together 6 large eggs and 2 cups of milk until fully combined and slightly frothy, about 2 minutes. Add the softened cream cheese in spoonfuls, whisking quickly to break it up and create a creamy custard. Don’t worry if small bits remain—they’ll melt during baking.
4. Add seasoning: Stir in 1 teaspoon salt and ½ teaspoon freshly ground black pepper. If you like a little extra zing, a pinch of smoked paprika or garlic powder can’t hurt.
5. Combine bagels and cheese: Gently fold in the bagel cubes and 1 cup shredded cheddar cheese into the custard mixture until everything is coated evenly. At this point, if you want to add diced green onions or cooked bacon, toss them in.
6. Transfer to baking dish: Pour the entire mixture into your greased baking dish, spreading it out evenly. Sprinkle 2 tablespoons of everything bagel seasoning generously over the top for that signature crunch and flavor.
7. Bake uncovered for 40-45 minutes, or until the casserole is puffed up, golden brown on top, and a toothpick inserted in the center comes out clean. The edges should be slightly crispy while the middle remains creamy.
8. Rest before serving: Let the casserole sit for about 10 minutes to set and cool slightly. This helps the flavors meld and makes cutting easier.

Tip: If you notice the top browning too quickly, loosely cover with foil halfway through baking. Also, if your cream cheese isn’t soft enough, microwave it for 15-20 seconds before mixing to avoid lumps.

Cooking Tips & Techniques

Here are some practical tips I’ve learned from making this creamy everything bagel breakfast casserole with cream cheese over and over:

• Use Day-Old Bagels: Fresh bagels can get soggy fast. Slightly stale bagels soak up the custard better without falling apart—trust me on this one.
• Room Temperature Ingredients: Bringing eggs and milk to room temp helps the custard blend smoothly and bake evenly, preventing curdling or uneven texture.
• Softened Cream Cheese: Don’t skip this step! It ensures the cream cheese incorporates well into the custard. I sometimes forget and end up with lumps—definitely less appetizing.
• Everything Bagel Seasoning: Sprinkle it on top last so it crisps up nicely. You can even toast it in a dry skillet before adding for an extra nutty flavor.
• Watch Your Oven: Ovens vary, so start checking around 35 minutes. The casserole should be golden but still moist and creamy inside.
• Multitask: While the casserole bakes, prep your coffee or fresh fruit to make brunch feel complete without extra time.

Variations & Adaptations

This casserole is super versatile, so you can switch it up to suit different tastes or dietary needs:

• Vegetarian Version: Skip the bacon or sausage and add sautéed mushrooms, spinach, or roasted red peppers for a veggie boost.
• Low-Carb Option: Replace bagels with cubed cauliflower bread or use a low-carb bagel alternative. The creamy custard keeps the dish rich and satisfying.
• Spicy Twist: Add diced jalapeños or a dash of hot sauce to the custard for a subtle kick that pairs beautifully with the everything bagel flavors.
• Dairy-Free Adaptation: Use dairy-free cream cheese and plant-based milk (like almond or oat milk). Nutritional yeast can replace cheese if desired.
• Personal Favorite: I once made this with smoked salmon chunks and fresh dill, which gave it a brunchy, elegant vibe without complicating the base recipe.

Serving & Storage Suggestions

This creamy everything bagel breakfast casserole is best served warm, ideally fresh from the oven with a crisp green salad or fresh fruit on the side. A light squeeze of lemon over the top adds a nice brightness, especially if you included bacon or smoked salmon.

Leftovers? No problem! Cover tightly and refrigerate for up to 3 days. To reheat, warm individual portions in the microwave for about 60-90 seconds or bake covered at 325°F (160°C) for 15-20 minutes until heated through. The flavors actually deepen after resting, so it’s perfect for make-ahead brunches.

If you want to freeze, wrap portions tightly in foil or plastic wrap and store in an airtight container for up to 2 months. Thaw overnight in the fridge before reheating.
