What makes this casserole different? It’s the use of everything bagel seasoning sprinkled generously on top and mixed through the bread pieces, which gives you that signature garlicky, oniony, poppy seed flavor in every bite. And instead of just plain bread, using day-old bagels or bagel-like bread chunks gives the casserole a unique texture with a little chew and crunch. I’ve also found that mixing in cream cheese chunks adds a luscious creaminess that melts into the eggs perfectly — a trick I picked up from making creamy bread bowls.

This casserole is comfort food reimagined — hearty, a little fancy, but fast enough to fit into a busy morning. It’s the kind of dish that invites you to linger over breakfast, even when you’re in a rush.

What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most are things you might already have in your kitchen, and there’s plenty of wiggle room for substitutions if needed.

• Everything Bagels or Bread: About 4-5 bagels, cubed into roughly 1-inch pieces (day-old or slightly stale works best for soaking up the custard)
• Eggs: 8 large eggs, room temperature (for that fluffy, firm bake)
• Milk or Half-and-Half: 2 cups (480 ml) — whole milk for creaminess or half-and-half for richer custard
• Cream Cheese: 4 ounces (110 grams), cut into small cubes (adds luscious, melty pockets)
• Shredded Cheese: 1 ½ cups (about 170 grams) sharp cheddar or a blend of cheddar and Monterey Jack (for melty, gooey goodness)
• Everything Bagel Seasoning: 2 tablespoons, plus extra for sprinkling on top (I love Trader Joe’s or Trader Joe’s-style homemade mix)
• Green Onions: 3, thinly sliced (for freshness and mild onion bite)
• Garlic Powder: ½ teaspoon (to deepen the savory notes)
• Salt and Pepper: To taste, but keep it light since the seasoning mix is salty
• Butter or Nonstick Spray: For greasing the baking dish

Ingredient tips: If you can’t find everything bagels, use any dense, chewy bread like sourdough or French bread and sprinkle generously with everything bagel seasoning. For dairy-free options, swap milk for almond or oat milk and use vegan cream cheese and cheese alternatives. The key is balancing that savory, garlicky flavor with creamy textures.

Equipment Needed

• 9×13-inch Baking Dish: A glass or ceramic dish works well for even baking. I prefer glass because it browns the edges nicely.
• Large Mixing Bowl: To whisk eggs and milk together effortlessly — a big bowl helps avoid spills when whisking.
• Whisk or Fork: For beating the eggs and mixing the custard.
• Measuring Cups and Spoons: Precision counts here, especially with seasoning and liquids.
• Knife and Cutting Board: For cubing bagels and chopping green onions.
• Rubber Spatula or Wooden Spoon: To fold cream cheese and cheese into the mixture gently.

If you don’t have a 9×13 dish, a similarly sized casserole dish is fine, just keep an eye on baking time. For greasing, butter works best for flavor, but nonstick spray is a handy shortcut. I’ve also used disposable aluminum pans when bringing this to brunch potlucks — easy cleanup and no worries.

Preparation Method

1. Preheat your oven to 350°F (175°C). Butter or spray your 9×13-inch baking dish liberally to prevent sticking and help the edges crisp up.
2. Cube the everything bagels. Cut into roughly 1-inch pieces — not too small, or they’ll get mushy; not too big, or they’ll stay dry. Toss the cubes in a large bowl with 2 tablespoons of everything bagel seasoning, ensuring each piece is nicely coated.
3. In a separate large bowl, whisk together 8 large eggs and 2 cups (480 ml) of milk or half-and-half.
4. Fold in the cream cheese cubes and shredded cheese.
5. Add the everything bagel cubes and sliced green onions to the egg mixture.
6. Pour the entire mixture into your prepared baking dish.
7. Bake uncovered for 35-40 minutes.
8. Let it rest for 5-10 minutes before cutting.

Pro tip: If your casserole feels too wet, next time try slightly less milk or bake a few minutes longer. The texture should be custardy but not soggy — think soft scramble meets bread pudding. You’ll know it’s done when the edges pull away slightly from the pan and the top is golden brown with a slight crust.

Cooking Tips & Techniques

Getting the perfect texture for this casserole can be a bit of a balancing act, but a few tricks helped me avoid common pitfalls:

• Use slightly stale bagels: Fresh bread soaks up the custard too quickly and turns mushy. Let the bagels sit out for a day or toast them lightly.
• Room temperature eggs and milk: Cold eggs from the fridge can cause uneven baking and curdling.
• Don’t overmix: Folding gently keeps the bread pieces intact and the custard fluffy.
• Season well but carefully: Everything bagel seasoning is salty, so adjust added salt sparingly.
• Timing is everything: If you want to prep ahead, assemble the casserole the night before and refrigerate overnight. Bake fresh in the morning for a hands-off start.
• Multitask while baking: This casserole gives you a golden 40-minute window — perfect time to whip up coffee, prep fruit, or even bake a quick one-bowl strawberry cake for a sweet finish.

One lesson I learned the hard way: underbaking leads to a runny mess, so if your knife comes out with wet custard, give it 5-10 more minutes. You can cover it with foil if the top looks too dark.

Variations & Adaptations

This casserole is a great base for customizing to your taste or dietary needs. Here are a few ways I’ve played around with it:

• Vegetarian option: Add sautéed mushrooms, bell peppers, or spinach for extra veggies without changing the core flavors.
• Meaty twist: Mix in cooked sausage, bacon bits, or diced ham to turn it into a hearty breakfast feast.
• Gluten-free: Swap bagels for gluten-free bread cubes, and double-check your everything bagel seasoning is GF-friendly.
• Spicy kick: Add a pinch of red pepper flakes or diced jalapeños for those who like a little heat.
• Dairy-free: Use almond or oat milk and vegan cream cheese and cheese alternatives to suit dietary restrictions.

My personal favorite twist lately has been adding caramelized onions and swapping cheddar for smoked gouda for that deep, smoky flavor — perfect for cozy weekend mornings. If you love casseroles like this, you might appreciate the cozy vibes in our southern loaded squash casserole, which pairs well on a brunch table.

Serving & Storage Suggestions

This casserole is best served warm, right out of the oven — ideally with a crisp green salad or fresh fruit to balance the richness. I like to garnish with extra sliced green onions or a sprinkle of fresh herbs like parsley for a pop of color and freshness.

To store leftovers, cover tightly with foil or plastic wrap and refrigerate for up to 3 days. Reheat in a 350°F (175°C) oven for 10-15 minutes to bring back that crispy crust, or microwave slices on medium power for about 1-2 minutes (though the crust will soften).

It also freezes well — portion into airtight containers and freeze for up to 2 months. Thaw overnight in the fridge before reheating. The flavors meld nicely, and the casserole tastes even better the next day, making it perfect for meal prep or easy breakfasts throughout the week.

Nutritional Information & Benefits

Here’s an estimate per serving (1/8 of the casserole): approximately 320 calories, 20g protein, 18g fat, 20g carbohydrates, and 2g fiber. The protein comes mainly from eggs and cheese, making it a satisfying start to the day that keeps you full longer.

The eggs provide essential nutrients like vitamin D, B12, and choline, while the everything bagel seasoning adds flavor without excess calories. Using whole milk or half-and-half adds richness along with calcium and vitamin A.

This recipe is naturally gluten-containing unless you swap the bread, so keep that in mind for gluten sensitivities. It can be tailored for low-carb or dairy-free diets with simple ingredient swaps.

From my wellness perspective, this casserole strikes a nice balance — it’s comforting without being heavy, and the combination of protein and carbs fuels busy mornings well. It’s a great alternative to sugary cereals or rushed takeout breakfasts.

It’s simple, forgiving, and packed with flavor — perfect for those mornings when you want something homemade but don’t have the luxury of time. Whether you stick to the classic version or try one of the variations, it’s a dish that invites you to slow down, enjoy, and savor breakfast again.
