Oh, you’re going to love this one! Nothing beats the smell of everything bagel seasoning, sausage, and eggs baking together on a lazy Sunday morning. I first made this casserole when my sister visited last year—she took one bite and immediately demanded the recipe. Now it’s our go-to for family brunches and holiday mornings when we want something hearty but don’t want to stand over the stove. The best part? You just layer everything in the dish, pour over the egg mixture, and let the oven do the work. That incredible everything bagel flavor in every bite? Pure breakfast magic.

Trust me, this isn’t just another breakfast bake—it’s the one you’ll crave every weekend. Here’s why:

• Effortless mornings: Dump everything in the dish—no fancy techniques, just layers of goodness
• That addictive crunch: The bagel cubes toast up perfectly while staying tender inside
• Customizable: Swap in turkey sausage, add spinach, or go wild with different cheeses
• Feeds a crowd: Perfect for holiday brunches when you’d rather chat than cook
• Leftovers rock: Tastes even better reheated (if there’s any left!)

Seriously, that everything bagel seasoning makes every bite pop with garlic, onion, and sesame goodness. Breakfast just got a major upgrade.

Ingredients for Everything Bagel Sausage and Egg Casserole

Gather these simple ingredients – I promise you probably have most in your kitchen already! The magic happens when they all come together:

• 6 everything bagels – cut into 1-inch cubes (day-old works great here!)
• 1 lb breakfast sausage – cooked and crumbled (I use mild, but spicy would be delicious)
• 8 large eggs – farm-fresh if you can get them
• 2 cups whole milk – trust me, the richness matters
• 1 cup sharp cheddar cheese – freshly shredded (none of that pre-shredded stuff)
• 2 tbsp everything bagel seasoning – the star of the show!
• 1 tsp kosher salt – adjust to your taste
• ½ tsp black pepper – freshly ground if you’re feeling fancy

See? Nothing complicated – just good, honest ingredients that transform into something magical in the oven. Pro tip: measure out your everything bagel seasoning first – that way you won’t accidentally dump in too much (though is there really such a thing as too much?).

How to Make Everything Bagel Sausage and Egg Casserole

Okay, let’s get cooking! This is seriously one of the easiest breakfast dishes you’ll ever make. Just follow these simple steps and you’ll have a golden, bubbly casserole that’ll make your whole house smell amazing.

Prep the Baking Dish

First things first – grab your trusty 9×13 inch baking dish and give it a good greasing with butter or cooking spray. Don’t skip this step unless you want your beautiful casserole to stick! Now toss in those everything bagel cubes and spread them evenly across the bottom. I like to press them down slightly so they form a nice, sturdy base for all the goodness to come.

Layer the Ingredients

Next comes the fun part – sprinkle your cooked sausage crumbles evenly over the bagel cubes. Try to distribute them well so every bite gets some sausage love. Now, in a big bowl, whisk together your eggs, milk, salt, and pepper until they’re completely combined. Slowly pour this golden mixture over everything in the baking dish – take your time so it soaks in evenly. Finish with a generous sprinkle of cheese and that magical everything bagel seasoning (this is where the flavor really pops!).

Bake to Perfection

Pop that beauty into your preheated 350°F oven and let it work its magic for about 45-50 minutes. You’ll know it’s done when the edges are golden brown and the center doesn’t jiggle when you give the pan a gentle shake. Pro tip: If the top starts browning too quickly, just tent it with some foil. When it’s done, resist the urge to dive right in – let it rest for 5 minutes so everything sets up nicely. Then slice, serve, and watch those happy breakfast faces!

Tips for the Best Everything Bagel Sausage and Egg Casserole

After making this casserole dozens of times (okay, maybe hundreds – we’re obsessed), I’ve picked up some foolproof tricks:

• Day-old bagels are your friend: Slightly stale cubes soak up the egg mixture without getting mushy
• Prep the night before: Assemble everything, cover, and refrigerate – just add 5-10 minutes to baking time
• Cheese shield: Wait until the last 15 minutes to add cheese if you want a perfectly melted top
• Taste your seasoning: Some everything bagel blends are saltier than others – adjust accordingly
• Rest before slicing: Those 5 minutes make all the difference for clean cuts

Oh, and don’t be shy with that everything bagel topping – I always keep extra on the table for sprinkling!

Variations for Everything Bagel Sausage and Egg Casserole

One of my favorite things about this recipe? It’s like a blank canvas for your breakfast dreams. Here are some of my go-to twists when I’m feeling adventurous (or just cleaning out the fridge):

• Protein swap: Turkey sausage keeps it lighter, or try crumbled bacon for extra smokiness
• Veggie boost: Toss in sautéed mushrooms, spinach, or bell peppers when layering
• Cheese lovers: Swap cheddar for pepper jack, gruyère, or a three-cheese blend
• Bread options: No everything bagels? Use plain with extra seasoning, or try croissants for richness
• Spice it up: Add red pepper flakes or hot sauce to the egg mixture

The beauty is, as long as you keep that egg-to-bread ratio and everything bagel magic, you really can’t mess it up. My neighbor even made a version with diced ham and Swiss that had us all begging for the recipe!

Serving Suggestions

This casserole shines all on its own, but here’s how I love to serve it: a big leafy green salad cuts through the richness, while fresh fruit adds brightness. Keep hot sauce on the table for those who want extra kick – my brother drowns his in Cholula! For a full brunch spread, add crispy hash browns and mimosas. Leftovers (if you’re lucky enough to have any) make killer breakfast sandwiches the next day.

Storage and Reheating

Here’s the best part about this casserole – it actually gets better as leftovers! Just follow these simple storage tricks and you’ll have amazing breakfasts all week long.

Refrigerating: Let the casserole cool completely, then cover tightly with foil or transfer slices to airtight containers. It’ll keep beautifully in the fridge for 3-4 days. Pro tip – I like to portion it out so I can grab single servings quickly on busy mornings.

Freezing: Yes, you can freeze this! Cut cooled casserole into portions, wrap each tightly in plastic wrap, then foil. They’ll keep for 2-3 months. Thaw overnight in the fridge before reheating.

Reheating: My favorite method is the toaster oven – 325°F for about 10-15 minutes until heated through. The microwave works in a pinch (about 1-2 minutes per slice), but the edges won’t stay as crispy. If reheating a whole refrigerated casserole, cover with foil and bake at 350°F for 20-25 minutes.

Little secret? Sometimes I’ll make two – one to eat fresh, one to freeze for those “I can’t even” mornings. That everything bagel flavor holds up beautifully!

Nutritional Information

Now, I’m no nutritionist, but here’s the scoop on what’s in this deliciousness! (Remember – these are estimates and may vary based on your specific ingredients.) Per serving: about 420 calories, 22g protein to keep you full, and 30g carbs from those glorious bagel cubes. It’s got 24g fat (9g saturated) – but hey, that’s what makes it taste so good! The everything bagel seasoning adds about 890mg sodium, so you might want to go easy if you’re watching that. Fiber comes in at 2g thanks to the bagels. Not bad for breakfast that tastes this indulgent!

Frequently Asked Questions

I’ve gotten so many questions about this casserole over the years – here are the ones that pop up most often from friends and family (and random neighbors who smell it baking)!

Can I make this the night before?
Absolutely! That’s actually my favorite way to do it. Just assemble everything in the baking dish, cover tightly with plastic wrap, and refrigerate overnight. In the morning, take it out while the oven preheats (about 20 minutes) so it’s not ice cold when it goes in. Add 5-10 minutes to the baking time since it’s starting from fridge temp.

What if I can’t find everything bagels?
No worries – use plain bagels and double the everything bagel seasoning! You can also make your own blend with equal parts sesame seeds, poppy seeds, dried garlic, dried onion, and salt. I’ve even used English muffins in a pinch – just adjust the seasoning to taste.

How do I keep it from getting dry?
Three secrets: 1) Don’t overbake – pull it when the center just barely sets, 2) Use day-old (not fresh) bagels so they absorb moisture without turning mushy, and 3) Make sure your egg-to-milk ratio is spot on (that’s why I insist on whole milk for richness). If you’re really worried, you can add an extra egg or splash of milk.

Can I use different meats or make it vegetarian?
Of course! I’ve used turkey sausage, bacon, even diced ham with great results. For vegetarians, skip the meat and add sautéed mushrooms, spinach, or roasted red peppers instead. Just keep the total volume about the same so the texture stays perfect.

Why does it need to rest before cutting?
That 5-minute wait lets the eggs finish setting up so you get clean slices instead of a scrambled mess. Plus, it’s piping hot straight from the oven – this gives it time to cool to edible temperature! Trust me, it’s worth the patience.

Oh, I’d absolutely love to hear how this everything bagel sausage and egg casserole turns out for you!
