How to Make Everything Bagel Make Ahead Breakfast Casserole Recipe

Step 1: Prepare Your Dish

Start by greasing a 13×9 inch casserole dish thoroughly to ensure that nothing sticks, making for an easier cleanup later on and preserving the delicate layers you’re about to build.

Step 2: Layer the First Half

Place half of the everything bagel cubes into the bottom of the casserole dish. Then sprinkle half of the diced bacon evenly over the bagels. Follow up by adding half of the shredded Gruyere cheese to cover the layer, and finally, scatter half of the cream cheese cubes across the top.

Step 3: Build the Second Layer

Repeat the layering process with the remaining bagel cubes, bacon, Gruyere, and cream cheese. This layering ensures every bite is packed with the signature flavors of this flavorful casserole.

Step 4: Mix the Egg Custard

In a separate bowl, whisk together your eggs, heavy cream, salt, and pepper until the mixture is uniform and slightly frothy. This custard mixture is what will bind everything together, creating a luscious and creamy texture throughout the casserole.

Step 5: Combine and Soak

Pour the egg mixture carefully over your layered bagels, making sure each piece is soaked and submerged evenly. This step guarantees the casserole bakes up moist and custardy rather than dry.

Step 6: Refrigerate to Marinate

Cover the casserole tightly with plastic wrap or foil and refrigerate for at least 4 hours, or ideally overnight. This marinating time allows the bagels to absorb the egg custard, melding the flavors deeply for a more harmonious dish.

Step 7: Preheat and Prepare to Bake

When you’re ready to cook, preheat your oven to 350 degrees Fahrenheit. Cover the casserole with aluminum foil to keep it from browning too quickly while baking.

Step 8: Bake to Perfection

Bake the casserole covered for 40 minutes. Then remove the foil and bake for an additional 15 minutes. This process gives the dish that beautiful golden top and ensures the inside is perfectly set.

Step 9: Rest and Garnish

Allow your casserole to cool for about 10 minutes before serving. This resting time helps everything settle and makes it easier to slice and serve. Finish with a sprinkle of fresh chopped chives to add a pop of color and a gentle onion flavor.

How to Serve Everything Bagel Make Ahead Breakfast Casserole Recipe

Garnishes

Fresh chives aren’t just pretty—they add a subtle, aromatic sharpness that contrasts beautifully with the creamy, cheesy layers. You can also try a light drizzle of sour cream or a dollop of crème fraîche for added creaminess and tang.

Side Dishes

This casserole pairs wonderfully with fresh fruit salad to balance its richness. Crisp roasted potatoes or a simple green salad with a lemon vinaigrette are excellent accompaniments that bring brightness to the table.

Creative Ways to Present

Serve this casserole straight from the dish family-style or cut into neat squares for a brunch buffet. For a fun twist, try topping each portion with a sunny-side-up egg or a scattering of smoked salmon to complement the everything bagel flavors.

Make Ahead and Storage

Storing Leftovers

Refrigerate any leftover casserole tightly covered in an airtight container. It will stay fresh for up to 3 days and retains its delightful flavors well, making it an easy grab-and-go breakfast or snack.

Freezing

This casserole freezes beautifully if you want to extend its lifespan. Wrap individual portions or the whole dish tightly with plastic wrap and foil before freezing. It will keep for up to 2 months without losing its texture or flavor.

Reheating

Reheat leftovers in a 350-degree oven until warm throughout, typically 15-20 minutes. For a faster option, microwave individual servings, but keep in mind that the oven method preserves the crispy edges and creamy interior best.

FAQs

Can I use a different type of bagel for this casserole?

Absolutely! While everything bagels give this recipe its signature savory crunch, you can experiment with plain, sesame, or poppy seed bagels to suit your taste or what’s available.

How far ahead can I prepare the casserole?

You can assemble the casserole and refrigerate it for up to 24 hours before baking. This makes it perfect for prepping the night before a big breakfast or brunch event.

Is it possible to make this recipe vegetarian?

Yes, just skip the bacon and add some sautéed mushrooms or your favorite veggies to keep the savory richness without meat. Extra cheese or a sprinkle of smoked paprika can boost flavor.

Can I use a different cheese instead of Gruyere?

Gruyere melts beautifully and has a nutty flavor, but Swiss, mozzarella, or fontina are great alternatives that will still give you that creamy texture and mild cheesy taste.

What makes this an ideal make-ahead recipe?

This casserole is designed to be assembled ahead of time, allowing the flavors to meld and the bagels to soak up the custard. This makes mornings less rushed and mornings more delicious.
