What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to pack a punch of flavor—plus, it’s a great way to use up leftovers!

• Everything bagels: 4-5 bagels, cut into bite-sized pieces (stale bagels work perfectly).
• Eggs: 8 large eggs, beaten (you can use a whisk or fork).
• Milk: 2 cups whole milk (or substitute with almond milk for a dairy-free option).
• Shredded cheese: 1 ½ cups cheddar, mozzarella, or your favorite cheese blend.
• Breakfast sausage or bacon: 1 cup cooked and crumbled (can substitute with plant-based sausage for a vegetarian twist).
• Vegetables: 1 cup chopped onions, bell peppers, or spinach (feel free to mix and match).
• Cream cheese: 4 oz, cubed (adds creaminess and tangy flavor).
• Everything Bagel seasoning: 2-3 tablespoons for that signature flavor.
• Salt and pepper: To taste.

You can also add extras like chopped chives, diced tomatoes, or even hot sauce to give it a little kick. The beauty of this recipe is its versatility—you can use what you have on hand and adjust it to match your taste preferences.

Equipment Needed

• 9×13 baking dish: This size works perfectly for the recipe, but you can adjust to a smaller or larger dish with minor modifications.
• Mixing bowls: One large bowl for whisking your eggs and milk, and another smaller one for preparing other ingredients.
• Whisk: For beating eggs and combining the liquid ingredients.
• Knife: To slice your bagels and chop any veggies or meats.
• Cutting board: A sturdy surface for prepping your ingredients.
• Aluminum foil: Helps to cover the dish during baking if needed.

If you don’t have a 9×13 baking dish, you can use a deep pie dish or even a disposable foil pan for easy cleanup. For slicing bagels, a serrated bread knife works best to avoid squishing them.

Preparation Method

1. Preheat your oven: Set your oven to 350°F (175°C) and lightly grease your 9×13 baking dish with cooking spray or a thin layer of butter.
2. Prepare the bagels: Slice your everything bagels into bite-sized chunks. If your bagels are fresh, leave them out for a few hours to dry out, or toast them lightly.
3. Cook the meat: If using breakfast sausage or bacon, cook it in a skillet over medium heat until browned and crispy. Remove from heat and crumble or chop into small pieces.
4. Mix the egg mixture: In a large bowl, whisk together the eggs, milk, and a pinch of salt and pepper until fully combined.
5. Assemble the casserole:
   – Spread the bagel pieces evenly across the bottom of the greased baking dish.
   – Sprinkle the cooked sausage or bacon over the bagel pieces.
   – Add your chopped vegetables, spreading them out evenly.
   – Distribute the cubed cream cheese across the top.
   – Pour the egg mixture evenly over the assembled ingredients.
   – Sprinkle the shredded cheese and everything bagel seasoning on top.
6. Bake: Place the casserole in the preheated oven and bake for 40-45 minutes or until the eggs are set and the top is golden brown.
7. Cool and serve: Allow the casserole to cool for 5-10 minutes before slicing and serving.

Pro Tip: If your bagels are super fresh, drying them out overnight ensures they soak up the egg mixture better for a fluffy texture. Alternatively, lightly toast them in the oven before assembling the casserole.

Cooking Tips & Techniques

Here are some helpful tips to make sure your Irresistible Everything Bagel Breakfast Casserole turns out perfectly every time:

• Don’t skip drying the bagels: Stale or toasted bagels absorb the egg mixture better and give the casserole a light, fluffy texture.
• Use fresh ingredients: Fresh vegetables and high-quality cheese make a world of difference in flavor.
• Don’t overbake: Keep an eye on the casserole as it bakes—once the eggs are set and the top is golden brown, it’s ready to come out.
• Customize wisely: While this recipe is forgiving, avoid adding too many watery ingredients (like tomatoes or zucchini) without first draining them to prevent a soggy casserole.
• Prep ahead: Assemble the casserole the night before, cover, and refrigerate. In the morning, simply pop it in the oven for a hassle-free breakfast.

One thing I learned the hard way is that overloading on toppings can make the casserole unevenly cooked. Less is more when it comes to add-ins, so stick to the suggested quantities and adjust slightly to your taste.

Variations & Adaptations

One of the best things about this Everything Bagel Breakfast Casserole recipe is how easy it is to customize. Here are a few ideas to make it your own:

• Vegetarian Version: Skip the meat and add extra veggies like mushrooms, cherry tomatoes, or broccoli. You can also use vegetarian sausage crumbles.
• Lower-Carb Option: Replace the bagels with cubed cauliflower or broccoli for a lighter, keto-friendly version.
• Seasonal Twist: Swap the veggies for seasonal favorites like asparagus in spring or roasted sweet potatoes in the fall.
• Spicy Kick: Add diced jalapeños or a splash of hot sauce to the egg mixture for some heat.
• Cheese Swap: Use pepper jack for extra spice or goat cheese for a tangy flavor.

One of my favorite personal variations is adding a layer of caramelized onions and sautéed mushrooms for an earthy, slightly sweet touch. It pairs beautifully with the savory bagel seasoning!

Serving & Storage Suggestions

This Everything Bagel Breakfast Casserole is best served warm, straight from the oven. The cheese will be melted and gooey, and the bagels will have a mix of soft and crispy textures.

• Serving Suggestions: Pair this casserole with a fresh fruit salad, orange juice, or a hot cup of coffee for a complete breakfast or brunch spread.
• Storing Leftovers: Cover the dish tightly and store it in the refrigerator for up to 3 days.
• Reheating Tips: Reheat individual portions in the microwave for 1-2 minutes, or warm the entire casserole in a 350°F (175°C) oven for 10-15 minutes.
• Freezing Option: You can freeze the casserole before baking—just wrap it tightly and store for up to 2 months. When ready to bake, thaw overnight in the fridge and cook as directed.

Pro Tip: This casserole tastes even better the next day as the flavors meld together. It’s perfect for leftovers!
