Bagel Casserole Ingredients
For the Casserole
• Bagels – Choose fresh, frozen, or stale bagels; stale bagels work best for a non-soggy texture.

• Onion – Sautés beautifully, adding depth of flavor; shallots can be substituted for a milder taste.
• Spinach – Offers a nutritious boost and earthy freshness; fresh or frozen works wonders.
• Diced Tomatoes – Brings moisture and a touch of acidity; canned tomatoes are a convenient option.
• Cheeses (cream cheese and shredded cheese) – Introduces creaminess and flavor; ricotta can replace cream cheese for a different texture.
• Eggs – Acts as the binder; egg substitutes like flax eggs can work if needed.

How to Make Bagel Casserole
-
Prep Bagels: Cut your bagels into bite-sized pieces and spread them evenly in a greased casserole dish. This will serve as a beautiful base that absorbs all the delicious flavors.
-
Cook Bacon: In a large skillet, cook the bacon over medium heat until it’s crispy. Remove it from the pan, drain on paper towels, and crumble it up to sprinkle over the layers later.
-
Sauté Vegetables: Using the bacon fat in the skillet, sauté diced onion and spinach until the onions are translucent and the spinach is wilted—around 3-4 minutes. This adds an incredible depth of flavor!
-
Layer Ingredients: Scatter the sautéed vegetables, crumbled bacon, and diced tomatoes over the bagel pieces in the dish, ensuring an even distribution of flavors.
-
Prepare Egg Mixture: In a large bowl, whisk together the eggs, milk, and your Everything Bagel Seasoning until smooth and well combined—smoothness is key for a cohesive texture!
-
Combine & Pour: Gently pour the egg mixture over the layered ingredients, allowing it to seep through. For extra creaminess, add chunks of cream cheese throughout the layers.
-
Bake: Cover the dish with foil and bake in a preheated oven at 350°F (175°C) for 45-55 minutes. It’s done when it’s set in the center and slightly golden on top.
-
Cool & Serve: Once baked, allow the casserole to cool for a few minutes before slicing. This helps it hold its shape and makes serving easier!
Optional: Top with fresh herbs before serving for an extra touch of freshness.

Bagel Casserole Recipe FAQs
What type of bagels should I use?
Absolutely! Stale bagels work best for this casserole as they absorb the egg mixture without becoming soggy. If you only have fresh or frozen bagels, don’t worry—just give them a light toast to dry them out a bit before using.
How should I store leftover Bagel Casserole?
To keep your casserole fresh, store leftovers in an airtight container in the fridge for up to 3 days. You can enjoy it heated for quick breakfasts or snacking throughout the week!
Can I freeze the Bagel Casserole?
Yes, you can! Wrap the entire casserole tightly in plastic wrap and then in foil for maximum freshness. It can be frozen for up to 2 months. When ready to enjoy, simply thaw overnight in the fridge and reheat.
What if I don’t have all the ingredients?
Very! This recipe is incredibly flexible. You can substitute the crispy bacon with cooked sausage, turkey bacon, or even a plant-based alternative. Additionally, feel free to replace the spinach with kale or Swiss chard to change flavors and add variety!
Why is my casserole soggy?
If your casserole turns out soggy, it’s likely due to using fresh bagels without toasting them first. Stale bagels are ideal as they provide a firmer texture. You can also try reducing the amount of liquid (milk and eggs) if you’re using particularly moist vegetables.
Can my pet eat the casserole leftovers?
While it might be tempting, it’s best to avoid sharing this casserole with pets. Some ingredients, like onions, can be harmful to dogs and cats if consumed in significant amounts. Always check which ingredients are safe before giving any human food to your pets.
