Everything Bagel Breakfast Casserole Recipe

Everything bagels: These bagels are seasoned with a mix of sesame seeds, poppy seeds, garlic, onion, and salt, adding a burst of flavor to the casserole.

Eggs: Provide structure and richness to the dish, binding all the ingredients together.

Milk: Adds moisture and helps create a creamy texture in the casserole.

Shredded cheddar cheese: Melts beautifully, adding a sharp, tangy flavor to the dish.

Chopped cooked bacon: Adds a smoky, savory element that complements the other ingredients.

Chopped green onions: Provide a fresh, mild onion flavor and a pop of color.

To ensure your everything bagel breakfast casserole has a perfectly creamy texture, let the bagel pieces soak in the egg mixture for about 10-15 minutes before baking. This allows the bagels to absorb the eggs and milk, resulting in a more cohesive and flavorful dish.

• Allow the casserole to cool completely before storing. This helps prevent condensation, which can make the dish soggy.
• Cover the baking dish tightly with aluminum foil or plastic wrap. Alternatively, transfer the casserole to an airtight container.
• Store in the refrigerator for up to 3-4 days. Reheat individual portions in the microwave or the entire dish in the oven at 350°F (175°C) until warmed through.
• For freezing, cut the cooled casserole into individual portions. Wrap each portion tightly in plastic wrap, then place them in a freezer-safe bag or container.
• Label the container with the date and contents to keep track of freshness.
• Freeze for up to 2-3 months. When ready to eat, thaw the portions overnight in the refrigerator.
• Reheat thawed portions in the microwave or oven. If using the oven, cover with foil and bake at 350°F (175°C) until heated through, about 20-30 minutes.
• To maintain the best texture, avoid freezing the casserole with the green onions on top. Instead, add fresh green onions after reheating.

• Preheat your oven to 350°F (175°C). Place the leftover everything bagel breakfast casserole in an oven-safe dish. Cover it with aluminum foil to prevent it from drying out. Bake for 20-25 minutes, or until heated through. Remove the foil for the last 5 minutes to allow the cheese to get bubbly and slightly crispy.

• If you prefer using a microwave, transfer a portion of the casserole to a microwave-safe plate. Cover it with a microwave-safe lid or a damp paper towel to retain moisture. Heat on medium power for 2-3 minutes, checking halfway through to ensure even heating. Let it sit for a minute before enjoying.

• For a quick stovetop method, cut the casserole into smaller pieces. Heat a non-stick skillet over medium heat and add a small amount of olive oil or butter. Place the pieces in the skillet, cover with a lid, and cook for 5-7 minutes, flipping halfway through, until heated thoroughly and slightly crispy on the edges.

• If you have an air fryer, preheat it to 350°F (175°C). Place the casserole pieces in the air fryer basket in a single layer. Heat for 5-7 minutes, shaking the basket halfway through to ensure even heating. This method will give you a crispy exterior while keeping the inside moist.

• For those who enjoy a bit of steam, use a steamer basket. Place the casserole pieces in the basket over simmering water. Cover and steam for 10-12 minutes, or until heated through. This method helps retain moisture and keeps the eggs fluffy.

• If you have a toaster oven, preheat it to 350°F (175°C). Place the casserole on a baking sheet and cover with foil. Heat for 15-20 minutes, removing the foil for the last 5 minutes to crisp up the cheese and bagels.
