How to Make Everything Bagel Breakfast Casserole

Prepare a 9×13 casserole dish with nonstick cooking spray. 

In a large (12-inch) skillet over medium-high heat, cook the sausage, crumbling as it cooks. When the sausage is almost completely browned, add the bell pepper and the onion, cooking together until the sausage is done. Drain well and stir in the spinach.

Tips and Tricks

Here are some tips and tricks to ensure your Everything Bagel Breakfast Casserole turns out perfectly:

  1. Stale Bagels Rule: For the best texture, use slightly stale or day-old bagels. They’ll absorb the egg mixture without becoming too soggy.
  2. Prep Ahead for Ease: Prepare the casserole the night before and let it chill in the fridge. This allows the flavors to meld and makes for an effortless morning bake.
  3. Bagel Size Matters: Cut the bagels into bite-sized pieces for even distribution of flavors and easier serving portions.
  4. Let it Soak: Give the bagel pieces a few minutes to soak up the egg mixture before transferring to the baking dish. This helps ensure a consistent texture throughout.
  5. Layer for Flavor: Layer the bagel pieces, cheese, and any additional ingredients like veggies or meats for a well-balanced casserole with each bite.
  6. Cover and Uncover Technique: Cover the casserole with foil for the first half of baking to prevent excessive browning. Uncover it for the last portion of baking to achieve a golden-brown crust.
  7. Check for Doneness: To ensure it’s fully cooked, insert a knife or toothpick into the center. If it comes out clean without any raw egg mixture, it’s ready.
  8. Rest before Serving: Allow the casserole to rest for a few minutes before cutting into it. This helps it set and makes for easier serving.
  9. Garnish for Appeal: Sprinkle extra everything bagel seasoning, fresh herbs, or a drizzle of hot sauce over the top before serving to enhance both flavor and presentation.
  10. Storage Savvy: Store leftovers in an airtight container in the refrigerator for up to a few days. Reheat slices in the oven or microwave for a quick and delicious breakfast throughout the week.
