Avocado Egg Sandwich with Everything Bagel

 Avocado egg sandwich with everything bagel - a hearty, flavorful breakfast with fried egg, creamy avocado, and melty Swiss cheese.

This avocado egg sandwich on a toasty everything bagel is a hearty, flavorful breakfast that’s both satisfying and simple to make. I first started making this for my husband so he’d have something filling to keep him going until lunch, and it quickly became a favorite in our home. With a fried egg, creamy avocado, and melty Swiss cheese, it’s the perfect grab-and-go option for busy mornings or a cozy weekend treat.

Ingredients You Need

• Bagel – Any savory bagel works well. My favorites are everything, onion, and sesame.
• Avocado – Slice or mash it. I mash mine so it doesn’t slide out when I take a bite.
• Everything Bagel Seasoning – I use Trader Joe’s, but you can find other brands online or at most grocery stores.
• Fried Egg – For sandwiches, I like my eggs cooked over hard so they’re less messy. If you prefer a runny yolk, that works too — just grab a fork and knife.
• Swiss Cheese – Mild, slightly sweet, and nutty. It pairs perfectly with avocado and egg, but feel free to swap in your favorite cheese (see substitutions below).

Substitutions for the Sandwich

• Bread – Swap the bagel for sandwich bread, sourdough, or even a baguette. Sourdough works well as an open-face sandwich, and a hearty baguette holds everything in nicely.
• Protein – I use fried egg here, but you can add deli meat, breakfast sausage, or plant-based sausage for extra protein.
• Cheese – Swiss is my go-to, but cheddar, mozzarella, or Colby Jack are all delicious options.

How to Make an Avocado Egg Sandwich

1. Toast the bagel: Slice your bagel in half and toast it to your liking.
2. Cook the eggs: While the bagel is toasting, fry two eggs in a skillet. Season with salt and pepper. For a little heat, add a pinch of red pepper flakes.
3. Add the cheese: When the eggs are almost done, place a slice of cheese on top. Turn off the heat and let it melt slightly.
4. Prepare the avocado: Spread mashed avocado on one half of the toasted bagel. (I mash mine so it stays in place when biting into the sandwich.)
5. Add seasoning: Sprinkle everything bagel seasoning over the avocado.
6. Assemble: Place the cooked egg and melted cheese on top of the avocado. Add the other half of the bagel.
7. Serve: Enjoy right away while warm.

Helpful Tips on Avocado Fried Egg Bagel Sandwich

• Avocado options – Smash it directly onto the toasted bagel, make a chunky guacamole, or use slices. (Just note that slices tend to slide out when you bite into the sandwich.)
• Melty cheese trick – Place the cheese on top of the egg right after flipping it to cook the other side. This gives it time to get warm, gooey, and perfectly melted.
• Egg variations – If you’re not in the mood for fried eggs, scramble them instead. You can stir your cheese right into the scrambled eggs for a different texture.
• Make-ahead option – Toast the bagel and cook the egg and cheese ahead of time. Store them separately in the fridge, then reheat and assemble with fresh avocado just before serving.

This avocado fried egg bagel sandwich is one of my favorite ways to start the day - hearty, flavorful, and easy to customize. Whether you enjoy it on a busy weekday or a slow weekend morning, this avocado egg sandwich on an everything bagel is sure to keep you satisfied until lunch.
