A breakfast sandwich typically includes bread, eggs, and cheese, often with added ingredients like vegetables or meats. Our version features spinach, tomato, eggs, cheese, and avocado. This combination results in a balanced meal that’s high in protein and healthy fats. The ingredients are sandwiched between bread or a bun, creating a convenient and delicious meal that’s easy to eat on the go.

If you have any ingredients leftover from this easy breakfast sandwich recipe, check out our Leftover Ingredients Recipe Finder.

  • Eggs: Use two large eggs for the sandwich.
  • Butter: Grease the skillet with butter before cooking the eggs to prevent sticking and add flavor.
  • Spinach: Measure approximately 1/2 cup of fresh spinach to add to the sandwich. If preferred, you can substitute spinach with arugula. Got extra spinach? Use some in a Frittata, Green Smoothie, or Turkey Wrap.
  • Tomatoes: One Roma or Plum tomato is ideal due to its size and juiciness, but feel free to use whatever type of tomato you have available. Extra tomatoes can be used in Caprese Pasta or a Taco Salad.
  • Avocado: If using a small avocado, use the whole thing. If it’s a medium avocado, just use half. Leftover avocado can be used to make Avocado Toast or Guacamole.
  • Cheese: Fontina cheese is recommended for its creamy texture and rich, nutty flavor. However, any preferred cheese, including vegan cheese options, can be substituted.
  • Salt and black pepper: A pinch of both salt and black pepper will enhance the overall flavor of the sandwich.
  • Bread: A brioche bun is suggested for its softness and slight sweetness. Alternatives include a croissant or thick slices of sourdough bread. For those on a gluten-free diet, look for gluten-free bread.

Breakfast Sandwich Variations

Although I love this egg and avocado breakfast sandwich just as it is, you might like to create your own breakfast sandwich by picking a few items from the categories below:

  • Breads: English muffin, bagel, toast, pita, naan, biscuit, bun, tortilla, or croissant.

  • Cheeses: Cheddar, swiss, provolone, brie, muenster, mozzarella, smoked gouda, American, cream cheese, pimento cheese, feta or fontina.
  • Greens: Spinach, swiss chard, arugula, watercress, or butter lettuce.
  • Toppings: Tomatoes, avocados, caramelized onions, pickled onions, salsa, sliced apples, pico de gallo, or roasted red peppers.

How To Make A Breakfast Sandwich

These step-by-step photos and instructions help you visualize how to make one egg sandwich. See the recipe box below for ingredient amounts and full recipe instructions.

  1. Cook the eggs: Melt the butter in a small skillet over medium heat. While the butter is melting, crack two eggs in a small bowl and beat them with ⅛ of a teaspoon of salt and ⅛ of a teaspoon of black pepper.

  1. Pour the eggs into the pan and cook, stirring continuously with a rubber spatula, making sure to scrape the bottom of the pan. Transfer the cooked eggs to a bowl.

Pro Tip: To cook perfect scrambled eggs, cook the eggs as you would cook a risotto, don’t stop stirring. As you move the eggs around, you can see them setting around the base and notice little cooked curds and raw eggs. Continue stirring until the eggs fully come together as shown in the photos below.

  1. Assemble the sandwich: Toast the brioche bun in a 350°F (177°C) oven or in a toaster oven if your bun fits.
  2. When the bread has toasted, place 1 or 2 slices of cheese on one half of the bun and top with the scrambled eggs, spinach, and tomato slices. Mash the avocado and spread it over the other half of the bun.

Pro Tip: To mash an avocado with a fork, cut an avocado in half lengthwise. Twist to separate the two halves. With a sharp knife, stick the seed with the blade and lift out the seed. Scoop the meat from the skin of one-half of the avocado with a tablespoon and place it on a plate. Mash with a fork.

  1. Cut in half and enjoy!

Expert Tips

  • Read through the entire recipe before beginning. This easy breakfast sandwich recipe comes together quickly. Be sure to read through the recipe, review the ingredient notes, and gather your ingredients before starting.
  • Pay attention to the layers. Placing the cheese on the bun and then adding the warm eggs helps to melt the cheese which helps the eggs stay put. The mashed avocado also helps hold the tomatoes in place.
  • To slice the sandwich perfectly, tightly wrap the finished sandwich in butcher paper and slice it in half with a serrated knife.
  • For a buttery crunch, pan-fry both halves of the bread with some butter instead of toasting it.

Serving Suggestions

  • Simple side: Arugula salad or mixed greens salad with a vinaigrette dressing.
  • Fruity addition: A bowl of your favorite fruit.
  • Drink options: A glass of fresh juice or a celebratory mimosa.
