Why This Recipe Works

  • A breakfast sandwich is easy to customize. Although I love our version of a breakfast sandwich, the real possibilities are endless! Are you an English muffin lover? A bagel diehard? Use the bread you love - plus, feel free to add whatever you're craving, you can fill your sandwich with a virtually unlimited assortment of ingredients.
  • It's a great way to start the day. When you start your day with a breakfast sandwich that looks and tastes as good as this one, you know it's going to be a great day. Filled with protein and vegetables, it'll keep you full till lunch.
  • Recipe doubles (or triples!) well. If you'd like to make a second sandwich, just double the ingredient amounts.
  • This a quick and easy recipe. A breakfast sandwich can be ready in just 10 minutes!

Ingredient Notes

See below for ways to use leftover ingredients.

  • Eggs: I use 2 large eggs.
  • Butter: Butter is used to grease the skillet to cook the eggs.
  • Spinach: About ½ cup of fresh spinach is the perfect amount for this sandwich. Feel free to use arugula instead.
  • Tomatoes: I use 1 Roma or Plum tomato. This variety is a perfect size but use the type of tomato you have on hand.
  • Avocado: Use 1 small avocado or ½ of a medium avocado.
  • Cheese: I love using Fontina cheese with eggs. This cheese is incredibly rich and creamy with a buttery, slightly nutty taste. You can use the type of cheese you have on hand or use the kind you love.
  • Salt and black pepper: These two ingredients add flavor.
  • Bread: I use a brioche bun for our breakfast sandwich. Instead, consider using a croissant or thick slices of sourdough bread.

How To Make A Breakfast 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.

Frequently Asked Questions

Can I Freeze This Breakfast Sandwich?

This is more of a fresh breakfast sandwich that is best enjoyed shortly after making it.

Can I Double This Recipe?

Yes! If you'd like to make a second sandwich, just double the ingredient amounts.

Is This A Vegetarian Breakfast Sandwich?

It sure is and it's so tasty, you absolutely won't miss the meat! If you'd like to make a non-vegetarian version, go ahead and add a slice or two of crispy bacon or ham.

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.
  • Proteins: Bacon, ham, sausage, turkey, pulled pork, chorizo, smoked salmon, eggs.
  • 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.

Serving Suggestions

Serve this egg and avocado breakfast sandwich alone or with a simple arugula or a mixed greens salad with vinaigrette. I also love adding a bowl of fruit, a glass of juice and/or a mimosa.
