Microwave Egg Sandwich with Cheddar and Avocado

This microwave egg sandwich with cheddar and avocado is the ultimate solution for a quick and nutritious vegetarian breakfast. By using a microwave-safe bowl roughly the same size as your bread, you create a perfectly shaped, fluffy egg patty that rivals any high-street coffee shop muffin. The addition of sharp cheddar and creamy avocado provides a wonderful contrast in textures, while a splash of water ensures the eggs remain light rather than rubbery.

Ideal for busy weekdays or student kitchens, this recipe is incredibly versatile and can be assembled in less than five minutes. Whether you choose a classic English muffin or thick-cut sourdough toast, the combination of melted cheese and fresh avocado makes for a satisfying, protein-rich start to the day. For an extra kick of flavour, try experimenting with different shop-bought pestos or your favourite hot sauce.

Ingredients for Microwave Egg Sandwich with Cheddar and Avocado

  • Nonstick vegetable oil spray, vegetable oil, or unsalted butter

  • 2 large eggs

  • 1/8 teaspoons kosher salt

  • Pinch of fresh ground black pepper

  • 2 tablespoons grated cheddar

  • 2 slices toast or 1 English muffin, biscuit, or roll, split, toasted

  • 1/4 avocado, sliced

  • Hot sauce or pesto (for serving)

  • A microwave-safe, flat-bottomed bowl or cup roughly the size of your sandwich.

Spray inside of bowl with nonstick spray or lightly coat with oil or butter. Add eggs, salt, pepper, and 1 tablespoon water; mix with a fork until combined.

Microwave on high 30 seconds; you should see bits of solid egg floating in uncooked part. Stir gently (this will help egg cook evenly) and microwave again 30 seconds or until egg puffs up dramatically. Add cheese and continue to microwave until egg is just set and cheese is melted, 15–30 seconds. Using a small spatula, transfer egg mixture to bottom toast slice. Top with avocado, drizzle with hot sauce or pesto, then top with remaining toast slice. Serve immediately.
