Ingredients Equipment Method Notes

Ingredients
  

  • 1 slice Sourdough Bread About 1-inch thick
  • 0.5 Large Hass Avocado Ripe but firm
  • 1 Large Egg Free-range preferred
  • 1 tsp Lime or Lemon Juice Freshly squeezed
  • 1 tsp Olive Oil or Butter
  • Flaky Sea Salt To taste
  • Freshly Cracked Black Pepper To taste
  • Red Pepper Flakes Optional, to taste

Equipment

  • 1 Skillet A non-stick skillet is recommended for the egg.
  • 1 Toaster Optional, can also toast in the skillet.

Method
 

  1. Drizzle or brush your slice of sourdough with a little olive oil or spread a thin layer of butter on it. Toast it in a skillet over medium heat, in a toaster, or under a broiler until it's golden brown and crisp on both sides.
  2. While the bread is toasting, scoop the flesh of your avocado half into a bowl. Add the fresh lime or lemon juice, a pinch of salt, and pepper. Gently mash with a fork, leaving some chunks for texture.
  3. In a non-stick skillet, heat the remaining olive oil or butter over medium-low heat. Crack the egg into the pan and cook for 2-3 minutes, or until the whites are set but the yolk is still runny.
  4. Spread the mashed avocado evenly over your warm sourdough toast, right to the edges. Gently slide the fried egg on top of the avocado.
  5. Finish with a sprinkle of flaky sea salt, more black pepper, and a pinch of red pepper flakes if you like a little heat. Serve immediately.

Notes

For a perfect runny yolk, avoid high heat when cooking the egg; medium-low is best.
To easily check avocado ripeness, flick the small stem cap at the top. If it comes off easily and you see green underneath, it’s ready to use.
