Nessy's Note

While I love creating and sharing breakfast recipes (like sweet potato avo toast) with you, my weekday breakfasts don't always look pretty enough to photograph...

One of my absolute favorite, pull-it-together, simple breakfasts is just poached eggs with diced avocado, some s+p and whatever leftover veggies we have in the fridge. It hits the spot and fuels me for hours.

And it's the inspiration for this (slightly more photogenic) omelet. It has the same satisfying combo of avocado and eggs along with the addition of cheese (because what does cheese not make taste better?) and onions.

But if you'd rather skip the whole omelet thing on a busy morning and just have eggs and avocado, you're in good company 😉.

Ingredients and Substitutions

Ingredients measured out on a plate.
  • Eggs- Like in my salsa scrambled eggs, I use 3 whole eggs to make for a filling breakfast. You can swap 1 egg for ¼ cup egg whites if you prefer.
  • Butter- Helps to prevent the omelet from sticking and is used to cook the onions.
    • Substitution: You could use olive oil or avocado oil if you prefer.
  • Onions- I used a white onion as it is what I most often have on hand.
    • Substitution: Any color of onion you like would work or leave them out.
  • Fine Sea Salt- Kosher salt or table salt also work.
  • Avocado- Look for a ripe avocado that has brown skin and gives a little when you squeeze it but isn't squishy. (The same kind of avocado that makes for good hot honey avocado toast).
  • Cheddar cheese- Shred your own as it melts so much better than the pre-shredded stuff. You can also just thinly slice a bit of cheese and lay it across the eggs to melt (that's what I did for this California omelet).
    • Substitution: Monterey Jack, Mozzarella or Pepper Jack are all great too.

Tips for A Tasty Avocado Omelet

  • Cook low, slow and covered. Using medium-low heat and covering the pan cooks the eggs evenly without needing to flip the omelet.
  • Use a non-stick or low-stick skillet. Use a non-toxic non-stick, well-seasoned cast iron or properly preheated stainless steel pan to ensure your omelet doesn't stick.
  • Prep the filling in advance. If you’re short on time in the morning, cook a batch of onions in advance. Then in the morning, simply whisk them into the eggs and cook.

Notes

Leftovers: This omelet is best enjoyed fresh, but if you do have leftovers, store in the refrigerator for up to two days. Reheat in the microwave or gently in a skillet. Ideally, store the avocado separately and add it after reheating.
Make Ahead: For easier mornings, you can prep the sautéed onions ahead of time and store them in an airtight container (up to 3 days ahead).
