Caramelized Onions and Mushroom Omelette Sandwich

omelette sandwich

I wasn’t going to create a post for this but someone asked for it in my Instagram. It’s way too cold here – 4 degrees C this morning to be precise (brr!). Spending time in the kitchen is something I keep to a minimum during nights. When I do cook, I up the quantity so I have leftovers for the next dinner. There was leftover Thai veg curry for him and I made myself a quick omelette sandwich. Simply caramelize onion slices till they are nice and golden brown. Cook the mushrooms in it and then go in the eggs. Sandwiched between two buttered bread slices and lettuce (if you have any), and pan toasted to get that perfect tan on both sides. A dinner sandwich is ready.

If you’re new to the kitchen or if you think it takes too much effort and time to whip up a satisfying dinner, you’re wrong. This sandwich says so, not me. Once you make this sandwich you’ll make variations of this and won’t be afraid to try new dishes.


2 sandwiches

Prep time:

5 mins

Cooking time:

7-8 mins


Eggs – 3

Onions – 1 medium sliced

Mushrooms – 1 cup slices

Chilli powder/pepper powder/any seasoning mix powder like leftover sachets of pizza oregano  Р1 tsp

Salt to taste

Oil – 2 tsp

Bread – 4 slices

Butter – 1 tsp per slice

Lettuce – couple of leaves (don’t worry if you don’t have any, just use a cheese slice instead!)


Heat oil in a nonstick pan and saute the onions in it. Let the flame be on high.

In about 3 mins the onions should have turned slightly darker in colour.

Now add the mushrooms and mix well. Leave it to cook while you get on with the eggs.

Crack the eggs into a clean dry bowl and whisk with a fork for about a minute.

Now pour on the onions and mushrooms. Sprinkle salt (about two pinches should do) and the other seasonings.

Lower the flame and cover. Let this cook for about 2 mins.

Take the lid off and try to flip the omelette over to the other side. If you can’t, just run your¬†spatula in the middle to cut it into you and individually flip it. You might not have a perfectly round omelette in the end but no one’s going to judge, I promise.

Let it cook on the other side for 30-40 seconds, and you’re done.

Tear a piece of omelette and place it on a bread slice.

Dab some ketchup and mustard on this – this step is purely optional. I didn’t add any.

If you have lettuce it goes on top of the omelette. If you don’t have lettuce, use any other greens or maybe a cheese slice.

Another bread slice on top.

In the same pan add 1 tsp of butter and once it melts place the sandwich.

In about 30-40 secs it will brown. Carefully turn it over and let the other side brown.

Sandwich is ready. Dig in!
