How to Make This Mushroom Swiss Omelette
You only need a few simple ingredients and these step-by-step instructions to make this low carb, high protein breakfast recipe.
- In a 6 inch skillet melt 1/2 tablespoon of butter over medium heat, sauté the mushrooms and garlic, stirring occasionally, until the mushrroms are tender, about 6 minutes. Remove the mushrooms from the pan and set aside.
- In a small bowl beat the eggs, heavy cream, salt and pepper until the eggs and smooth and a little frothy.
- Wipe the pan clean with a paper towel and melt the remaining butter, tilt the pan back and forth so the bottom and sides of the pan are greased.
- Pour the beaten eggs into the pan, tilt the pan back and forth so it is evenly coated. If the eggs seem to be cooking too quickly reduce the heat to medium low. Allow the eggs to cook undisturbed until the eggs have almost set.
- Top half of the omelette with the Swiss cheese and sautéed mushrooms, fold the other half of the egg over the fillings.
How to Customize Your Omelet

- Bacon, Cheddar and Green Onions
- Ham, Swiss and Sautéed Onions
- Sausage, Colby Jack, and Sliced Peppers
Tips and Tricks
- Use a small skillet for a two egg omelet. This results in the perfect thickness; if you use a large pan the omelette will be very thin and difficult to flip.
- Opt for a silicone spatula over a metal spatula.
- Beat the eggs well before adding to the pan, whisking the eggs makes the omelette perfectly light and fluffy.
- Season the eggs before you whisk them.
- Use a good heavy bottom, nonstick pan.
