  • 1 oz. 30 g (60 ml) shredded cheese

  • 4 4 large mushrooms, sliced

  2. Melt the butter in a frying pan, over medium heat. Add the mushrooms and onion to the pan, stirring until tender, and then pour in the egg mixture, surrounding the veggies.

    I'm trying to figure how to convert the percentages to grams since I was suggested to have at least 94 grams of protein because of my height which is 5'4 and 20 grams or less on carbs. I used the converter. i.e. - 2 percent equals 20 grams but your recipe said 2g. I wanted to know how did you get that number? 23 percent in protein equals 230 grams. it is too much than 94. Help me here please!!

    Hi Laureen!

    One serving is 2 g carbs (equal 2% of the total Energy)
    Protein content is 23% of the total Energy

    That means the protein content is 23% / 2% * 2g = 23 g protein per serving

    I agree that it would be a lot easier if the recipe simply listed the grams of fat, carbs, protein, etc. I didn't find the protein details hiding behind the icon, until I read Laureen's comment and went back looking for it.

    I have the hardest time making omelettes, even on a low heat they either burn or just won't cook, there's nothing quite as nasty as an undercooked omelet! I assume others have a higher success rate than I. ..any tips?
  16. Alison Craddock
    Don't cook omelettes on a low heat. The trick is to heat your pan with a little oil or butter until quite hot, then pour your eggs in quickly and slip it all over your pan. The hot oil will seal your eggs and stop them sticking. Add your filling after your eggs have sealed.
  17. Brenda Perkins
    Classico has a great tomato basil sauce that's low in carbs.
  18. Eddie Carlin
    Glad my doctor recommended low-carb. I have lost over 60 lbs in about 5 months.

    Is the mushroom cooked enough to eat? As per recipe, it seems that mushroom is wrapped inside the omelette, and is not cooked directly at all. Moreover, it would taste raw, I am guessing.

    How is the taste of mushrooms?

  20. Mary
    I cooked the onion and mushroom in the butter first then added it to the omelette with the cheese. There was still enough butter in the pan for the omelette and it was delicious.
  21. Els
    I was wandering the same, Nayan, about adding the mushrooms raw. I will make this, but cook onion and (oyster!) mushrooms first. Great advice, Mary!
  22. Maureen Kutcher
    How can this diet work for someone who is a type 1 diabetic and a celiac. On a low calcium diet due to kidney problems?
  23. Cristi S
    I have some doubts about this recipe... Onions and mushrooms take more to get the heat. If you add them on top when we're told, we get them under-cooked, far from what we see in that picture. Or we cook the eggs too much. Also, I used to add the cheese to the eggs mix, because the whole stuff will be more fluffy.

    This being said, I continue to follow this diet with the amazing recipes from this site. But I'm a bit disappointed: Gordon Ramsey said first proof you know to cook is to show how to make a good omelet. The picture above was amazing, but the instructions were wrong.

    I did low carb but went over to kepo. I am busy now for 2 weeks. Helas, my weight seems to stay the same or even a bit more. What to do?
    Thanks in advance, Simone Schell

    I m curious as to find out where the nutrition facts are for these meals? I'm only seeing how many net carbs are in one serving. I need to know fat and protein as well.

    omelette personally was awful as not only was it swimming in way too much fat but the fact that the mushrooms and onions are put in right at the end leaves them raw. Better off cooking veggies before as you would in a normal omelette and cutting down on the butter.

    What does it mean by 4g. 4 grams of fat? It says this by the pic.

    Hi Ali!

    It means 4 gram carbs in one serving.

    I cooked the onion first in a non-stick pan, then melted ghee and poured the mixture, then added mushrooms. Turned out good, though I don't know how you got that brown sauce in the picture.
  32. Pete
    I agree with you. I think the onions and mushrooms need to be cooked before, probably for about 5 minutes on a medium-high heat, then added to the omelette afterward. No one wants raw mushrooms or onions in their omelette.
  33. Sharona
    Hi. I saw that carrot is under ground veggi.. together with potato. Maybe that’s why.
  34. Rc
    Try the nutritional fact finder or calorie counter
  35. sarah
    That picture does not match the recipe. There are like 20 mushrooms in there and they're pre-cooked before adding to the omelet. How about some truth in advertising? ;)
  36. Jessica Davis
    No you can not eat carrots on Keto also if you download MyFitnessPal it will help you with the calories and the amount of fat that you will be eating as well

    Most people on keto find they have the most success at about 5% carbs, 20-25% protein and 70-75% fats.

    Is it okay if I swap the cheese for bacon?

    They will bring very different properties to the final omelet. You can definitely add bacon!

    Different people lose weight at different rates but most people see results within the first week or two.

    Just had this for breakfast and it's yummy! I sliced up a spring onion instead of the 1/4 yellow onion and 125g sliced chestnut mushrooms and it worked perfectly. I'm comfortably stuffed now! :)

    I have been eating once a day and honestly, it works.
