Peel the 3 potatoes and cut them into chunks, about 3 cm, so they cook fast and evenly.
Get the potatoes going
Put the chunks in the saucepan, cover with cold salted water and bring to a boil. Let them simmer until a knife slides in with no resistance.
Prep the mushrooms, garlic and parsley
Wipe the mushrooms with a damp dish towel and slice them. Crush or mince the garlic and chop the parsley.
Sauté the mushrooms
Melt half of the butter (10 g) in the skillet over high heat and brown the mushrooms 5 minutes without stirring too much, then add the garlic for the last minute. Salt, pepper, then take them out of the skillet and set them aside on a plate.
Tip · Don't stir the mushrooms for the first few minutes and only salt them at the end, or they release their water and boil instead of browning.
Beat the eggs
Crack the 4 eggs into a bowl, add a pinch of salt and pepper and half of the parsley. Beat with a fork without making it too foamy.
Mash the potatoes
Drain the potatoes and put them back in the saucepan. Mash them with the crème fraîche, salt, pepper and keep warm under a lid or a plate.
Cook the soft omelet
Wipe out the skillet, melt the rest of the butter (10 g) over medium heat and pour in the eggs. Stir 30 seconds with the spatula, then let it set over low heat until the edges are set and the center is still creamy.
Tip · Pull the skillet off the heat while the center is still a bit glossy, the omelet finishes cooking from its own heat and stays soft.
Fill, fold and serve
Spread the mushrooms you set aside over one half of the omelet and fold the other half over. Cut in half, plate with the mashed potatoes and sprinkle with the rest of the parsley.

Pantry salt, oil and spices aren't counted. Your store and your brands will move the total, but the ballpark is right.
How long does it keep?
Eat it fresh. An omelet is best soft, fresh out of the pan: reheated, it turns rubbery. Make it the day you eat it, it's done in 5 minutes!
