01 - In a mixing bowl, combine the flour, eggs, milk, chopped herbs, salt, and nutmeg. Mix until a smooth batter forms. Let it rest for 10 minutes.
02 - Bring a large pot of salted water to a boil. Using a spaetzle maker or a colander, drop the batter into the boiling water in small portions. Cook until the spaetzle float to the surface, about 2-3 minutes. Remove with a slotted spoon and set aside.
03 - In a large skillet, heat olive oil and butter over medium heat. Add the chopped onion and garlic, sautéing until softened.
04 - Add the sliced mushrooms and cook until browned. Pour in the heavy cream and simmer for 5 minutes, allowing it to thicken. Season with salt and pepper.
05 - Stir the cooked spaetzle into the mushroom cream sauce, mixing well to coat. Serve hot, garnished with fresh parsley.
