Then cut into cubes or strips.Vegetables: Cut the onions into fine cubes, finely chop the garlic and cut the mushrooms and peppers into slices.Cook pasta: Bring a pot of water to the boil and add 1 tablespoon of salt. Add the egg noodles to the boiling water and cook until al dente. After cooking, drain and rinse briefly with cold water to prevent sticking. Keep warm.Fry beef fillet: Heat the vegetable oil and 1 tablespoon of butter in a pan. Add the beef fillet cubes or strips to the pan in portions (not all at once) and fry until lightly browned on all sides (approx. 2-3 minutes). Remove the fried cubes or strips from the pan and put them aside on a plate. Make sure not to fry the cubes or strips for too long, otherwise they will become tough.Fry vegetables: Sauté the onions until translucent. Add the garlic and sauté briefly. Add the mushrooms and peppers and sauté until well browned and soft.Prepare the sauce: Sprinkle the flour evenly over the vegetables and stir well to combine. This helps to bind the sauce. Stir in the paprika, mustard and ketchup and fry briefly. Slowly add the beef stock or demi glace and red wine, stirring constantly to avoid lumps. Mix everything well and bring to the boil. Reduce the heat and stir in the crème fraîche (sour cream) and whipped cream. Now add the pickled gherkins cut into strips. Simmer the sauce for about 5-10 minutes until it has thickened slightly. Season with salt and pepper to taste.Add the beef fillet back: Put the seared beef fillet strips back into the pan and heat briefly so that they remain tender. The sauce should now be nice and creamy.Serving: Divide the pasta between plates and generously arrange the beef stroganoff next to it.Garnish with freshly chopped parsley or chives.
