Let the oil get hot in a pan. In the meantime, season the turkey schnitzel with salt and pepper. Then fry the seasoned turkey schnitzel in hot fat on both sides for about 8-10 minutes.
Then remove the schnitzel and keep warm.
Melt the butter in the remaining roast fat. Stir in the flour and deglaze with the wine. Pour in the cream and let everything boil down a little.
In the meantime, finely chop the tarragon leaves. Mix the tarragon leaves with the freshly grated Parmesan into the sauce. Bring to the boil briefly. Spread the turkey schnitzel on plates and pour the sauce over them.
