Drizzle the frying pans you just removed the pork chops from with olive oil and saute the onions until they turn soft.
Add the mushrooms and sprinkle with 1 teaspoon of the Garlic and Onion seasoning mix. Saute until the mushrooms are browned and half the size.
Add the flour and mix.
Deglaze the pan with a bit of the stock. Then add the remaining stock and spices and bring to a light boil.
Turn down the temperature to medium and simmer for 5 minutes. Whisking occasionally.
Add the cream and simmer an additional 5 minutes, whisking occasionally.
Season with salt if needed.
Pour the gravy over the top of the chops in the casserole dish.
Cover with tinfoil and bake at 350F for 1 hour
