For the house seasoning
For the sauce
1) Mix the ingredients together and store in an airtight container for up to 6 months.
2) Season the steak strips with house seasoning, then dust with flour. In a large skillet, quickly brown them on both sides in the olive oil and butter. Remove the steak from the pan.
3) Add the onion slices and mushrooms to the pan drippings. Saute for a few minutes, until the onion is tender. Sprinkle with 1 teaspoon flour. Put the steak back into the pan with the onion and mushrooms. Add the mushroom soup and beef stock. Cook over low heat for about 30 minutes, covered. Adjust seasoning to taste, adding salt and pepper, as needed. Stir in the sour cream the last few minutes, right before you serve. Serve over cooked noodles.
