Swiss Steak Sour Cream Casserole

2 teaspoons olive or vegetable oil
1 cup diced onions
1 cup sliced mushroom caps
2 teaspoons all-purpose flour
1 1/2 cups water
2 envelopes instant beef broth and seasoning mix
1 tablespoon grated Parmesan cheese
1 teaspoon Worcestershire sauce
1/4 teaspoon paprika
Dash of pepper
4 (5 ounce) beef top or bottom round steaks, broiled until rare
1/2 cup sour cream
1 tablespoon chopped fresh parsley

Preheat oven to 350 degrees F.

In 10-inch nonstick skillet heat oil; add onions and mushrooms and saute, stirring, until onions are translucent. Sprinkle flour over vegetables and cook, stirring constantly, for 1 minute; gradually stir in water.

Add broth mix, and stirring constantly, bring to a boil. Reduce heat and let simmer until mixture thickens.

Stir in cheese, Worcestershire sauce, paprika and pepper and remove from heat. Transfer steaks to 2-quart casserole and pour vegetable sauce over meat; cover and bake until steaks are tender, about 45 minutes.

Remove steaks from casserole and set aside.

Spoon 2 tablespoons of vegetable sauce into sour cream and stir to combine; pour sour cream mixture into casserole and stir until well blended.

Return steaks to casserole and serve sprinkled with parsley.
