Saucy Skillet Fish

1/2 cup all-purpose flour
1-1/4 teaspoons salt
1 teaspoon paprika
1/8 teaspoon pepper
2 pounds halibut, haddock or salmon fillets or steaks
1 medium onion, sliced
1/3 cup butter
1-1/2 cups (12 ounces) sour cream
1 teaspoon dried basil
1 tablespoon minced fresh parsley 
 
In a large resealable plastic bag, combine the flour, salt, paprika and pepper. 
Add fish and shake to coat (if using fillets, cut into serving-size pieces first). 
In a skillet, saute onion in butter until tender; remove and set aside. 
Add fish to the skillet, cook over medium heat for 3-5 minutes on each side or until the fish flakes easily with a fork. 
Remove fish to a serving plate and keep warm. 
Add sour cream, basil and onion to the skillet; heat through (do not boil). 
Serve over fish. 
Garnish with parsley
