3 pounds fresh medium shrimp, peeled and deveined
1 1/2 cups butter
1 cup chopped onion
1 tablespoon dried parsley flakes
1 tablespoon Worcestershire sauce
1 teaspoon salt
1 teaspoon ground pepper
1/2 teaspoon dried basil
1/2 teaspoon dried thyme
1/4 teaspoon garlic powder
12-ounce package thin spaghetti, cooked according to directions
8-ounce package processed cheese, cut into 1/2-inch cubes (I use Velveeta.)

Heat oven to 350 F. Add shrimp to a 9-inch-by-13-inch baking dish and set aside. In a large skillet, melt butter over medium-high heat. Add onion and cook, stirring occasionally, until tender. Stir in parsley, then add Worcestershire sauce and remaining spices. Pour mixture over shrimp in the baking dish. Bake 25 minutes, stirring occasionally. Remove from oven and stir in cooked spaghetti and cubed cheese. Use tongs to toss. Bake 5 more minutes or until cheese is melted.
