Go-To Crawfish Etouffee

½ cup butter

1 onion, diced

1 green bell pepper, chopped

1 bunch green onions, chopped

2 stalks celery, chopped

1 (10.75 ounce) can condensed golden mushroom soup

¾ cup chopped fresh parsley

1 teaspoon Cajun seasoning, or to taste

salt and ground black pepper to taste

2 pounds crawfish tail meat

Melt the butter in a large, heavy skillet over medium heat, and stir in the onion, green bell pepper, green onions, and celery; cook the vegetables, stirring frequently, until the onion is translucent and the vegetables have begun to soften, about 10 minutes. Stir in the golden mushroom soup, parsley, Cajun seasoning, salt, and black pepper, and bring the sauce to a boil.

Gently mix in the crawfish tail meat, and simmer until the crawfish tails are opaque, 10 to 15 minutes.
