Cheesy Shrimp Mac

Preheat oven to 350°F. Coat a 3-qt. rectangular baking dish with cooking spray. Cook macaroni according to package directions; drain. Return macaroni to pan.

Meanwhile, in a large bowl toss together shredded Swiss and Gruyère cheeses, flour, and garlic. In a large saucepan heat broth and wine over medium just until bubbles form around edge of pan. Add cheese mixture, 1 cup at a time, whisking constantly after each addition until cheese melts. (Mixture may not be completely smooth at this point.) Do not boil. Remove from heat. Stir in shrimp and seafood seasoning.

Pour cheese mixture over macaroni; stir gently to combine. Fold in cubed Swiss cheese. Spoon pasta mixture into prepared casserole. Sprinkle crushed crackers evenly over top; dot with butter.

Bake, uncovered, 35 to 40 minutes or until bubbly and topping is golden. Sprinkle with green onions.
