These Shrimp Boil Foil Packs are the easiest (and the tastiest) dinner to whip up on weeknights and beyond. Individual foil packets are loaded with shrimp, andouille sausage, potatoes, and corn all smothered in Cajun spices and garlic butter sauce! Little to no clean-up + this recipe can be cooked up in the oven or on the grill!
