Refried beans anchor this entire preparation by providing a dense, starchy base that absorbs excess moisture released by the vegetables during baking. Because traditional refried beans often contain lard, swapping them for a vegetarian variety made with pinto beans and vegetable oil keeps the dish strictly pescatarian without sacrificing creaminess. When substituting canned beans, whisk in a tablespoon of lime juice and a pinch of cumin to replicate the depth of traditionally prepared versions.
Using frozen, pre-cooked shrimp requires careful handling to prevent rubbery textures, as protein that has already been cooked will toughen significantly if subjected to prolonged heat. Raw shrimp, conversely, releases more liquid into the glass baking dish, requiring a thorough blotting with paper towels before assembly. Thawing frozen crustaceans overnight in a colander set over a bowl ensures proper drainage while maintaining food safety standards below forty degrees Fahrenheit.
Corn tortillas form the structural layers between the seafood and melted Monterey Jack, offering a naturally gluten-free alternative to wheat flour products. Commercial corn tortillas tend to break if folded straight from the package, so warming them in a damp paper towel in the microwave for thirty seconds restores their flexibility for layering. Stacking six to eight tortillas snugly across the bottom prevents the filling from leaking through to the glass pan.
Baking the uncovered casserole at 350 degrees Fahrenheit for fifteen to twenty minutes melts the cheese completely without overcooking the seafood proteins. Allowing the finished dish to rest at room temperature for ten minutes before slicing lets the starches in the refried beans and melted cheese set, yielding clean squares instead of a loose scramble.
